Outer Limits 4x4 Board

A friend has just lunched a CV. It's an IFS 100s with a pair of ARBs.
Q1 - Is there a recommended upgrade CV? I have heard of Longfield but have also heard of accelerated wear issues with these.
Q2 - Should he even go down this road? Do the ARBs support the CW&P enough or would he be better off leaving the fail point in the CVs?

cheers

its good to have the front arb for strength of carrier to support crownwheel, and prevent failures, and solid pinion spacer as well, for the final touch, but if he leaves the front blue button out, he shouldnt have to much trouble with cv's.

If he does need to put it in, it should be with light throttle, and wheels straight .
