I'll have to weigh my TSWs with bald RS3s and post that weight up here. With all the focus on rotational mass and unsprung weight, the total wheel&tire should be accounted for.

 

Thinking of running 255/35/18 on a 18x8.5 rim +55 next year. You guys think the front will have clearance issue? I used to run a similar setup in my old car and really liked the feel of the lower profile tire.

 

Yeah your gonna have to at least roll the fronts to run that I am pretty sure. I ran a 18x8 +42 and it was danger to fenders zone at stock height. Maybe if you ran a lot of negative camber it might work.

 

Wow, with R-S3s the prices is $100 more per tire. Well at least they will be in stock.

 

You should actually be pretty good, especially since they're 8.5" width. I know people running +55 with 17x9 and it's not much different than the +63 that most people are running.

 

+55, 9" rim with 255 tires? So do you know how much camber is involved in that? I thought for sure that would mangle the fenders. 18x9 +55 is another option that's on the table. I'm currently around 13" hub center to bottom fender, with 3.0 camber.

 

The car I codrove at nationals was pretty much that - 17x9 +55, 255/40/17 dunlops, I'd guess around 13" hub center to fender (might have been slightly higher but definitely not much), and 3 degrees camber or slightly lower. I think Nick Jackson was running the same thing, not sure what his ride height was at that time.

Would the 18's still be the same overall diameter?

 

Rs3 and Star spec both list the 255/40/17 and 255/35/18 as 25" diameter. It seems most people run minimum 60 offset, that's why I was a little hesitant about +55.

 

do you guys run the same offset F/R?

 

The most common wheel configuration for STR is 17x9 with offset of +63 (949 6ULR) or +62 (TR Motorsport)
