Owning a street legal track KE30 two door,
IMO is not the ideal platform for a drift car, I'm not saying I'm the best driver, but I have had my fair share of hairy moments in the car, and hanging it out for prolonged periods the car does not feel suited, mine is safe to do so and is quite stiff,
I beleive the car is too small and the geometry is not ideal,
not taking away anything that other people have done previously in this post,
heaps of power and stiff suspension, and a smart approach anythings possible mate
5K motor and welded diff will be a great start, and do it legally, trial and error mate
my input
