I have decided to upgrade my wheels and looking at a 21" wheel. Looking for something bigger than stock and 22" looks too big for me. Most likely it will be a 21x9F and 21x11R. I might even see if I can go wider in the rear. I'm also considering a 20/21 staggered setup. I would like to hear from those of you that have done this on what is the best tire size setup I should go with on this setup? Is there any formula that I need to follow on rolling diameter front to rear? It looks to me that OEM has about a 1" difference.

 

What about something like this?

 

These are very nice. What size wheels and tires are you running with these?

 

Here's a teaser we just dropped. We are running 21x13.5" at the rear with a 355mm tire. But we can go with your desired specs for the wheels.

 

What size wheel and tire are you running up front? Any concerns that the 355 tire in the rear is going to be hard to get in the future? What lowering springs did you use on this car?

 

Anyone know of a good source to get tires? In particular, I would consider the 355/25/21 option like above in the rear if I could find a good source that sells the tire. Everyone is on backorder.

 

nicely done..

 

Anyone else running 355/25/21's in the rear of your GT? Would love to know if you have any problems and how it rides? It sure looks nice.
