Hi all

I was skimming through the Classic Motorsports site today and noticed a description of shimming an Alfa differential with VW flywheel shims. http://www.classicmotorsports.net/news.php?cat=3

The description is about 10% of the way down the page dated 2/20/07.

The description reads:
"We spent about an hour working on our limited slip differential at RML Automotive and we improved the “action” of the unit from just about nonexistant to having about 100 ft.-lbs. of breakaway force. We did this all for a whopping $2.
The trick was using a flywheel shim for an aircooled VW. We purchased several of these $2 shims in varying thicknesses and put them between two of the cross plates. We settled on a .36mm shim that gave us quite a bit of locking action. The friction plates looked fine, they just needed more pressure to work correctly. "

Has anyone on the BB tried this?
Regards

Simon

Hi Razzo rosso,

I have shimmed the LSD in my autocross Spider. To increase lockup, you can add two friction plates to the LSD, add shims, or a combination of both. Shim material can be purchased in sheet form and cut to size. Additional plates from used LSD's may be used or new ZF plates are available at alfaholics http://www.alfaholics.com/ for US $97 each.

Russ Neely, AROC competition chairman, wrote a nice description of the process. I think I posted this on the BB, and can be found by searching, or I can send you a copy.
