Wheel adapters specs

[JesterMX6]

I'm thinking its time to pick up some wheel adapters, at least for the front. Give me more wheel options so i can find proper fitting fronts.

What does everyone use around here?

My options, from what I can tell, are as follows:

Hubcentric to vehicle only - I feel like this will cause shimmy
Hubcentric to vehicle and wheel centric to wheel - this will be the most solid but also requires i use specific hub bore for the japanese spec wheels.

then from there I was thinking of just going 15mm for thickness (can always add spacers later). 12x1.5 mm for studs.

what center bore should i select for the widest variety of 5x114.3 wheels?

right now i'm looking at motorsport-tech.com but if anyone has a better option i'm all ears.

Ezaccessory.com, that's what I have, very cheap and 3 years with 0 issue.

My 25mm spacers aren't centric to anything lol. They don't shimmy at all. Except for my bent front rim that I still drive on.

i had non-hubcentric adapters on my e34 at one point and it had uncontrollable shimmy. thats why i'm being extra careful here

Mine are hubcentric and wheelcentric I believe (h&r bolt ons). But I run Style 5 and Style 42 wheels which have a different sized hole anyway. My wheels come off after every race though and I'm weird and retorque my fronts every time I change rears at the track. According to the Turner site on some non-centric spacers "These spacers are not for driving on. They lack the hubcentric lip that BMW wheels are designed to work with. Driving on studs alone will lead to a failure."
