Suspension Weight Savings
 

What are some parts of the suspension that can be replaced for weight savings? I understand suspension is more than just replacing parts with lighter stronger ones but i'm curious as to how much weight can be saved in this department.

For example, how much weight can be saved by going to coilovers? etc

Thanks!

well not much unless you go with aluminum. a coilover with a smaller diameter spring and shorter body length will help some but the weight savings will be negligible. my guess is that control arms and crossmembers are where the weight fall off the most

There are some hollow front sway bars out there that save a pound or two.

The Essex Sprint brake setup is probably the biggest single unsprung weight savings I read about. 10 lbs per wheel.

Bugger all.

This.

Plus (minus?) some lighter wheels.

I only saved 2lbs total with the KW v3's

When I had Ohlins on my RX8 I saved a good amount and I used swift springs also.

At great expense, fab all the steel components in aluminum. Total weight savings? Who knows, maybe 100 lbs plus. If this car was a Bimmer it might already have it as well as a much richer price tag.

Most of the suspension parts are stamped steel based on the design so using aluminum doesn't really save much weight. There aren't that many suspension parts, you'd be lucky to save 20 lbs total. If you are looking to save a bunch of weight the suspension is probably not the first place to look.

My Feal Suspension coilovers saved 10 pounds total. 4 pounds on each front corner and one pound each rear.

Stock struts and springs F- 15lbs R- 8lbs. 46lbs total
Feal coilovers F- 11lbs R- 7lbs. 36lbs total

If you want to improve handling / performance, forget dampers. You need to go for unsprung weight.

The biggest impact you can have is wheels / brakes since these are rotating and bouncing up and down. Therefore, shedding weight here will improve acceleration and handling.
By taking on the triangles and hubs you'll make an improvement, but not as big as rotating stuff. Also as stated above it's harder to do.

If you're considering changing the dampers to shed weight, just loose the equal amount of weight from the trunk and you'll have more less the same performance increase at a fraction of the price.

I have always worked with Dampers as unsprung weight. The reality is they are kind of bordeline, pat of them is unsprung part isn't.

saved SIXTY lbs using our custom Brakeman brake kit!

Do you have any more details about this? I heard good things about brakeman stuff with the sti guys. Are you using a wrx front kit or something bespoke?

Modification of the sti kit to run a lighter rotor up front and totaly bespoke rear kit. You lose thevrear ebrake though..26 lbs off the front(waveform rotors) 22 with autox rotors 20 with heavy endurance rotors . 23 OFF the rear and 17 from the E brake deletion.
So maximium weight off is 69 lbs...full 4 wheel kit will be under 5K.
Option to remove brake booster and antilock system with a bias adjustable twin mastercylinder systemwill remove another 50 LBS...GETTING READY TO TEST THIS SOON...

I'm going to change your order around abit due to my experiance...ymmv lol

The BIGGEST bang for the buck mods so far have been the PST driveshaft the Brakeman Brakes and the 4.7 final drive and the enkei wheels.
