Hopefully I will get it installed here in the next couple of days.
Next autoX is the 17th. Only problem I see is that you can't run the front control arm bushings (I have the entire Whiteline kit I'm putting in.) Also, I will see what kind of stress is being put on the front bushing of the control arm.

i had this installed last november, along with poly bushes everywhere (energy suspension kit), heim end links front and rear, and whiteline bump steer. stock roll bars.
all together more direct steering feel at all speeds, easier to modulate the car in high speed (80 mph+) turns, no difference in nvh. while i cannot discern specifically since all mods went on the same time, this is a subtle difference.
I RETAINED STOCK CASTER!!.

It’s hard to tell because I did this and other suspension mods to go with it, i.e. coilovers, whiteline bushings.. etc. My lap times went down by 5 seconds @ NJMP

I was under the impression that too much caster actually slows the steering and creates more effort to turn. It's supposed to add high speed stability but slow turn in. I also understand that it dials in neg camber on the outside wheel which is a good thing. How much is too much on an Evo?

I installed the offset (added caster) bushings over the winter. First off... I had to notch the frame a healthy amount to get everything to fit properly. Second, the spacers didn't fit exactly right, but good enough to work. Just a warning, it wasn't the easiest install in the world (It was easier to notch with the steering rack removed, maybe it was just me and my VII).
I also installed the Whiteline Roll Center and Steering Feel kit as well as the AMS Rear Trailing Arm bushings, so I can't specifically speak of just the changes due to the PSSR. Ride quality isn't bad at all, unless I hit a really sharp bump, like a train track or pothole. Stability is incredible, if feels as if you always know what the front wheels are doing. I can brake hard while starting my turn in and have no ill effects at all. I also have done a day of drag racing with them and had no issue with wheel hop whatsoever.
I would recommend them, but caution that unless you really, really want added caster, consider going with the centered bushing.
