It would be nice to use a straight style bar like these since it is super easy to try different spring rates.
I've found that it is far more effective to go for a stiffer spring at the back. I've spent a lot of time over the years driving various historic rally cars. As a basic rule of thumb what I've found works is a front spring that is fairly close to the factory rate but gives a lower ride height. Very stiff front springs can make the front do weird things.

The front IPD bar works well.

The rear IPD bar doesn't suit hard driving.

Lower stiffer rear spring.

The PV about 10 seconds into this clip is the one I spent a lot of time on. I built it for the guy driving it about 6 years ago.
