First modification to make to your GT3 is replacing those airbag-warning-defaced visors. Decal-free version is available from Carnewal ("karn-wall"): www.carnewal.com.

Of course, you'll want to change the side markers, but those are widely available in the U.S.

Next would be the GT3 console.

I also like the GT3 seats for this car. And the rollbar if you'll use racing harnesses.

Once you've done these, the car is like the factory intended it - without DOT interference. (Except the rear bumper over-riders.)

 

have installed the euro seats. how did you solve the airbag warning lite coming on. is there a fix short of going to a dealer and having them reset the system. my nearest dealer is 500mi away.
