Excellent Coil Over

Purchased for my '95 Mustang GT. Easy install - although the instructions could be better - check out Maximum Motorsports coil-over instructions. Love the adjustability both height and Compression / Rebound.

Great coil-overs! Very nice pieces! The kit did come with the wrong torrington bearings but one call to QA1 and they sent the right one with no charge. Hard to beat all-in-one kit for the money.
