*UPDATE* Redcat Caldera XB 10E
 

I have searched the web to find out what wheels will work on this vehicle due to the odd offset. Well, as luck would have it, they were having a RC buggy race at my local hobby shop and I have found the answer... Losi XXX SCT rear wheels. They are 12 mm hex and have the perfect offset. They will work with the 2.2/3.0 M3 style tires, so you will be able to find these in abundance.
If you have questions or comments, let the discussions begin.:cool:

Thanks for the heads up.
