Tuner Motorsport (TMS) 10mm flat spacer fitment problems

[BANKAIm3]

Anyone here have experience with wheel spacers from Turner Motorsport?

I am trying to use their 10mm flat spacer with their hub extenders and the spacer just will not fit onto the hub.

I can get the spacer past the extender but once the spacer has to past that, it will not go over the hub. My hubs are pretty new since I changed my wheel bearings recently and I live in Southern California so there isn't much rain and definitely no salt on the roads. Even so, I used a wire brush to clean up any rust, a scotch brite pad and even attempted to sand them down a bit. Still no luck.

Are clearances that tight on these? My car was cold when I did this too so it isn't like the hub has expanded from heat. I didn't want to hammer them because I don't think I'll ever be able to take them off if I did.

My old 8mm tms flat spacers mount flush to the rotor face. Have you tried contacting them about this?

I contacted them and the problem is my aftermarket SKF wheel hubs. The hub diameter is off enough that these TMS spacers won't fit. =( They are now for sale to someone who still has Genuine BMW wheel hubs, or at least aftermarket hubs with a closer to a 72.56 hub diameter.

I guess it goes to show the tight tolerances that Turner Motorsport manufactures their products...

Update.

It was a very snug fit, but I was able to get them to fit by tapping them with a mallet. I had a spare wheel hub laying around of the same make (SKF) and it fit on this one so I attempted to get them to fit on my car again. What made it a little difficult is because of the tight tolerances TMS uses on their spacers. The extended studs I have aren't centered in the holes, so it was impossible to wiggle it on. The spare hub I had laying around does not have stud installed so it went on there with having to tap it with a mallet.
