Gearbox YES had an appetite for them std only lasted a few launches but normally 2nd and mostly third that would get eaten

Got a quiafe big tooth box in the end, that lasted one year and then destroyed 5th without even giving it too much grief (was second hand when i got it) got it rebuilt by Bernie and was sold two years latter still going strong
(this is the box I used when I did my 2.99 so not as bad as everyone thinks from first to second )


Rear diff was also standard (again lol) just never seemed to have the time or money to uprate things that wouldnt break
