Installing spacers on wheels?

[Maluco]

By rolling, you take a bat or a pipe and push the thin metal on the inside of the fender lips up/out. I think you could run 20mm in the rear because you have higher rear arches and you won't be lowering the car that much. TMS sells both bolts and studs. The bolts are the stock style setup where you hold the rim up to the hub and slide the bolt through into the hub. Studs screw into the hub and stick out, and then you slide the rim over it. I'd recommend studs because you can mount the spacer on before you even put the rim on. With bolts, its really hard to line the space and the rim up to the hub and then slide the bolt through.

Gotcha!!!:)

The rims you have aren't made for E30's so the center bore is larger than the hub on the car. A hubcentric ring has a center bore the size of the hub on the car and an outter bore the size of the center bore of the rim, therefore it centers the rim on the hub.

Ok, I understand however you would think bolting the wheel to the car would be enough???

I called TMS and they don't sell the studs I would need for my application. They only sell 75mm and 90mm studs which would work if I used regular lugnuts allowing the tip of the studs to go through them and therefore protrude out of the lugnut. However, I am stuck on using my wheel locking lugnuts, which are closed ended. So I need to figure out how long of studs I need that would allow for me to still appropriately tighten my (closed ended) wheel locking lugnuts. And due to the difference in designs of bolts to studs, I don't imagine it's as simple as buying the equivilent length stud as is required with the bolt. Hope that was clear.

regarding the hubcentric rings, how would I know what size ring to buy?

They are 205/50-16 BFG G-Force Sports. They run slightly wide... nice tires for the money!

Also keep in mind that Carlos has wider tires (215), so he will be more likely to rub. With that in mind, plus the 2mm of less offset, I still recommend 15mm spacers.

I have an offset of 20mm after my spacers, and I'm not sure if I can fit 215s in there without rubbing.
I'm considdering getting a set of 15mm spacers (instead of my current 20mm) so I can run wider tires.

I have closed end nuts, 20mm and 75mm studs and it works fine.

The hub size of E30's is 57mm so you need to find out the center bore of your rims. Then call www.discounttiredirect.com and they can get you the size you need if you know the 2 diameters.

ok, so 15s!!! Ok, I am going to physically measure the gap the best I can.


TJ - "I have closed end nuts, 20mm and 75mm studs and it works fine."

Ok, so if I get 20mm I should be fine? But with 15mm the 75mm studs might possibly be to long for the closed end nuts, hunh? Also, wouldn't you have to factor in the offset of your wheels into that?

The offset of the rims doesn't alter the thickness of the hub of the rim so you don't have to factor that in. I think with closed end lugs and 15mm spacers they wouldn't tighten properly.

I meant factoring in the offset in regards to the fact that you have 20mm with 75mm and closed end nuts.

I guess the only way of really figuring it out at this point is to physically measure and get as close as possible....

I'm not sure what you mean. I think you are thinking the the offset of the rim + the spacer = the length of the stud. The length of the stud is 75mm because stock bolts have about 30mm of thread, then you add 20mm of spacer so you need 50mm of thread. The 75mm studs have 50mm of thread.

if you rub in the rear you can roll

TJ? Something you wanna confess?
