What shop is this

That's the "Z Car Garage" in San Jose, CA. The shop owner, Rob, and the other guys are a great bunch. They specialize in Nissan, Datsun and Infinity cars for routine maintenance, repairs and high-performance mods. It's about an hour drive from where I live in Berkeley but I think it's worth it.

I started with the Hotchkis front bar and noticed an improvement with less roll. I added the rear after about 6 months and ran it with the softest setting (farthest hole to the edge). I didn't notice much difference with the rear bar and totally see why people skip it all together.

Well, I got the Hotchkiss sway bars installed front and rear with the rear bar on the middle setting so that we could go up or down on the stiffness. I haven't had time to do extensive testing yet but just on normal city and highway driving they feel good and are a definite improvement over the stock bars. The ride is a little firmer in general but without feeling harsh. The wheels' transient responses over the regularly-spaced concrete slab seams on some of our highways are better controlled now, with the tires seeming to maintain better contact with the road. The rear end is a little livelier now but is not overly unstable. I'll be able to evaluate this behaviour a little better when I find the time and the roads for doing some more testing. Overall, I think it was a good buy and one I wouldn't hesitate to do again Next on the program might be some firmer suspension, engine, transmission and differential bushings.
