I'm looking into buying a set of D2 coilovers for my EJ coupe and I've come across a set here on HT for a good price, but the guy custom ordered spring rates for them and got a higher rate (12k) on the rear than on the front (10k). My question is, can I switch these springs between front and back to make the front a 12k and the rear a 10k or are the springs not the same between front and rear? I've heard that most of the time, with a coilover setup, the progressive rate springs are ditched in favor of a constant rate spring, so I thought that maybe they were interchangeable.

I double-posted this here to see if I could get some more answers and hopefully get someone that has a set of these to look at this.

 

Never do that with coilovers each shock is designed for that specific spring and spring rate. if you change it you could be in the market for another set of coilovers.

 

Decent info, but they will usually only do that on a set of coilovers that are very far out of the original spec. The normal spec on these are 11k fronts and I believe 5 or 7k rears. This means the rear may have been revalved for the 12k spring, but putting a 10k spring on it should be less stress than what would've been on it and the fronts are only off by 1k.
