Wrong KCA400M is listed for the EVO X and it only adds 0.5 caster where as the perrin added 3.0 so no it's not nearly the same.

VIII/IX/X Are all the same, IIRC. But that sure is a reduction in caster.

Yeah you definently don't get the same amount of caster with the Whiteline, but you do get more then stock. I DD the car and plan on using it to get my instructers licence. I don't need to extract every bit of performance out of the car.

The PSRS does not add 3° of caster; it was supposed to be roughly 1.5°. Still more than the Whiteline kit, though.

Perrin's EvoM thread

The OEM bushings did allow flex for a compliant ride hence the reasoning behind the solid mounted spherical in both kits. Before I put in the Whiteline kit I was going back and forth between the two brands. I ended up with the Whiteline because I didn't want to have to cut up my subframe and I wanted the extra protection afforded by the boots.

My PSRS added exactly 1.5* on one side and 1.7* on the other, and I now have equal caster since it was off a bit stock. It was pretty cool to see the finished alignment with perfectly even toe/camber/caster..

This.

Although I have been hoping to have more selections for our car.
