Personally i think the whole rice thing should be left to need for speed (or need for rice rather) but to answer your question yes quite a few concept by gt cars do have a wide body kit. I think the US GT5 site actually has thumbnails and pictures of all the cars in the game.
Wide body kits does not mean "rice" or "all show and no go", these kits are needed to accommodate wider tires with proper aerodynamics which relate to better performance.
Yes there are widebody kits on some of the cars, off the top of my head there's a widened Cappucino, Evo IX and Lotus Elise.Hi!
I could´nt find pics of the tuned cars in GT5P.
Especially the "Concept by Gran Turismo"-cars.
Are this special wide bodykits/spoiler on these cars?
Would love to put wide bodykits on each car in the Full GT5!!!
