[QUOTE="zayne2427, post: 718343, member: 999"] 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 [/QUOTE]
