G82 M4 xDrive Track Build

Steve Gill · 01-31-2022, 02:10 AM

As a follow on from my thread about tracking the standard M4 xDrive, I thought you might be interested in my track build.

Now completely stripped, roll cage installed, interior painted and now ready to start re-installing bits

Peo.K · 01-31-2022, 03:21 AM

This gonna be interesting!

Peo.K · 01-31-2022, 03:24 AM

Are you keeping original brakes or go for AP Racing?
How original brake works on track with racepads?
My F82 with Ceramic brakes and Pagid pads works shit and i hope original steel brakes on G82 is better.

You forgot to remove the steering wheel

Good luck with the build

barryc365 · 01-31-2022, 07:38 AM

Amazing! Love the Schrimer builds

Have the done the kinematics and roll Center correction magic for this car yet?

What suspension did you go with? KW?

GOLFFRR · 01-31-2022, 08:00 AM

sick!! excited to follow along with this.

Rayien · 01-31-2022, 01:02 PM

cant wait to see the those wheels on the car! E88s right..?

jmg · 02-01-2022, 09:33 PM

Epic!

Kevin_The_Clean1 · 02-01-2022, 11:03 PM

It's a Schirmer car , expect NITRON suspension, AP Racing brakes along with E88s as standard equipment.

I'm assuming you've already swapped to SRF fluid in this thing, but your experience and mine seem very different. Are you sure the pads are made for a CCM rotor? In mine, the only weak spot was the fluid - once I put something that would handle the temps these rotors will generate - MUCH higher than steel rotors - all the ills faded away (pun intended).

Further, if you have and the issue is still present, you can swap rotors to traditional steel and keep the heavy duty calipers that you've already paid for - just a pad material swap to correspond with the steels would be needed. Best of luck.

This is the million dollar question - other threads have noted the OEM rear brakes being a major let down on G8x… (edit: not just visually - can't handle track duty)

Imagine my disappointment on finding the same rear caliper on my M3 AND X3 M40i…

Really?! Color me surprised. I'll need to do some digging. This seemed to be one area of needed and delivered improvement from the E9x to the F8x generation - damn shame if they've gone backwards on it.

Backwards being a general statement - with a heavier car carrying more speed and therefore momentum in every manner - I'd expect the same exact brake package to give up earlier.

Now, we know that the brakes from F to G generation aren't anywhere near the same - certainly in the rear. But, I did think the front calipers on the G8x were supposed to be uprated 6 piston parts, a heavier duty piece than the OEM F8x with steel fronts - maybe I'm just recalling bad info. Anyone know if that's incorrect?

TopJimmy · 02-02-2022, 07:52 PM

That cage is friggin

AWESOME!!!

You get the max…5 thumbs up!

My drag car might need an 8.5cert cage soon.

Full disclosure - I don't have my G80 yet (QC purgatory) but I've been following a few threads with folks that are tracking their G8x. My $0.02 - it appears that handling and power are a big jump from F8x. Electronics and brakes are still TBD - looping in beachBmmr to this thread.

Before I get roasted, I have a F80 CS that I track 4-6 weekends a year at my local track (COTA) - for me, a M3 is my DD, kid hauler, and track toy with a few minor mods. If the G8x can do that better than F8x, great - let's do it.

I wonder if Parks BMW will upkeep their warranty on this one. lol
