Wheel Fitment Experiments with OEM+ M359 19x10 & 19x11

Wheel Fitment Experiments with OEM+ M359 19x10 & 19x11

The Initial Fitment.

Back in November 2021, I first fitted the OEM+ M359 19x10 and 19x11 to my E92 M3. We were in a rush to complete the Drivetrain & Suspension overhaul before Snow showed up as I had to test the craptastic MFactory V3 carbon driveshaft. 

The wheels are 19x10+25 and 19x11+25. I picked Michelin PS4S in 265-30-19 and 295-30-19. The 275-30-19 were backordered. 

We fitted Bilstein B16 Damptronics that I sourced used locally fitted with Turner Motorsport's Hybrid Caster & Camber Plates. 

We ran around -3.0 of camber at the front to achieve the look and fitment we wanted. 

The Quick Fix for the Front.

The front was obviously too low. I decided to raise the front a bit and run a front camber closer to OEM specifications of -1.5

 

The initial fitment issues.

Unfortunately this was a new product for Turner and they shipped the wrong spring perches. I documented the issue and fix here

Essentially, it made the front much lower it should have been, and way bouncier and softer than Bilstein intended as the front springs were barely compressed. 

The B16 springs also eventually settled. It started rubbing at at rear. 

The Updated Fitment.

Once I got the proper spring perches in, it immediately raise the front end and as a result, the rear squatted. 

Causes and effects. 

I lowered the front again back to their lowest position. 

That was easy.

I thus got on my back and went through the painstaking process of raise the rear while the car was on the wrong off jack stands. 

A total pain in the ass as the rear is spring collars are difficult to access. 

One notch and one turn at a time - I eventually made it to this fitment.

The results: 

"Rub free and flush at the rear.
Pretty mild at the front.
It wasn't just right yet"
- Matt

 

The Final Fitment.

Truthfully, I missed the more aggressive camber settings at the front. The turn in was immense with -2.5 and lower negative camber.

Sure, it will eat through tires quicker - but this isn't a daily driver anymore. Fun takes the priority for me. 

I took the 12.5mm spacers off the E60 as I fitted the BBS CHRs.

I recently fitted these to the 19x10+25 to effectively achieve a 19x10+12.5mm final offset with the PS4S 265-30-19. 

The final step is getting it aligned this week to provide you guys with final specs. I went overboard with the most aggressive negative camber settings off the Turner Hybrid plates - it could probably be a bit more mild. 

This is the final result: 

"Flush at all 4 corners. 
No Rubbing. 
Supreme handling. 
Supreme looks (in my opinion!)"

- Matt
