ATV Cup Car box, I need to measure pre-load on the diff tomorrow.
I believe this is ex-JBM/ Frode box so possibly they can shed more light on it's history. Selects all gears fine, and seems to clunk less than my gripper (annoyingly!).
I'd like £650 (basically £400 for an LSD installed and ready to go).
If this is going to be transported by me I will drain the box oil (can save this if you want)
Cheers

Collection Jct 12 M40 or BVF this coming weekend.
Sold pending payment.
did you ever get round to measuring the pre load on the diff ?..
just out curiosity wondering what it was set too .
Yup, this was very low I think due to non-diff oil being used at some point.
Normally cup car diffs ran between 80-110lbft I believe, I run about 90lbft on mine.
on the inside of the box i have build by JP engineering i think it was who fitted the diff must have written numbers on the inside of the box ..
.77 i think or 0.77 im sure..
would this be .77mm shim possibly ? .
How would u go about checking the preload? I bought a cup car lsd and had it put into my g40 box. No have no idea what the preload is

you need the diff out of the box to check it really. I think I might have put the procedure I use in one of my posts in the transmission faq section
