It will fit just fine..
You just need to make your own body pole holes to suite the Chassis, this is best done once you have trimmed the shell out BUT before You have Painted it.. (Trim it out but DO NOT pull off the Over spray film..
Then Mask up and Spray


(Yes HPI say Spray now Body hole and trim later but they are assuming your using a Sprint 2 where the Bodypole holes are pre-marked)

I have found with the last 30 Shells that magnat has done, he now Trims first, Holes Next, Mask then Sprays, removes Masks and over spray film and Decals it
His results are better then the way HPI do them as Trimming after spraying can lead to paint cracking..

As for the rims, they will look Great !
might be a bit sunken in but it should look fine..
