Need a rear spring recommendation.

guys,

Can you ball park me a spring rate for the coil overs on the rear of my car?

87 Mustang hatch. Backhalved, 14x32s, 4 link, BBF and a glide...

130# ish...........

Thanks.

12 or 14" long?

I'm running a QA1 single adjustable. Recommended ride height is between 13.75 and 14.25. So I'm guessing 14" spring?

14"

With the shocks you said you had and the ride height required they are for a 12" spring. The 13.75 ---14.25 should be from the bolt hole to bolt hole dimension so you have adeqate compression and extension without bottoming out the shock or topping it out.

12" spring Mr Bozelle.

Thanks Travis. I'll double check the part number on the shocks next time I go to the garage.

Anyone use the springs from ART? Or is there someplace better? They'll be riding on some single adjustables so I don't need anything fancy, just don't want to waste money on junk.

People call them junky but I have great luck with QA1. Oh and the fastest DR car in the country uses them too.

John,

I have ran Hypercoils for years and had really good luck with them. Some of the cheaper springs seem to bow in the middle and rub the shock itself after about a year or so of setting or running. Not saying the ART springs are some of them because I don't know for sure 100%.

Thanks Travis.

I have 80# in mine....ladder bar car.

we run 110#'s. 12"

120-130lbs sounds like a decent starting point to me. I got 130lb springs for my Maverick & I'm expecting it to be in the 2900-3000lb range. But I also have 80, 100, 110, & 150 pound springs on the shelf to play with.
