theres nothing to deal with when it comes to adj suspension..... all you do is open the hood and use the key they give you adjust the suspension. takes me 30 secs. Like 3 turns of the key would be a stiff ride i believe and 1 turn would be a mushy ride. No hassle what so ever. I never adjust mine though, always keep it stiff.

I dont think youll regret it. IMO much better than the saleen kit.
Theres also a slightly used dspec kit for only 400 on ebay right now.
