Exactly....soft in the rear end, so the car "squats" on launch and loose in the front end, so the springs extend and it comes up when you nail it. If it's too stiff all the way around, you get neither of these and the car does nothing but buff ash vault.DocG2828 said:My best guess would be you want soft suspension in the back so the weight will transfer more.
Just think about how much better you could have done with softer springs.Jackie Chan said:it all depends on the dynamics of the suspension. weight transfer to the extreme doesnt always mean better 60's. I have cut mid 1.8s on street tires in my cobra with a slammed susp.
it's more about the shocks, the rear springs don't have too much of a difference since it's a live axle in the back, some rear springs run progressivly lower than stock springs, up to around 300lbGearbanger 101 said:Just think about how much better you could have done with softer springs.

Gearbanger 101 said:Contrary to popular belief, going with a set of LCA's don't necessarily translate to better 60ft times. Truth be told, LCA's are actually going to hurt you in the first 60ft on street tires. Great for use on a car running a stiff chassis and slicks, but not so great on your average stocker.
The problem being, is that there is next to no flex because of their rigid construction and hard durometer rubber, urethane or solid bushings. This is great for consistency and getting all of the power to the pavement, but getting all of that power to the pavement right off the bat isn’t always a good thing. Unfortunately the power soaking stock arms that are often responsible for unpredictable 60ft times are also great for absorbing that initial "shock" that's realized through the rear end when one comes off the line and often breaks the tires loose. Without the springy stock arms in place to do this, the forgiveness that you would normally get, isn’t going to be there.
Bottom line…..if you’re going to build your rear suspension for drag racing, then actually build it to drag race. Many have tried the multi purpose route, or putting in the odd part here and there because some buddy of theirs said it would help, but in the end the only real winners at the strip are going to be the ones that were purpose built to do just that.
