Welcomem to GTPLanet, wogus89!
Since I'm not a JDM fanatic, you'll have to tell me if that's the third-gen RX-7. The RS/RZ twins? I don't think of that as a drifter, despite the popularity - it's too much fun to drive it fast. Do you have the race setup? If so, try this on the suspension:
Springs: 10.8/10.0
Ride: 88/90
Bound: 5/6
Rebound: 6/8
Camber: 3.2/1.0
Toe: +0.5/-0.5
Stab: 3/3
Brakes:14/12 if you have the balancer
