I think what femno was relaying was semi's are a thing to buy but just not the first. Improving your cars suspension while improving your driving skills and then once you have hit the limits of street tyres you will definitely be ready for semis. What's the point of putting them on to take corners at 180km/h when you can't even control the car? Much better to spin out at low speed and learn then spin out at high speed with semis and potentially damage things
but then again you vic people are odd
