Hello to everyone here. I'm laying out my chassis for my scratch build Mercedes CLK-GTR Tribute street car and need advice on tube sizes as I want it to be strong but not too over built. I plan on using round tube for what will make up the 2 main roll bar hoops at the windshield A-pillar and B-pillars and their overhead connectors. Note: the doors will hinge forward off the A-pillars. I am considering 1.5'' or 2'' round tube in 11 or 13 gage. The remainder of the chassis will consist of square tubing 1.5'' x .060 (40x40x1.5mm) with secondary supports from 1''x1'' x .060 (16ga) 26x26x1.5mm.
The cars specs:
Audi 2.7ltr V6 bi-turbo 240HP
Boxster 012 5 speed
Corvette c5 susp & brakes all around
100'' / 2.55m wheelbase
Target weight 2300lb/1043kg
.
Any advise on choice of tubing is greatly appreciated, If I may have left out something critical needed just ask. I look forward hearing back from fellow members and starting to build this dream car of mine. All the best, Vinny
Below are a drawing and photo of the actual race car. I'm not building a monocouque as the original, instead I will clad the lower half of the tube framed cabin with aluminum skin.
