many,many people have run them for years, some quite quick stock suspension cars too. I think they are the oldest damn LCA's on the planet LOL...... I personally never ran them but alot of fast cars have in the past. I have the granatelli weight-jackers on my car (the weight-jacking function is now obsolete with the new coilovers) and they worked quite well. Plus it gives you the option of changing ride height I think +/- 2.5? Mega-bite juniors work well also. Anything adjustable is good. I run the double-adjustable uppers too...........
