I'm not sure that's safe with the stock seat passthrough.

ah ok. Sorry to hear that...

Nice driving!

What did you think of the new configuration of the track? Does it flow better, more momentum carried?

It is really interesting! I think it's the hardest part of the track now. There's huge lateral Gs to try to get the car positioned on the right for the new left and that turn is majorly off camber. There is nice curbing space on exit which I enjoyed. I tried a few different entries - earlier and later apex, still wasn't sure which was best. More fun and challenging than the octopus which I found more of an exercise of patience. Do you drive at NJMP?

Interesting, thank you for the feedback. All the years I have gone up and down the east coast tracks, never actually drove NJMP. There were always a better track event some place, even though I am only 1:45 min. away from NJMP. Shame on me. I also missed out driving on PittRace. I certainly have regrets.

This year, again, I was determined to run at T-bolt, the same event you went to, but my wheels haven't arrived, so I canceled it along with two other events I was hoping to run at Summit and VIR. The rest of 2026 I am stuck with Summit only. Next year I am going to make it to T-bolt, one way or another, cross fingers.

when did you put the control arms on and had you maxed out OEM camber prior? How did the before and after compare and do you daily the car at all?

You get so much more contact with the road. Even with the camber gain with the stock setup it is not enough for track work.

-2.5 I’d say is min needed for track. I was looking at my tire wear on the fronts and looks like I need a bit more neg camber to get more even wear.

Back on track today with my new "upgrades". Car is fantastic on track now.
When I first took it on track last year, it was clear it was more "GT" than track focused (not a criticism, per se, just an observation). After selling my Type R, the i4 became my only track car and I decided to start modifying. My mods:
-Just changed to 18 inch wheels - Track Addict through GRP - and put Advan AO52s (had Falken 660s). The combination of the 18s with the AO52s felt great
-Upgraded rotors to Girodisc this month
-I had maxed stock camber last month (1.3 and 1.6 in front, 2.3 in rear)
-EBC blue pads
-Nitron R1 coilovers

Before these changes, I found braking to not be the best and it wasn't agile. With the changes above, braking is now excellent (I attribute a lot to the Girodisc rotors - can't believe how much better the brakes feel)

I'm so happy with these changes and it's a beast on track now. With these mods, it feels
like it's getting towards Porsche GT4 territory, hence the selection of video from today's track.

Great video footage. Thanks so much for sharing.
Yesterday (Monday 27th) was track day for here at Queensland Raceway (Aus). I had been looking forward for it, since I just installed a JB4 module.
A few of us hire the track for the day. Each hour consists of: 20 min drivers only, 20 min drivers and passengers, finally roll racing (drags from rolling start).
Performance with the JB4? Excellent describes it best. On track were Mustangs (some obviously tuned) Corvette C8, and the usual Japanese contingency. An AMG 45s drew my attention.
Nice car and driver. He was happy to go up against me to compare performance. Result:
Roll race, he took it. On track driving, the Emira was the answer for better (long term track).
