I think this car has some suspension mods, but not sure what. Wheels are wider than stock and wearing Hoosiers.
Video is from the SCCA Pro Solo at Z-Max Dragway outside Charlotte, NC last weekend. Pro Solo is autocross, but differs from the regular autocross format by normally being two (as close to) mirrored courses (as the site layout/conditions allow) and featuring a dragrace style start, complete with a Christmas tree light start lights. Where a normal autocross course will often see run times around 60 seconds, Pro Solo courses normally see run times in the 30 second range.
