Group ND Proposal
The final drive assembly is free save that:
Any replacement assembly cannot widen the wheel drive flange to flange width more than 40mm.
The body work including pick up points for the final drive, remains unchanged.
Justification and Rationale
Being able to alter the final drive assembly allows competitors to utilize readily available and relatively lower cost components, eg using the common HILUX diff for which there are a plethora or race-suitable ratios and LSD or locking units.
MODELS with particularly fragile final drives can be upgraded to better manage costs.
Note: ND vehicle can be RWD live axle, RWD IRS, AWD, FWD.
