My sol was totalled and now I am looking at a GSR I was just wondering what the stock time in the 1/4 that they got and what modifications would be good to get first also about how much gas mileage do they get and so on
stock they run 15.7 but that vary depending on outside temp, timing, tires, octaine, etc.
But right around there you should be running. What is good about the older GSRs is that they are already obd1. Other than that they are literally the same except for some exterior differences in lights, taillights, etc.
