for an 18" lightweight track setup i would highly recommend going with our Blonix F/10 wheel with our Race Prep Package (+$100)
We can do a matte gunmetal which is part of our standard finishes so its no extra charge!
The Blonix F/10 is one of our best performance wheels. Very little flex, and extremely strong, yet light as all hell!!
Please send me an email and we can get started on your wheel setup ASAP!!
