Rear Suspension Video

springs look as if they are "almost" totally stationary little to no compression or expansion at all on the initial launch leads me to believe they are too stiff--- look at the video if you can put it in "slow motion" things hapenning to fast on the normal speed hard to see whats really going on in 1-2 seconds--I would put ladder bars all the way up to top hole to preload the chassis just to see if it likes it--- if it does then tweak the shocks a bit a little at a time to see what happens if it likes that then go to changing the springs go from the softest or the firmest all the way to the extreme opposite--- I would only do maybe 100-150 foot long plus squirts to see your results--- dont waste time doing anything longer you just want to get the car to launch who cares what it does in the 1/8 or 1/4 work on that later--- just remember for every .01 in the 60 foot usually means .02 in the 1/4---you are not looking for subtle differences now you want radical changes then you can fine tune what ever it is you are trying to do by changing shocks, locating points or spring rates and even rear tire pressure to---- you are not gonna solve this in 2 minutes unless you get lucky and hit the right combo right away----my 2 cents ---FED387
