Streetperformance.com is the only shopping engine specifically tailored to performance automotive parts and accessories for cars and trucks. Streetperformance.com has the largest database of over 1 million parts from over 800 manufacturers. Enthusiasts find and research the parts they're looking for, compare online retailers and ultimately make a purchase. Searching for auto parts online is very difficult due to "fitment" - will the part work on my car? Currently, semantic search (i.e. Google) and shopping engines (Pricegrabber, Shopzilla) lack the data to determine which parts will fit on which cars, so auto enthusiasts have a difficult time finding information on what to buy. Further, there are thousands of merchants that sell parts online and most only carry a few brands - most of which are hard to discover. The Shopping engine is rapidly becoming the glue between enthusiasts, brands and retailers. This is even more pronounced with integration into a number of enthusiast websites including scionlife.com, mautofied.com and many more.
