Does anyone else have the SuperPro Duroball busing [DURO3441K] for their EVO X? Please let me know if yours has massive holes drilled in the polyurethane. The pictures show it's solid.
I'm concerned it will give too much flexibility, the whole reason switching to these is to reduce that.

Yea, that was an "update" they did to save money, supposedly it doesn't effect performance, but an IX with them split them at the holes soo.... Go look through the 2024 STU thread.

That's just great... Thanks for the info though, I appreciate it.
Do you know if the non-offset version [DURO3439K] has the holes too? I may exchange it, that minimal extra caster probably doesn't worth it.
What about the rear ones [DURO3737K] and [DURO3725K], I have ordered those too, waiting for them to ship. Pictures show solid but I can't rely on that apparently.

My mistake it wasn't the STU thread, it was the 2024 Projects thread..

Wow, thanks RobbieOh for finding the thread! I'm working with MAPerformance to see if the non-offset version has holes, I may try to replace them since I autocross and track the car regularly.
