That would make the standard alu hood ( 150 - 30 ) x 2 = 240 lbs. Sounds heavy.
Note: According to this guy the alu hood is 22.8 lbs

This would make the savings from the seats 150 - ( 22.8 / 2 ) lbs = 138.6 lbs. With that in mind 50 lbs sounds rather modest. |
Ugh...
- BMW can't even decide (through C&D) if they saved 100 or 150 lbs in the CRT...,

BMW says that, while the official weight savings is 100 pounds, if all this equipment is considered, the real savings is over 150 pounds.

WTF does that even mean?
- Even more importantly, the OEM seats weigh (combined) 108 lb (the number I quoted above was only the right seat. Here is the link to that being documented. How in the hell can you save more than the parts weigh in the first place?
