M4 Comp weight reduction

Gottagofast · 03-26-2023, 07:52 PM

I'm getting my new ride in less than two weeks. In Canada, the comp is only available with xDrive, so it's a bit of a glutton.

What aftermarket parts should I look out for to lighten this big boy? The ultimate goal in a few years time, after the factory warranty runs out, is to turn it into a road legal track vehicle.

Does anyone make Titanium exhaust or CF drive shafts for the G80 yet?

i guess you could buy some csl parts. hood, trunk, do a rear seat delete. lighter wheels. does your car already have the cf roof, buckets, and ceramic brakes ?

akrapovic and fi make titanium exhausts.

it will still be heavy though. just enjoy it for what it is. its a daily that can handle the occasional track day and hold its own. its not a full blown track car with license plates like a gt3rs.

Exhaust is a big one. Single mid, exhaust will save you like 50 lbs

Forged wheels are a good way to save weight.
The CCBs aren’t that much of a savings. More rotating mass savings. The larger calipers offset the rotor. I added it up not long ago and it was less than 3lb a wheel.
Not a lot of savings for the cost.

I was looking on a website last week that had a carbon hood and trunk. Carbon Works or something like that. The CSL trunk is like $20k. Not an option.

Looking at the CSL weight savings the center consol was quite a bit of savings.

Overall BMW wasn’t able to shave that much weight off the CSL. The price per pound is not going to be worth getting crazy.

Sell and buy a CSL?

You have to factor that the MSRP was 169 900 + luxury tax + taxes and add a full PPF and cost is around 220k. Ask me how I know 🤣

buckets (22lbs), ccb (42lbs), HRE r101s(30lbs), akra exhaust w/ long link pipes (36.8lbs) are the heavy hitters...

stuff like no exec package, no radar cruise probably save you 15-30lbs also?
