    what are the specs on the coil overs i.e.. the extended and collapsed lengths that you are using in your kit? and whats the stroke length?

    Why didn't kit come with Qa1 coil spring opposed to Eibach? What are the differences between the two springs in terms of ride quality and performance?

    QA1's only go as high as 350 ppi, in the 2.5" diameter. Eibach goes higher.

    Actually, we are both correct. However, the spring rate goes by size. If XII is using a 14" linear spring, then they are limited to a 350 ppi. With the 12" they are limited to a 600 ppi. Eibach has up to 650 ppi for a 2.5" x 14" linear spring.

    I should have been more clear in my previous post, as I was already assuming that they are using the 14" length spring, when in fact I actually don't knkw the length they are using at all.
