Lee you will find the Gr. N Bilsteins are the
regular bilstein sport shocks, just that they have been opened up and serviced, and installed with different orificing for the higher damping rates.
If you look at the Gr.N catalog you will see different combinations of shocks listed in different valving sets. The Turner spec'd vavling is listed, as well as the setup I had. Going on that data, I don't see where the shocks were adjustable.
when my LF broke at Limerock, I had a replacement overnighted from Turner, which they had in stock from the revalving service center in California (where I originally got mine done). Turner spec'd their shocks slightly differently however, so later I sent the shock back to be rebuilt to my specs.
there is really no black magic to it. If you want an adjustable race shock, you will pay for it. Look into Ground Control's Advance Design shocks, they are the best value for the money, you can get a set for around $2k I believe. FYI, getting Bilstein's revalved is around $50 + shipping to California per shock.

I hear you
I bought a set of GR. N Bilstein revalved by Chuck Stickley (LTW #70 B Mod). You are right, they are not adjustable. Strange, as from the Motorsport GR. N catalogue, I understood that they had many settings, thus, were adjustable.
As of now, the front suspension consist of those Gr. N shocks with threaded body and 2.25 inch springs. One set of 300lbs tender springs and 650 regular springs on GC camber plates. Rear consist of those Gr. N shocks with GC adjustable height 2.25 inch 750 lbs springs.
I have not made a choice on the swaybars yet.
Front brakes consist of 13 x 1.25 directiobal vent rotors on aluminum hats with Wilwood calipers. A brake bias valve is connected in order to adjust the rear stock brakes.
Motor is 2.8 with Supersprint headers and Schrick cams. Pretty basic set-up.
Now I am looking for decent wheels that offer 1 1/8 inch clearance between the mounting face and the inner side of the wheel.
