Re: steering stabilizers
They can considerably help the ride with larger tires. But you should keep in mind that a steering stabilizer is like a band aid. It doesn't solve the problem, just covers it up. I'd run your existing one with the new tires, get the suspension as accurate as possible, THEN throw on the stabilizer.
