Gary adds an upgrade...the chassis we are refurbishing
 requires a lot of work. Many of the welds are cold and
 stressed. Portions of the cage were done incorrectly and
 displayed shear points where critical structure design was
 flawed or simply not considered. The supports for the main cage
 those are the "four points" that must be inserted into the frame
 rails before welded in place. These bars should never be welded
 on top of the frame rails.
 There are no books written that illustrates building a racecar
 chassis, but there are many articles on-line that explains
 basic engineering. Above the chassis, the roll cage is number
 one in importance.
 Several racecar chassis displayed on-line will show a set of
 common RH door bars. These bars were mainly a replica of the
 driver side bars, but this is not the latest design. Actually there
 is a flaw in this concept. Since the "right hand" side of most
 circle track racecars bears the weight of hitting the outside wall,
 having "too much" material hanging outside the cage renders the
 cage unsafe. The latest thought process is to keep this side of the
 car flat so the car will "pancake" the wall and not "hook", "climb" or "bounce" back into on coming racers.
 How much material you design into your upgrade depends on
 your thought process. You must remember that other cars are on
 the track with you, so prepare the cage to take a "raw strike"!!
 Please try to understand, no one here is scolding anyone.
 There is no one being singled out and criticism is not something
 I am elegible of. I have certainly learned by mistakes.
 I simply want you racers to look at one fact you seem to forget.
 Racecars are replaceable...there will always be another track
 to race, but if you do not place your safety and the safety
 of other drivers first, you have no right at all to criticize anyone else.
 Criticism is defined as judgement of person, place or thing,
 which in this case is Street Stock racecar fabrication.
 Beyond all shadow of doubt...neither Churchfield Racing nor Second
 Chance Racecars will ever jeopardize any driver, yours or mine on
 or off the racetrack (period).
