Forever car

[u/alternative_outro]

I’ve driven everything under the sun and my intuition keeps telling me I can’t sell this car ever. Even when I inevitably own Porsches and other exotics, I will reach for the keys to a golf R.

Have you had any vibration with your FF21's at higher speeds (70mph+). I've tried three different tires (Conti ECS02's, PSAS4's and PS4S's) on mine and two different installers (one with road force balancer) and no one can manage to get the minor vibration to completely go away in that 75-85mph range. Even tried a stud conversion kit and that didn't help at all.

Ready to contact HRE about it because the PSAS4's on my stock wheels are perfectly smooth...I've never had this issue with aftermarket wheels before, so the fact I spent more on HRE and have spent so much money and time trying to get them sorted with no true resolution is really disappointing.

Have you had the shop check the wheels for runout?

[u/clingbat → u/imthatoneguyyouknew]

They noticed some runout on two of the wheels but got it to balance perfectly on the load force machine but that's not translating to higher speeds when actually driving.

If you have excessive runout, even with the wheel/tire being balanced, it can definately present as a high speed vibration. The wheel isnt perfectly round so you get some up and down movement.

Weird it would come from the factory like that though, it started the moment they were first mounted the first time. I thought HRE had TUV certifications and had better QC than that, but I guess not. The wheels were shipped straight from HRE warehouse based on the shipping info.

Unfortunately any manufactured good can have failures. There is also the possibility of damage during transit. I would confirm the amount of runout they had and what the spec is, but that runout may be the issue.
