Do you guys already have a carbon driveshaft?

 

Thanks for the info Martin. Let us know if you get around to weighing the stock Recaros and seat rails.

And what brand/model scale are you using?

 

Good Info

 

Raw data with a good searchable subject line..

fawkin awsome! thanks for the data set.

 

thanks, good info's.
You can add on some thing like the majority is willing to remove or swap?
I mean the stock front seats weight, or the stereo weight , speakers weight etc?

thanks Rob

 

Amp and bracket - 6.2 lbs.
Speakers (All 4) - 6.2 lbs.
Deck and Sirius unit - 6.3 lbs.

 

thanks
How about the stock seats weight?

 

Wow stock roof is really light, probably not worth replacing. The AC is also much lighter than Evo 9 AC, not much point to take it out at only 20lbs.

Rear bumper beam and tow hooks are crazy heavy, those things must go right away, lol. Spoiler is also pretty damm heavy, thats suprising.

 

you took of 20 lb /ac/ from the very front of the car. it is different effect then you would take out 20 lb under your driving seat.

 

Not yet.... but we do have a prototype Chromoly drive shaft that dropped 11.5 lbs!!!

I really wish the guys were not so busy with the SEMA stuff. There are lots of interesting stuff that needs to be posted!!

 

The weight of the speakers will depend on the system you have. Our white Evo had speakers that were about half the weight of our charcoal Evo.

 

IIRC, the passenger seat weighed 48 lbs. It is probably heavier than the drivers seat as the pass seat has the load gauges and computer on it.

 

Damn these seats are heavy. I need to sell these fat things...

 

This makes me excited to see how much lighter the RS version will be.
