From Super pro when I did a warranty claim on the previous duroball “The holes themselves are there to take up any shrinkage during the curation process in the final bushing assembly. Initially these were then ‘filled’ by that small pour of additional poly. Initially tested to see if the assembly benefitted in anyway from filling those holes (it did not) it ended up being retained as the team apparently felt it made the assembly look better. At some stage they reversed course on that as it let us remove an unnecessary step from production that had no bearing on the performance of the finished product.”
Opposite side with the crack
This is the previous revision of the bushing I had swapped out. Had these on for about 3ish years I think.
If I’m able to get a warranty claim on the current bushings I may go the route on what Dallas said and have the holes filled with poly.

So did an autocross event today, went home and swapped to my DD set of wheels. I noticed one of my super pro lower control arm bushing is pretty much destroyed. I swapped a previous set of lower control arm super pro bushings about 6 months ago since they were cracked and bulging out. Pretty disappointed with the duroball since it only lasted at most 6 months(not sure when it failed), probably can handle DD duty but obviously it can’t handle autocross. Wonder if this aided in my last set of tires odd inner tire wear.
Anywho anyone have some recommended bushings for the front control arm rear bushing?

The white line setup for that is a no brainer.
They also have a low NVH option now-
Send me a DM, I can hook any forum members up with a lot of drop shipped parts.

Has anyone gone from poly to metal or vice versa for the lower control arm rear(the big one)bushings? I wonder how much of a difference it is going from poly to metal. I have no problems with a poly mount in that location in terms of nvh but worried metal may make it unbearable.

I think this may be the case. I gave a closer look at the opposite side of the car and it has started to do the same. It cracked right to the bigger hole. The previous revision of this bushing had the holes filled with poly. Text below is an email explaining the holes and them being filled. They also explain why they don’t fill the holes anymore with poly since they didn’t see any benefit for it. But me pretty much testing both versions, the one with poly filling the holes is more durable.

ralliart versions are like oem, as they use sphericals in the same positions, just encased in harder rubber and they do not have any reliefs in the rubber like big front bushes do. Outer and inner bush for the lower rear arm is the same as OEM IIRC, as the rubber layer there is very small. Shock mount is harder tho..

Wish this whole set was still available. Looks like it's discontinued

They are designed for the Group N class to add durability. Maybe the rules for Group N are more strict for what can be changed, I have the rear crossmember bushing and it is holding up well, and will be doing the engine mount inserts once I move and have space for a press. I think I would rather have these than poly tho.
