I bought my 95 vert with stock 15 inch wheels and stock 205/55/15 tires on it. Using my GPS, I noticed that at 55-65 mph, the speedo was reading 4-5 mph faster than the GPS reading. I upgraded the wheels to 16 inch Gen7 and put 215/50/16 tires (I understand that this was the stock wheel size/tire combo on the gt4). This made the overall diameter of the tires/wheels about 1/2 inch larger. My speedo now is right on.
