I am just a dummy on here so please explain how this is better than a welded/reinforced K frame?

Have you tested it's "flex" against a stock and welded reinforced K frame? How did you test it? Show us some results.

The K frame is a very integral part of a cars ability to resist flex.

Lighter does not necessarily mean better.

It's not about the money, it's about improving the cars.

Is this a real improvement?

Weight saving to induce more flex is not an option.

What are the weight differences?

Since we don't know each other I thought I should share with you the car I built in the pic. Yes it has a welded/reinforced K frame and more but no roll cage. It eats SRT8 Challengers on the road course with ease.

So tell me how this new idea will improve lap times?
