A WRX with a big trunk audio install or a rally-style spare and tool kit can settle at the rear and look tail-heavy. The ADF 3/8" Rear Leveling Spacer lifts the back 3/8" using one machined HDPE spacer under each rear strut top. It is offered for the 2002-2007 WRX and STI and for 2008-2026 WRX and STI models. HDPE is stable from -130 F to 250 F, so it shrugs off Calgary winters and summer heat alike. On these cars it is a subtle change that corrects rake without touching springs or dampers.
