Thread: RR spring rate

  1. #1

    Default RR spring rate

    When swapping from a 200 RR to a 250 RR. What should you expect?

    The RR will have more authority over the rest of the car. When decelerating, car will be tighter when accelerating, car will be looser, in general.

    250 RR seems stiff. We started the year on 200, then 175 and now down to a 150. Have heard of guys running 16" 100# springs on there 2 link cars. I think they are trying to coil bind the rr?

    150 sounds insane soft. Probably work ok on a stop and go track.

    I see thru this thread that someone is running a 16" spring,, does anyone know who makes those?? My normal Interga springs do not have a 16".. Looking for 16" in 100,125,and 150.

    AFCO, Eibach, and Hyperco make 125 and 150 16", Eibach has a 100 in 16", this is just off of what Performance bodies carries.
