Hi all, can anybody tell me the diffrence between the standard 355 gearbox and 355 challenge gearbox (ratio). Is there a diffrence at every single gear or the overall ratio. Thanks
I looked through the Ricambri parts lists and found a couple of spacers that are different in the 95 vs 95 CH. None of the 96-99 gearbox stuff looked different. A handful of CH cars were found to have Mondial 328T drop gears (higher multiplier ratio) at teardown and after leaving the race circuits.
