Can we add a spring thread to the FAQ section

I would like to see a part of the FAQ to address the height of our cars with all the different springs. As an observation, i have noticed almost everyone runs different springs, I have two different makes of springs on my car... and with my LCA's, my car is even lower in the rear than someone elses would be.... soooo

basically a description of your spring setup, including anything suspension related that would change ride height, such as adjustable lower control arms etc.. Would also be a good point to include whether you used isolators, no isolators or just the upper or lower isolator.

IMO, this would save a lot of picture threads for springs, questions on them etc......and be a quick reference for people shopping around for springs trying to ge that "certain" look they are going for..... you could say find a set of rears that sit the way you want and fronts or a pair that sit how you want.......what do you guys think?????/

I'll put anything in there that everyone wants. As for this one people could post spring info but there are many factors for ride height. Isolators, ball joints, K-members, etc. I actually had to raise my car up front with 1/2 inch spring spacers.
i have been looking for springs spacers for the rear of my car..... where'd you find them. link please....

as far as ride height that is why i noted any ride height altering modification.... I just thought this would be a great reference.

good info..... but most people would relate better to a pic i would think? could be wrong though.....

i'll start with the pics, i have had four spring setups so far on the car......

mach 1

i was thinking about pics but its kind of hard since everyones car is a bit different, two people can have the same exact springs and look different

i have mach-1 springs on my car
I can add that table posted above to the FAQ sticky. Pictures are tough like mentioned. Again more factors come into play-wheel size, tire size, C/C settings, etc. When I compare my car to Roger's his is slammed compared to mine with roughly the same springs.
