Was surfing around trying to get the best deal on titanium fasteners for the new Alutec strut bar when I decided to email Pro-Bolt to send me their 2006-2007 catalogue. Said catalogue dutifully arrived about a week later. Feast your eyes.
For a detailed rundown of the various available types of lightweight performance fasteners for automotive use pls visit The SP Files. Will be ordering some fasteners from Pro-Bolt when funds become available. This should hopefully help to reduce the Slowtra's porky weight. NO, I'm not ditching my subwoofer :P
