PhilT3 (PT3)

Being a simple 4-point harness baR / roll bar, the change (IF it exists) would be so minor you wouldn't feel it.

I wouldn't suggest it if you want to firm up the chassis....esp since you'll be adding 45-50-ish lbs.

A 'roll cage' is a very different thing.

In a controlled test setting, there is a measurable difference. Driving on the street under normal conditions, feeling any difference would be negligible. Under track conditions it is conceivable that it'd feel slightly more planted (but not by very much). As Phil described, that isn't the primary function of this bar.

The GT3RS is a properly stiff chassis from the outset. It was a different story with a bmw Group2 E9 CSL I worked on recently. Putting a simple 1" brace bar across the middle of the bare chassis made a huge difference...how times change.

Rob, appreciate the invite!
