Usually is, especially if you want it done by Feb. I had mine shipped when my local supply company restocked so I paid no extra shipping. His are VERY GOOD QUALITY. You'll be very impressed with his stuff. You can use them with the nose you have. But, I very highly doubt the front tire covers will work with your nose, so you either have to make them or not run them.
I plan to make a race in March at Dumplin since the series will be on Maxxis tires. Can't wait, really hoping some opens show up for that race. If not I'll just run stock classes.
