Having issue with a bit of vibration at highway speeds 65-75mph, new Toyo tires, new OEM rotors, akebono pads, front tires have been re balanced, 4 wheel alignment done. Does not shack when hitting brakes, drivers tie rod end new, passenger side upper control has small crack in bushing.
Any help would be appreciated. Thanks

Spacers? I had a vibration at the same speed and it turned out my spacers in the back were causing it. That and I had cupped front tires.
Replaced front tires and shaking mostly went away, but once I took the spacers off it all went away completely. Never going to put them back on.
They were 5mm btw

Shaking from the steering wheel = front wheels
Shaking from the seat/floor = rear wheels

could be control arm bushings too.

No spacers on car, going to replace upper control arm passenger side this weekend. Will check drive shaft flex discs and bearing car has 112,000 Kms

I think I figured it out, brought my car in to rebalance tires again, and tech good friend of mine says drivers side wheel has a high spot in it, he says its common on Mercedes factory wheels. Fix 60.00 Canadian, will keep everyone in the loop if it fixes it

I was going to buy the racing brake rotors, but I saw a few issues with them on YouTube, they breaking apart or seperating, anyone know where else to get light weight rotors from?
