I am now an Authorized Dealer for VMR!!!!

[BCS_ZHP]

Ordered a pair of 19 x 8.5 et35 matte black VMR 710s on Wed, they shipped yesterday, supposed to arrive next week. These will go on the front of Preston's 335 as he's running 19 x 9.5 et45 with a 15mm spacer and 245/35 tires, had vibration above 60 mph. Tried rebalancing twice, even Road Force balancing, tried new tires, still a slight vibration but now not until 70 & above. And then swapped these wheels/tires to the back of an e46 (perfect size for that) and absolutely no vibration all the way up to 80. And no front end vibration on the 335 with stock wheels/tires, so the front suspension appears fine. My theory (and hope I'm right) is that the balancing machine doesn't have a way to account for that much spacer, the wheel/tire assembly can be balanced fine on the machine but when it gets mounted with a 15mm spacer we're changing the dynamics enough to cause a slight unbalance condition. Also by going to a wheel that's an inch thinner it enables more tire to be at or past the edge of the wheel and should aid in the ability to properly balance it.

If this works as planned, will have a perfect pair of slightly used VMRs for sale shortly, less than 10K miles on them. They fit the back of a non-M e46 perfectly (that's the size my son Brett runs on his ZHP, with 265/30 tires) or the front of a e46 M (that's the car we bought them from). Then you could buy the other pair from Ray and save some money on a whole set.

Update: it looks like the old fart's hypothesis was correct. 9.5" wide wheels with 15mm spacers were too much for the front of the e90 to handle. The swap to 8.5" wide with proper offset & no spacers eliminated the vibration at high speed, relatively speaking. Smooth at 70, I felt it very, very slightly at 80, but nowhere near what it was before, we're happy on this end. And damn those are good looking wheels! Thanks Ray!

How about 9.5 with no spacers ?

IDK, didn't have a set of 9.5 wide wheels with proper offset to try. And with 19x9.5 on the front, about the max tire size possible is 245/35/19 which is on the verge of a "stretch" fit. Any tire larger than that will hit the inner fender liner.
