    I just bought two clk430 convertIbles hoping to make one of them
    into clk gtr- the roof is already off when using a convertible so the structure is strong

    have you sourced a body ?

    I've been re-working the chassis design, in particular the front suspension cross member. The new version flows better with the hood line and isn't as boxy as the first version. It also gave more room in the foot well. Here the 3rd Gen Mazda RX7 Windshield is included, along with a slice of the CLK GTR Body over the driver. That's me in there at actual size, I think I stole that one from Joel. I left my glasses on to see better. The drawing helps work out things like ground clearance, roof height, leg room, cabin width and steering wheel placement.

    The front end uses Corvette C4 components, rotor to rotor including the rack & pinion. I was considering taking out the anti-dive in the upper control arm but left it in for now. Making tubular A-Arms with heim joints was also in the plans but I decided to keep plowing ahead with the stock Corvette parts.

    .
    As with the rear suspension cross member , the front one is made from 1.5" x 1.5" 16ga square tubing along with 1" x 1" reinforcement braces added.

    I source these chassis tabs thru AA Manufacturing in Michigan, USA. They have an extensive catalog of common and uncommom brackets and tabs for suspension, steering and brake parts for race cars, dirt track, sprint and kit cars.

    Looking good! You're smart to design the chassis and bodywork around a "off the shelf" windshield from a factory made car. I didn't do that for my GTO and am really regretting it now.

    Thanks Chip, still learning new things in SketchUp and watching a lot of tutorials helps.

    Joel, its true how critical the windshield choice is and can be the difference between a good car and a great car. I was going with a Solstice glass then spotted a RX7 at a car meet, it looked like a better option.

    Here's the jig I made to locate the Corvette C4 steering rack correctly in the tube chassis. I used the original suspension cross member to locate the 2 'dummy' lower control arm bushings. One side was made removable to assist it taking it off the corvette cradle.

    The stock Corvette C4 gave up its center section for the cause. I considered selling off this part but I chose to sacrifice it to save time fabricating the mounts from scratch. And I got to use my plasma cutter.
