JG,

I agree with you, but my experience has only been with rear wheel drive cars. When disagreements arose about what I said I kept quiet for that reason. I am confident that I'm correct though.

The PT has natural understeer (push) from the factory. You can get it to a more neutral point by adding a rear anti-roll bar. Too much rear anti-roll bar and you'll get into oversteer (loose). Sure you want to increase contact patch, but if you start to lift the inside wheel in a turn you lose it.

That's why I always recommend buying a set from the same manufacturer. They've engineered the front and rear bars to create the right balance. It takes guess work out of the equation.

I honestly don't know what effects a strut tower bar would have. If I had to guess I would say that stiffening the front end with a strut tower bar would add to understeer, but it may have different effects than anti-roll bars do.
