The replacement for the AGX’s was a custom shortened strut housing with Koni 8610 inserts. This was a used setup that I got from a great friend and NX racer – but with the understanding that this was a cool street setup. I had just missed out on the Koni 8611 setup that had just been sold. Once again, back in the day, the shortened housing combined with a revalved Koni system was the one to beat on the track. I experimented with a wide range of spring rates – including some that were way too high for the 8610s and likely led to their demise. In fact, when I pulled the inserts out of the car there was simply no movement left. They likely died early in 2020 – which was followed by the demise of the 54C later that same year.
I was surprised when I pulled the Feal Suspension 442’s out of the box that there was a short hose between the shock and the reservoir. This can be a longer hose for remote reservoir locations, but this setup must keep the reservoir located on the shock. This was my error in assuming that the reservoir would be hard-lined to the shock. It required a bit of movement to get the reservoir to fit into the wheel well without the hose hitting anything. There was one brake line tab that was worrisome, but with a bit of adjustment, it clears just fine. I’m sure that if the unit was hard-lined, there could be issues with placement also and then you wouldn’t have the flexibility of movement.

The Feal Suspension 442 system looks incredible and performs even better! 
This unit looks incredible. While I was initially surprised that the reservoir wasn’t hard-lined to the shock, this provides flexibility to ensure a good fit. The Feal Suspension main contact, also named Mike, was superb to deal with. At the very beginning of the purchase process, he asked for details about the car. The weight of the car. About the racing done. The ride height. The tires. Mike had me measure the dimensions of the current suspension from the upper mount to the lower mount. The timeline between initiating this contact and having the 442 kit in my hands is less than two months. Mike at Feal answered every question that I had and, when it was time, provided shipping options and then the tracking number. During the installation, he happily fielded phone calls from me as I asked newbie questions about the system.

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.
