The Evo is gonna be crinasty one day...thats what I keep telling myself. Seeing cool stuff like this come out just makes me wanna keep it in the garage more and get paid off.

I thought 3k was the only solution....I always knew it would be a great mod at the scales and for driveability

.....also gotta get the aluminum rear diff carrier from Buscher

yes between the front member, mustache bar and side diff supports you can drop a nice chunk of weight!!

With this driveshaft are you losing 14 pounds of rotating mass? Or are you losing 14 pounds overall including mounts and whatnaught.

95% of it atleast is rotating mass.. not much you can remove that doesnt rotate by going to 2 shafts from 3.. for the price this DS is 100% worth it IMO..

13lbs rotational mass weight savings and a total 14.5 lbs weight savings. so almost the hole thing is rotational savings.

What would the car drive like with a lightweight clutch assembly and lightened driveshaft? Would drivability suffer a lot? I just ordered my Quarter Master clutch today.

You're more likely to stall driving through a parking lot or over a speed bump, but aside from that, driveability shouldn't be affected much.

If anything you may gain a little more "feedback" as the buffer provided by the heavier stock components is reduced.

A drive shaft of the same weight but larger in diameter will have a larger moment of inertia and will essentially rob power. Enough difference in diameter, and even a lighter drive shaft that is larger in diameter can sap more power.

+1 for this guy. He actually understands the math behind this.

I'm wondering whether removing the center joint has an adverse affect on the operating angles of the two remaining joints. Bad angles can lead to accelerated carrier wear and vehicle vibration.
