I would love one, but only 150 UK bound.
No wonder Mountune have announced a gearbox upgrade:
https://www.mountunestore.com/collec...stage1-gearbox
Based around standard gears and internal parts that feature shot-peening for additional strength, in addition, every bearing is upgraded to a more reliable unit that features a steel race, rather than the OE plastic equivalent.
To further improve the mountune Stage 1 gearbox's strength and to help improve drivability and enhance traction further, a Quaife ATB differential is also fitted as part of the upgrade.
Features:
• Shot-peened and super-finished gears and crown wheel
• Uprated bearings throughout
• Quaife ATB differential
• Rated to 500bhp / 600Nm
So maybe it's not the AWD or RDU that's the weak point, but the gearbox itself?
