What if 2015 IRS can be retrofit into a S197?

Link?

How is that even physically possible? Is it made out of plastic?

I'd believe that when I see it. Two hundred pounds is an incredible amount of weight to remove from a car entirely, let alone from just the rear end itself. Especially one with even more moving parts on it.

There you go. I assume MT and C&D have the same source since they are sibling companies and regurgitate the same info. It's much more realistic than the crazy, initial 400 pound rumor.

My guess is that it's all aluminum control arms. I hope it's strong based upon the power they plan to make for this platform

"The new “S550” chassis sits underneath this convertible, and it not only brings an independent rear suspension—finally—but also saves a couple hundred pounds of weight over the old car. Cutting out some fat not only will help efficiency but should also be a boon to both ride and handling."


They aren't saying the rear-end is 200lbs lighter, they are saying the whole car is a couple hundred pounds lighter which makes much more sense.

Hopefully the IRS is a vast improvement over that junky one from 2003. We will just have to wait to see.

I find myself very leary of the 2015 Mustang. Take all of the quirks of the current Coyote issues like the questionable durability of the motor itself and the MT82, then add to that a new IRS and platform that will be unproven. Wow, big gamble on a new performance car.
