    Audi engineers their cars to Understeer for safety reasons (See the MK 1 TT for the results of a neutral setup [img]/ubbthreads/images/graemlins/crazy.gif[/img]) So your problem is not necessarily tire related [img]/ubbthreads/images/graemlins/grin.gif[/img] I run 245/45/17 GSD3's in the Spring/Summer and they hold better than my old Conti SC2's, but as always, if you push them hard enough, they will slide [img]/ubbthreads/images/graemlins/angel.gif[/img]

    Think i'll stick with the Pilot sports then, as these are very predictable and great in the wet.

    The slug, I drove a chipped S3 with the michelin and found them very good in the wet.

    Check the thread about my 3.2 and you'll see that even Guru Ess-three find all audi's understeer when stock so not worth changing the tyres.

    Anybody tried upping the tyre pressures at the rear. I've read this works to a degree on the track so would probably work just as well on the road. Tyres will wear out quicker though [img]/ubbthreads/images/graemlins/grin.gif[/img]

    Yeah, if you have a look at Jojo's track-day thread on the 8L forum, you'll see he played with tire pressures. You'll also see what some people have to say about fr/rr pressures.

    Playing with tire pressures is free! Use it at will and as often as possible, until you find what's right for you.

    Genereally, on a fwd car, more rear pressure will let the rear come round easier, thus negating some of the built-in understeer...


    H&R have a set of adjustable anti-roll bars for our audis on their catalog (8P and 8L, fwd and Quattro).

    Yeah i know by adding pressure to the rears will give more oversteer, but as a result of more unstability with less tyre tread on the road..

    What sort off pressure you running, cause my car was oversteering (quattro) a little and ive upped the pressures to 36 all round and handling is much improved (19, 235's)
