So the car is basically just for autocross and track, although I do drive it to the track most of the time. I've accepted I wont have suspension this year so now I just need to decide what to get.

I run in STU (autocross) and T3 (Time Trials). I require coilovers that keep the spring in the stock location (keep in mind this changes the spring rate dramatically over a true type rear coilover).

What I'm looking for;
Double adjustable
Rebuildable/Revalvable
Digressive valving
Front spring rate of about 1008 lbs/in (18KG)
Rear spring rate 896 lb/in (16KG) (again in stock location so about half that at the wheel)
Inboard spring mount, prefer some easily adjusted
Trying to keep it under $5k all in.

What I'm considering, MCS and Penske are a bit spendy.
BC now has double (ER) and triple (ZR)adjustables.
Their double adjustable ER has available digressive valving, rears default rate is pretty close to where I want to be, fronts are way soft. should be able to have them built to suit at a cost. ZR's are a bit pricey before they start wiht the upcharges, might as well, go to one of the big names. and I'd pretty much be on my own for rear spring mounting.

Redshift doesn't yet offer support for the Z34, which is weird since they support the Z33.

MCS or penske, hence the name.

Feal is about the same money as MCS or penske.

History:
I tried initially ordering Penske from Strano (awesome guy but he just doesn't know the chassis). Agreed to cancel order so I could order from someone who knows the chassis better.

Discovered Diftech sold not just awesome rear spring mount but they could build the penske's and they know the chassis (Doug is a very knowledgeable guy, but flakey). After two months and no finite shipping time frame, he agreed to refund my purchase (on the 60th day, last day I would be able to dispute the change on my card) and let me know when they get the needed parts (haven't heard anything since).

Thoughts?
