Recently installed the Cobb RMM and never really drove it at any speed. Have a couple hundred miles on it but top speed was probably 65/70. I then got Michelin pilot sports as3 installed by a tire guy that has done all my tires. He said most of the wheels didn't even need weights as they balanced out perfectly compared to the stock tires that had strips of weight. (possibly were high speed balanced from factory? Not sure if that's makes a huge difference)
First time I got to about 75-80 a very noticeable wheel shake started. But the car tracked perfectly straight. I slowed down a bit and it was smooth. Happened again for a short while at the above speed then stopped. I thought it was just the road and the higher psi I was running.
Since then it's been occasional. Yesterday I got to that speed and it came back, different road. So last night I played around with all speeds on the same section of road. And I couldn't reproduce it.
Other than the obvious of poorly balanced wheels, but I get no shake at any other speed and its occasional.
Other forums for other vehicles suggested an issue with the RMM.
Thoughts?
