I used a rx-8 as my professional team car for about 5 months straight. I cant give you the exact tune but go for about 8.8 in the back and maybe a 4.8 in the front dampers Front 5 Rear 6 on both damper and swarbars f a r both 7. Let me know if that works.
Oh and make sure to have negative camber front and rear. -.20 in the front and -.05 in the back. also -10 ride hight front and rear to eliminate any kind of body roll
toe is just .5 in the front and 0 in the back. lsd set to 55 55 55 for all of them. and full upgrades on everything and a midrage turbo so about 476hp fully broken in.![]()
The RX-8 has a much more usable powerband with the supercharger than a turbo, just FYI.
Most important thing for an Rx8 I'd say would be a good transmission tune and a mid range turbo/supercharger as oppose to a good suspension tune.
