wheel spacers, advisable?

[tonylim]

Hi guys,


Did the H&R spacers to my E46 M3 long time ago and now with CSL coming home, are spacers advisable for the car? Solely just to make the car looks nicer. i remember it made so much different to the M3 just by adding in the spacers the cars look so mean.

Thanks !

They say adding spacers only to the front helps reduce the slight slow speed understeer the car has.

I have ran 15mm front and 12mm rear for a while now - it certainly helps with aesthetics.

I have same as above, and it improves slow speed understeer with no down sides, as well as looks a lot better.

How much bigger does the spacer in the front need to be to help with the understeer?

I think a square setup would be the better choice if you just want to achieve exactly that.

I wanted to retain the OEM wheels, so went with 15mm front and 12mm rear spacers.

I should add that With square setup i was talking about the tires.

Fitting 265 tyres on an 8½" rim is not a good idea, the Cups in this size are designed for a 9½" item, so on track, will feel like they are trying to roll off such a narrow rim.

It is possible to fit the 9½" rear on the front, but due to the incorrect offset brings with it clearance issues.

Hi mike. Yes of course you need wider wheel. Dont fit 265 on the 8.5" fronts.:whistle:
I think 9" will work however. But that is a different topic altogether.

Back to the topic. Spacers increase track width so make the car more stable and as othere said it can help to dial out some understeer. However the root of that evil lies in the staggered tire setup.

With that said i probably would go for 12mm all around.

Thanks so much guys!!!

Any brand of the spacers you guys would recommend? I guess they are the same as those used on normal E46 M3


Thanks again guys

I run 15mm front and 10mm rears, have done for years with no issues, in fact I had the same if not a similar setup on my old E46 M3's too.

H&R spacers are very good, so are the BIMECC ones.

Make sure you get hubcentric!
