running a 7.5mm customer spacer with hubcentric lip?

[charlescho]

I am in the process of making some custom spacers,

7.5mm for the fronts and 11mm for the rears.

I was told by a couple vendors that 7.5mm is too thin to make a hubcentric lip, but have also been told that it is okay...

I am kind of confused as to why some say it is okay and some say it is unsafe....can someone shed the light for me please?

thanks :p

You don't really need a hubcentric lip on any spacer under 8mm. You can do it, but there's almost no need and it does get a bit sketchy. The worst that'll happen is the lip will bust off while mounting a wheel.

yeah, e30rob said its not safe to make a hubcentric lip on a 7.5mm and I believe him a whole lot more than some of the other guys that are making wheel spacers. its unfortunate that rob is not making any more spacers :(

If your 5 Lug you can use hub extenders. I use these on my 5 lug swap with 5mm spacers.

the reason you can't get fully hubcentric (to the wheel and the car) spacers in widths that narrow is due to the flange on the front hub of the car, which usually protrudes around 8-10mm from the mounting surface.

to machine a similar type flange on the spacer itself, it must clear the flange on the hub of the car first. and beyond just clearing the flange, there has to be enough meat for it to be strong enough to safely work.

i'm an adaptec dealer, and the skinniest fully hubcentric spacer we offer is 13mm. hope that explanation helps.
