Weight Reduction Data Compilation

sirantsE90 · 09-11-2013, 03:19 PM

How often do you guys take into account the balance of the car? I have had the the muffler and secondary cats out for a while but just removed the entire back seat and the trunk floor. Dropping the 50+ pounds made a real difference but loosing that much weight plus the rear section of the exhaust feels likes its a bit light in the rear now?

Already have non-power seats up front. I know carbon hood might help balance it out but not looking to do that just yet.

thanks guys

I've just deleted the gf with her handbag and saved some 103 lbs sprung weight. Suggesting everyone should do the same...

If I keep taking stuff out of the car and making it louder I might be in the same boat. "Your car is inconvenient, and not a f***ing race car"

Anyone weighed the front fenders on an E90 to see what they weigh? I am thinking of having some made in fiberglass. Want to know if it would be worth it. If balance is key, then I imagine it would be useful for those lightening the rear of the car.

I ordered Lithium-Ion battery 6.6 Lbs to replace my original OEM. Will let you know if there are any issues. I should get it in two weeks.

Battery is awesome no issues and a huge weight reduction. No issues at 31 deg F. I will continue to monitor cold weather operation. Also it appears that I am getting 1 mpg improvement with 265 and 235 PSS tires. The car was excellent at Summit hpde a month ago.

What did you use to cover the hole? It looks like bamboo or something.

I got it at stableenergies.com. I asked plenty of questions and they were very helpful. I think it is a no brainer. My Indy installed it. They made a mount but you can also buy one. Other than that it is a pnp just like any other battery.

*** Battery update: as you know we had some very cold weather around here recently. My car is always garaged but I wanted to test the battery operation and left it outside to cold soak. The battery works OK (slow/slower crank but starts w/o issues) until around 20 deg or so. Below 15-20 deg it is a high risk the car would not start. I tried to start it at 7 deg F and it was a NO GO. However, there were members that were posting their cars would not start even with the standard battery. So far I am impressed with it and for cars that are in climates where temps don't drop below 20 deg F frequently it would work well.

Cheers

Anyone know the weight difference between stock e90 fenders and m3?
