Now you guys are talking about all these physics when in fact about 80-90% of the people who buy them or consider them are only going to do simple i/h/e rims system kit/lip and basically stop.

They are not all going for all out power in reality, so although the physic's is important but when talking physic's for a item that will be adding a mere 4whp probally won't be all that crucial in the end since they are doing basica bolt on's.
