VSLD-LSD Upgrade

I'm happy with them, course it took 2 1/2 months to finally get it right but hopefully your installer will be more competent. The traction with an LSD is just amazing compared to an open diff (I have base model). The acceleration is VERY obvious with the 4.08 gears.

However, I agree the hookup with an LSD is significantly better. Still haven't taken the plunge. I spend so much time fixing other Nissans all day I never have time to do anything but basic maintenance to mine.

Mileage is achieved through the mods listed and ignition timing adjusted by a few degrees advance on base.
