I appreciate both the comments and replays, truly!
Racer325: I have been trying to fix the looseness of the rear-end. On tracks like South City I'd assume messing with my rebound dampening so the rear won't bounce around like a kid with a sugar high, but I'd also think that'd mess with getting the throttle out on the corner exits. I'm not sure what I'd do to fix the problem, but I'll keep trying.
Bonehead3: First mate, I just gotta say your driving scares me.
But you did get up to a nice, quick speed on the straight down Blackwood, kudos on getting those brakes to work nicely. I should have uploaded my own driving replay in my first post for some decent critique, as some of the problem may also be my driving style. But I'm assuming not since there was a huge amount of sliding in both replays, but it bugs me since I cannot get that grip back there and not sacrifice turning ability.
If there's anything you two want to do to the setup that could improve it, or advice about how you felt with the setup, more detailed instead of describing it as weird, would be wholly welcome!
