Fastback looked like it was accelerating where the notch was braking.
Fastback has a lot of body roll for sure and quite a bit of weight transfer towards the back. I'd think about some spring rate changes if you can. High rear spring weight would help. Shock tuning could band aid it.
where are you seeing push? Any pics of the fastback from the front while mid corner with even throttle?
You'd be surprised how stiff the springs are, I have .685 diameter "big block" springs, most people performance oriented folks are running 620s. Its not easy to compress the front end. In the back I have 5 1/2 leafs and the front half of the springs clamped solid. Really makes it fun braking deep into a corner, clamping the springs, there is no axle wrap. Opentracker turned me on to this trick. Plus I can do sweet burnouts. You'd think that would be rock hard but I think they are Grab a track, not the best metal so its stiff but not buckboard hard.
In the hard roll photo I came into the corner very hot, braked very hard and tuned in with the fronts just tiniest push but was hit the cones deeper than where I wanted to be, the photo was taken at the apex where the trail braking just ended. The second photo I'm transitioning to a throttle run into the sweeper. Think I'm just driving too hard...
I was running the red Koni's full rebound on up front and about 1/3 out back. I just dropped the fronts to half before this autocross, didn't really notice any difference. The end of the day I was running 42 lbs pressure up front and 24 lbs out back. I'm also running a Watts link set all the way up which seemed to help a little with giving me some twist on certain corners. 1" sway bar up front none out back. 1/2" Shortened A arms up front 1" shelby drop
It bites well on flat surfaces if I brake hard into the corner and trail to the apex but NO oversteer at all. There was this sweeper though and when my foot came off the brake and I crested the crown of the road, she pushed like a janitor's broom right off the line costing me seconds not fractions of seconds and probably a few $$$ of tire. I think I blew it coming in to hot for the crown. I'd like a little more oversteer just cause its more fun to drive.
