I have an opportunity to pick up some low miles fr/rr boss 302 springs for a cheap price. My car is a 2010 Track pack with about 95k on the original springs. I know they don’t lower the car much(about 1/2 inch up front, less in rear), but I don’t really want to lower it. I just want something that’ll keep the car a little flatter in turns. I currently have Koni orange SRTs, and a boss 302 rear sway bar. Other than gt500 strut mounts and new stock bushings here and there, the rest of the suspension is stock. Will I notice any improvement? How long are original stock springs good for?
