No,the lug spacing is different. I called up the Cadillac service department to confirm.
Yes they will run a 245/30/22 or max 255/30/22
No the cts- v has a six lug rim.
will a 5x144.3 fit a 04 cts
Yes, the grille from the 04-07 cts-v WILL fit on a 03-07 cts.
Not completely Stock... With slight modifications to the front plastic portion of the wheel well. A 22 inch rim with 255/30/22 tires can fit. HOWEVER! With stiffer springs there will be ALOT less Rubbing... See what they look Like --> http://i40.tinypic.com/2nb7k1j.jpg
No only 22" inch rims will go that's the minimum FOR A 2003 CADILLAC CTS.
