Fixing understeer and body roll
 

My car, like most Mustangs, has a problem with understeer. Coming from a 3 series BMW, it just doesn't handle the way I want it to. Obviously I realize it's a much heavier car with a solid axle, but I would like to address two things: body roll and understeer.

I currently have Vogtland springs with stock struts, BMR panhard bar, and upgraded front sway bar end links. My plan is to purchase Koni STR.Ts to keep the car stabilized and to cut down on body roll, and to purchase a BMR rear sway bar with billet end links to stiffen up the rear and cut down on the understeer.

Does this sound like a solid plan? My biggest reservation is with the BMR rear sway bar. It's quite pricey at $270 and I want to make sure it'll make a difference.

A rear sway bar is a good place to start and should address your needs. The BMW you had can be a tough comparison for your Mustang. I am not up to speed much on the S197, but have an MMRSB #5 on my ride and is wonderful. I am not sure if MM makes one for your year, but worth a look.

Forgot to add a couple things here..

Are you running staggered tires/wheels in front/back?
How much body roll do you have?

As you probably already know, heavier springs are really the way to address body roll and sway bars are really just a fine tuning device. On my own car, I run very light springs, but a pretty heavy rear bar, as mentioned above, to maintain a better ride, but flatten her out a bit on the streets. This is great for the DD side, but not great fix for my AX events.

What are the ULTIMATE goals for your ride?
