I am close to having a replacement rear spring from Eibach picked out. With the wide selection they have, a custom wind is not required (custom = more cost). My rapidly upcoming wedding and customers airplane and engine requireing reassembly has slowed me up, but I should have the spring speced out in a week or so. Eibach was very helpful in supplying the formulas and springs they stock. The next issue will be finding a shock with increased damping to match, Insight a VERY short shock. I do not plan to change the fronts, at least initially. The rears are way unbalanced, and the fronts may be just fine as is. Loading the car adds far more to rear loading anyway. It's true this will increase oversteer, but I like a FWD with that, nice change from understeer (if you know how to drive, lol). This can be balanced somewhat with replacement of front stabilizer bar bushings with hard urethane, gives quicker increase in roll resistance. Again, I am intrested in suspension load ability for normal driving, not full race handling. I am pretty happy with the basic handling considering the cars purpose.
