For anyone that watches NASCAR, you know by now that GT5's depiction of racing at Daytona is a tad unrealistic. The NASCAR cars in GT5 are unrestricted, which makes traditional pack-racing at Daytona difficult. Ive tried messing with the gear ratios to get the speeds down to a reasonable level, but the cars hit the top speed too early. Anyone have any ideas on how to "detune" the NASCAR cars for Daytona?
