I'm finishing up the finer details for track use on my '93 FD with Turblown 7670 kit, AEM AI, Ohlins r&t, and 255 Hankook rs4 all the way around on 17x10 Konig Hypergrams. Looking for a little more protection and ideally a bolt in half cage with harness bar and wondering what the best options are these days? Looks like the Samburg (sp?) one is NLA and I'm looking for one that will let me keep as much of the interior plastics as possible. Thoughts on the Autopower or AGI options? Does Kirk Racing still make theirs?

 

I was never able to find a good solution for a bolt in cage. I ended up having a custom half cage one made for about 700. My rear is gutted though and it looks like you are trying to keep alot of the interior in place. I do have experience with Autopower in my Evo X, not sure on the RX7 platform, but it was a nice piece and fit well in the car.

That's a little pricier than I was anticipating but does look like a nice piece....
