Default Finished with the scales. Let me know your thoughts.

This is with driver in seat and just over 1/2 tank of gas. Street wheels of equal weight all around. Will help rear balance with a set of Bogarts when I get around to ordering a set.


weights with driver and right side bar preload

left front..............Right front
1018.....................937


Left rear...............Right rear
792.......................802

45% rear weight (best I can get with current setup) Battery relocate may help a little as well as drag wheels.


Ride heights with driver and bar preload on right side.



27 11/16..........................27 11/16


27 13/16..........................27 13/16


Perfect side to side and only 1/8 inch rake to allow for some more fuel to be added. This is the best I can come up with my knowledge. If I am overlooking anything at all please feel free to let me know. I know it is not the ideal drag setup but for a drag setup that I plan on street driving I feel it looks preety good. Now if I could just get the pinion angle setup right I can do my final alignment and ship it.

......Front....................Rear
Left 1018.....................937
Right 792.....................802
......1810....................1739.......3549

If above is correct then weight distribution is 51/49

Shouldn't the alignment and pinion angle have been set before you did all this? I'm just asking and trying to learn. Thanks

Pinion is close just trying to get a response on another thread to fine tune it. The alignment is the last thing you do. Ride heights first obviously since they will change everything. Then scale because you are going to adjust and fine tune the heights for your weights so that would put your alignment off if you had to adjust too much. This is what I was told by a sponsor.

Makes sense, thanks. I don't know by how much, but when I last adjusted my pinion angle which needed to be set more to the negative side, it looked like the back of the car sat a little higher. Seeing where the spring perches are I guess that would make sense. I then did the hose mod to get it back down again and had to tweak the pinion angle once more.

I am sure that other shops would say something different. Depend on who you talk to anymore every shop has there own way. As long as it works at the end of the day.

Any other opinions or issue you guys see? If not I am going to get the scales back to the person I borrowed from. Thanks.

Kind of off topic but do you ever go to Mooresville or Zmax?

Been to Mooresville with the car once. Will get it to Zmax when I know I can put up the number I am looking for.
