I’m very new here, in the early stages of building up a SpecE30, and I’m looking for a clarification. The only reference I see to the rear upper shock mounting in the rules is:
18.104.22.168. Solid rear upper shock mounts are permitted.
Can someone tell me exactly what that means? Maybe a few examples of what’s permitted? It would seem that OEM would be allowed, and I would think that polyurethane is allowed by 22.214.171.124 (Suspension bushing material replacement is permitted). Are spherical bearings allowed? For example Turner Motorsports part# TSU9906SM1 ? I might consider it solid since there’s no flexibility built-in, but due to the bearing, it’s not exactly solid either…
