I've never run a Worlds car - both mine are original cars. The car with big belts however has NEVER had equal diffs like yours - I've always run it with 36 overdrive one way. The 'worlds' has some nice stuff but mostly it's a scant upgrade from the orignal car - more bling and bits you don't need than anything. The big belts are the best bit.

The overdriven front end really settles the car down - makes it easier to drive and plants the rear in loose conditions. I'd imagine the exact opposite - but the proof is in the driving.

Yeah I'm not a fan of the machined pistons - i've had them and lost them in my box somewhere - tried them and it's like going up 20wt all round so ditched them.
