Yes and no. The pan cars will have much cleaner air flow so will be more efficient than a lot of the other rc bodies. However the large rear wing will generate more down force than needed so will need cutting back a bit so as to not cause too much drag. A lot of the 'wings' on rc bodies are not accurate aerofoils they are just scoops so they don't create down force efficiently. I'll be using a proper low pressure undertray and diffuser to generate down force so mostly I need a clean compact body.

I think I may have to go with a 190mm width body to accommodate the full size 1:10 wheels and deal with the extra 10mm width overhang. The length isn't an issue as I may leave rear wheels enclosed..

Still struggling to find a good option. The actual pan card bodies use much smaller front wheels so I don't think they will clear. I did find an rs4 bltiz. 1:10 mini for bsr m rage. I may have to go with this and hope the large wheels fit.

What are people's thoughts on the over hang of a 190mm body on a 170mm chassis. I could get 6mm offset 36mm wide wheels which would take up most of that, but would screw up cars handling I fear..
