Delrin is normally considered a high performance nylon derivative. They are different, but both are a step up from poly regardless IMO.

Thank you!

Pete doesn't autoross much but does have a bunch of track time experience etc with pretty sticky tires.
My point is he has experience with his products.
I think he may now have the greasable or he suggests customers use Firmfeel's.

Seeing that your in Sidney, see what is available for Valiants. The SPAX shocks on my car were intended for Aus - Valiants. There was a larger market for saloon racing in your county and new Zealand than other parts of the world. Not everything transfers over but many things only need minor rework. The bushings for the rear shocks are slighlty different ID. Easily modified to fit the US and US export A-bodies. Wouldnt surprise me if the LCA bushings are the same.

Delrin LCA, and rod end struts are least compliant combination for sure, and with a rod end strut, the effective arc length is usually shortened, aggravating any needed compliance.
Two things come to mind that might offset the compliance direction of that combination, the user does not have reinforced LCA ( , don't get me started) and the on track suspension sees limited vertical movement, either mainly by smooth track surface, choice of Swaybar and/or TB, etc..

Mattax ,
Thanks . I run a 68 b body . Even with some road race stuff here it is a quite small market .
JCC , i think you are on it . There must be some give to combine vertical lca with a fixed strut rod through an arc . For mine , street/strip , it might be an "either or" situation . Heim strut rod and poly/rubber lca bush or delrin lca bush and poly/rubber strut bush . ?
