22RPD Subframe Design features:
- Completely redesigned and optimized subframe
- Full 7-gauge laser cut steel construction
- 1000+ TQ launch capacity with 2:1 Safety factor
- Retains Factory control arms, Trailing arms, and sway bars
- Improved suspension geometry, including 8.4mm of roll center correction for lowered cars
- Input shaft lowered 3/8" to easily fit a 3.5"+ diameter driveshaft
- Fully powder-coated finish
- Weighs 11.3kg (24.9lb) compared to the OEM subframe at 9.8kg (21.6lb)
What does all of that mean? More reliability, more track time, faster corner exit, higher grip threshold, faster launch, and much more fun.
Benefits of the Ford 8.8 “Supercase” differential:
· Used differentials can be found for as little as 250$
· Lots of ratio options: Aftermarket ratios begin at 3.08 and go to 5.10 in ~0.2:1 increments.
· Comparable weight to the 188 diff (The aluminum case option is ~75lbs)
· Cheap replacement carriers (New LSD carriers run $177+)
· Brand new OEM clutch type differentials can be found for the $800 range.
Common factory differentials include:
- 3.73:1 Torsen Type
- 3.15:1 standard Clutch type
- 3.55:1 Standard Clutch type
· Aftermarket adjustable camber arms are required for this install (SPC, Turner, Bimmerworld, Etc.) The factory arms with sheet metal construction are too large at the inner mount.
· Adjustable sway bar end-links are recommended and may be required depending on the ride height/sway bar selection.
· It is strongly recommended to have rear subframe/chassis reinforcement plates installed (OEM or equivalent). This kit uses solid mounting for the subframe and the diff which will transfer more NVH to the chassis.
All kits include a complete installation manual, installation hardware package, Driveshaft specification sheet, and your choice of subframe bushings.
