wheel spacers

[z31maniac]

i am no tire jockeys but i know how physics work and extending a wheel hub out it puts extra pressure on the wheel bearing thus will cause it to prematurely fail

Then please run the numbers through the appropriate formulas showing what the hub load is, with and without spacers at varying widths.

Then take those numbers and compare them to projected average service life of the wheels bearings and load capacities for which they are designed.

Otherwise, you are spouting off a bunch of crap you have heard others say.

So let me ask this. What would be the difference between running an et0 wheel vs an et20 wheel with a 20mm spacer. Would they not put the same load on a bearing?

Depends on the wheel and spacer design. You will not notice any accelerated bearing wear despite what some will try and tell you. Very few of my setups are run without spacers, and I have been doing it for nearly 6 years.

Just get your spacers, and make sure you tighten to torque specs. Also double check them every so often.

A wheel with et0 and a wheel with et20 + 20mm spacers with both have the same offset, and therefore will have the exact same leverage on the wheel bearings.

Wont the load plane change though? Granted it would be minimal in comparison to the diameter of the bearing.

Keep talking! searching around it doesnt seem like there is a definitive thread on spacers.

[Van Westervelt]

At the end of the day, if you pay attention to what you are doing, and monitor them, spacers are perfectly safe and wont cause bearings to go bad really any faster than larger low offset wheels.

Do you exclusively run H&Rs?

[Van Westervelt]

I use H&R predominantly. I use the TMS 8's and 10's. I also have used some of my own, out of billet aluminum for rotor spacers and the like.

Cool, i dont need spacers for my current setup, but i might be changing it up soon, good to know

This is what i was thinking which is why i thought it was stupid that some people bitch about running spacers if you were just running them to get the correct backspacing in general for them wheel. Thank you for clearing that up.

did the OP buy these and did they work? I'm trying to find 10mm hubcentric spacers...

Are these junk? http://cgi.ebay.com/ebaymotors/VW-Je...261510004r8346

Or these?

+1?? and when if at all do you need to get longer lug bolts??? or goto studs??

You need to measure really. I am planning on going with 90mm Turner studs either way, I just need some spacers. I have deep bolt holes on my Borbet Type C's so 90mm seem to be the best way to go.

I did find this in my search:

"Footnote
3 All DR-Systems require longer wheel bolts. These must be ordered separately. When ordering wheel bolts, please follow these guidelines:
a) If possible, name the brand of wheel.

b) New bolts must be longer than the original bolts by the width of the wheel spacer used.

c) The bolt head must be identical to the existing bolt:
Taper 60° End digit 01
Round head for M12/d24 mm, for M14/d28 mm End digit 02
Round head for M12/d26 mm (e.g. OE VAG-wheels) End digit 03
Flat head for Porsche original wheels M14 x 1.5 End digit 06


d) Safety guidelines
(Minimum number of turns for wheel bolts / nuts):
M12 x 1.25 = 8.0 turns = approx. 10 mm of load bearing shaft length
M12 x 1.50 = 6.5 turns = approx. 10 mm of load bearing shaft length
M12 x 1.75 = 6.5 turns = approx. 12 mm of load bearing shaft length
M14 x 1.25 = 9.0 turns = approx. 12mm of load bearing shaft length
M14 x 1.50 = 7.5 turns = approx. 12 mm of load bearing shaft length
1/2" UNF = 8.0 turns = approx. 11 mm of load bearing shaft length


e) Please ensure that the wheel bolts do not damage any part of the brake system (ABS sensors, etc.). Turn the wheel by hand and check clearance on the inside of the hub. The wheel should rotate freely. (Maximum tolerance for some vehicles is only 2mm -- i.e. Rear Axle Mercedes). "

Has anything positive come from running the ECS spacers? Any issues?
