For the gt01 removing the tail lights and installing the lexan roof increases the performance alot! But that's if it's allowed at your track! A High downforce wing upgrade is also available very useful and shorter tracks.
@@jarvzRC if you run the PN center weight that goes underneath the t-plate you can run higher grip tires without rolling the car because the COG is lower. Then with the loose weights you can put some weight on the front for more grip in the front, or in the back for more grip in the back. I really recommend this over all other aluminum option parts. At my local track I run a stock 5600kv Evo with the weights and I'm getting faster lap times than even the full option PN chassis cars.
Bodies are interchangeable between different chassis but not all bodies will fit on all the different chassis... There is some info on Kyosho website support and online which may help
