Coilover spring rate

[Squeegee]

I'm going to weigh my 80 and get the f/r weight bias today so I can get an idea of what springs to run. It seems like everybody who runs coilovers has to go through a long process of tuning and they end up getting like 4 sets of springs, I'd kinda like to avoid that.

For those who are running front coilovers, whats your spring rate/ lengths. Im going to be running a 2.0x12 with a 3 link.

Did you end up finding spring rates for your truck?

So for future reference, I'm on 275/350 springs on 14" coilovers

I got my 12” coilovers from accutune. I’m running a 250/350 with 7/8” of preload. The coilovers are mounted at a 10ish degreesish rake and the front rode a little high with the prescribed 1 7/8” of preload. I talked to accutune and they said that I should move down to a 200/350 so that I can achieve their desired preload amount and keep the ride height the same… I think that all made sense

So very much of this depends on vehicle weight at the front axle and the angle of coilovers as you mentioned. Mine are raked back a little as well, but I weighed in at 3200 on the front axle. Accutune sure helped me and I was fortunate enough to have it right on the money the first time along with the valving. I was doing mine as your pics were coming through, so I had a nice reference point haha

Good info guys. I’m working on my 100 series sas now. I weighed in at 6k lbs before I cut everything off. Factory bumper with a winch. I’ll prob call Accutune and see what they say.
