My e92 is a single hump mostly stripper, and she sits at 3550 with a half tank of gas. Add me and I'm close to 3800.

Please don't tell me it's titanium nuts and bolts!

LOL My car weighs in at 3450 without me and it's heavy af with DCT and Sunroof! You need to ditch those stock seats and battery and you'll find yourself 100lbs

Yeah - I'm back to thinking about seats. I want to pick your brain about this at the BMW event. Are you having any trouble getting your wheels in the back seat now?

Ya have to dump dollars into lighter header back exhaust, seats, battery, and wheels. I believe they're the primary savings items.

Yes/no, It's a little more difficult but not bad. Depends on the wheel width

Here's the car weight with a little less than 1/2 a tank.



Still a very complete interior and easy to put everything back.



Seems to be a combination of a few important light parts.

StopTech ST40 front/rear (not sure on weight savings but have to be less)
SPL front arms (not sure on weight savings but definitely less)
MS x pipe (23lbs vs stock 47lbs)
Akrapovic titanium rear section (26lbs vs stock 55lbs)
Antigravity battery (13.8lbs vs stock 60lbs)
No trunk liner but still have all the foam underneath (10lbs?)
Back seat removed but still have full center console (60ish lbs)
Pass seat removed (60ish lbs)
Single Recaro Pole Position, leather, with steel side mounts and old style MS floor mounts (actually replaced with a new Sparco QRT Evo and the new MS mounts, so shaved more weight for sure)
Titan7 18x10.5 wheels with 295 A052's
MCS 1WNR's (MCS stuff feels lighter than all other coilovers I've picked up, but can't say for sure)

Build thread here, not sure why mods moved it to the Pics forum, because track forum is where my heart is <3

When calculating TBL, make sure to disable first and last lap when using AIM . It's rare for a good driver to have a gap of more than 1 second between best lap and TBL.

Yeah, I am surprised by it as well. Usually agree it's only a second or so and I'll double check it tonight but pretty much always try to disable all the start/stops for the TBL. I have everything on video so maybe going to see if I can't stich something together Garmin Catalyst style to look at.

My E90 6MT juuuust scrapes under 3400 on light fuel now, without driver. With full stock interior. Just sprinkle money on it lol. The car is quicker, by a lot, on Conti ECS at the same track than it used to be on Hankooks at 130+lb heavier. Not a shocker that's a whole passenger over more than a minute-long lap, but I was surprised it was quicke ron the contis, I would have expected it to be a wash at best.

I need to not see all these posts about removing back seats and the passenger seat, and not add up where that would land my car on the scales, lol

Oh, btw, the trunklid trim doesn't do anything and weighs about 2.1lb. Tape a couple pieces of cut rubber fuel hose over the hand grab holes in the sheetmetal. Tape up the emergency release. -2 seconds/lap. YOU'RE WELCOME

2009 E90 M3
Track/course: Chuckwalla CW
Best Lap Time: 1:50.83 (transponder)
Brakes: AP Racing - Front: Essex 9668 Radi-CAL. Rear: Essex 9449 Radi-CAL
Pads: Cobalt Friction XR1 front/XR2 rear
Tires: Front: Pirelli DH 305/645/18. Rear: Yokohama A005 Soft 300/650/18
Suspension: MCS 3-way remote
Other mods: VF620, car is gutted with full roll cage, APR 67" GT-250 wing, carbon lip, APR front splitter, AJ Hartmann Canards, Track Spec Hood Vents, Akrapovic X-Pipe, exhaust: straight through with resonators, do88 DCT cooler, RD Sport front sway bar, Recaro Pro Racer halo seat, Slon-Workshop DCT oil pan, DSC-off, carbon doors, carbon blank headlight delete

New track surface, new suspension, first time at Chuckwalla with carbon doors. Tires were not new. Pirellis were actually pretty old. But they gripped better than the Yoko mid-corner, and there's lots of long mid-cornering at Chuckwalla, so the times were quite a bit better with the Pirellis on the front.

Day 2 at Chuckwalla, I was wondering if the Pirelli story from the previous day would repeat. This CCW day, I started with brand new Yoko Softs on the front. The old Pirellis were still faster in the corners than the new Yokos......unexpected outcome.

Fast lap:

3 x 1:49 laps (with an cool down lap in between):

Been a couple months off, but some freak weeks of weather allowed us to have the first track day on the fresh repave and re-curb. The surface felt less grippy than before, but the track is much faster. The lines really opened up with the wider, smooth curbs. Well, until April...

Cold day with rain overnight and in the morning. Track never reached optimal. I was driving cautiously because of the track condition and some serious knockback issues. Car has a lot more in it for sure, but a PB is a PB!

[roastbeef]

i think you can add anti-knockback springs to those st40's if thats an option for you. if you're having to double tap in a couple of corners thats more than a few tenths.
