A: Designed strictly for straight-line racing applications, 90/10 shocks will let your vehicle’s front end rise quickly and then slowly settle back down. While they deliver excellent weight transfer and better traction at the strip, they’re not safe for street driving. On the road, 90/10 shocks can adversely affect your vehicle’s alignment and handling, making it difficult to control on bumpy surfaces and in corners.
