SGP Racing in Deer Park isn't one of those places you drop off your car for a quickie oil change or brake check. It's the place where serious speed and performance enthusiasts might leave their cars for weeks for engine overhauls, ridiculous amounts of horsepower (600, anyone?) and new computerization systems. Their motto, "Performance, not promises," is apparently true, judging from the abundance of shiny Supras, 300ZXs and Hondas holding court in the SGP parking area any given day. SGP is as much a place to upgrade your ride as to talk noise with fellow adrenaline junkies about adventures behind the wheel. Step inside, and it's like walking into a dream world for modifying your ride-shiny rims, tight front ends and accessories galore. And if owners Mark Gust and Kyle Puckett don't have in stock what you desire, they'll order it for you. Or you can just flip through the catalogs and dream.
