Happened upon a set of adjustable Racing Beat end links that use polyurethane bushings instead of the stock ball joint.
These will be going on a non-bilstein NB2, with a RB front sway.

I’ve been doing some reading and it seems that they might be a waste. The polyurethane bushings are more of an upgrade for NAs, which didn’t use the same end link system as NBs do. Will these really do anything to help? This car will be a DD, but I was looking to stiffen things up a bit for an occasional AutoX.

I’m not against heim jointed links, I just got a great deal on a polyurethane set.

Waste, for a street car I’d suggest stock links even over spherical.
