while forgestars are light they are far from weak. flow formed is one of the strongest ways to build a 1 piece wheel. if you think those replica wheels (cast) are stronger you are sadly mistaken.
remove the duo valve, coolant tank and egr setup. might get you 8 to 10 lbs off the engine bay.
btw there was a member on here racing his xfire in full race form when the car was nearly new. in fact he dropped a manual trans in his srt to reduce weight even more. you sir arent reinventing the wheel merely following in the footsteps of those before you. we joke we jest and we poke fun at those who ask questions they should already know the answers to. we also help broke down cars give away needed parts to those that cant afford new and dispense knowledge and info freely. from rudy and his v8 engine swaps, to rob to maxichon, cjw,woody, grip so many others.
have fun with your car and remember you came to us we didnt ask you.
