I have a G35x (2007). I was wondering if there are any recommendations on whether i should get springs or coilovers? also, what brand and where the cheapest place to buy them.

In terms of rims? does anyone know where to get the 19's (M45 sport) rims? and what would be a reasonable prices.

thanks again, guys/gals.

PS. I live in the Northern VA/DC metro area.
