Can't wait for some new spur gears. I checked last week and Tresrey was out. I just built the car and will run for the first time this Friday. I'm not sure why they put an 87 spur in 2wd buggy kit; the biggest pinion I can squeeze in is a 25 maybe a 26. Luckily I'm running an 8.5t so hopefully it isn't an issue.
