Only when launched hard, though, from what I've read. I want one of these for my KP60, but they're not easy to come by over here.

Might be JDM only? I thought it was all of the early ones, though. Any 5-speed RX8 is the same basic box.

True, I have two of them for my NA 4AGE into 700kg KP60 project, 1.6 litres of torque, less power than the factory engine for the box. Should be tough as nails in that context.

Good! This is what I wanted to hear!

This is how they look:

A straight long enough to allow a 115rwhp Miata to reach a top speed of 115+ mph. I'm OK with that in a fully caged tiny car, with all my safety gear. Aamof I never even think about it while racing. Then I consider this car that has nearly 3x the power and about a fifth the safety equipment and fear sets in. Can't help it. I'm a calculating person. :D
I understand the fear. Hampton downs has a straight that's not straight. I felt nervous through the slight right. Very nervous when the brakes faded. Nervous just doing 200kph+ in a ute toward a corner. The ute has a solution, though: Shit ratios. I was able to come out of the sweeper, hit the limiter in 5th @ 210kph ish, brake down to 120 again, then hit the limiter again @ 210, then brake for the corner at the end :-D How long is your straight? Let me see. No, impossible to figure out. And the straight at Hampton looks like a huge radius turn on a map, which is kinda what it is. Not as much fun, but set a speed cut to limit things on the straight? :-D
