Coil over spring rates

[tmontague]

Deng, do you have a rear sway bar on your set up?

I'll be getting a corner balance at a local well known shop once everything is all set up. I'll have to ask FA about the rear spring rates but as far as I last rear they were fully custom.

Sadly, the Cusco's maxed out at 5k for the rear. I did want to step up my rears to 7k when I switch to Swift Springs. Heck, I might just buy some rear bilsteins, get them revalved for 9k springs and go that route. First I need a daily to replace my daily.

I pulled my rear bar off when I installed the coilovers, I didn't see a need for it with the stiffer rear springs.

Cusco can revalve. We ran 11k front and 14k rear with a Cusco setup on our 2012.

That makes so much sense. Less squat in the rear = more contact patch on the drive wheels. The More You Know *

Were you running the Competition Zero 3's with the monotubes? Cusco wouldn't allow me to go with stiffer springs on my lowly twin tube fixed dampening Street Zeros.

I was going to take my rear shocks to Feal, but they said they do not do revalves on Cusco. Plus with the Bilsteins, I can just drop them off and not have to worry about any downtime with the car. Which brings up another question I have about springs...I'll make a seperate thread about it.

Sounds like an awesome plan.

Yes, they were the Zero 3s, great stuff, worked really well.

Hard to go wrong with Bilstein, lots of options and great tuners out there. Guy Ankeny at FR-Sport can do wonders with those, as can Bret Norgaard at Yawsport (he is an ex Bilstein engineer).
