...so I finally remembered the Spec C... and man do I wish I didn't.
I found 1 cure for it: N3/N1 stagger makes it ok. Anything else is just not worth it... you can drift it with the ebrake on 50% of the time but it's just not very fun.
If you decide 2 steps of stagger is ok, then don't worry about the settings.. just keep everything default-ish and adjust the VCD to your liking. I seem to like 50/50 distribution.
I did find some settings with just the normal N2/N1 setup that were slightly BETTER, but still not good...
------------------------------------------
Springs: 10/6 (hard to say which settings I liked here, it was rubbish anyway)
Height: 100/120
Bound: 3/2
Rebound: 7/5
Camber: 2.5/2.0
Toe: whatever, doesn't seem to matter...I was hoping this could be the solution
Stabilizer: 2/5
LSD front: 25/25/10
LSD rear: 10/40/20
VCD: 50%
Ballast.. a lot, all the way back.
Brake balance: 1/20 (yea i know, I was getting angry at this point)
-----------------------------------------------
Biggest problem areas:
- Engine. It feels weak and choked like it has a tiny torqueband, even though it doesn't
- ABS?... Every AWD in GT4 has a tendency to understeer, but this one just will not kick the rear out when braking. It'll change direction quickly when e-braking, but the foot brake just makes it plow.
If you can sort out those two issues, then this car may have some potential. I wasn't able to.
