This was a shakedown event at Time Trials by SpeedyGoat on August 30, 2021. The track conditions were ideal and several class records fell this day as the cool weather simply allowed more horsepower to be coaxed from the engines. The NX K24 didn’t break any records but, even at checking it out speeds, it was within two seconds of the NX GTi-R’s times. The engine and transmission were flawless all day long. Glitches did occur, but they were minor. I required a few other competitors to bump start me as the low speed idle was off and I’m still getting used to the amount of fuel that this 80mm K-Tuned throttle body can dump into the engine – so I flooded it a couple of times. The entire electrical system went dead in the paddock – turns out a connection on the kill switch which hadn’t been touched during the swap had loosened. There was a slip on the rear camber settings thus some pics absolutely make it look like I had taken the NX K24 to a stance event rather than a time attack competition. There’s a slight shudder in the axles that we are trying to decipher; it could just be the CV joint that needs to be looked at. And most concerning was that the car was incredibly twitchy everywhere – as in there were times when it would randomly pull violently towards the right. And often the right side was a solid concrete wall so this was quite concerning. When we got back to AES Auto and got the wheels up off the ground so we could look over the control arms and tie rod ends, we discovered that one of the tie rod ends had loosened off (only slightly, but that slight amount was all that it took) which allowed the passenger front wheel to behave erratically. That was an easy fix. The bottom line is that these minor items are so minor in the face of the overall size of the project that I am still grinning. Not even a spin induced by a Miata-dropping coolant all over a corner could dampen the day.

After a few changes and updates to the steering and the rock-solid NX K24 was ready to put the Feal 442’s to work again. This time at the Island Circuit. This Tilke designed track has great elevation changes and 19 corners packed into a 2.3 km/1.429 mile-long track. Plans are to eventually lengthen the course, which is obviously a small track, but the local municipality has reversed its position on the track and is now refusing to grant expansion. On this new pavement, the Feal Suspension two-way setup simply shone! It was fantastic.

Easy to tell that the aero platform will be much improved, as well, in addition to improved grip afforded by the new suspension kit. Removing the front bar [i]should[/i] lead to improved traction coming out of corners as well.
I may have missed it, but what are the specs on the new wheels? Looks like they poke a bit more, wondering if that’s leading to some scrub radius challenges, perhaps?
The Island Circuit looks spectacular, we need some onboard video Frank!
My camera game is really off right now. I have virtually no track video from the three outings that I’ve had. Yes – I was out at the track today for the final outing before the NX K24 is stored for the winter. The wheels haven’t changed – Gram Light 15×8 – but the custom LCA’s absolutely push the wheels out/forward. And I need to spend some time adjusting the rear LCA’s to pull them in better! Plus I have to adjust the rear wing. And the splitter angle is off for some reason – perhaps the antifreeze induced spin did an unknown adjustment to my splitter supports.
Billy,
Here are some of my poor video clips. Next year I’ll be better – I hope!

Cost of this setup?
Awesome to see this car still in action! A little sad to see the SR go, but there’s nothing better than having a track car that just works with no worries.
