If you do the TPMS learn with the tires at cold starting pressure it doesn't care and will use that as your "ok" pressure. I do agree that it's an extra step, but I like having the temp sensor info it provides since it gives a good indication of when things are getting too hot. I've found on...

Nice! The RZ has been a game changer for me this year. Way less of a knife edge than the RS, and much more info given than the Yok so you can make real line decisions. I bet with a well sized RZ there's some significant time there. One note on the sizing, I ran a 275/40/18 Yok up front for a...

I had a C8Z at the time which rewarded staying on throttle slightly for stability since GM thinks it's a good idea to unlock the diff when you lift throttle in a mid-rear car. To be fair I only got that high on one of the laps. Most of the time I was 95-105 until I worked up the courage. I'd...

During One Lap in '25 the FD track was initially slated to be used, but it was changed after the prior weekend wrote off a few cars due to the close walls. I liked the standard layout well enough, and to your point it flowed well. I think the FD track would reward some of the lighter lower hp...

For small parts like tie rods or o-rings you should work with a local toyota dealership (or one of the major online dealers that sell parts) since they're going to be the cheapest. For larger parts, find someone (or several someone's) who run businesses parting out cars. Airbags and large...

I thought it was fun when I went there. I don't think we ran the FD setup (that's the tight one, right?), and it was fast/flowing with enough limitation in the banking that you had to think about things before committing to throttle for the front straight. Turn 1 is similar to Nashville Super...

It wasn't great when I was there during One Lap in 2025, but that was my first time there so no prior reference. Still, bumpy, not a ton of grip, etc, but at least it had rained the night before and gotten some crap off the surface.

Yes, stock dp, Borla exhaust.

I've posted multiple videos of my car with the Borla exhaust on track. Sound is via a Garmin so not the greatest, but it'll give a good idea. For example:

Lowering the car will get more, as will moving the camber plate until just before rubbing. I have -3.5 up front on H&R springs and camber plates. That said, there will be much more adjustability using front arms with camber plates, and keeping the ride height higher keeps the car off the bump...

Not really disturbing, but if the exhaust is pointed at a wall and it's within 50 feet it would be noticeable inside the building. The Borla is more or less a straight pipe when the valve is open. The stock programming of having the valve closed during cold start helps keep it quiet, but if...

It's loud enough that you can actually hear the car on track, which was my goal. Cold start (with the valve open) is much louder, but not unbearably so. I fired the car up when it was an open down pipe and the Borla is actually about the same with the valve open since it's a straight...

I have the borla valved exhaust on mine. More or less stock noise levels with the valve closed, and a solid exhaust note with it open. The only thing I have to complain about is the valve will rattle on cold start. I've tried bending the spring for more tension and it helps, but doesn't...

I did it myself and it was pretty simple. You can do it without removing the front shocks (and they're likely quoting you R&R on the shocks). Get the spring compressors (or rent them) and make sure to do things slowly. There are several write ups on line so I'm not going to write it all here...

Yeah, I've worked with similar bolts before. In this case I spun them around 360 degrees several times while also pushing/pulling on stuff to make sure the adjustment was doing what it should be. Camber would go over -3, then back down to -2.6. Between the start of this thread and now I spent...

No, I've had events or day job work that's gotten in the way since starting this thread. I hope to dig in more over the winter, but I've got 2 other cars I need to work on first. The first step is going to be getting it on another rack and measuring a bunch of stuff to see if something is...

The BS facebook group will likely have more answers. That said, the few BS car's I've looked at all seem to stuff 295 square on the car. If you're not chasing the top of the class then staggered 275/295 on oem wheels is also good. Regarding Tire Rack, if you call them they can help more in...

I don't think you'll get many good answers since most are using an external GPS puck suctioned to the windshield, or something similar that has a more direct line of sight to satellites. You would probably be better served by asking GoPro themselves to see if the antenna inside has had any...

I realize I never responded to this after reading from the thread bump, but evidently it does. I had one other person PM me saying they had the same issue and wanted some details on wiring. After the first ever track day at CMS where it had the issue I have tracked the car in even hotter temps...

Brian, the HKS kit isn’t legal in S2. I asked Because I was going to do the same. The happy limit remains 275 on something narrower than an 11 up front. If it were legal I’d be running it and using much wider wheels.
