ZX5 still a good car, wouldn't worry about the ball diffs, build them correct and they will last the season. I've found the ZX6 is a step up from the ZX5, but being honest most people would realise the new car will be exactly that. Main difference (I've found) with the zx6 is the sharper slow corner turning, but overall the ZX5 is still a very competitive package.
The Zx6 uses ball diffs as well as standard and they work great.
