I'm curious who made the 4 bar kit? It appears from the photos that the bars are all wrong on the angles. Any setups I've installed for a street car the lower bar is parallel with the ground. On a drag race 4 bar set up, the bars are different lengths with the top bar being shorter but even then at the highest setting the lower bar is only a few degrees above parallel... I've always mouned my coilovers vertical, as viewed from the side and not more then 20 degrees in at the top as viewed from the rear... It looks like this setup would need either A. a lower front mount for the lower bar, or B. you will need a very deep C notch in your frame rail to move the rear end up enough to ge the bottom bar parallel with the ground...

I just don't see where that setup is going to give a good ride or decent handling.....
