It will be smoother and reduce driveline loss. Everybody uses them for stock racing here although the entire field is B5M's. They will do as they claim but be careful and keep them lubricated or you will replacing the pucks often

Pucks work but as stated they need more attention than the stock stuff. The reduction in rotating mass is a good one, I also think it is worth it

What specifically needs lubrication and what to use? grease? Dif lube?

Thanks.

Black grease on the pucks, but really never had to even replace my pucks after an entire season. A few have had issues but none around here!

I am considering attempting to drill a hole down through the shock tower on either side to be able to slide a wrench down it, but I'm not sure there's enough material on the shock tower to avoid weakening it too much.

Just wanted to give a quick update on this if anyone is interested...I shimmed the rear shock tower 3mm off the rear bulkhead and can now access the ballstuds with a 2mm hex wrench. I did like the Yaiba rear bulkhead, but can't seem to find it available in the USA anywhere.
