No doubt the right grease will help the CV life over the long term or perhaps in racing involving hours of circulating, however virtually any grease should do the job over six short laps. Having said that, the next assembly will have the best grease for good measure.
Yes it is the cage that breaks all the time and once that happens, asta la vista baby.It's cactus fktus. That's latin for, it's had the dick.
I forgot to say before that to minimise weight, we are using the 2 litre CVs and shafts.
Kevin, I think you're on to the money.I was chatting with another racer and they went further than changing rebound settings, they changed from Koni Yellows to a local custom make of dampers and the problem has disappeared. Something about the logarithmic response of the Koni in the rebound phase contribuitng to the shock in the CV components during kerb hopping that knackers them.
I our case we like the Konis as the handling of the car is brilliant so I dont want to mess with that. I will however consider fabricating a Rotorflex coupling conversion in the half shafts to absorb the shock. With the addition of the Redline grease as well, that should do it I think.
