Looking to add a spoiler to my 2000 formula. Primarily for autocross but will be breaking into road course as well this year. That puts out the 10" I originally planned on. I've been researching blaine fabrication's lexan spoilers and considering the 7.5" to be a good medium for the 2.

Anybody have other experiences?

 

In my experience, something that works well for one application will not work well for another. A compromise will always be just that - a compromise.

I would make two different spoilers, one for each application. They're not that hard to mount and dismount. There are lots of ways to make them easy to R&R, from fancy to cheap.

 

If you use a Blainfab spoiler, it's adjustable. So you could get the 10" and adjust it up for autox and lay it down for road courses.
