are there any bad effects of having them?? i heard from some one they aren't good to put on, is this true?

someone is selling 10 and 15mm and i wanna try them on and see if they will fit with my groun control coilovers and if they do i wanna buy them but i heard from someone that spacers aren't good....he didn't say y tho lol....

anyone... thanx :D

Generally, spacers aren't good, its better to get rims that fit your car OEM - like, however, 10mm spacers still seem OK. There are plenty of people on these boards who run spacers, personally i dont because i dont have to, and likely would elect not to if i could avoid it.

If you are using wheels with the right (stock) offset the spacers can affect the handling characteristics and geometry of the car, for looks, it's cool. Spacers are used primarily for wheels mounted with an offset different from that of your car and in some cases for style and looks.

Use spacers only to correct a wheel with too much offset. While widening the track of your car can improve handling, the side effects aren't worth it: accelerated suspension component wear, increased bump steer, possible fender-to-tire contact, etc...

yes when there are plenty of options out there that dont require spacers i wouldn't consider it.

But e30s suck bcus its hard to find wheels with the right offset, which makes ppl turn to spacers even thou ideally we dont want to.

no, if the spacers had the right design it wouldn't matter.

a proper spacer should be fairly light, hub & wheel centric. A bad spacer may add wear to your hub bearing, that's about it.

well i got the stock M68 rims on now and planning on keeping them for a while...i like the look of the spacers but if it will wear out my suspension then forget about it. and im planning on goin to the track too,... still some ppl say its goo adn some say it's not .....:confused:

Do you need them? Do your wheels currently fit properly? Do the tires clear your fenders and struts?

yeah they fit good they are the stock ones... i just wanted to put them on cuz i seen them on a car and it looks GOOD..

They are as safe as the bolts/studs you secure them with are. Don't listen to heresay, they are perfectly fine.

I know of guys running up to 40mm spacers on the track, with no issues. Just don't cheap out on hardware.

If they fit fine without then there is no point to add spacers. You're adding unspring weight for no apparent reason.

Spacers are commonly used to make OE wheels fit with coil overs or to push the wheel further away from the strut/control arm to allow for larger tires.

In my opinion the wheel should be designed with the proper offset such that spacers are not required.

here are some pics...see how the tires/rims are Aligned with the fender...thats what i want...

I've been using 15mm spacers all around on my Type 44 winter setup for my E46 and I've never had any problems. Just make sure you use the appropriate length bolts.

I hate spacers, I had bad experince with them. I will never use them. they also add stress on your wheel bearing.

^ what bad experience is that?

I'm going to add some 10mm spacers to my front tires, as I currently have a staggered setup for the summer, and my fronts ideally should be sticking out a little more since I don't have M3 control arms which usually push the front tires out a bit. My front tires like to follow the grooves of the road and squirm a bit... just want to try it out and see what happens, experiment a bit I suppose, bring it out a little more to match up with the 255 rear's. My tires have also chewed up my fender linings, as it rubs a bit at full lock.

M3 control arms don't push out the wheels. I have them on my car, I compared them side by side with my stock arms, they just have a wider angle (using the inner and outer ball joints and CA bushing as angle points), which will push the wheel forward (more caster).

Justin e36
02-23-2006, 10:09 AM
hmm... so the control arms themselves are the same. what would the benefit be of negative caster?

What do you think the effects would be of putting 10mm spacers on the front? I have 225's up front, and 255's at the back. (18's). Offset is +35.

No, the control arms are different, that 'L' shape is more open on the M control arm. More caster makes for a more stable car at speed, and it makes the wheels angle to the side when turning. If you've seen an old Mercedes with the front wheels turned to their locks you'd know what I mean.

Aside from having a wider stance, and maybe having some fender contact, I don't see what else you'll get with a 10mm spacer on the front. You'll basically have a 45mm offset wheel. Then again I'm also against staggared wheelsets :P The first thing I did when I bought my car was remove the 7mm spacers I had up front once I had more strut clearance.

I think you mixed it up. When you add a spacer, you reduce the offset, which would give you an effective offset of 25mm in this scenario.

My ET35 wheels with 15mm spacers are effectively ET20.

Yes, i messed that up. Now I feel like an idiot, mostly because I knew that.

Spacers reduce offset.

So on Justins car it'd be like have 5 series rims on it, it'd stick out a lot more then you'd want it to.

Interesting discussion.

Nelson - I know what you mean about the wheels angling, I have an old Mazda pickup truck that does that too. Think I'll try the M3 control arms, can't do much harm. I don't think I'll have any fender contact with 10mm spacers, would I?.. since it doesn't rub when going over bumps when I'm turning already. (fender contact would only affect the rear wheels, no?)

So if 10mm is too much, what would be more suitable for having my front tires match up a little better with my rear tires? I basically just want to experiment to see how it changes the handling, not necessarily to keep... I had my rims drilled to be both hubcentric, and not require spacers when I ordered them from the factory. I kinda like that, and am not too keen about having to shell out more money for longer wheel locks. But my wide 225's on the front BARELY touch the wheel well lining at full lock, to the point where it has eaten away a part of the linings. Don't want it to be rubbing if I get pulled over... so I'm thinking spacers, maybe even 5mm would solve this...

To be honest, now that I have a staggered setup.. I don't really like it. Mainly because of the understeer. Visually it looks pleasing, and I have to admit those 255's on the back stick like glue to the road, and while turning... but also so damn heavy for my little m42 to power. Also not fun that you can't rotate your tires at all. Since the front/backs can't be swapped, and the left/right can't be swapped without dismounting the tires since they're directional.

never had a problem and I also bought extended lugs with the H&R spacers

I had front fender contact with my 235/40/17 with 7mm spacers while auto-xing (hard cornering).

... hmm, and the fender contact went away when you removed the spacers? my wheels aren't touching the fenders afaik, just the fender lining at full lock. think I need to put the car on a hoist and see exactly what's going on from underneath.. hmm.

is that ur all around setup???


BTW i wanna change rims in the future but don't wanna get bigger(18") since it will slow my car down but i want soe lighter 17"s with 255 in the rear ,,, is the doable :D???

You're adding unspring weight for no apparent reason.

I'd be surprised if you could find a 10mm spacer that weighs more than 1lb. Ans even if it did, all of the weight is right at the centre of the wheel. No one on this site can feel under 1lb of unsprung weight located directly on the hub.

Buy two more rear wheels, put them on the front with 245's or so. Problem solved.

Can't use that statement for much if you don't mention the offset.

yes, all around. I don't know what sizes you can stuff under the fenders of an e46.

17x8 ET33 235/40/17 rubs slightly, on a slammed E36 during extreme loads. Good info.

FWIW, there are E36 guys running 17x8.5" ET40 wheels with 245/40/17 or even 255/40/17 all around without issue.

No one will run 255's up front without rubbing the liners at the locks. And in the rear you beat in the inner fender, and roll all 4 fenders, and you're limited to your drop, and front strut choices.

Who is running ET33 rims with that size rubber?

right wheels, right suspension geometry, right tire, you will surprised what will fit.
I run a 18x9.5 up front and 18x10 with 265/35 at all four corners sometimes.

psssssssssssssssh 265 up front, thats for kids. 275 up front 285 rear*wave*

Ohh and BTW i run a 15mm spacer on the front of the 540 to clear the coilovers and have had no issues to date. Make sure they are hubcentric though!

I can run a 275 as well, but the tire I use is not available in a 275/35.

I only had the spacers because the Bilstein PSS struts forced me to.
