According to the FAQ they should be really good. I love canucks but with an extra 100lb rate in the back those should be amazing. The 15lbs in the front probably wont notice. They are way better the eibachs.

Wouldnt these be a little too stiff and create a rough ride? I dont know much about suspension

These are probably the Suspension Tech springs listed in the FAQ, just being distributed by someone else. Since they don't actually list them as ST springs, who knows.

A 400lb linear rate spring is a bit overkill for a FWD street car, even when paired with a 200lb front spring. Based on my past research, I don't think they know the rates of their springs (see the quoted FAQ portion, where there is no definitive answer as to what the rates are, and now there is a third answer), and based on the past history of Suspension Tech, I doubt there is any quality control to ensure they're whatever rate to begin with. You're getting exactly what you pay for with that listing.

Sorry didn't know anyone made progressive springs for our cars. I was looking for a manufacturer for a while. I guess it's impossible to get a set not since almost every manufacturer on that list except for APEX 1.0 Drop, Canuck 1.7/1.6, and Springtech make springs for our cars.

Yup. Really the only quality springs available now are the Canucks, unless you find a random set of Eibachs on ebay or something. They do show up from time to time, but normally it's a seller listing something they don't actually have in stock, and when they order it for a drop ship, they end up telling you they don't have it and refunding your money.
