It all depends on personal preference imo, most real race cars have a 100kg brake pedal and stock most load cell pedals come with the 100kg configuration so from a "realistic feeling" pov you will be good without the performance kit but if u want a stiffer or lighter pedal then u will need it. Trying it stock to see if you like it and then buying the kit isnt a bad idea tho
