    Default Alpine GTA Excessive Rear Tyre Wear

    I recently had my rear tyres replaced on my Alpine GTA v6 Turbo after noticing excessive tyre wear on the inside of both rear wheels. The car seems to have quite a bit of negative camber on the rear but camber is not adjustable - only toe in and toe out. I am pretty sure that the toe in and toe out are right although will have it rechecked. I have been advised that the springs might be the cause and might need replacing. Has anyone had similar problems and what was the fix?

    Everything is adjustable, its just that some things are easy to adjust and some are bloody difficult.
    They say a fuego's camber is not adjustable either, but I beg to differ.


    First thing to check is correct ride height.
    You'll need a body book for the specific dimentions.
    Lowering the suspension usual introduces neg camber so if the beast is dropped, that might be the cause.


    Alternatively, stop driving slowly on straight roads and do some more fanging around corners and that might even out the wear.
    Good luck,

    if you adjust the toe you can even the wear due to camber

    what you need to do is find someone who is willing to adjust on experience and not the book

    i have been running neg camber on 504's and 604's for years and by getting the toe right results in even wear across the tyre

    Hi Bazzamac

    I would also check the bushes for wear when you get the wheel alignment done, the rubber in the bushes may have gone soft and causing excessive movement

    The problem is that you have gone from 15" to 17" rims with a loss of sidewall height and ability for the tyre to conform with the standard camber.
    I had to decamber my GTA back to about 0.7 neg by slotting the top wishbone mount points and then welding large washers in place after the position was set.

    How much do you have now? You could still slot the upper arm mount and move the arm inwards, I just don't know how much you would give it given wide rims and 40% tyres. Maybe 2-2.5 degrees if you are looking more for track performance. I run 4.5 neg on my race BMW 2002, but I wouldn't recommend that for a sometimes road use car as tyre wear would most likely be a problem, also you don't get as much tread contact under brakes.

    I agree 2-2.5 deg neg camber would be ideal , not too worried about the wear as there is not much weight on the front but would not want to loose any braking performance. I just had a bit of a look and slotting the upper mount is easiest and maybe make some special elongated washers to hold position.

    Thanks everyone for your advice. Will be looking at the problem once I get my A110 sorted for the Canberra French Car Day on 3 November. When you have time Alan, are you able to send me a PM with some details and photos of what you did to your GTA's rear suspension to correct the problem?
