Handling before and after spacers

kani179 · 08-26-2022, 11:31 AM

What's up everyone.

Just installed 15f/12r spacers on my 2021 comp. (not lowered). I noticed that the car slides out more ripping around turns. Before the spacers this thing was on rails. I would think with spacers it's a wider stance so handling should be better.

Anyone else experience less traction around turns with spacers on ?

Thanks

Adding spacers still changes the overall suspension geometry from factory, not limited to just a wider stance.
Many things can change when changing one variable.

as he said^ it changes things.. How much, negligible to be felt on the street.

I just put spacers on two weeks ago, car feels the same. Did around 145 in Mexico car felt the same as prior.

I suspect you weren’t cornering at the threshold doing 145 though. Lol

Probably need an alignment to bring it back to spec, and or and negative chamber.

I noticed no changes from installing spacers. If you did the typical 11 or 12 mm front and 15mm rear, you are adding around 1” of track and that should not make a difference the average person can feel on the street. Maybe an experienced track driver could feel it or maybe lap times would show a change.

I put 15mm spacers on my, at the time new, 2015 M4. I instantly found the steering to be noticeably slower, not as sharp on turn in, and no matter how many times i tried fitting, cleaning the mating surfaces, then refitting, i had a steering vibration at 85mph. As soon as i took the spacers off, and tested again, the steering, and turn in was spot on. So spacers are not for me.

I will look into that. Thank you

I am experiencing the same thing. The steering is not as sharp and I do feel a little vibration at around 80-90 mph as well.

Thanks for the input.

To those feeling vibrations -- did you use longer wheel bolts to account for the spacers? Did you use a grease/paste to mate the *clean* surface of the hub and spacer?

I got the spacers from ind. They provided me with longer wheel bolts. As far as grease and paste, I'm not sure the company that powder coated my wheels put the spacers on.

I had 12f/10r on my 2018 m5 and didn't have any issues.

You think it's the size of the spacers ? Do I have to get an alignment done ?
