Mooresport Rear Subframe - Subaru WRX / STi 2002-2007 / Impreza 1993-2007

MFG: MSISUB05-28-002

A major problem when lowering a vehicle is that the factory wheel geometry and roll centers change. Mooresport was the first company outside of Prodrive to offer a commercially available alternative rear subframe suited specifically for the motorsport marketplace and professional teams.

A change in the vehicles ride height can drastically affect the path a wheel will take through the range of suspension travel. Camber and toe can vary to point that the car goes from over-steer, to under-steer characteristics in a mere 3mm of wheel travel.

The MooreSport subframe is manufactured of ultra-light 4130 chromoly steel tubing using the latest technology in CNC tube cutting as well as mandrel bending. Each unit is assembled in a heavy duty jig, and is then verified in a separate jig after stress relief is completed over a 24-hour cool down period.

A CNC machined T6-6061 billet aluminum differential mount with FLURO stainless steel motorsport bearings allows the removal of the differential separately from the frame -- a major consideration for racers who require frequent rear-end changes.

Each subframe is bead blasted, then coated with a high grade flexible epoxy primer. Finish powder coating is baked on at low temperatures to avoid distortion of the frame.

The MooreSport subframe is lighter than the factory assembly by 40%, while increasing the rigidity and consistency of the rear suspension system beyond what is commonly scene in the North American marketplace. Average weight (depending on options) is under 16 lbs, compared the OEM unit at 30 pounds.

PLEASE NOTE THAT DEPENDING YEAR / MODEL FUEL TANKS ON OEM APPLICATIONS, SMALL INDENTATIONS MAY BE REQUIRED IN THE FUEL TANK. THE REMOVAL OF THE SPARE WHEEL BRACKET ON THE UNDERSIDE MAY BE REQUIRED AS WELL. PLEASE INQUIRE WITH OUR TECHNICAL SUPPORT FOR MORE INFORMATION. THIS INSTALLATION SHOULD ONLY BE DONE BY TRAINED PROFESSIONALS AND IS NOT MEANT FOR DIY ENTHUSIASTS. A COMPLETE 4-WHEEL ALIGNMENT WILL ALSO BE REQUIRED.
