I have had many TZs over the past few years; but after comparing them with my Novarossi SCT, I never looked back. I know, im comparing a Toyota with a Lamborgini in terms of prices, but just sharing my experience. In short tracks, the TZs hold up on their own and for the price, you cant complain... I'd suggest if you need to stay on that price budget of the TZ, next time get a JLR Red Dot... Those engines are crazy fast out of the box. But for starters, stick to the TZ until you see it die... Have fun...
