A little bit more about the chassis process before getting back into the car build. The biggest difference in the SPEC chassis vs our previous offerings is the frame rail designs. Our Fast Track and REVO chassis both utilize a frame rail constructed from 4 sides of 10 gauge steel that is fixtured, fully welded on all 4 sides, then ground smooth. This is an incredibly labor intensive process. The SPEC chassis is designed with our RS Laser rails which crafted from various sizes of square tubing. These are painstakingly programmed, and then CNC tube laser cut to produce a high quality frame rail design that eliminates a majority of the labor. This design and manufacturing process has allowed us to lower prices with our sacrificing quality.
On this particular section, the CNC tube laser cuts a pie sections of the frame rail out.
It can then be easily bent by hand to meet the otehr side. We have added locators in every bend to easily align the pieces as they com together.
Once together, the the seam can be welded. This produces a contoured frame rail that can not be accomplished with mandrel bending. We are able to make much tighter and more intricate bends than a mandrel bender is capable of. This process also eliminates a lot of the down falls like buckled and weak areas from bending.
When completed, the seam can then be fully welded. (This is done in chassis fixtures to guarantee fitment and prevent movement while welding. The pics above were shown on a bench for demonstrations purposes.)
Our process also allows us to create compound, multi-point overlapping joints and transitions that will disperse load and add significant strength over a traditional miter cut and welded section
