It's been said that if you spent eight seconds at every booth at the SEMA show, it would take you the event's entire four-day duration to walk the floor. Thankfully for VETTE readers, Editor Jay Heath has mastered the methods of precision stopwatch timekeeping and, like a professional reader breezing through a speed-reading course, he was able to find the latest Corvette products you should consider indispensable for 2008.

But first, some background. The Specialty Equipment Market Association (SEMA) showcelebrated its 41st birthday last fall. The event started in 1967 under the grandstand bleachers at Dodger Stadium, moved to Anaheim in 1974, and finally settled in Las Vegas-where it currently resides-in 1977. Once a year-traditionally during the first days of November-some 2,200 vendors, 2,000 show vehicles, and 130,000-plus industry professionals from over 100 countries scour the show to find the latest and greatest in aftermarket parts and accessories.

Following SEMA, in the second week of December, is the Performance Racing Industry (PRI) trade show, held in Orlando, Florida. The automotive aftermarket's second yearly get-together is a smaller and more narrowly focused event, one where hard-core performance parts take center stage. Come along with us as we take a hot-lap tour of SEMA and PRI '07. Our exclusive pass will let you in on all of the industry action.
