This version is meant for competition use. It is triple braced at the hub for added strength, it uses different spring lengths than the offroad version, and it is optimized to be run at 1-1.5" over OEM height (approximately 27.5-28" ground to arch height on 08-14 WRX). OEM Style hybrid mounts are recommended.

This version is meant for offroad and crawling. Perfectly suited for street and daily driving, but optimized for offroad adventures. Optimal ride height is 2" over OEM height. This version uses longer springs without helper springs and the main springs can be customized to suit the additional weight from gear, metal bumpers, spare tire racks, roof racks, etc. On 08+ you will need to run subframe spacers to ensure proper rear alignment over 1.5". Camber plates are recommended.
