Hotworks Racing mainly produces tuned diecast models especially in the D1 Grand Prix Series, mostly in 1/24 scale and 1/64 scale. More info can be found here http://www.hotworksracing.com/die-cast/
The 911 Turbo which I'm collecting is an 1/18 scale diecast. Most of the parts are 'tunable' so diecasting will never be the same again with Hotworks Racing! Some before and after photos showing a normal 911 Turbo turns into a Techart monster. Cheers!
