I see Nitro is (perhaps unsurprisingly) the first adopter of the new OMSE/First Corner FC2, with the NEXT category switching to the FC2 for 2024:
Nitrocross - FC2 Adopted For NEXT Evo Class in 2024
Chassis, transmission and diffs from a Lite, with different bodywork and a different engine. Turbo four pot with 450 bhp, rising to 550 bhp with push to pass boost. Quite a jump in power for the support class!
I wonder how heavily reworked (if at all?) the Lite chassis is for this?
