It really all depends on what you are doing. Are you going to do the Beg, Am, or Pro race? If you do any but Beg, they wear out so it does get costly. But if you go with MEDs they work great. On my Carola I had the Med. They work fine. if your competition is hard you should drive better than usual, but if not, dont worry. I did it my carola aginst some monster cars and it took me a while of 3rd and 4th

to get $$$ for softies. THEN I kicked ass
