If I were you guys I would save my money and spend it elsewhere rather than on expensive semi slick tyres hoping that will make you a better driver, fix all your problems and get you faster times.
Semis = faster corner speeds which means lesser margins for error and also = much harder hits when you collide with something.
Most (not all) of the time cheap semis that have gone through a few hard heat cycles, stick worse than street rubber.
Get decent sized street tyres that will last substantially longer than semis, and save on regular fitting and balances, and spend money on the basics; good pads, good fluid, coilovers and or swaybars, and suspension links that will give you better turn in and decent camber (castor/tension and camber rods). Those get you faster times and arent consumables like tyres.
But hey, if you wanna run semi slicks and be cool, then thats ok too, just my 3c.
