btw, i will not believe if u say there's no sign of rubbing. not the top fender but the fender lining in the front when u turn the steering lock to lock. no touching on 20'' with current tire selection on 996s = impossible.

If the added weight of the 20s eventually damaged the hub sensors or steering angle sensor the PSM / ABS warning light would come on. Other cars it would be ESP/ TC/ ASR, whatever. Anyway we have one customer that insisted on putting the 20in Avus on his car. With PSS9's there was no rubbing, it may drive a bit goofy, but if it makes a customer happy (who never tracks the car or really drives it very fast in manhattan), then so be it. Personally I would only put 18's on my car. Thats what it came with and was designed to run on thats whats gonna stay, just like on my 964 with 16's and my 356 with 15's.
Attached is a pic of the car with 20's looks kinda gangster but I think we all agree its not the setup to make your car fast or handle well!

Don't have a side shot. All the other pics I have of that car where before the AVUS rims. You are right the 3.6 does look sick with the Speedline 18's that came standard. My 964 is a 1991 narrow body cab. It came with 16's. Going up to a 17 would probably be ok but I have been told the goofy looking 16s were the lightest and best suited for the car. I believe they are the "Design 90" wheel. For a while I had been looking for a set of the 17in Ruf wheels that were specific to the 964 ( I don't think they make them anymore) but these wheels have grown on me. At this point they are "vintage"

Here is one from a little more distance. They used these wheels on the 964 3.8, Turbo 3.6 and Turbo 3.3 S (Europena version).
The 18 speedlines did weigh more, but my 1990 actually handled better with the 18s. I think the wider contact patch really helped this car and really kept the rear end planted on the track. Roll bar and track suspension did not hurt either. This car was great on the track and drove as well as my twin turbos at very high speeds. I have never driven any other pre-993 Porsche that was as smooth, stable and predictable at high speeds.

I love the look of 20's, they look freakin fantastic.
BUT I'm not sure if DOT has an approved tire and if there is an issue, there could be a legal issue to deal with.
I have a friend with a yellow M3 (carbon hood, trunk, sweet machine) - totally custom and if you live in south florida you might know the car. Anyway he has 20's on his machine and was on I-95 and hit something in the road and bent the inside of rear wheel. The tire sidewall is EXTREMELY low.
I settled with 19" HRE 545R's on my car and it looks and performs great. Just my .02. NOW if I had a 997, 20's all day long. I have 20's on my E500 benz just FYI.

No, that is incorrect. The profile number is calculated as a percentage of the tire width. It is not a static value.
305/25 has a thinner profile (sidewall) than a 315/25.

As long as the car isn't driven hard or on the track I'd guess things will be fine.
