my only ideia for it only a potmeter to make the car faster(like the real f1 cars not the "push to pass" button), BUT! it will able after Scawen will do the temperature meter, so you can broke the engine if you drive it too hard
only with slick tires and bigger engine? if lfstweak compatible with lx6 you can do that with it, i think. but i think the lx8 or lx gtr needs more dowforce to drive it fast so it needs wings and diffuser! like the xr class, the xrg has a small engine like the lx4, xrt has a more powerfull engine like the lx6, and the xrr is a gtr car with many settings and many downforce and much bigger engine. so in my opinion we don't need an another road legal lx car
