The R8 body was designed for parking lot racing and daily bashing purposes, so its 200mm wide body will fit both electric and nitro on-road cars. We also offer precision machined 6061 T6 wheel hubs (Item #VA107x) (http://tsais.com/products/hopups/universal.html) in different sizes/widths for you to adjust track width and the gap between tire and wheel well.
