Ohlins R&T (BMZ MN01)
Ground Control street camber plates
stock sway bars

You might be able to get away with just replacing the springs with something softer, but I've read that the valving will be off on the dampers if you change drastically from the current spring rate. Measure the spring perch, swift should have something that fits. https://www.swiftsprings.com/product...lover-springs/

I'm pretty sure this is a 7" spring.

Not to go too far off topic, but why ground control? I believe Vorschlag is the only camber plate to use a 3/4" spherical ball mount, which is much more stout than anything else available. Just my 0.02.
