The interweb is plastered with rattling shifter and it seems like it's all right at the shift box. I'm going to take it apart when I get a chance and see what's going on there. I'll look up what's required to do a shifter adjustment too.

Anyone ever see or hear of a loose shifter or shifter box? I guess it could also be something resonating through the drive train into the shifter.
My shitty Breathless Broformance shifter had a rattle. It was a loose tolerance on the bar that pressed on the lateral side springs.
But that's a harmonic vibration that happened at 2.5K. It did it in every gear. If it's doing it at just one speed and not the same RPM in each gear then that would make me eliminate the shifter itself. Or possibly something connecting the shifter to something else that's rattling or has a harmonic imbalance.

I'm going to have to mentally log every time it happens but I'm seeing it in 6th at highway speed most often. I believe that I had it happen once or twice at a different speed and rpm like 2nd at near WOT.

Did it sound like a deep shudder?

My noise? Oh hell no. It was a fucking rattle from hell.
I can tell you exactly what it was, but not sure if I can perfectly explain it.
The shifter is a "+" shape. Bottom of the shaft goes to the shifter box, top is the shift knob. The left and right of the cross press down on some vertical springs that keep the knob centered.
Image

The cut out for those side lateral bars was X wide. The bars themselves were X-.050" wide. That gap between the two just shook like a mad man at vibrations between... Let me think of this.... I think 1.6K-2.2K rpms.
So when I'd drive normal in the city, it wasn't a big deal because I'm in and out of gears and rpms. But on the highway in 6th, cruising at 70 I'd be around 1.7K and I had to keep a hand on the damn shifter to stop it.

It's starting to sound like the same thing except that mine might not be as loose. Cool brother, thanks for the feedback! :like:

Konis are in. PAINT MATCHED!

Don't have a ton of miles on them yet, but I have driven it a little. Right now they're in the middle of the firmness. Takes about 8 sweeps to go from full :flaccid: to full :dong: and I'm at 4.
Initial impressions:
Took me a while to really find the differences. Leaving my neighborhood they felt pretty stock. But as I got more into various streets and different varieties of roads in town I could see where it was different. On shifts I feel like there's less of a dive. It wasn't really that prominent before, but now it just feels like the car stays exactly the same between letting on and off of the throttle.
Side to side action is definitely firmed up. I rode around the mall, which is a loop with one really tight corner and I managed to get the back end to bark out a little. Normally I don't get this unless I'm autocrossing and have heated up the tires. So what's likely happening is the front is firmed up so the turn in is a lot better, but since the back is firmed up as well it's causing some hop which is letting it break loose. So now I see first hand what I've read about "dial in the front first and maximize your turn in, and soften the rear to match how much the front can handle".

I've still got a front sway bar coming in, so it will likely stiffen the front up even more.
I'll likely run the fronts at 4/8 stiffness and then dial the backs down to 2/8.

Also, the stock shocks, I could compress them by hand while it was in the car. These... Hell no. I had to stand on them and push down with a lot of force just to get them compressed. It was like 250-300 pounds just to get them down. It makes me think that the stock shocks were EXTREMELY soft and. Supposedly running these Konis on full soft should act like the stock setup.
I love the location of the adjustment too. I can turn my front wheels full lock left/right and reach down and adjust them without having to get the car on jack stands. So I can probably drive them to an event on full soft, and then stiffen them to a default amount, and then maybe tweak them during my runs if I'm too tight or loose.
Highway speeds on 4/8, I had some shake at 70-80mph so I might want to stay soft until I race.

I went ahead and got Strano's bar and new adjustable endlinks.
I talked to Sam for a good 20 minutes and decided to give him the extra business and go with his bar.

I could of saved nearly $300 by ordering the shocks from Amazon, but the ship date was nearly the end of Sept for the backorder of shocks. I need to run 2 events before the next 2 day club race in Oct so that I can really dial in these shocks and I didn't want to wait nearly 2 months to get them in.
:melon: and I will be racing on the same team, so hopefully we can combine our Koni Banana Koils and 4.10 Goodness into a Voltron and come up with the quickest PAX times.

Seriously. I bet he's dead. For real.

EDIT: First thing I thought. Now I revisited it and saw the half staff thing. It's likely true
I wish I could say that I felt bad, but I honestly don't. That dude instigated so many posts that I despised him.
I totally owned him and called him out on his bullshit on a Corsa thread and he didn't even own up to it even after the owner of Borla pops in and basically verifies everything I said.

EDIT: You notice how they had to lock the thread too eh?
Probably because the :caspian:s will come out of their hobbit holes and vent their relief.

Well the sway bar comes in Tuesday. So I'll likely slap it on during the week and then I can hit up the next event that weekend.
I've got 2 choices for clubs to hit up, and one just posted their layout.
Anddddddddddddddddd they lost my vote with this gem:

I did a little digging, just curious. Checked this user's post history and found this.
I'll link it and copy it in case this gets removed too. (oh yeah, the original thread is back but locked)

Which is very sad, because it wasn't that bad of a place when I had mine, and I was able to learn a lot of really good stuff there. Looking through it now though, I'm glad I don't frequent that place anymore; it makes my head hurt

I still regularly go there, but it's only to find info on certain things. And to check the C5 and Autocross classifieds. Still trying to find a pair of 18" Speedlines for next season to run a square setup.
Other than that I don't chime in a ton other than for the occasional time I've got a definitive answer to someone's question.
