Ok after yesterday's research and today's discussion with one of the mechanical engineers here at my office, whom is a big car buff as well, I think that the HTP crossbar would be mildly beneficial for traction purposes.
Helping with preventing lateral stiffness and underbody structure does aid in developing better traction for straight line. In my learnings of traction bars, they tend to do one of two or sometimes both things.
1. Maintains stability of the axle/lower control arm location (from front to back), thereby maintaining the downward pressure on the shocks towards the pavement. Without this, the axle would be moved forward or backward of the bottom of the strut and the shock would not have a more vertical travel.
2. Some traction bars use the movment of the axle when torque load is applied to redirect forces upon the springs, this I have only seen in a leaf spring application so far and I cannot see this so far on a FWD strut type suspension. Therefore this type of traction bar isn't feasible at the moment on our cars.
Using this knowledge, the first point I make in the previous paragraphs makes sense for using the HTP crossmember and Lakewood Traction Bars as both try to apply excess pressure on one side of the cross member to minimize any arm movement to the front or rear of the car.
***Point of note***
I would think that using the crossbar would be effective, however an LSD and a stiffer suspension setup would be required to gain maximum traction, especially for drag racing applications.
As for myself, I think I'll be purchasing one of these HTP crossmembers as I am replacing both lower control arms in March, which should make things very interesting. B)
