Random Q - what year and mileage was your m3 when you got it? Contemplating a similar build and wondering what you got.

front door cards with the speaker are 12lbs each. center console is 9lbs. slicktop headliner is 10lbs. rear "cards" are (with speakers and butlers) are 5lbs each. the rear shelf with speakers is a little over 5lbs as well. there are also some metal pans behind the rear door cards that are good for 3lbs. my single hump conversion saved about 16lbs, but i also drilled the tube, removed insulation, some molded vents, and drilled some plastic. also got rid of the center speaker and radio. i kept the trunk floor so its flat back there, but i take it out for track days because it flops around from the wind.

I was shocked by the weight of the leather door panels, almost 50lbs of door cards in a coupe : especially the rear door cards with extended leather.

no extended leather. i removed the foam gunk and i think some of that lint looking fluff from the door cards and door a while back... but that probably all adds up to about 1.5lbs max... same with the rear door cards. i had them off previously and scalped the carpet beneath.
rear seatbelts are good for like 5lbs, too.

Few updates over the last month, I've done some more weight reduction, installed trackspec vents, Fiberlab Door Cards which are pretty nice but I'm bummed they didn't send a matte set I requested... And most importantly I got some seat time. Can say that even with less power and more weight, this car is a total riot compared to my last E82 track car.
I've found that taller tires (I moved from 285/30 to 275/35) really accentuate the S65's lack of torque. That being said, I've decided to upgrade to a 6 clutch ZF LSD (similar to DiffsOnline) with 3.45 gearing. The diff should be here in 1-2 weeks, cannot wait to try it out at some local tracks. I also decided to bump up my wing size to the GT4 MK2 after some hairy ~100mph oversteer at Thunderhill/Laguna... don't expect a major change but hoping this will help along w/ some suspension test/tuning later this month.

How did you order the fiberlab door card. Online? How long did it take to arrive? Great job.

I just ordered them on their website but I'd definitely call and request matte as I tried to order matte but received gloss. Lead time with shipping was only 2-3 weeks... I'm really happy with the car, running faster than my E82 at most tracks (except Thunderhill West) with much less power/aero. I also love being able to occasionally street drive to the track with AC, run all day and drive home. BW13: 1:57.3 T-Hill: 1:58.8 T-Hill West: 1:23.1 Excited to get the 3.45 LSD + bigger GT4 Wing installed before running Buttonwillow in cooler weather. Need that sub 1:55 like the cool kids.

But also considering a aftermarket dash that also acts as lap timer. Plus provided many other engine vitals. Been working on the CAD design to fit it. Still have most of the interior. Just rear seat out for the cage fitment. I got a upgraded mechanical LSD 3 clutch pack. Stock gears. It helps a lot. My times BW13 1:56.2 T-Hill west 1:24.2 Laguna 1:39.8 Curious to see your e82 build. When you going to BW again?

It's hard to beat AIM given how much market share they have around data loggin. You'll be hard pressed to find someone not running a basic AIM setup.
Yes the software sucks. But it's such a powerful tool.

Running both might make the most sense, or the Garmin system but I really don't want an iPad on my dash.

The AIM dash I was planning to install is a MXM unit. It does all the regular race dash and all that a solo 2 DL does with Bluetooth.

The E92 M3 with an AIM device connected to the CAN bus is special. The AIM can log data that I have not seen available on other cars. To improve as a driver that data can be very very useful.
The new RS3Analysis is much better than RS2, but still not easy. I also don't have time or the setup to look at the data mid day, but I spend a lot of time at home to look at staff. For example, I would like to know where, and if, the car went into the ABS. With AIM telling me how much PSI I applied, how much pressure was applied to individual wheel, and a math channel to tells me if the wheel pressure fluctuate up and down (while I increase pressure) I can see if applying more pressure will make any different. If not, I know I can not move the braking point any closer to the turn since I am already in ABS. More specifically, I can see if the front or the rears are in ABS. so above is one thing out of several that I analyze at home. |

I was surprised to find out that DiffsOnline just uses that same E39 ZF LSD with new clutches for all of their offerings. I ran this on my last car and it was pretty damn good, wish a Drexler Race-Light was in my budget but $6k+ is kinda extreme.

Plan to install some padded "alcantera" material to the arm rest area to add to the OEM+ look and make them less slippery for long drives to the track.
