search...

 

find someone in your area with the hks exhaust so you can hear it in person.

wheels, possible to do 9.5s all around depending on offsets.

 

what would your offset need to be. whats a good place to find wheels on the internet.

 

what would your off set need to be in the front and back for this to work

 

Try reading through this thread. It will be enlightening. OK
