NEW FOUR LINK

ok guys I have had a 2 link and had no problems with it. But i am wanting to do a four link. I am gonna get the superlift from gravity-werx.com. I have a mazda and i am putting a 4.3 in it. would it be better to run forward or reverse. I was kind of wanting to put my gas tank back in the stock location. so I know I wouldn't be able to run the bars forward in this case. Just curious if anyone else has powerful motors in PUNY mazdas and maybe runnin the bars reverse....
