WHEELS AND SUSPENSION??

[m3summ]

hey guys,

i have an 06 g35 coupe 6spd. im looking into doing the wheels and suspension. anyone running the h&r sport springs? and their comments? also can i run 20's on the car w/o messing anything up. i wanna go 19's in the front and 20's in the rear. any pics of cars with a list of your mods would be great. im trying to decide the perfect height with the perfect wheel and tire size. no money right now to go coil overs so looking for a nice spring and i guess ill have to bump up the shocks and struts to at least bilsteins. thanks guys
