    Koni yellows. What's best spring combo?

    Guest-only advertisement. Register or Log In now!
    Thinking about going with the koni yellows and some sort of spring. Not sure which spring would be best with the yellows? I would like to go this route over coil overs because I have always have had great luck with konis vs coilovers. Any insight would be great.


    Thanks

    It looks like Koni's upcoming sets for STR.T and Sports include H&R springs with the dampers, whether those are specially made springs or the standard H&R Sport spring I don't know. They should be available next month.

    Swift Springs have a higher rate than most of the Eibach/Cobb/Mountune springs, so that might be worth looking into.

    I will start with the stock coils..

    And then maybe move to the Eibach sportlines.Then, if I still think there is something to gain (unlikely), I will install a set of H&R supersports. The ultimate choice really depends on the way the car is used and how it is prepared for its purpose.

    +1 for the swift springs.

    I have had Koni Yellows w/ Swift springs on Multiple previous cars and they always work seamlessly together. (350z, 370z, C5 Z06, Stealth RT/TT.)

    As a matter of fact it is my plan for the FiST as well. Swift springs are probably the most widely used springs for track time. Some cars even replace coil over springs with swift springs because of their reliability and performance. There is a lot of research that gets done on Swift springs before they get produced. They also have great customer service as well, and can even help you find a set that matches your means if you decide to go Coils w/ Swift springs. Never had a bad experience w/ their products or their customer service

    Stay on stock unless you want to be lower. I'm running koni yellows on stock springs. The valving on the yellows controls the springs so well and honestly your not going to feel a difference in stiffness due to how low of a change the other springs are.

    I'm lost on this. I'm wanting to go lower. I do good amount of autocross and I'm looking to improve from the stock setup in performance. I'm not picky about the ride. I'm going with a 15 inch wheel and that would look horrible at stock height.

    The more reading I do the more I get confused. I was happy last year for most part running stock. I'm gonna end up In stx this year and I'm not concerned about how place. What I'm looking for is reduced wheel gap with new 15 inch setup. Also looking to get rid of some of the 3 wheeling. Since everyone says the stock struts are too stiff maybe I'm better off keeping them and just going with one of the springs that are just little stiffer. I would like to keep close to way is without screwing things up too much.

    I'm currently running Koni yellows in the rear with the stock springs and a Hotchkis sway bar. The Konis are set at ~1/2 turn from full FIRM and work well.

    In the next week or two, I plan on installing Swift springs and Konis in front. Most posts that I've read recommend ~1/2 turn from full SOFT for the front. My inclination (based on nothing to be honest) is to run 'em a little firmer than that in front, but this is also my daily driver, so I don't want to go much firmer than stock. Thoughts?
