Yesterday Helped gdcpbdcp with car to dial it in for an upcoming race. When he arrived I straighten out his car to be square and took it for a base run. Then we installed the wildthing arm and WOW! The amount that the car freed up was insane. the car came alive and was able to transition faster through a chicane and turn in faster and easier. So to sum it up If you can get your hands on them get them I know Discountrc store is out and will have more in a few weeks.
