FM butterfly brace
I have a turbo from Midnight Performance. I know they got parts from you folks to make my car work. I push 248 lb-ft to the wheels and have stronger transmission rear end and a whole bunch of goodies. I run 225/45/15 R-Compound tires on this 1992 with 245,000+ miles. The frame used to twist so badly that it was scary to drive fast. At first I had a pair of custom doorbars welded between the firewall and seatbelt tower brace (with a tie in to the floor by the seat). That helped. But running 2:02 laps at ThunderHill was very worrisome with the unpredictable manners the car had. It would go from a push to a snap oversteer at high speeds. You simply could not drift the car - or weird stuff would happen. And forget about dropping the throttle mid corner! But after I installed the FM Butterfly Brace - MAN it drives like a Spec Miata with a full roll cage - except it's have more than twice the power. What a BLAST!
So - the only problem is that if you look carefully at one of the photos, you will notice that I need some downforce. My wheels appear to be OFF the ground. Do you have a wing or something that can keep me pressed against the tarmac?
