I might unlock and have the ECU tuned after my warranty expires. Not willing to give up the warranty this early on in the cars life.

Level #1 on the JB4 does nothing, you are running stock. Level #2 requires 91 octane Level #3 requires 93 octane Level #4 requires E85, or 93 octane or better. If you add the airbox lid with larger MAF tubes you'll get a Level #5 custom tune to adjust things for that extra airflow. Order a 54...

I'd like to put together a "group buy" to negotiate a better price on Forgeline wheels. Anybody else interested in them? They are what John Heinricy is using on his CT4 BW. Here's a link to the 2023 runoffs. Other than wheels, tires, brake pads and sway bars, that's a stock car.

Just as the JB4 fools the computer into making more power, the larger MAF tubes do as well. If you have both the JB4 and the airbox lid with larger MAF tubes you'll get a custom tune for the JB4 going one step farther than what it comes programed for.

Well, I didn't do it to it yet, but I've done it for it. Just ordered the Refined Performance sway bars and Swift Spec-R springs. That should increase the speed everywhere on the track and take a few seconds off lap times.

It would be nice if Cadillac came out with a Precision Package for the CT4 BW as well. Since they haven't, I'll assemble my own. I just ordered the sway bars and Swift Spec-R springs from Refined Performance. The Refined Performance springs are 30% stiffer than OEM, while the Precision...

Mount one of your 275/35's on a front wheel and test fit it. If it works then 275/35-18 can be your square setup. If they are too tall, I know 275/30-18's will fit mounted on 18x10 wheels, so that could be your square. You could also go 285/30-18 square or even 295/30-18 square on 10" wheels...

I'm hoping someone would be willing to nearly donate a damaged splitter to a racing cause. I'd like to play with it and modify it for more downforce for my track day adventures.

Resale value - correct, some buyers wouldn't care, but some buyers wouldn't buy a car without it. IMHO

Reporting on the topic of track day tires and the Michelin Porsche Cup N2 slicks I tried. This stuff is all new to me and I'm learning as I go. The shop that mounted the tires probably inflated them to a standard 35psi. I put them on the car and out I went. Fortunately I was sensible enough...

In order to do this analysis you need to have clean laps. I'm dealing with so much traffic I rarely get a clean lap. I think it may be time to try driving with the "C" group. But I also need to start working on late passing and entering turns from an inside line, so there's still a lot to...

First and foremost was manual shift. I would not have bought the car except for that. I ended up with a dealer's Watkin's Glen car with the PDR. I had no interest in the PDR at the time. Now I would say, don't order a car without it! I had never been on a track before, now tracking it is my...

I watched this again and damn you are really pushing it. 1.6g in turn 3 - wow!

Wow, I think I might feel lost with all that space everywhere. Here's July 4th at Watkins Glen. Look how tight things look compared to Sonoma. I'm running Porterfield brakes, which have really increased the stopping power and pushed back braking points. 2.7 front and 1.7 camber. I'm...

Summarizing it briefly: I had posted an ad of bronze wheels wanted for a CT4 BW. Some time later I received a message from Trojan2029 saying he had a buddy here on the site that had a set he'd be willing to sell. He said the person was xxxxxxxx on the site and that his email was xxxxxxx...
