just get the biggest one available..

 

There is some guy I work with that tells us that he dosent LIKE the large wing on his Rx7 with front mounted intake(intercooler if you ask him), but he NEEDs it because it keeps the car from flipping over backwards when he goes over 170.

So I could easily see your application for a large wing. As said earlier, its all about downforce!

 

This wings hot... I say get one similar to this one. but maybe just a bit smaller so people dont think its too ricey.

 

hahahahahahahahhahaha
oh man u made my day
