I am about to purchase wheels and tires for the Z and have found these forged wheels they are Nurburgring Wheels by TSW so I want to know if anyone has any experience with these or if someone can tell me what offset to order. I am looking at these because they are light weight and look pretty cool. Tire sizes for the front and rear would be great also, i think i am partial to the 18X10.5 rears This is the rim: [ http://www.tsw.com/alloy_wheels_Nurburgring.php ]
