I agree with wing feather. However if you buy cheap you get cheap. As with all coils there are low end models and high end models.
I have Godspeed 2009 hyper RS coilovers on my 89 coupe. they are 16 way damp and fully adjustable. camber in front.
front springs 10k and rears are 12k. cost me a little under a grand. they are stiff but i love them. never any problems
I slide my car once a week so...... everyone has something bad to say about everything. And i still run a boosted single cam
At any rate buy the set up for what you wanna do.
