One-wheel peeling. Rear bar too stiff or fried diff?

Stock VLSD I assume?

If so, fluid within sealed vlsd is prone to overheat. Once that happens, it’ll behave like an open diff.

Rusty has a diff cooler and diff temp gauge, he mentioned elevated diff fluid temperature even just driving around town.

Yup stock diff. Wasn’t expecting to get any overheating on a short autocross run but I guess it’s doable!

Install an OS Giken with a diff cooler or a Wavetrac. Problem solved. The OS Giken is extremely good. Made a big difference on the Tail of the Dragon.

Your VLSD is done.

The VLSD uses silicone fluid to operate. The fluid breaks down over time. But it breaks down quicker with heat. The more high heat cycles it goes through. The faster it breaks down. The more it breaks down. The more heat it creates. It's a vicious cycle.

Stock fluid, too? Or are you running Motul or Redline or something?

The stock fluid boils almost immediately if the car is already warmed up. The VLSD is pretty much worthless because you don't need it for casual driving and it can't handle hard driving you actually need it for

That's what I run. It helps some. Just delays the inevitable a bit longer.

I’m thinking my diff might just be ‘tired’ due to the track use from its past life (prev owner)

SC’d, track use from previous owner, track use by current owner. Time for new diff mate

Mine was doing the one wheel peeler at 8k miles. The VLSD is just chit.
