Does anyone know the rules reagrding shoulder harness termination for DE?
We are building a 914 track car and it has a cage (CFR weld in) in it, that ties into the firewall behind the seats in three places across the firewall. Can we terminate the shoulder harnesses at the roll cage, or does it need to be terminated at the firewall and looped over (through steel keeper loops)the cage horizontal bar at the firewall? Any assistance would be helpful! Thanks |

Thanks Again,
Yes, we intend to add the steel loops to the Cage cross bar, and yes, it has been painted, but that is the easy stuff! Now, to figure out how to mount the seats to get enough flexibility in height for both drivers to fit (5" height delta). |

Now, to figure out how to mount the seats to get enough flexibility in height for both drivers to fit (5" height delta). Custom aluminum sidepanels with a row of mounting holes work OK. You'd still have to undo 4 bolts move the seat up and bolt it back on, but it'll give you 5" to work with. If one of you is over about 6'1", consider removing the cross brace on the floor and mounting the sidepanels directly to the floor. That'll give you another 2" of headroom for the larger driver.

Hey Andy, Do you have to replace the cross brace with something else? Move it forward? I have thought about this as a way to lower the seat but am concerned about changing the chassis strength. I will be putting in a Engman long kit but interested in real world results from someone who has done it or seen it done. Jim |

I will be putting in a Engman long kit but interested in real world results from someone who has done it or seen it done. I seriously doubt that cross brace adds much support. I think it was added to mount the stock seat rails. In any case, one way to do this is to remove the cross brace and weld in two square steel tubes front and rear to mount the seat rails to. That way, you don't have to rely on flimsy sheetmetal to hold your seat in place. I don't have pics here right now ... (IMG:style_emoticons/default/shades.gif) Andy |
