Hey was just wondering if it's possible to put a 21 inch rim on a new Turbo or 4S. I found out that they now are making a 345 25 21 tire width. Dont think this is possible but hey you never know...don't rip on me guys... just think how much better those 21's will fill out those wheel well arches.

 

I am thinking of downsizing to 18" in my 997S for better handling, and you are going in the opposite direction?! Don't think 21" will look any better, but no better in performance for sure.

 

They are throwing 21's all over M5's and others these days, just seems that things are always going up not down...plus this is just for da street...I dont think 21's will look to big, I look at my 20's now and they look just a little small to me in the arches. Plus I'd love to have a 345 25 in the rear

 

I think 21" is a bit too much for a 997...you know sometimes I think some 20" wheel look a bit too big...

 

The Cayenne S coming will have 21's on it from the factory. I don't know how they would be on a TT though...

 

the killer is the price of 21" tires

 

21" on any sports car is silly.

 

I think you will have one bad driving P-car with 21"
Plus I do not think it is going to work, you are going to big (+4 cm over stock) compared to 0.5cm when you go with 20"

I think it will give you problems with the AWD system as well

Hey Bro. It's your choice but, you will be asking for problems in the suspension department and axles and rear-ends as well.. Good luck with your decision though!!!
