I have FINALLY finished just about everything for my coilover conversion in my 1978 280z with Stance coilovers. I also have TTT control arms. I am at the point of dialing-in the ride height. Stance gave me four 6" threaded sleeves. I had them welded right to the hubs in the front and 3" above the hubs in the back. I was hoping to maintain stock height or maybe 1" lower than stock.
Well after getting everything on and lowering the car, it looks like the front was lowered around 1" and the back was lowered around 2". I would like to crank the rear up another inch. The problem is, the threaded sleeve is currently only on by about 5 threads in both front/rear. I am afraid to crank it up in the back because I feel like the coilover will sheer off if I go any higher with so few threads holding. So my questions are...
How many threads are "safe" when screwing the sleeve into the coilover?
I have not done anything with alignment, track width, etc. Will any of these affect my ride height?
What are my options for raising the car if I can't unthread the sleeves anymore? Can I use a top-plate spacer or something?
