Have fitted OEM RSTTs to my S3 today in place of the standard 17" Avus wheels. Before fitting I weighed the wheels (couldn't find the info about relative weights) and found the RSTTs to be approx 3 lbs heavier. I wanted to get lower profile tyres on the car to aid handling but was worried about this additional weight doing the opposite.
I am wondering what other peoples experience has been in terms of handling when making this change. First impressions are not that impressive but I have also had 4 new F1s fitted today and I'm sure these will take a while to wear in. I've set the pressures to 34 front and 38 rear (was running 30 front and 34 rear on the 17s which seemed to give good front end bite).
I know I'm being impatient and need to give this a bit of time before making up my mind but I'm interested in other views about the differences before and after.
Couldn't afford good lightweight wheels by the way.
