Just got the eibach swaybar kit, i know it's not a net weight reduction, but figured I'd post the weights in case anyone wants to compare to other aftermarket sways

Eibach Front Sway: 4.52 kg
Eibach Rear Sway: 3.80 kg

Stock Front Sway: 3.51 kg
Stock Rear Sway: 1.97 kg

Stock Front endlink: 0.38 kg ea
Stock Rear endlink: 0.20 kg ea

SPL Front endlink: 0.54 kg ea
SPL Rear endlink: 0.39 kg ea

Oh, here's some more weights i measured a while ago and forgot to post:

Did an upgrade from base brakes to sport package with Racing Brake 2pc rotors and pads (ET800).

Stock:
F Rotor: 9.75 kg ea
R Rotor: 5.83 kg ea
F caliper+2pads: 7.55 kg ea
R caliper+2pads: 3.22 kg ea
stock Rear rotor shield removed: .40 kg ea
Total: 53.5 kg

Upgraded:
F RacingBrake Rotor: 10.15 kg ea
R RacingBrake Rotor: 6.95 kg ea
F Sport Caliper+2pads: 5.91 kg ea
R Sport Caliper+2pads: 3.06 kg ea
Total: 52.14 kg

Total weight difference 1.36 kg less than base!

I'm amazed the overall weight still ended up less. Those base calipers are boat anchors compared to the lightweight sport ones that are so much larger.

There were some other fittings and hard lines and things that i didn't factor in, but I think they were roughly the same weight between base and sport.

By the way RJM clutch pedal assemblies weigh 303g less than stock. :icon14:

Also the engine bay has so much over engineering it's crazy...

the block has so many brackets bolted to it to hold hoses and what not...

I haven't weight all my junk but it's around 8lbs of metal...

keep pushing folks...

KaienZ34 05-13-2013 01:07 PM

I'm not sure how accurate my scale is but it read.

OEM springs Font: 4.2lbs each
OEM springs Rear: 4.7lbs each

Yup. This is a ripe area. Too many little things to bother listing, but it's a fair amount of junk weight in just the right place to be removed. All kinds of wiring harness brackets and tiny things to go after. You just have to inventory the 3-D volume of that bay inch by inch as you go through it on major work, and stuff to cut becomes obvious.

You keep saying you're not gonna heavily mod this car... I'm starting not to believe you ;) Every little weight reduction is sucking you in further...
