thats is the same question I did to Quaife , what is the life of the gearbox
they dont have any information about that because the dont needed to rebuild any of those gearbox at the moment , using it on a complette rally championchip and enduraces championchips
at the moment I been two times on a tracks and some traveling ( arround 1700 miles on a public roads ) with it and no differences escept the gearbox noise is lower than before
also I just fit an oil cooler with filter to the gearbox so Ihope to get a long life of it.
I am very happy with the gearbox , really happy and I know if in the future I will need to sell it , it will be very easy because the price , it is the most universal and cheapest race gearbox I found.
ofcourse if you want to buy one of those gearbox there ,you will need to pay close to the double than me, here in Europe , I paid 6000 eur but in Dollars will be arround 10000 USD with shipping cost and maybe plus Customs taxes , so for me it is not expensive but yes for you. I Understand.
here we have some parts and tools and there you have others, for example if I want to do a copy of a rear knukle like you`re saying here it will be expensive very expensive so....I prefer to see if is possible to weld the rear subframe
and also wellding the rear sub with the chassis , it will be stronger than now noo???
mine don`t have any crack at the moment ans also mines look like it have a reinforcement from factory because it have a double wall where supouse it tend to crack...but I am not sure if it is normal.
the idea of use a bushings on the differential is to reduce the noise and vibrations inside the cockpit
I am using the car every weekend and only 3 or 4 time inside the tracks.
next year I am planing to do the hole time attack competition here in Spain but I want to be competitive jejeje but maybe the car is not the problem jajajajaja
