Word is they are 1mm shorter than kit Xray parts, When this was done by Tamiya and Yokomo their cars were immediately much more competitive, fingers crossed similar results with these guys.

I also grabbed one of their top decks, it seems quite a bit more torsionally flexy in the rear end, should be good for lower traction surfaces, and for high traction to prevent traction rolling.
