I know, some of you have had these fitted on your car , looks gorgeous!
Also improves the handling first of all combined with ACS springs.

However, you can hear so many disadvantage of them too for example they shorten the life of the wheel bearings, the arm of force is bigger , suspension parts have get in different position.

What's your opinion ?

Definitely talking here about thin, 12-15 mm spacers , not the >20 mm one.

d4springer said his had no effect on the handling.

[JonD]

In theory the wider track should improve handling, however as Teaston says I couldn't tell any differance to be honest.

Does anyone have before and after pics, preferred manufacturer and perhaps ideal widths. I guess it's car type dependent.

You're unlikely to feel the difference in handling unless you are extremely sensitive (like Nick ). It's all about the look. Our wheels use a more aggressive offset than standard which has much the same effect and there is no measurable impact on the life of wheel bearings or suspension components using these. You're not altering the geometry of the suspension. The only difference, to my mind, between using a spacer and a more aggressive offset wheel is that the spacer is a separate part instead of part of the wheel casting. There may be issues with tyre rubbing if you go too far and you will need the correct length locking wheel bolts but apart from that they shouldn't cause any problems.

Mark sent me very good before and after pictures, he has 12-15 mm as well, Eibach, looks great!If you read this Mark, would you mind uploading them here as well ?

[JonD]

Not sure if F30 has more clearance than the F32, burger recommended not to exceed 10mm F and 15mm R, however I notiiced a lot of our American friends seem to be going with 12mm F on F30's

One thing to bear in mind if you are copying someone else's setup is tyre brand and model. Tyre sizes are nominal and a "255" in one brand could be as much as 10mm different in actual width to another brand (or even same brand, different model). Even tyres of the same actual width can be a different shape (some are more square, others more round) so it's not by any means guaranteed that you can run the same spacers as the next guy if you have different tyres. The only way to be sure that you won't have rubbing issues is to copy identical setups.

Very true, always best to measure the distance on your own car for the reason Lorcan describes

???

255 mm is 255 mm. Not 245 or 265 , I suppose.. Where the difference would come from ?

[DB9506]

I have 13mm H&R s pacers on the rear only.

It definately improves the car's looks, however it also definaltey increases understeer also.

On the limited sizes your quote I do not envisage any bearings issues. Over 20mm perhaps.....

I guess you have to measure your own car, from wheel arch to the tyre and go with a spacer to fit inside this measurement. It seems a bit of a faff, does it look a lot better?

Yes it depends on lots of factors. Which mould the tyre came from. Which wheel size it is fitted to. Pressure, temperature, the shape of the sidewall. Like I said, the tyre size is nominal not actual, like those 30" waist jeans you can't fit into anymore.

[Tengocity]

Well timed thread given my spacers arrived today!

I've gone for same set up as Mark and D4springer so don't expect any issues.

Surprised to hear that just 15mm spacers on the back has appreciable effect on increasing understeer though!

I've done that as well. The question is how much lower will the car be when I load the boot also with passengers ?
(just asking 95% boot is empty)

Hi,
What size, type and where did you buy them?

Let say, 2 cars, F30, 335xdrive, both stock (or both ACS springs) , same wheels, same syze of tyre. Still different ?

19" 255/35 and 20" 255/30 has exactly the same circumference.

Does anybody use wider tyres maybe on the rear ?

Have you seen this car, guy put 255/30 R20 all around, car is just amazing ! http://f30.bimmerpost.com/forums/sho...d.php?t=667029

Me too , would expect the opposite.. Not on the xdrive anyway

Share some good picture once you fit them

Did you order conversion kit as well ? Or longer studs ?

Courtesy of D4Springer:

"I purchased the parts from CA International (http://www.ca-int.co.uk)

Their website is crap, it's best to just phone them, can't recall the name of the guy I spoke to but he was very helpful and explained everything to me in detail. I initially called them about the Macht Schnell spacers but they explained the Eibach's were better, a bit cheaper and TUV approved (also didn't realise Macht Schnell is American!).

Basically the Eibach Spacers come as a pair and so I have two seperate boxes for the front and rear wheels accordingly. Also there is the Stud Conversion Kit.

There are part numbers on each of the two boxes but I'm not sure if these are CA's own part numbers or Eibach's

12mm; Pro-Spacer 120/5-72,5-160 S90-2-12-002

15mm; Pro-Spacer 120/5-72,5-160 S90-2-15-001

The Stud Conversion Kit unfortunately came in a plastic bag and doesn't seem to have a part number as such.

You don't need the conversion kit, the Eibach's come with longer bolts to fix the wheels back on, however the conversion kit was recommended as they are stronger and safer (plus look better, easier to fit the wheel if you are going to do it yourself etc...), if you are going to change over to winter wheels this will help as the studs are fitted to the hub first so you have something to hang the wheel on whilst you tighten the bolts up."

I phoned Roy at CA last week and the parts arrived today as above.

Great, thank you!
