[QUOTE="Speedboosted, post: 15204025, member: 156558"] At the time, both Weir Racing cars ran 2.73 gears. Jordan set the record at that event. For a mile, 2.73 gears make the most sense because you cross in 4th, where a shift to 5th at those speeds is a killer for mph. As for tires, the stock Goodyear tires would be okay, but the R888 like you mentioned would be tremendous. The Hoosier R7 is most definitely a dual purpose track tire, but way overkill and if you had to ask about an R7 for road course use, you aren't ready for them. I would try to grab the R888 if you can. Those gloves Norton linked aren't bad, but I prefer 3.3/5 spec gloves for the extra fire protection. The G Force helmet is very good, especially for the money. You should try them on first if at all possible. I don't know if I missed it or not, but how much power does the car have? That will play a role into gearing as well. I would try to gear the car so it crosses the mile at the end of 4th, so you'll need to look into 3.08, 2.73, gears like that, again depending on power level. Cooling is another big factor. Hopefully the car has at least 1 7/8 headers, an ice tank in the trunk, and the tune is spot on. Try to datalog the first couple passes if they'll let you. I was able to log during Shift Sector with a laptop in the passenger seat, but I doubt the US mile will allow that. If you have an NGauge, logging will be easy to do. [/QUOTE]
