Finally went for a drive (to pick up some lunch at least) in the FRS today, did not crash.

First reaction:.

The only way to describe the handling without overusing the term "solid" is that before it felt like a good coil spring mattress. Now it feels like a good memory foam mattress. Didn't drive it too hard because the woods makes a bad buffer zone when I'm still learning the new suspension, but it's definitely a bit faster at WOT.

Issues I'm still working out:
-Perrin still hasn't gotten me the right sized bushings for the sway bar. It's probably fine with the shims for now, but really wish I had the right parts.
-Have about 1mm toe in to dial out in the front. Rear alignment needs some minor tweaks too, but it's real close.
-Steering doesn't self center as well as it used to.
-Need to investigate a bunch of strange sounds that are probably normal but definitely new.
-Havent done any logging on the tune to make sure everything is good for now.
-I should probably get a new lower spring perch from RCE but the oversized set screw seems to be holding up for now... (This was a bitch and a half to get in but I'll do a write up for anyone as dumb as I am who wants to try)

Woot! "Final" alignment numbers. Just in time because the first autox event is tomorrow.

I bet the rear camber fixes itself if I drop that rear left another mm but I don't want to risk throwing off toe this late. Math-wise it's really closer to .15° difference but rounding makes it look worse. Might give the front left a nudge when I put on the summer tires tonight...

April fool's came late for me. Got to autox, stft and ltft were in the high teens/ low 20s. Started thinking I had some kind of exhaust leak and went searching instead of walking the track. Found nothing (considering it's a parking lot with limited time and no jack stands) and just reflashed the tune and ran with it. On the way home, fuel trims returned to normal.

Conclusion: Tune issue or sensor issue.

Other conclusion: All the suspension stuff is fantastic. Thinking back on it, I might need to up the damping a bit next time. Or just learn to drive better.

I really do love your notes & method. Bravo!

Perrin sent me new sway bar bushings last week, but forgot the lube. Got some from Amazon and finally got around to installing them. On measuring them, the hole seems to be about 0.1mm larger in diameter, though the bushings are about 1mm taller

. Definitely better than before once assembled with no shims but still a bit more resistance than I'd expect. I added a 2mm shim to the clamp on each side and called it good enough. I'll check it again after driving a bit. No pics of this one.

I do have pics of my car's new stalactite however. The sealant to plug the leak almost worked. At least I know exactly where the leak is now. On to plan B I think.

If this doesn't work, it might be off to get valve springs replaced...

Is that this?

Hmmm, is there a secret trick to not gouging out my camber plates? Asking here because the amount of people likely to tell me I'm being stupid is smaller lol.

Car is off the ground, wheels off, and I try to take pressure off the tophat when moving it.

Ultramaroon · 04-17-2023, 02:33 AM

Are there burrs on the bottom sides of those arrow washer things? Flip them over?

I think it's just a really sharp steel edge that hangs and rests on the softer plate. Probably could file it down a bit but at this point I've got the camber all set and it's already gouged.

I just read over again. The secret is to support the wheel assembly just enough to prevent it from hanging by those arrows while you scrape them across the plate. Next time, drop the car just enough for wheels to touch.

edit... wheels off... lift a little with a jack? iono but you get what I mean...

I do lift the assembly as I move it (wheels on or off), I think the little tab just hangs off the threads at a slightly downward angle. Might try a jack if I have to do it again.

I think you're right about filing. Just lift the bottoms of those arrow protrusions a smidge.
