Kaaz if you're prepared to invest $$$ in it, otherwise a spool. Mini or Full.

The stock LSD Centre isn't much to write home about. You can have them rebuilt, but the cones wear pretty damn fast.

Is it an auto or manual diff? If auto, it has the 3.9 CW+P, you can go to pintara 4.11 gears,

if it's a manual, you can go to either R31 3.89, or piny 4.11.

You have to have it all apart to do a centre, so may as well do it once.

There's VL Turbos running 8's on slicks and 28 spline axles, so for a big power 30DET... personally i'd run a full spool and OEM axles (Moser billet axles aren't too expensive) and 4.11's depending on the gearbox. You're setup may like 3.89's.

Just my opinion. Hope that helps.

Just an FYI... OEM axles mean the stock ones. OEM = original equipment manufacturer. Your reply sounded like you thought it might have been a brand or type.

If you're on you're third diff... maybe a set of moser axles would be the go for you. Get a 31 spline spool and matching set of mosers, with a 4.11 CW+P, would be pretty much unbreakable.

And you'll be getting a tailshaft made for the 25 box, so may as well get a bulletproof shaft done as well.

VL LSD is still cone type, which, even when rebuilt, will wear out pretty quick, and you're back to square one. Been there done it. Not worth the trouble.

My recommendation is still a spool, stock axles, and gear ratio to match.... KAAZ LSD/Harrop true-tracs's are at least $1200+, probably another $500 to fit... plus all the other consumables like bearings and seals, and a CW+P if you wish to change that too.

You've got a $2500 diff by that point. Mini spool for $75, $100 on bearings and seals, leave current CW+P and have it all assemble and cleaned up and be under $1k

I ran this exact setup in my R31 track car and it was faultless..... came out and was sold when I transferred my running gear to a HR31 coupe and is still running great.

Up to you now where you want to spend the $$$

Unsure if pintaras were release in NZ, but you can buy the CW+P's cheap enough on ebay that even if you have to have them lapped and cleaned up, they're still worthwhile. Seen them for around $200 + post.
