Well, the extended balljoints group buy has happened and my pair turned up this morning. Will try to get them in this week, and a new alignment done next week. With any luck I'll be able to get 3deg camber at the front instead of the 1.5 maximum I have now, and could be able to even out the tyre wear. Who knows, using more than the outer third of the tyre might help with corner grip too.

How do these compare to the Mazda version (N021-32-280A)?

Good link for swapping the tie rods http://revlimiter.net/blog/2011/03/tie-rod-end-swap/

Physically different, lower control arm balljoint is a bracket with balljoint attached, bolts through the tongue. The first post in the group buy thread has oem side by side with the extended version. Just pushes the wheel out a little more at the bottom.

Well, put them in this morning. To say they increase camber is an understatement lol. I forgot to take a before photo, but it was roughly 1.4deg negative camber, barely visible. After installing them, they look like this. I'd guess 3.5-4deg now maybe? Also introduced about half an inch of toe in, so alignment is hopefully gonna get done next week.

Install was pretty simple, or would be if I had done everything in the right order. Unbolted everything before trying to split the balljoint taper, so of course it took forever to knock that loose on the first one. Learned from my mistake, took 5 hits on the pickle fork with a small sledgehammer to break the second one free.

Put the car up in the air again and eyeballed the toe adjustment. Extended the tie rods 5 full turns, now it seems roughly straight, maybe still a mm or two inward. Good enough to get to Accurate Suspension for a proper alignment.

5 complete turns both sides would be more than 40mm total toe change!
Also how much thread engagement is left ?

Yep, it induced a ridiculous amount of toe in by pushing the hubs out a lot with the new balljoints. I've only eyeballed the toe now, it only has to get me to the alignment place half an hour away. As it was, the car wouldn't roll down a small slope without throttle because it scrubbed so much. Still enough thread for me not to worry. Right now it'd be set a lot longer than it will be after another degree of camber gets pulled out of it.

At what ride height was your max camber 1.5?

Trackphotos · Postby **Trackphotos** » Wed Mar 09, 2016 8:45 pm

Not particularly low, around 115mm at seams.

Alignment done. Front camber was about 4.3deg before having it done, so the balljoints increased it by 2.9deg. Now wound it back to 3deg front, 2.5deg rear, and zero toe all around. Feels responsive, especially compared to the wobbliness it had on the way to get it aligned.

Wing arrived. APR sent/CMA ordered the wrong risers, so standard height for now. Bit obnoxious, but should be worth a bit of time paired with a front splitter.

Do you need/want the risers?
It's a 3D wing so works best behind the roof where the air can flow down onto the middle section of the wing and straight at the differently angled side sections.
Lifting the 3D wings higher up into freer air just makes them work less efficiently.

Yeah, maybe not. Ordered them before I read about the difference between 2d and 3d wings. Will see.

Spent my day off on building a splitter. Starting with 15mm thick structural plywood, might build the monopan one further down the track. Just a little more work to do on this one, adding a couple of washers I had missed on the splitter brackets, mounting the brackets inside the wheel arches, and painting the lot to seal it against swelling.
