I just took the calipers and went to the garage and see if they fit and guess what they do fit.. except I need a bigger disk diamiter. What is the biggest diamiter I can get for a 4 Lug.. Thanks.

Here is a pic of my car when I was at the track..Yes I know the color is not everybody cup of tea but it was a right at the moment.. The car is being rebuild again and repainted with a different shade of blue/silver.




Picture below is when I first got the car..
