All my three are 86, so not early but early offset. I think they do them for the early (pre 85.5) cars also. check thier website Ground Control

I have 250# 1" lowered Bilstein sturts on there at the moment and really like the ride, feels firm but comfortable. I could drive this car all day long. I certainly don't want to go any harder on this road car, it's become a daily driver and even with just 250's it still feels too firm over certain road surfaces/bridges/in the wet etc. I am comparing the ride to other p-cars and not a Buick in case anyone should ask. I like to feel the road but also be in control and not hop about over the slightest imperfection.

Agreed, my 250# springs feel great on the track with konis on stiff (and I could ask for something stiffer at those times) but I drive the car daily as well, and every day I wish I had softer springs even with konis on full soft.

 

Decided to go with 250F/400R springs (225F/225R effective rates) on the GC coil-overs, double adjustable at the front. Again, this is with MO30 and without t-bars. Tire choice/size not decided yet, but they will be mounted on my 17in Fikse LM5's 8F/9R.

Thanks for all the help and I will post feedback when it's all together.
