ok some of you sound experienced in autoX.....and this is my first time heading out.......so i got some questions.....

Are there any clothing restrictions.....my friend got the boot at the drag strip for shorts one night??

My car......has a custom dual exhaust incorporating the stock muffler and all stock parts, short throw shifter, 205/55R15 instead of stock 195/55R15, i got some holes punched in my airbox, K&N filter, strut tower bars, stillen lower g-load bar.....any idea what class id be in......or do they tell me??

Any idea what time it starts at Maple Grove on August 4th??

Thanks for the help!!!!
