what spacers

[macsbm]

Hi chaps got 17 inch wheels on my car with 225×45×17 tryes running eibach springs all round on oem shocks and struts want to know whay size spacers would look the best thanks in advance for your input.

15mm front 20mm rear is the usual suspect

Just fitted some 12mm front 20mm rear to mine, hopefully have some decent pics tomorrow.

Im on eibachs with bilstein kit.

Sorry to hijack the thread, but would that work for 18" staggered wheel setup?
Been thinking of spacers for a little while, but still running standard suspension.
Thanks, Daz

I ran those sized spacers with my elipsoids, no rubbing issues & filled the arches nicely

Thanks. I remember a few posts recommending some stockists so now onto the search facility and then eBay!

I ran 15/20mm with m/sport suspension and 107+ 108's and suffered from a slight rub on the front inner arches where the wing meets bumper area FYI

10mm all round lowered and no rubbing. I specifically avoided thicker ones on the rear as whilst they fit it widens the rear track more than the front which increases understeer...

Interesting. Never come across this before

20mm @ rear on 108's and front @ stock cos it looks good from certain angles, although I'm tempted to go 12mm max at front.
10mm spacers are prone to cracking/failing I understand and 15mm+on the front can bring rubbing issues.

I've heard that about the 15. Never knew 10's cracked? Surely some sort of bad batch?

Only what I've read here and @ M3cutters. Left my E46 M3 stock due to potential issues.
It's easy to imagine as the amount of load transferring through the radial load-paths from lugholes to centre hole is prob quite high with not much material to dissipate or support it.
Would be interesting to model it in ANSYS. hmmm, maybe a little weekend project....

You can buy spacers much less thick than 10mm so they're hardly not strong enough. From what I heard it was mainly Eibachs, I have H&Rs no problem whatsoever.

While we're discussing spacers. Has anyone got the bolt on type, with integral thread? As opposed to spacers with longer bolts?

Seek below as pictures 'say one billion words'

I played safe and went for the long bolt type being that my 20's are on the back.
I drew a mental anaelogy of seeing a second person holding on to the feet of the person who was holding onto the hands of the person dangling over the ledge of a tall building when I looked at the bolt-on type. lol
U learn about risk-driven design when ur an engineer - there's a direct correlation between the risk of something going bang and the number of components involved in any load-bearing system. Which I suppose is why Colin Chapman tried to keep everything as simple as possible.

Found this link and it's very interesting.

Hi Chris. I'm thinking of doing the spacer mod.
What sizes did you use? I'm thinking 15mm front and 20mm rear.
Did you use the long bolt through spacers for both front and back?
What make of spacers did you buy and where from?
Have you run into any problems, or would you have done anything differently with hindsight?

 

[Chris_D]

hi mate. i went with 20's on the rears. long bolt through type and not threaded to the spacers so no primary mechanical connection, only secondary loading through the bolt holes and hub-to-spacer relationship held under tension, which imo is the best option as any deviation or big knock could have greater knock-on effect to the hub with the threaded type. i also reckon stress fractures could occur with the threaded due to the thinness of material in places. i might be wrong but that's just my engineer head telling me what it thinks. would make a very good ANSYS/MATLAB project perhaps? :wink:
I've got a set of 15's waiting to go on the front when the winter wheels come off but i sort of like the exaggerated stance of stock front and 20's rear, esp on the 108's.
will have to dig into the ebay history to check the make but i bought them after seeing that somebofy else here bought a pair and seemed happy with them....
you'll be reet with 15/20 on stock 18" rims but any bigger and you might get arch rubbing issues....

A 40mm track increase at the rear relative to the front is just asking for understeer.
