I have 3 favorite combos I like.
Pink Rear, Purple Front (RC4Less)
Yellow Rear, Med Gold Star Front (Corrally - Could use Jaco Pinkx2 for fronts)
White Rear, Pink Fronts (RC4Less)
All of the above combo's are balanced for my setup so I can switch between the different combinations without making any chassis adjustments, and the car will still handle very neutral. I highly recommend RC4Less, the rims are super strong, and they dont come un-glued ever. They also seem more resistant to chunking then some other brands.
