afco spring question
OK, so the minitub is getting closer to being done, and I am planning on installing the afco 2 5/8" ID springs. My question is which one??? According to MOOG our cars factory have 107 in/lb rate, free length of like 15.5 and 10" installed.
I know there are several guys on here running these style springs, but, after searching I couldn't find where anyone said what length and spring rate they had.

Re: afco spring question
150 is too much IMO, 120-130 will allow for some stored energy. You only need enough spring to hold the car up or you miss out on what your rear shocks are capable of...of course if your running monore matic`s on the rear then I guess 150 is just fine.
