The Hotchkis does introduce some lower speed understeer on street tires (attacking sharp corners at < 40 mph for example). Camber corrects the issue but unfortunately you can't do that in stock class for our cars.

I tried the Eibach front bar for a few events last year. I'm running 285 RE-11s all around. The Eibach bar on the stiffest setting made the rear very squirrelly...lots of oversteer. I went back to the stock bar and have been happier and faster. Really, it's driver preference, most of us here can't drive the car to its capable limits and Whiteline, Eibach, or other won't "turn" us into a pro.

The Eibach is much thicker than I first thought, thanks for the numbers.

The spring rates for the Hotchkis rear are:

930, 1160, 1490 lbs/in (based on the 28.5mm bar)
+70, 110, 170% stiffer than stock 370Z

The Eibach rear sounds crazy stiff if their numbers are accurate.

I think the Eibach bars are meant to match with their springs as well. Not sure though.

going from 25mm to 27mm

That's if they're made of the same alloy using the same process and are both tubular or solid.

That matrix doesn't say anything about going from tubular to solid or vice versa.
