Got the springs installed this morning. Pretty hard to overstate the immediate improvement. Axle wrap basically gone, back end doesn't try to go sideways when hitting bumps on a long corner on the freeway. Ultimately delivers what you would expect for spending $1000+ on the rear suspension.
After 50 miles of driving the hub to fender measurement is ~1.5" over stock, and 1" rake with my Eibachs on the front. I'll get some photos up soon, I feel like my SCAB looks just right now with the slight lift over the factory suspension.
A big shout-out goes to
@Rick@FreedomMotorsports , he patiently answered all my newbie questions and guided me to the right setup. Second time I've bought from him, it won't be my last!
