Double stack ??

I know the slider does work better with the longer 700lb on the bottom and the shorter 400lb on the top, thats what AFCO seems to sell everyone, BUT that set up only works only on the stickyer tracks, not the slick and causes a push from the apex out as the 700 takes over too soon for the slick. Those springs are on my car right now so I can't measure them exactly but I think it is like a 4" or 5" 400lb and an 8" 700lb from AFCO. I have gotten the AFCO to slide and work well with the shorter 400lb on the bottom in th past, but it is right at the bottom of the shock body and you need to make sure the longer side of the nylon slider is pointed up.

The last 2 years on slick I use a Hypercoil 7" 400lb on the bottom and a Hypercoil 6" 700lb on the top as it lets the slider have more contact with the shock body than the AFCO set up. Always watch those dang lock rings as they can and do move.

I have worked on this stuff a ton,so ill give you my experence,think about it if its just the middle i would adjust the lock nut some,this is whats happening,your car is going in the corner great but as soon as you pick the gas up its real free until it gets back on the big spring and then drives the car forward but by then the car has rotated to much and it shoves u to the infield,the fix,shock,adjust the lock nut,or get off the stacked setup and go to a standard spring,the stacked setup is not for all tracks and your shock is a huge factor in this setup,good luck,also i would just work on the rf first,just my 2 cents

Decrease your stack nut distance...Pull some rebound out of RF shock...You need your car on that stiffer spring sooner!
