Post exact weights of weight reduction you have done!
 

We all know the evo 8 and 9 weigh a lot. Most of us would like to lighten them up a little bit. So post up your mods you have done to reduce the weight of your evo. Cutting the car up is not allowed here.
this thread is dedicated to all of the weights of the factory parts and all the after market parts. please keep in mind everyone's scales may read a little different then someone else's. so take the info listed as an proximate weight. PM me with any weight's of parts that you do not see listed and i will put them where they belong.

IF YOU NOTICE A INCORRECT WEIGHT AND HAVE THE CORRECT WEIGHT FOR THAT PART PLEASE PM ME AND I WILL UPDATE IT. THANKS

Special thanks go's to the following major contributors for adding a great deal of info to this weight reduction thread.

sounds like a fully gutted racecar.

As far as the A/C compressor and Condensor is concerned, are there any special plugs or caps that are needed to prevent debris from entering in the unit inside the cabin?

EvoIX4me,


Great review.. we just need to know how much your car weights:D .

I am not going to be as detailed as you but here are my weight savings:


Buschur Mini battery kit
Megan Racing Coilovers
K&N filter
main cat removal
Spare tire
Floor mats
Front crash beam removal

My Evo 8 MR weights with 1/8 of gas 3110lbs. Previous weight with stopck suspension was 3136lbs.

(Just for references) only other vehicles that I owned and weighted at the track while racing them:

03 WRX 3042lbs low gas, no spare tire, empty
91 Eclipse GSX 3110 lbs Low gas, no spare, empty
91 Civic SI 2190 lbs full tank gas,no spare tire,empty
98 GTI VR6 2626lbs low gas, no spare tire,empty
94 Stealth R/T TT 3750lbs no gas , no spare tire ,empty
06 GSR Evo 9 3280lbs full tank of gas,empty
05 BMW F650GS 502lbs full tank of gas,empty

Carlos

As far as plugs go I havent found them for the Evo but I am sure you could. Most cars you can buy a little rubber guy that covers the hole through the firewall. I assume thats what you meant.


My car weighs alot because of the huge 10-point cage in it. I still need to remove the door beams but with pretty much full interior (Aside from the rear seat stuff) it weighs ~2950 lbs 1/2 tank gas w/o driver.

I am still hoping to get it to around 2900 race weight so I still go another 200 to go :(

Aside from the cage and different seats the whole front interior looks stock. It just looks like an Evo that someone removed the rear seat out of. The exterior looks stock as well.

I've been following Trina's gutting exercise for a bit now via search. With her and other endeavor's, I've been making a spreadsheet detailing stock weights and aftermarket (or delete) weights comparitively. Here is a snipet of it:

ST, the stock radiator is 10lbs, and my PWR radiator is 12lbs. Not weight savings, but the stock weight is probably useful.

I also have the Megan catless exhaust with restonated test pipe at 40.2lbs, and the catless BR tbe at 30.2lbs including the hangers, nuts/bolts, and slip-fit clamps.
