Try this: The Consummate Driver: How to Choose Spring Rates

Theres a bit more to it that just static load.

 

lol, all that damn math. Going to get started gathering all the info this week. Thanks for all the help so far.

 

Very cool calc! I didn't know about suspension frequency, good read.

I punched in my guesstimates and came up with 684.76, will use that as a starting point.

 

Are you sure thats right? Mine is near the 1400lb mark with a frequency of 2hz...

 

I went with 1.5hz and I don't have access to scales so my weight is probably not right, just an average of what I have seen others report (at 2hz I'm around 1200lb)

Also while I'm waiting I'm trying to get in contact with a racing buddy of mine to see if he still has his 4 corner scales.

 

So what about the 800 rate do you not like? I spoke with Jon at DBRods and he sells the kit with 800 iirc


ETA: he said for rcsb it's typically 750, 800 for ecsb, and 850 for cc

 

Well actually 800# isn't that bad - I forgot about the adjustable shocks

I had them at about 5 clicks from full hard for the canyon and forgot to turn them back, I went down to 11 clicks and it's much better now, more compliant over the bumps.

Initially they felt too cushy and I had to over compensate with the firmness of the shock, but I did find a happy-medium for daily driving that is comfortable.
(I just have to get over the fact that I'm not tubbed and will rub the inside of the fender occasionally)

I still want to play around with spring rates and length, but for now I'm sticking with 800#'s.

 

At 4" with these **** shocks I rub all the time and hate it. Jon said around 15 is a good medium setting. But I'll play around with the settings.

 

 

Sweet!!
