Suspicion confirmed, staggered Caravela wheels will fit the STR without a problem, absolutely no rubbing of any kind. The back looks close but it does fall within the wheel well and will not hit the top in the event that the back end is brought down for any reason, skinny or low profile tires are not necessary. These happen to be powder coated matte black, it think it looks pretty good.

Btw, im selling my 18 inch Vulcan wheels/tires, PM me if interested

 

Looking good!

For future reference, What size are the wheels front and rear, and what size tire you have on there?

 

wheels measure 8.5x19 (front) and 9.5x19 (rear). Tires are michelin pilot super sport 275/35zr19 (rear) and 245/40zr19 (front)
