Thank you....I don't even see it on the exploded view...

Thanks, and also thanks to Capt. for the explanations on the first page. Just curious as all the setup sheets I see are matched that way (narrow with 521, wide with 521-01) and wondering if there's something you guys know that I don't! Cheers,

521-01 arms come with the SP2. That was the first car with the wide hangers. 521 arms came on the SP, which had narrow hangers. UM566 rears from the WC car are the same as 521 rears. (As are LA272 rears)

Just to confirm
The the 521 and the 521-01 arms are exactly the same except for the 521 have 2 holes for the shock mounting and the 521-01 have a single hole that is between where the 2 holes would be.

other then that there exactly the same correct?

How are they different than ones already produced? How much does it weigh compared to the stock piece?

I'v never had an issue with the factory front hanger on either the rb5 or rb6.

Looks quality but I think it would lead to more bent or broken parts
