Front springs only on G80 M3

Team Tonka · 08-05-2022, 10:48 AM

So anyone else noticed the below yet? Or is it just me? Maybe its hitting the bump stops? Notice it mostly when going over little bumps in the road or even road cracks the most. On the highway and smooth surfaces I don't hear it....

Photos are drivers side spring, raised up on a floor jack. If I grab the springs they are solid, no moving them or wiggling them around!

It's also hard to decipher if coming from the front of the car or rear. More of something I hear vs. feal.

This simply could be that I'm getting more miles on the car, around 2300mi, which means around 700ish on the front lowering springs. It's not something I noticed prior to the front spring install, nor right after, but only as of more recently.

Anyone else noticed anything similar after the front only lowering springs install?

FWIW I had an aftermarket rear shock mount bearing go bad on a car once and it sounded like something rattling around on rough surfaces. replaced the shock mount and it went away for good. Is it both sides? If it's one side maybe something is loose?

Impossible to tell if its from one side or both, or even from the front of the car for that matter...

So I've had mine in for 2-3 weeks now and I haven't experienced any out of the ordinary noises. I'll keep an ear out and report back if I do though. Maybe it's a loose screw or nut that wasn't tightened all the way and it's backed out enough to rattle on bumps?

I had my AST springs removed and went to stock rear and Eibach front.

The car doesn’t feel broken anymore and it looks better too. Also no scraping even on speed bumps.

Which front lip or splitter are you running? Looks great.

Alpha N splitter, love the subtle look. And thanks!

I'm getting a noise in the rear passenger side. It's intermittent and mostly at parking lot speed or pulling out driveway. I didn't have new bolts replaced when installed and wondering if this is the case. My fronts were making noise and had them reinstalled and now no noise.

Team Tonka · 08-08-2022, 11:34 AM

What bolts up front are meant to be only a one-time use?

I'm sorry, it's for the rear and it's actually a nut.

Any other angle pics of the wheels. Trying to see if I should go 15mm spacers all around. I’m on same wheels with ps4s and thinking of dropping the front only.

@Southern
Do you with the 15mm in the front at all? With the pzeros and on the front springs?

I had the 15mm on for a few weeks, no rubbing whatsoever with Pirellis. I ended up switching to 12mm square about a week ago.

Here's a few others. I don't have a close up but let me know. The front is now a 2 finger gap in the fender.

How much did this cost everyone who did it?

It's gonna vary depending on how much your shop charges per hour but mine took 2hrs.

Can someone provide the name/part number of the one time use bolts that should be replaced when installing eibach front springs only?

No rubbing with the 15mm spacers all around? Even with full turn of steering wheel?

Do you have a pic of the front end? Have the same splitters on order. Want to see how much clearance on the front with the front springs lowered.
