A note on the Rear Diffuser

The Final Edition Rear Diffuser is coming soon. During final fitment checks we identified tolerances that didn't meet our standards, and we're not comfortable shipping a part that isn't right. We'd rather take the extra time to get it there than put something out that doesn't live up to the rest of the kit.

 

We'll have an update on timing soon. If you want to be the first to know when it's ready, sign up to be notified.
