    GC spring rate? not the norm

    Alright so I have a guy close to me that I recently met who has the conversion kit on Billy sports which is the way I'm going... Well after riding in his car I felt like it was a little bit too soft. He didn't know his rates so after I checked the springs I found they were 388F and 475R.

    If I want something a little stiffer (it's my DD) what would be a good recommendation? I'm not sure if going up to 400 and 550/600 is going to be what I'm looking for as I'm not sure if that would make a slight or significant difference. Thanks for yalls input ahead of time!

    Those front springs are plenty stiff, but the rears are too soft. With 388 front springs the rears should be somewhere around 700. Since H&R Race springs are 315/570 I'd think that you wouldn't want to go much higher on a DD.
    The car makes it possible, but the driver makes it happen.

      GC doesn't have Eibach make any 388 springs.

      Let me know the numbers on the spring.

      Was the kit sold for Bilsteins? Perhaps "GC150.64.66"? If so, that is a reasonable combination for Bilsteins. If you remember that the car doesn't just see the spring for the spring rate. The car sees the combination of spring rate, bump stop spring rate, tire sidewall spring rate, front mount spring rate and spring offset, cumulatively as "THE SPRING RATE"


      If you have questions you can call GC.

        I believe the number is 150.64.68, the last number could possibly be a 6 but from the picture I took it appears to be an 8. don't have the money just yet for the conversion kit but I'm just doing a little searching around. What are the rates for the kit sold for the bilsteins? I'm thinking that may be what he had but I'd like something just slightly more firm. Thanks for the help
