Optimize your Mk5 - Mk6 Golf/Jetta or MK2 Audi TT with this unit. The 02Q transmission is far stronger than the previous 02M 6-speed (used in Mk4 generation). However, strength isn't GRIP. Improving that requires a limited slip differential. There is simply no greater value available for street usage.
These diffs use helical-cut gears for civilized torque distribution and maintenance-free durability. ARP bolt kit and factory bearings are included. Availability is limited.
