under "door check strap replacement". It gives you some info.
As far as springs, I have H&R's with HD Bilsteins with one bump spring pads at front an 3 bumps in the rear. Some people do not recommend that set up (vs H&R's and Bilsteins Sport) but the car seats just right and it works for me.
You DO have other choices, like Eibach and MB Sportline. Less agressive than the H&R's, in that order.
Your car, your choice.
