Re: Callaway Supernatural 475
the brakes and the coilovers were addon options to the 475 snat pkg .Callaway to me was a very pricy place to take ones car to mod. their porting was minimal at best at least from what i have seen . inj housings look like they just had the casting flashes taken off. i have seen cars that have just inj housing and plenum, port work done make 15-20 hp more than the callaway. but thats just my opinion, that and 10 cents gets ya a cup of coffee
