Just wondering the effects of using a 20mm front bumpsteer kit on the front rack. My car is lowered just about 1 3/4" all around. And are the rear roll center kits a tried and true investment or a waste of money.

Second, my s feels like the rear is walking on me when I hit high speeds and curves. 12k front 11k rear springs. I'm at about halfway on the rear damper, just wondering if going harder on the damper will help or maybe my spring preload is not enough in the rear, or my rear toe is out and that's why the car wants to squirm that little bit. Need to solve this problem pronto. Thanks
