Hey Guys,
Here's a question on braking bias and how to solve a little occasional rear hopping. First the stats on the car:
911T Front Suspension including rotors and calipers
'87 944 Front rotors and 914-4 Front calipers on rear.
23mm torsion bars front, 250lb springs rear
Bilstein shocks all around.
22mm Front Swaybar, 16mm sway rear.
Prop valve replace by brass T.
Porterfield R-4's (fronts) all around
Issue:
On the track I love the brakes...not fading (I know, i'm not going fast enough) and it feels really balanced. On auto-x courses under HARD braking I get rear wheel hop. I have to admit that with more seat time I'm getting smoother and even my braking is getting better and the hopping is going away. But it's still there a little.
My question is: is it all driver modulation related? or is the mechanical balance off? On the tracks it's great, but I get it occasionally on the auto-x courses.
Thanks,
Bill
