So far I found they need to be 5x120 bolt pattern / 72.5mm center bore
and 14 x 1.25mm bolts

72.6mm center bore according to H&R. The Ubercentric ones from Amazon are also 72.6mm.

The stock lug bolts are 27mm shank length, so the new bolts have to be 27mm + whatever the spacer thickness is. It doesn't have to be exact because there is quite a bit of clearance before the bolt bottoms out so if you do a 12mm and 15mm spacers, you could use a 40mm shank bolt no problem.

Yeah that would work too...really there's no right or wrong answer here I don't think, just personal preference.

To me it does, makes the back end looks weird in proportion to the front. I like this weird balance of almost looking OEM but also aggressive, like you can't really tell if it came like that from the factory or if it was modified.

Thanks for all the work HX_Guy. I'm running 12/15 and will swap to 15/12 based on your research. I agree that 15 is a bit too wide in the rear.

It's the angle, honestly that does not look like an 18mm spacer in the rear.

18mm is going to look weird...I think 15mm looks weird and we've had two other member say the same thing. Go with 12 if you want it to look aggressive, you'll like it.

was able to play around with a 14mm Styrofoam flat sheet and kind of see what you mean on the back....it's like the rear is already sticking out a bit...

So I think 12mm should be ok on the back....
Now I wonder if I should put 15 or 12 on the front

What did you end up with?

Still have the 15mm front and 12mm back right now but I just got the 10mm in the mail today and will put them on one side tomorrow to do 12mm front and 10mm rear for a few days and see which I like more.

Haha, you already saw what the 12mm front and 10mm back look like in the pictures. I'm going to run them for a few days and see how I feel about it.

ah you are right... just looked at it.... I think I'm going 12mm all around... I like the 12F front and 10R is ok but I think I would like 12R better

wish me luck

You could always order just one set of 12mm and put one of the spacers on the front and one on the back on just one side of the car and see how you like it.

Haha I didn't mean drive around, I meant to visually see how it looks. I'm sure if you took a spin around the block it wouldn't harm anything but I wouldn't leave it like that long term I don't think.

Took all the spacers off earlier this morning to send them back, between improper fit and some vibration issues, I've decided I'm going to go with a trusted brand like H&R over these Ubercentric.

I decided against the 15mm front and 12mm rear...will do 12mm front and 10mm rear, but I am thinking maybe 13mm front would be a good compromise. Definitely 10mm rear though.

BTW the car looks terrible now without any spacers...just looks so weak, I don't know, looks so off. Spacers are definitely a must, or aftermarket wheels that are either wider and/or better offset than stock.

Let us know please, if the H&R really slip on...slip off without fouling the dust cap or having to "force it a bit" to make it all work. This spacer issue for mainly curb appeal is not worth it if the machine work on fitment is not right.

Worst case I guess, is someone could take one that is "close" but not right, have a competent machine shop mic it, and turn it to really fit proper.
