Roadster Shop SPEC Camaro

Very cool. I like the scanner.

Very cool that you're showing the process involved in designing the SPEC chassis. We demo'd a FARO arm with the laser scanning capability at work a couple weeks ago, but the laser is overkill for what we do. Very nice piece, though.

In for the ride.

Using the Faro Arm, followed by many hours of 3D modeling, we produced an exact 3D model of the underside of the car. Having this model we could then plug in our suspension, engine, and trans models and start designing the frame to contour around the factory floor. There was an extensive list of goals that we set out to accomplish on this chassis design. In addition to our internal suspension geometry and performance goals the big points that we aimed for were:

• An affordable price point under $10,000 for a complete chassis with suspension. (Brakes and 3rd member are additional)
• A true, simple bolt-on chassis with out any floor modifications.
• Much need strength upgrade that structurly ties the entire car together
• Low, aggressive ride height
• Keeping the frame rails tight to the body so nothing was hanging below the car.
• Ability to work with all of the different LS engine and transmission combinations
• Ample clearance for exhaust
• Accommodate a 345 rear tire (when mini-tubbed)

There are currently 9 other 1st Gen Camaros in the shop which gave us plenty of data to compare across all cars. We were able to design a complete chassis that was 100% bolt on with zero body modifications. We added additional body mounts that bolt into existing holes and/or mounting points on the stock Camaro body for added strength and support.

Here are some screen shots of the completed chassis design under the Camaro floor model.

Wow, that's amazing..!

What's the weight of the Spec Frame/Suspension compared to a stock sub, leafs and maybe subframe connectors?

Does it add much weight?

Love the concept. The 1st gen Camaro's really leave a lot to be desired in the chassis department.

they are but cant hold accuracy under .007 it seems. for cars they are overkill
