I got online last night and took advantage of a few labor day sales. I ordered all new Fox 2.0 remote res coilovers with DSC adjusters and Fox bump stops and cans. Here are my current measurements using sway away 16'' coil overs. I would like my belly around 1" lower than the current . Just have to figure out and order correct springs now. Thanks for the help
The measurements below are using 14" upper springs and 16" lower springs. i'll be going back with 16 over 18's
Line 1 is the current spring rates
Line 2 is the measurement of combined spring length at full droop with zero preload including the dual rate slider
Line 3 is the combined spring length measurements at ride height
Line 5 is the amount of shaft showing at current ride height measuring from top of lower spring retainer which is 1 1/4" thick
Line 6-7 are the upper and lower spring length measurements with weight on them measured individually not including the dual rate slider

Based on the spring rate calculator chart mccutler has posted in the past the 150/200 =86 and 125/200=77 combined with the amout the springs settled with weight i believe the below calculations determine my corner weights.....

Front Left 86 x 7.5 = 645 lbs
Front right 86 x 8.125 = 757.875 lbs
Rear Left 77 x 4.625 = 356.125 lbs
Rear Right 77 x 4.5 = 346.5 lbs

Re: Spring rates help again

Everything is measured using a lift to get full droop and setting the top adjuster at barely touching the upper spring so zero preload
