ive got a s4 turbo and im gonna do very basic level racing. dont need a roll cage etc. amm i was jus wondering wat settings u would recommend i set my Koni adj (yellow and jus the stiffness adjustable) shockies to. i dont care about the harshness i jus want the best handling possible. also wat tyre should i get ive got 17x8 mags but i want like a road legal semi-slick so that i get good grip without tearin up the trye to much good idea or not or should i jus get a road tyre also wat widths are best???

 

kumho victoracer v700 is great...
bfg G-force, Nitto 555 ZR, Yoko A032 all could be pretty good performing tires...
225 is probably a good size... you are limited to the front spacing. on the S4, you can't fit very big tires unless you go crazy with the wheel spacers.
