Hmm, what are the spring rates on the H&R springs - they don't seem to be listed on the table
here. I'd prefer something that would give handling characteristics somewhat closer to what the BRZ has, plus about 25mm drop in ride height.
I didn't know Martelius makes an exhaust for the GT86 as well. Did they custom-build it just for your car or is it a design they will be selling as a product?
Can't make it today for a meet, so we'd have to try sometime next week. I'll drop you a PM with my contact info.
