Building an RX7 LSD diff

[Hobbawobba]

Here's the single use crush washer, which maintains the tension on the bearings (new one on the right):

Yo. I have seen that a few places online sell a solid spacer/bush to use instead of the crush tube aye. Do you or anybody else on here have thoughts on solid vs crush at all? In particular with above average horsepower

[TOOL]

Solid just means you can do the pinion nut up “full tight”.

In theory, it’ll be buttoned up, so can’t have any slop.

Other parts of the diff, rear axles will more than likely fail first though.

PS S2 and earlier diffs have bigger teeth on the CW&P so are an upgrade for big power S3 cars.
