Finally got these installed. All I can say is wow. What a nice piece of kit!
I was expecting a seriously harsh ride after this because of the heim joints, but I actually think that the car feels smoother over bumps, and its less noisy in the rear. Going over train tracks is no problem.
They were somewhat of a pain to install, mostly because of the long bolt that goes through the hub. Ever car that has parallel links has this problem. The bolt is so long and exposed that it inevitably seizes and nothing except the hammer of thor will budge it. I recently bought a spare sub frame and had to resort to a 10 lb sledge swung with everything I had (thor was busy) just to get the thing to move a few mm so I could cut it. The end of the bolt doubled in thickness from mushrooming.
To make matters worse, In North America you can not get a gtir bolt. They just don't have them. My go to dealer told me that Japan shows them as unavailable. After some research I settled on a Nissan Axxess bolt. The Axxess is a van that was sold in NA that came with the GTIR attessa (but with the ka24de). Strangely enough the AWD Axxess doesn't use a long parallel bolt, it uses two. The FWD Axxess however, uses a long bolt, and works as a replacement for the GTIR bolt although it is about 1 cm longer.
Solved right? WRONG. I bought the last one in Canada. That's right, one, not two. So blah blah, panic panic, research, grumble...anyway I found:
The Subaru STI uses a parrallel link setup and the bolt is almost the same just a little long(2 cm or so. The best part is they are only like 12 bucks a peice not 40 like the nissan one, and STIs will be around for much longer than our old Nissans so it is a good solution.
After snapping one of the old bolts, the other one actually broke loose with the help of a 5 foot breaker bar.
Install by setting the front arms to the proper length (I lined mine up to the stock arms), and then adjust the rear arms to set the toe. I plan on eliminating the eccentric bolt on the rear arm, but for now I set it all the way out to reduce the amount of thread that would be exposed on the heim joint.
On install, put some 14mm washers on the end of the bolt to take up the extra bolt length. Also remember to bath everything in Anti Seize.
That's it, put everything back together and enjoy!
On my coilovers these still have a fair bit of clearance at the front arms at full droop. I suspect that on stock suspension they would be getting close however due to lack of bend that the stock arms have.
