coil over spring rate?

ciara · 11-24-2003, 06:40 AM

I have an 84 gt hatchback with a 351w. It is a drag only car and I am wanting to switch over to coil overs in the front. What spring rate should I get for this.

With my R-block based 308, I've got 150# springs up front. Now my car weighs 2900# with me in it and is VERY nearly split at 50/50 (I know, I'm working on it). With the heavier 351 up front, I think you'll find most places will recommend something in the 200-225# range. The guys at UPR really know what they're doing with the coil-overs, so you could call there and get their input.

At D&D the products are great, but it took three sets of springs, at my cost before they sent the right ones. They seem knowledgeable on the phone. But it cost me three times of giveing them the same info every time, and me paying out the axx for springs, that are considerably less at JEGs, And I could have guessed as good as they did.
