I think youd be better of with an 8.5, 9.5 or 10.5
Yes i use a 4.5 in my vintage but its a bit special and has tensioners on the belts which aides it in handling the power. Handling well i made tenth in the Maritime series championship so shows that newer doesnt always mean better. Slipper yes youll need to upgrade but wouldnt parts from the new 4wd fit seeing as they have basically taken the xx4 drivetrain and upgraded it?
