so i was checking out different spring rates and comparing the FMS to stock mach 1 and bullitts and noticed the main difference in mach 1 and FMS C's is the rear in the mach is linear and rear in C's are progressive.

so whats the difference on the street? looks like the mach 1 and C's would be very comparible for a street car.

edit #2 - the lower the number the softer the spring? or vice versa

no...the front is higher than the rear. and i want it leveled out. i have always liked the FMS C springs and was looking at the spring rates and see the Mach 1's are very close to C's

i saw wicks stang with the B springs and it looked really good...so i think the C's will tuck 17" rims a little more...plus look better while im on 16's.

Here is a picture of the FMS C springs on my 88 before they were taken off. I think the give just the right stance for 17" rims.

i agree completely....now if i was to go with the Mach 1's....how would the rear compare. since one is linear and one is progressive.

also Ed - did you cut your C's or remove isolators or anything? thats the look im after
