Thanks champ, I'm really happy with how it looks but there is just a little suspension issue which I have to clear up at the front, and mounting issues at the back.
As stated before they are Genuine HSV VE R8 19's. They are 19x8 at the front and 19x9.5 at the rear. Tyres are 235/35's at the front and 275/30's at the rear. They cost me $2100 for the set of 4 rims and then they needed to be machined to fit the a VT, and then I spent $980 on tyres... and yes, they are real!
I've got a picture of the new rims on the front with the old rim on the back and it really stands out and makes the old rims look tonky. I'll upload it tomorrow.
