Coupe don`t hook

[Dollar]

Hey i have a spining problem that i have not fixed yet. I have a 86 coupe with 90-10 4cly. springs front and back and HPM adjustible upper and lowers. The best 60 ft. i have gotten is 1.63 this is what i did i could have made a mistake. When i put the upper and lowers on i made the lowers a little bit longer then stock ones and made the uppers a little shorter. I don`t know how to set opinion angle so i could be way off. So can any one tell me the beat way to set opinion angle or any advise will do Thanks?

your p/a really won't cause a great loss in traction...only a little hp loss through the wasted energy at the u-joint. generally set p/a at -4 with stock rubber bushings, -3 with urethane bushings, and -2 with rod end type arms. i always set my angle finder on the rear of housing.

thanks buddy i will try that but there is one more ? do all have to be on jack stans or it can be done on a lift?

crap..sorry it took so long to reply. axle must be at ride height. you can use jack stands but..you must first maintain the same frame to axle measurement and measure your frame angle front to rear at ride height to make corrections when only rear of car is up. make any sence? good luck.
