I need some guidance on proper coil springs. I'm building a Cuda, with a Busa. Ordering Fox 2.0. I weigh approx 185lbs. Any suggestions would be greatly appreciated.
Thanks
Tony
ps. I will be using 12" in rear and 8.5 in front

straight 2.0's would work on there own but if you don't order coil assist 2.0's you won't be able to put coils on them.
-
Sorry bout the lack of info. The shocks are coil over 2.0's w remote reservoirs.

FOA shocks has a calculator on his site.

So does swayaway and a few other places. We cannot stress enough the importnce of getting accurate sprung weights and accurate angles to use in calcs.

Garbage in garbage out. Thats how you end up with a shelf of "wrong" coil springs. Good news MasterFabr is looking for springs. rofl

My experience,for me anyway, is that they wil be a bit soft using the swayaway calc. Yup,need a bit stiffer rears. LOL!!! Sort of like shock valving,everyone needs/wants something different. Calculators will get you pretty damn close but from there it's up to you.

I got a shop full of them...Lots of nice ATV STUFF...But too small for you rofl

Ya mean midget stuff? ;D ;D ;D ;D

Get a pair of used springs as close to what the calculator says just to measure with. You only want a single rate. It doesn't matter if they are long enough, just put a spacer in. If you want a 12" shock to compress 5" and it compresses only 4" with a 100lb spring, then you need a 80lb spring rate. 4" x 100lbs per inch = 400lbs of load. So an 80 lb per inch will give you your 400lbs of load at 5" compression. If dual rate, decide how much harder you want the second rate than the first. If you want it double, you would need 2 160lb per inch springs to get an 80lb initial and 160 lb per inch secondary rate.
