JM Auto Racing - Aftermarket car accessories, truck accessories and truck parts, and performance auto and racing parts

anybody heard of this shop? called them and they said they were very familiar with rotarys / rx8's they do tunning etc....

Their homepage lists almost every manufacturer on the market. Doesn't sound very exclusive to me. Nobody's an expert in everything. I would request a long list of referrals before having anything major done.
