They help with body roll. Yes they do help. But if Im correct our P Cars already have one on them in the front of the car and its supposed to be a good one already. I might be wrong though

They help reduce flex in the top of the shock towers/strut domes. This helps minimize alignment changes under extreme loading. IMO, this is minimal to begin with since the top of the struts do not have much lateral load on them to begin with. It's not like the fenders are bending into the hood and chipping the paint.

They will not reduce body roll. Porsche has pretty beefy strut braces triangulated with the firewall on 986/996 cars. The aftermarket ones I've seen are pretty whimpy compared to the factory ones, and therefore I further seriously doubt they would do any good. Of course proponents claim they are the greatest thing since sliced bread. A friend of mine put them in and confirmed no difference.

I think these bars do have a place in front engined cars with longer hoods where the shock towers are located in the middle of the fender and where there is a lot of body flex. Porsche builds a pretty solid body. If you have a 986 or a 996 cab, the flex is in the middle of the car and not the ends.

Personally, I wouldn't add them if they were free because they would not even be worth their weight. There are tons of other modifications to the suspension from simple tire pressure changes and alignment changes that will net you far more gains.

Yes, I agree...they do lighten the wallet nothing more. they help on air cooled p-cars being the struts are further up front. the firewall on the 996 does a great job on flex.
