Has anybody checked whether the latest Perrin 2011-2014 STI Subaru ALK 3" fits the 
Evo platform?
It is described as 3" which is the identical measurement on the Evo LCA and it even looks the same as the old Evo part ...

Whether it still comes with the proper spacers is another story ...

Found this from the horse's mouth on IWSTI.com:
Re: Anti Lift Kit for STi 2011 Sedan
I think there is a misconception about noise. I have had these (ones using the bearings) on 3 different personal cars (75K-ish miles between them)and NEVER had them come loose, or rattle ever (currently going on 4 years on my 08 STI with). The only time its loud is on big potholes. I think this is the case with most all our customers that live where there is no salt on the road. But we do know that it has happened on a few guys cars here and there.
I talked to Chris here who deals with our warranty on these kinds of things and he said it very rare that someone calls with a PSRS being loose. He couldn't remember the last time he sold a bearing to a PSRS customer. A couple weeks ago one of our track day customers brought by a couple pairs to replace bearings in them. Both had 2 years each of track abuse (roughly 20 track days each on them). They were loose, but not to the point of failure, just caused a little rattle. Because he was a returning customer we sold him new bearings and a very fair price. With that said from our chairs its not common to have them come loose and we really don't see much in the way of problems.
If you do have problems, and they are under warranty, then we will take care of you. If they are out of warranty and you are somewhat nice to us, we will get you a good deal on new bearings. We also can get customers SS bearings for a little more additional cost.
This part is a racecar type part that works very well for street use. With that said its not going to last 100k miles on the car (i have seen the OEM parts fail at 40K BTW). Also we don't expect every one of our customers to buy this part. And now that the 2011 STI has the same part as used in the EVO, we know there is even less potential customers interested. But in the EVO world we sell the crap out of these things and they love them (same part as the 2011 STI). I see two kinds of potential customers for the 2011 STI.
-The track day guy or aggressive street driver, who wants to get rid of the rubber and may want the optional added castor. This customer is a great potential customer for our PSRS.
- The other guy drives his car on the street 99% of the time and doesn't care about the removal of rubber and wants added castor. I hate to say stick with the stock part until there is a urethane version with added Castor. This potential customer is one that isn't interested in our PSRS.
We really think the bigger benefit is the removal of the rubber from the bushing and that is what customers are going to notice over the castor.
Not sure what the disclaimer has to do with dust boots or anything. But i can tell you that the simple $2 dust boost doesn't cut it. We have used these in the past and can be added to any of our PSRS's. The problem is they fail. Then you have a false sense of protection and may not look at your PSRS bearings ever.
If you live where the roads are salted or there is high corrosion going on, nothing lasts forever, especially those rubber boots. The bearings we use on our PSRS will stay nice and tight for a long time and only in the high corrosion areas might you see a shortened life span. But from what we see, they last plenty long enough. The best part is to fix them, its rather cheap and easy to do with out messing up the alignment.
I hope that helps answer some of the question and thoughts about our part. If you have more questions or comments, shoot them our way!

I have installed my Whiteline Anti-Lift kit and there is no need to dent anything. However I noticed that while installing, the bushing height was shorter than the oem bushing. Therefore when I was tightening the bolt it bent upward a bit of the subframe until that portion met with the bottom of the bushing sleeve.
The instructions did not say anything about adding a washer so I just left it and then torqued the bolt to spec.

reporting back after installing the Whiteline unit and hitting the track.
Not much additional caster at all
think ended @ 4.4 - 4.5 degrees total (small increase over factory which I believe is 4.1 degrees).
It did indeed eat away at the fender liner so be warned.
Car felt a difference however I also had carbon drive shaft / slightly more aggressive alignment / reduction of front spacers by 7 mm and these bushings all done at same time.
Now running:
Front:
camber: -3.5deg
toe out 0.02 (mins)
caster 4.5deg
rear:
camber: -2.4 deg
toe - neutral (0)
turn in was better, I just need more practice at the track now

Stock is 3.9 degrees, but I imagine you weren't at OEM rake. Between getting closer to stock rake and the Whiteline spherical bushing, I picked up 0.7 degree of caster. Now at 4.3 degrees.

raising from the dead - is the above the equivalent part from superpro? was looking just to move the wheel position but added caster and firmer bushings are obviously a bonus - but as far as antilift goes - terms are a little confusing. with this bushing installed, will the front end dive less?

With the PSRS, if you install the taller spacer up top, you get anti-anti lift and decreased anti dive, as well as probably a tiny bit of additional caster even in the non-offset version.
So you actually get a bit more dive under braking if you use the anti anti-lift feature.
I don't see the Superpro kit having spacers to adjust, so I would expect it to just add caster similar to the offset PSRS and keep toe more stable under suspension loading.

What are you trying to do? Just move the front wheels forward in the wheel well? I am running 17x8 +35 wheels with drag radials and running into a small clearance issue with the fender
liner and where the side skirt wraps inward into the wheel well when I turn full lock. I'm only considering this super pro kit to move the wheel forward slightly.
Anyone know exactly how far forward it moves the wheel?
