Did you get springs too? If so what kind? Let us know how the Front Pro. Bar goes in.

Gert forgot the springs!! Whoops. He is sending them today MO33 springs as promised on his website. The bar looks fairly simple. I will post a picture once installed. Came with one page instructions and bolts to underneath of trunk pan. Also, since my bellows and bump stops are old and worn, I am having those replaced as well.

Any of the people here have RS front uprights and steering rods?

I wonder if the problem is bump steer? Or compliance in old rubber?

Reason I ask is my car is stiff but actually rides fine on the street for me and I have no issues with stability, trammeling or "darty" behavior at RS -10 ride height and RS camber full neg, caster and toe with a careful cross weight check. My tender springs are fully compressed at ride height.

Set up:

Front
RS uprights
Supercup struts revalved by Bilstein
H&R springs 400 lb/in (143# tenders)
GT2 tie rods
RS monoball strut mounts
RS stab bar on full hard
BBS 18 X 8.5" wide wheels
Michelin Pilot Sport Cup 224/40
Walrod control arm bushings

Rear
Supercup coilovers revalved by Bilstein
H&R springs 686 lb./in (143# tenders)
RS monoball coilover mounts
Solid sub-frame mounts
RS stab bar on full soft
RSR monoballs in all links
BBS 18 X 10" wide wheels
Michelin Pilot Sport Cup 265/30

Yes, I think the issue is bumpsteer and the geometry is out if not running the RS uprights. As I asked JB911, the dartiness is minimized at taller ride heights. Not everyone has the budget for RS uprights.

The only reason I have the budget is that I do my own installation and other mechanical work. If I were paying $100/hour or whatever to do the mechanical work, then it would be out of reach for me.
