    Features/Model changes

    There have been a few model changes during the life of the VXR so far..

    Reg
    06
    - Carbon Fibre decal added to the B-Pillar
    - Chrome strip added to the door and rear window seal
    - Check Control removed
    Some 06 cars also had VXR emblem badges added to the doors, this was a short lived change and the badges were removed.

    07
    - Centre console changes from matt silver to piano black, strip on passenger side dash and in doors changed from carbon fibre effect to silver
    - From mid-April all VXRs are equipped with an Aux Input socket, so
    any MP3 player can be plugged in
    - Mats are no longer standard fitment

    57
    - Keyless entry now standard fitment
    - Optional 19" wheels are now two tone, anthracite and silver
    - Storage bin behind handbrake is now a cup holder

    Sport Button Feature
    This switch is on the centre console, its main purpose is to give the driver more response when driving on open roads.
    When activated the response of the throttle pedal is increased, so it doesn't need to be pressed as hard to accelerate.
    The steering response is also improved, so the wheel can moved less to effect the same rate of turn.
    From factory the sport button does not unleash any more power, however some remaps (see tuning section) do this.

          Options

          There are/have been a variety of options available on the astras.

          click any pic for a larger version

          Paint
          The car is available in four different colours:
          Arden Blue
          Black Sapphire
          Star Silver
          Red

          Note that pre 07 registration cars were a colour called flame red, later ones are power red. The difference between the two colours is fairly subtle, but easy to see when the two colours are next to each other, even in pictures, so check out the pictures section of the website here : http://www.vxronline.co.uk/forum/forumdisplay.php?f=46

          19" Wheels
          There are two version of the 19" wheel. The car was launched with an all silver optional wheel:


          From 57 registration on the 19" wheel is a two tone version:


          AFL
          AFL stands for Adaptive Forward Lighting. What this means is tha the headlights can move left to right, the idea is when driving at night the light will be directed around the corner, allowing the driver to see the exit of the corner. Opting for AFL is the only way to get Xenon lights on a VXR from factory, Xenons are not available without AFL and AFL is not available without Xenons.

          Normal headlight:



          AFL/Xenon:





          IDS
          Stands for Interactive Damping System. Basically when the sport button is pressed the shocks become harder, the idea is to give a firmer ride and to reduce bodyroll. Its quite a rare option as it is reported that the IDS is not set up for english roads and the stock suspension (passive) is better suited for our roads. At this time I'm unable to comment as I've not driven an IDS car. Note that if at any point in the future you wish to upgrade the suspension to coilover shocks the IDS option would be removed from the car.


          Climate Control
          All Astra VXRs get air conditioning, but this will simply blow cold/warm air according to the settings you set. With climate control you can ask the car to stay say a given temperature (say 20 degrees). As an added bonus the option also adds a better screen in the centre of the dash.

          Non Climate car:



          Climate car:



          In Car Entertainment/Sat Nav

          There are/have been 4 radios fitted to the astras.

          CD30
          The standard equipment for pre 06 reg cars. Single slot CD player and FM/AM radio.

          CD30 MP3
          The replacement for the above, now able to read MP3 CDs and display the track name on the centre screen.

          CD40
          Option, 6 CD changer (all in dash, no seperate cd changer). Doesn't read MP3 CDs. Was available early on in the model life and replaced by the below

          CD40MP3
          Option, 6 CD changer (all in dash, no seperate cd changer). Does read MP3 CDs. Was available up until 07 reg and has made a re-appearance on 5 reg cars on.

          CD70
          This is the Sat Nav option. Stays as a single CD player and also adds a colour centre console screen.

          Rear Parking Sensors
          Not much to say really, do what they say on the tin. The system appears to work very well and is something to consider given the cars' rear visibility.

          Leather Interior
          A relatively uncommon option, besides the leather the option also adds leg extenders on the front seats and 3 stage heaters in the front seats.

          Standard Interior:
          <pic to be added>

          Leather:
          <pic to be added>

          Keyless Entry/Push Button Start
          Option up until 57 reg cars when it became standard fitment. For more details on how to use it see : http://www.vxronline.co.uk/forum/showthread.php?t=2120

          Sight & Light
          A inexpensive option, this adds rain sensitive wipers and automatic lighting (i.e. if it begins to rain when driving the wipers are turned on and if driving whilst darkness falls the lights are switched on automatically).

          Folding Mirrors
          All cars have electrically operated mirrors, this option adds the facility to press a button inside the car to have the mirrors fold in against the front window.

          Cruise Control
          Doesn't really need any explanation, many owners have fitted this after buying their car.

            Tuners

            Tuning is often an emotive issue, eveyone has an opinion on which tuner gives the best service or has the best product. The best thing to do if you are considering modifications is to do your research (there is *alot* of information on this site) and find which products and tuners best suit your needs.

            Who are the main tuners ?
            At the time of writing the main tuners in the VXR arena are:
            Courtenay Sport - www.courtenaysport.co.uk
            DAP - www.dap-performance.co.uk
            Regal - www.regal-auto.co.uk
            Thorney Motorsport - www.thorneymotorsport.co.uk
            VX Performance Centre - http://www.vauxhall.co.uk/vx/microsi...tre/index.html

            Courtenay and Regal are long time Vauxhall tuners who are both well established in the market.

            DAP are relatively new but Dave (the owner) has a long history in motorsport for Triple 8 (who currently run the vauxhall BTCC cars) and other motorsport companies. Dave is hoping to campaign a Vectra VXR in the 2008 Dunlop Sport Max Cup championship.

            Thorney are again relatively new but have quickly become well established in the market. Aside from tuning road vehicles Thorney also prepare race cars and run their own race VX220s.

            VX Performance Centre is an offshoot of the Triple 8 BTCC team.

              CD40MP3 made an apperance in some cars. I believe this was limited to some 06 reg cars only and know of at least 2 that did have this radio instead of the normal CD40. Only difference was the ability to read MP3 disks but otherwise identical to CD40.

              Also the GID screen on the cars equiped with the CD40 was different to the one with just the climate control. I will dig out a picture for you later today.

                    Modifications

                    Stages
                    Most tuners market their engine modifications in "Stages".
                    Stage One is a remap
                    Stage Two is a remap and exhaust system
                    Stage Three is a enlarged intercooler and remap
                    Stage Four upgrades are currently in development, so details are not yet available, but its clear that it involves a replacement turbo (probably a garrett) and manifold.

                    Note that the remap for the stages are not the same as they take in to account the other modifications!

                    Remaps
                    VXPC, Regal and DAP use maps from a company called EDS in Germany.
                    Thorney use maps that have been developed in conjunction with Superchips
                    Courtenay maps are sourced from another German company called Klassen

                    You will find much written here and elsewhere comparing maps and giving opinion on the "best" one. In all truth the maps are probably as good as each other and can be adapted to suit your requirements by the tuner. The best advice is to decide what you want from a remap and ask your tuner to tailor it to your driving style.

                    Bluefin/iPF
                    Bluefin and iPF are handheld units that allow you to remap your car with files supplied by the tuner. The unit connects via USB to your PC so you can download maps, the unit is then disconnected from the PC and connected to the car, the map can then be uploaded to the car ECU from the handheld unit.
                    The benefit of these units is that you can remap your car on your driveway, you do not need to visit a tuner to get the remap. They also allow you to change the map in the car as and when it suits you.
                    It is possible to reinstall the original factory map into the car should you wish (if the car is going for servicing etc).
                    The handhelds also have other functions, such as reading DTC codes (error codes) from the engine ecu.
                    Bluefin has been developed by Superchips and Thorney.
                    iPF (intelligent flash programmer) has been developed by EDS, currently only available from Regal.

                    Exhausts
                    The most popular exhaust systems for the astra are Miltek, Remus and Magnex.
                    Again much has been written about x is better than y, however they are all quality items.
                    Both the miltek and remus are available from Vauxhall main dealers (Miltek part no: remus part no: ), both are turbo back systems.
                    Both have a lifetime warranty.
                    Early Miltek downpipes had a design fault, resulting in some splitting. Naturally these downpipes are replaced under warranty, furthermore the design has been changed and so far no new style downpipes have split.
                    The miltek is available in two styles - the first (original) system has a front silencer box, the second has a straight through pipe to replace this silencer box.
                    The magnex is only a cat back system, so you need to source a cat and downpipe if you want to use this system, some tuners can supply these components and the magnex to make a full system.

                    Suspension
                    Eibach springs come highly reccomended as a quick upgrade to lower the car and improve the handling.
                    If you want to go one step further there are coilover cnversions available from Eibach and KW.
                    DAP have just released details about a new coilover setup from AST.
                    The astra has no rear anti roll bar from Factory, but VXPC have develpoed one that is available from most tuners.

                    Brakes
                    The two popular brake upgrade options are from AP Racing, this replaces the front discs and calipers with 343mm discs and 4 pot calipers.
                    Alcon also do a similar set up.
                    AP Racing kits are available from your main dealer (part no: ) as well as the tuners
                    Alcon kits are available from Regal and DAP.
                    If the budget doesn't quite stretch to that Courtenay also offer standard size grooved discs for front and rear.
                    Courtenay also offer a set of cooling ducts for the front brakes, these attached to the lower suspension arm and direct cool air to the brakes, this is an inexpensive mod that appears to be quite worthwhile.

                      The way you've wrote it implies that the car has a variable ratio steering rack, which it doesn't. Pressing "the switch" Reduces the power assistance given to the rack, and so the wheel is a bit more weightier and improves feedback from the road - That's how I understood it anyway.

                        Dont think this correct either, the weight is added and the amount of turn is reduced.

                        Im sure someone will confirm and give the technical info

                          Sorry if this is in the wrong thread or section, but can someone tell me what this "stepper motor" thingy-ma-jig is,and what it function is in the speedo????

                            Just got back to this thread..

                            I dont know for sure but I suspect that the way its done is that the steering ecu looks at the steering column angle sensor with sport off if it sees say 10 degrees of movement it tells the motor on the rack to assist the steering so that the wheels end up moving say 20 degrees.
                            With sport turned on it does exactly the same but less movement of the steering angle sensor (lets say only 5 degrees) still results in 20 degrees of wheel movement.

                            Be interesting to find out for sure.

                            Dave, not quite sure what you mean, I suspect the speedo needle is driven by a stepper motor - cable speedos are a thing of the past.

                              the stepper motor is when you first turn the key in the ignition and all the needles shoot round to max,preety cool i think
