Posted September 24, 2007 Below is a kevlar / carbon fibre tub chassis for the S4 which Mat Dodd is testing, the chassis has a outer layer of kevlar and the normal inner layers of carbon fibre, the kevlar should help reduce any wear to a minimum on the chassis, and also doubles up as a small bullet proof vest in emergences lol. The only draw back is with kevlar is that when you do wear down to the kevlar it can get hairy. http://www.oople.com/forums/showthread.php?p=61287#post61287 Share this post Link to post Share on other sites
