I have my third Mustang. A 2005 Mustang GT. I wanted to know if running the purple 2w/20 oil makes a difference. Andi I have stock 17" machined bright aluminum wheels and would like to upgrade. Any suggestions. My car is Yellow with black racing stripes nad I was thinking of 18x9.5 in the front and 18x10 inthe back in black deep dish billet. Any thoughts or suggestions?

 

go 20's on an 05. they look like the 18's on earlier mustangs.

 

Id go with 19"+ on an 05 mustang. They have a lot of wheel well and it sure looks good with big rims.

 

I agree,and lower it and they look damn good.
