Arraut MS is great, you let em know what you're looking for as far as ride and they're very helpful. Same products as being sold by others, sometimes 1/2 the cost. I like their set-up for the coilovers and would probably pair that with Bilsteins for a great ride. Do your research as to spring rate and if you want a good ride that'll last, pay the exra $$$ to have to strut rate matched to the springs. Arraut MS has great trailing arms and stuff too. If you're going to stiffen up the suspension and lower it I would suggest upgrading all components, I.e., sways, strut tower braces, poly bushings all around, check your engine and tranny mounts, strut mounts, etc. To do it right, expect a 2-3 grand overall : )
Good luck!
