I think they are very similar in construction, w/ the exception of the bushings used. Kartboy utilizes a hardened poly bushing, Perrin utilizes a metal spherical bushing. The spherical bushing should outperform the poly bushing- if it holds up (not affected by dirt, road grime etc.). Kartboy actually had a drop link w/ spherical bushings (quite a while back), but pulled it due to bearing wear (dirt,grime the culprit). Perrin evidently has done quite a bit of testing (rally, rallx) and thinks the design of their bushing will hold up.

I picked up a set of the "original" Kartboy spherical bearing endlinks used off the board and found them to be a bit noisey as well. Very effective but noisey......I have since moved on to the "new" style Kartboy links.

are you talking about the droplink insets that replace the rubber bushings in the stock endlinks? if so, i have a set of the kartboys. they provided a noticible improvement in the responsiveness of the rear sway bar. however, the left one keeps squeaking; i've been having to lubricate it every few months with silicone grease to quiet it down.

They are talking about the "new" metal links- the entire link. I believe (might check w/ them to be sure) they have also quit the inserts. I believe they were having fitment problems w/ some links- other links they fit fine, possibly a too large of tolerance range in the oe links.

BTW- I also have the Kartboy endlinks and mine have worked fine- no fitment, squeaking issues.

Evidently there is Subaru upgraded (Group N) bushing for the sway link- I've seen it posted on a vendors site a while back (maybe RalliSpec's older site), I'll try to chase that down.

I have the Kartboy solid endlinks with the poly bushings along with the MRT adjustably rear swaybar set on 22mm. They've been on for a couple months. I absolutely love this set up, the car is on rails:-) At fist I ran it with the stock links for a week, then got the Kartboys. It was a very noticable difference. There was a big difference with just adding the bar. Adding the Kartboys made it feel like I put an even larger bar on.

The new Kartboy endlinks are great because they restore proper suspension geometry on lowered subys. This is because they are shorter in length. They also give more clearance to the fuel filler neck which eliminates the annoying thunking you get with the stock links and the whitelines.

I broke my whitelines.
I've never used the Perrin.
I don't think there is a whole lot more to improve over the kartboy links.

I have an entirely aftermarket suspension that is well complimented by the kartboys.
