Less (weight) is more.

FL5 Type R.
I realise our cars are not "heavy" per se'

But, as I get older and wiser, I realise Colin Chapman was right.....
"Add lightness"
I was walking around my car last night, stroking the beard and looking for obvious weight savings; without going bezerk and turning it into a race track only kind of deal.
Nothing obviously worthwhile jumped out at me.

I'm sure I'm not the first person to have this circling / beard-stroking / thinking moment.

What say you.. people who have gone before me on this quest? FL5 Specifically.

Target = 100kg / (220 freedom Units).

I appreciate the conversion into “we made it on the moon first” units

do you have passengers? If not. The rear seats can go for sure.

Very rarely, but when I do, it's my kids. So rear seat is out.
I was wondering what the whole lot weighs though......

Oh gotcha. Nevermind that then

gut the trunk?

easy "cheap" light weighting would be a lithium ion battery. Wheels if you still on the heavy stock wheels. Thats probably 70lbs of weight savings right there.

Rear seats is an easy one but silly on a 4 door car, I wager those probably weight like 40/50lbs. Apart from that its gonna start costing a lot. Carbon hood, carbon fenders, carbon trunk. Carbon bucket seats.

200lbs is a ton though, I think for that much you gonna have to gut shit.

Yeah, this feels to be matching with my original thinking last night.... There's probably nothing obvious that I've missed.

These are good ideas. Between wheels and the lighter paragon rotors. That’s like 7-8 pounds a corner no?

Maybe between wheels rotors battery and gutting the trunk. You can drop 60-80 pounds? Anything beyond that might require some aggressive concessions?

Wheels, battery, rotors, exhaust, front seats, wing (or wing delete) can get you to about 160 lbs in weight savings. Not cheap, but that's good weight savings without going nuts and gutting the car.

Keep in mind, the FL5 is under 3,200 pounds. The current gen M3 is 3840 to 3990 pounds. They have almost 600hp and you smoke them around the track completely stock.

We don't need no stinking seat to drive our car! Sitting on the floor saves at least 40lbs

Losing a few pounds could net you a lotta weight

I think stock wheels are 26lbs and a good aftermarket wheel is 18.
Rotors not a significant amount of weight savings.

As was mentiones I forgot exhaus, thats a big one, can save 20 to 30lbs there with a titanium one.
