as said i have a problem, i recently bought a set of audi s3 alloys 8l off my mate and have put them on my car, my a3 is a fwd if that makes any difference to fitment.
only seems to happen on the dual carriageways and only when im accelerating past 45, when i let off the accelerator it does judder a bit but no way near as much.
now, i know what your thinking.. wheel balance. his car was involved in a crash so possibly even bent or nackered wheels. but this morning i went to kwik fit and had them all balanced with no issues at all. if they where bent in any way they would have shown on the balanceing?
my front brakes however, are quite bad, they scrap and are pritty much metal on metal (i have ordered a new set of grooved disks and mintex pads which are on the way) could this be my problem?
i only really noticed they where this bad when i took my old wheels off and noticed how low my pads where and the nice groove on the back of the disk. and tbh, they have got a lot worse since i bought the car a couple weeks ago.
but i never had this problem with my old wheels?..
ive also checked tyre sizes, all the same, the rotations are on the right way, though 1 tyre just says outside with no arrow. im guessing that just means the tyre has to be facing outside.
im pritty sure its not a missfire, engine sounds fine and accelerates. just seems to be at its worse in 5th accelerating past 45 on some sort of carriageway i dont really notice anything on normal roads even past 50.
its defo coming from the front, im not running spacers, its not lowered though its a sport so -20 mm standard i think.
any help/advice is much appreciated i really dont know what this is :/
