Again, I am not saying the bolt on spacer is unsafe, I am saying that it doesn't seem anymore safe than a 6mm spacer. Trust me I bought open ended lugs and will test fit things, if it seems sketchy I won't do it, but I have no reason to think it will be the case.

As for the bolt on spacer it is a bit concerning that you would have an opinion with so much certainty but don't really understand how they work.

How did you come to that conclusion?

s2000Junky

If you have a proper amount of thread turns for the nut by utilizing a studded spacer, then how is shorting your stock studs by 6mm adding that spacer offering you the same safety?

bgoetz

Because, you didn't realize that some wheels have plenty of room to accommodate the OEM stud in recesses behind them (i.e RPF1s) OR people cut the OEM stud flush.

s2000Junky

Really? How did you gather that from what I said re posted bellow?

"And finally the problem with a 10mm spacer with integrated studs is that the studs and nut protrudes well beyond the face of the spacer and that means it wont mate to the wheel. Typically 15mm is the slimmest design ive seen that will fit into the back recess of the wheel, but that's wheel dependent, usually 20mm is the min sure deal."

bgoetz

the bolt on spacer has special nuts that sit flush to the spacer itself, they are conical and use a special tool. These nuts cannot be any thicker than the thickness of the spacer itself, which is why 10mm is the thinnest you will find. So on a 10mm spacer that nut cannot be thicker than 10mm, it actually has to be less to taper into the spacer. So all that is holding that spacer, with the extended lugs onto your wheel is 5 of these aluminum nuts which are less than 10mm thick. Sure you bolt the wheel to extended lugs, but what keeps the spacer itself from pulling out?

bgoetz

Look I am not going to get into a pissing match with you. You clearly didn't realize that RPF1s have a ton of space to accommodate or that you can cut the studs down.

bgoetz

This is a conversion spacer, but is the same thing and you can clearly see what I am talking about. It does appear that the nut goes the entire thickness so a 10mm spacer would have a 10mm nut.

The one in this listing clearly has conical nuts so it would possibly be less than 10mm (yes I relize it isn't for an S2000, I was too lazy to find one)

If they make a slim 10mm design as you say that the nuts are reduced in size to sit flush, and or any excess on the studs could be cut down to accommodate the back of the wheel without compromising thread turns on the nut, then I'm all for it. I've never seen one, but that doesn't mean they don't exist.

s2000Junky

I see a space for a conical nut, but no slim nuts.

The first link doesn't work btw.
