delrin bushings for s550?

[Anviltester]

does anyone know of a company that makes control arm bushings front and rear for a 2018? all I can find are spherical and they are not legal in the class we will be running

I have seen urethane bushings for the S550 but not Delrin, but since I have an S197 I haven't really looked for them.

The bushings that aren't already sphericals are all multi - angle and would bind up if delrin. What class/org has this requirement?

scca for T2 class. Rules say allowed to replace oem upper and lower control arm bushings with poly or delrin bushings. not allowed sphericals other than where the toe link in the rear attaches. It's my 1st s550 race build so learning as I go but learning fast. will have multiple subframes (front and rear) out later this week (have multiple donor cars) to physically see how it all works. car will finish strip this week and cage go in early next week. just trying to eliminate the rubber stuff. maybe I need to design a delrin type spherical (I have a cnc machine shop) as that may stretch the rules lol.

Good news is the S550 lateral arms in front are already spherical + ball joint. Rear lower bushings that take the lateral load is also a sealed sphericals. The rubber is only in the rear upper link, toe link mount, and the longitudinal plane (trailing arms in front, forward bushing in the rear). They are not bad to leave rubber, as it helps with impact compliance on curbs and such. The chassis is still fast like that.

well that would explain why I can't find delrin kits for it lol. we are changing to adjustable toe links w/ spherical (allowed) and the lower toe spherical in the arm so that eliminates those. ill have to look at the other to see if leaving them alone or changing to poly or delrin is a better solution. joys of fea analysis software and 3d scanners lol.
