I'm still making tracks for this because I'm excited for its release. In fact, I could use the superkart vehicle to make sure it works well on the jumps, though I doubt you're willing to hand the new vehicle out - probably for the best. Alternatively, I'd like to know if the new superkart drives the same way as one of the current speedkart vehicles (suspension & steering wise) - for example, the speedkart 64 has extra bouncy suspension and is bad for certain sized ramps.
Also, idk if you're good at making bricks, but the ramps on speedkart maps would be smoother if a 1/6-1/7 ramp angle were added to the modter pack, so the superkart gamemode would have a modified Modter add-on.
