F80 M3 Track Build

It's only an inch or something but going from an M6 to an M5 I noticed star if the away

The M4 and M3 perform identically. From
What I understand, the larger rear windshield just about evens out the CG despite the M3 being slightly taller (56.1 vs 54.4). Custom seats means lower rails but more headroom for taller drivers and their helmets as well. I'm not the OP but I've always liked the idea of a sporty 4 door sedan on the track. It's like racing Volvo Wagons: they don't look like they belong, but they do.

Agreed. Like OP, I also wanted a dual purpose build in my mind for the M3. Whenever I slap slicks, she looks like she belongs.

Have you considered a KMP race wheel? It's a plug and play race wheel that allows you to maintain M1, M2, Horn, paddle shifters. Truly an amazing product.

Beautifully done but I'll never understand why people cage a 4 door when there is a 2 door option.

4 door looks better, but some like the m4, taste difference, same weight...
Beautiful M3!!!

Sorry, I don't know the paint code. My body shop guy is a wiz and came up with the color. He assures me it's the Ferrari orange. He used it on the hood vents, calipers and M badges. Painted over the BMW red.

Here's a link to a short clip of exhaust.

Now that it's out of the shop I'll get more exhaust at higher reves. Also need to dial in a new tune to compensate for downpipes and 3.5" single & straight pipe.

Here are a few looks at the hood work.

Question, why not gut the front doors, as well as the dash?

Not that much more weight savings and I was going for a finished interior look and feel of a GT3 RS.

I wanted to keep the M buttons and paddle shifters. In order to purchase an aftermarket solution, it's another $1600-$2000. I need a HANS devise more than a quick release wheel.

Nice build, I you running any crank bolt solution?

[/QUOTE]"I do not understand why the exhaust is pointed downwards. I saw this on a porsche race car as well. Is it track regulation? Would anyone care to comment please to explain.[/QUOTE]"

It is most likely turned down to reduce and be able to pass track sound limits. Several tracks have specific decibel limits for events and turn down tips are an easy way to shave off a couple decibels, by directing the sound down and away from the monitoring stations on track.

It's also popular on many street cars for people to have exchangeable turn down tips that they bolt on for a track event then remove when they go home.

I'm just assuming though at the OPs intentions by the looks of his all track focused build. For the Porsche you saw this is 100% the reason. I spend a lot of time on Rennlist and those P-car guys have a ton of methods to pass sound tests.

Anyone else curious about total $ invested? Or is that uncouth of me?

Sick build - would love to see a video of it in action!

Wow that looks great. Super aggressive. And it's nice to see something other than the GTS hood has an option

[F80_M]

Badass build for sure!!!! Now how much can we buy one of these hoods for?

[bryan_G01]

[DRKNEVL]
