Bob, sorry to jump in , but you speak of what i need to learn.
I am planning a job to a chevy s-10.maybe mid to late eighties.I have a 350 with a 2 speed glide .I want to lower the truck safely but it must still be able to support the heavy motor. I'm looking at maybe lowering it all the way around ,fill in that ugly curve halfway down , maybe some ground effects or the like.
If I understand correctly when the car is on the ground the top top and bottom ball joint should be perpendicular with the spring installed?
would a 1"shorter spring drop this set up 4 inches??or would the motor do that??would i need a proportionately shorter shock ?
this vehicle would be a sunday driver, but with a hundred mph. first gear, i want it driveable.
any information you can provide, or even a link related to this topic , would be greatly appreciated. mike
