3 to 4mm (.125" - .160") thick 7075 is what you want to use. www.onlinemetals.com
is a good source for 7075 in small quantities. If you are interested in designing the part using free CAD software, and having the chassis cut out using a waterjet machine, the company I work at can help you out: www.emachineshop.com
Download the free CAD software, design your chassis and get a free instant price quote online. Design it in 2D (meaning no countersink holes, no milled pockets, etc) so it can be cut on a waterjet and the pricing will be pretty reasonable. I can help you with your design if you get stuck. You won't have to order the material if we cut it - we have access to 7075 here. Good luck! Building your own chassis is cool. My GT car is a homemade one too!
