You're measuring from the bottom of the wheel lip and not the ground, right?

616 mm front, 617 mm rear.

Front: 619.125
Rear:601.345

Are you sure? Looks MUCH lower than the recommended height for 20's. You sure you are measuring as shown in the manual...starting at bottom of rim, not floor.

RElias21 · 10-13-2020, 07:54 PM

625 Front; 605 Rear on a half tank of gas.
Honestly think my rear is a bit low, but raising it up with the spindles has proven to be super difficult. I'm contemplating raising it up to 615 or so at my installer who can uninstall it to rotate the spindles. But, I also don't want the car leaning forward any more than this.

What do you guys think?

Not low enough in the rear I think. And you adjust the perch, not spindle. Spindle is where the wheel hub is on the front.

Car looks great either way!

Sorry for using the wrong terminology.

Regardless, your perspective is interesting.

My rear tire may actually be a hair tucked in under the fender. If anything I would maybe raise the front up a hair so that it sits more level.

Yea it's tough to gauge, for me I like the "big" tire and vertical sidewall look. That's probably part of how I view your ZCP wheel/tire set. The tires look tiny to me.

Haven't measured. Had them installed to factory specs at BMW dealer with 20" FI-R's and MPS4S' a few years ago and it looks and rides great in my view.

Oh it looks great and MP HAS ride great! It's just def not factory recommended height, lol.

Makes sense though if you had a dealer install. They're idiots.

Went out and measured:

Front: 619.125
Rear:601.345

And remembered that they were installed at my indy shop and not at BMW Dealer

Mospeada · 10-14-2020, 06:20 PM

yea just to be consistent, we should be measuring bottom of the wheel to the wheel arch that way tire height, etc. don't matter. some of the pics look great but #s seemed high. anyway, 20" rim on the front looks best in this car, the wheel gap is ginormous... it hides well , but not with 19".

i plan to do corner balance this winter and get it right rather than going by height or appearance since the car is not symmetric (i have MPHAS btw).

TopJimmy · 10-15-2020, 06:56 PM

MP-HAS installed DIY
620mm (24 3/8in) front
608mm (24in) rears
No spacers

Barely a scrape here and there...
And they feel soooo much better then stock springs. Every M should come with them.

horsepower_and_hounds · 10-16-2020, 08:26 AM

remember when measuring and comparing..... note if it is F80 or F82. The rears are way different

Anybody have a screenshot from TIS for the F82 heights?

Is this what you wanted?

horsepower_and_hounds · 10-16-2020, 01:34 PM

No that is for the F80 and posted earlier in the thread.... it shows that on the bottom of the pages. I am looking for the F82. They are very different

If you look closely, the rear picture in the BMW document shoes a coupe, so one could argue these are for the F82

.

BMW specifies same MP-HAS ride height setting as measured from the fender for the M3 and M4. Here's a link to the complete document: https://f80.bimmerpost.com/forums/at...1&d=1484151419

I totally agree and that is what threw me off at first then I seen F80 on the page corner.... either way the front might be close to the same but no way the rear can be. Anyways if i dig deep enough I might find stock numbers on the net but most everything i have sen is generic overall size specs

Have you checked the the full document I linked? The title clearly indicates it is for both F80 and F82 chassis codes (not the F83 though). Further down, it also specifies that the rear MP-HAS spring results in a 5mm lower lowering range for the M3 compared to the M4, which means the stock M3 springs are 5mm longer than the M4 ones.

No missed that...... I am looking for the OEM height specs of a factory car
