How to beat b spec 'like the Wind' gt5?

I completely tuned up the Mazda furai and the pagani zonda but my best driver (lv 22) won't get a gold! The best he's done so far is a bronze. Help me!!!! BTW I can't do a spec well :(|||hello, i had this problem for ages, the best thing to do is try and get as far as you can in a spec and spend as little money as possible, then you need to buy (or win) a good level 22-23 car from either the used dealership or the online dealership, tune it up fully and then your sorted no problem. try and do as best as you can in a spec because you will effectively double your money and the cars to choose from :) hope i helped :)|||use a formula gran turismo car or the red bull x2010 and you will easily win it
