koni spa1 rear drag shocks coilover
 

hey guys i have a 4 link back half and im wanting to get some opinons on shock settings. on the lauch it hits the tires hard then immediatly settles down.. some said to try adj the shock. but i dont know if i should stiffen the ext and soften the compression or viseversa. its ran 11.17 at 120 and i think it will go tens. the 60 ft is way off for a tubbed vehicle at 1.668. with a 32" tire and 5.67 gear. its trapping way better and pulling more mph than with the 4.56. im comming through the traps a little low still about 7400..
its a 355 motor and 3165 lbs. with a 5500 converter. two step is set to 4000 rpm. thanks guys i have to race points and dont get many shots at my chages.

what is the front end doing? are you extending your shocks all the way out and this is what is causing you to spin? is it spinning when the front settles back down? pictures of the launch would help

that was on spray with the 4.56 gear but its doing the same thing their. it hits the tire starts to lift the front then immedatly settles down hard. the vid shows no signs of spinning. but it does show the tire wrinkle then quit then start again. ive played with pressure. but not shock settings.
i would think on motor it should run high 10s if i can get it to 60 ft in the 1.5s wich i think is still kinda crappy.

right now on the vid the truck seems to start to extend in the front pulls the tire about 1" and it just drops like all the weight in the rear shifted forward again.
