rust free you say ?  Group: Members Posts: 16,375 Joined: 7-January 05 From: richmond, Va. Member No.: 3,419 Region Association: None  |
Is it REALLY necessary ? I've done a couple of these but have yet to understand why. I have NEVER seen a trailing arm bent from anything otther than a hard collision. I see no way they could be twisting or flexing in any way in hard cornering. I'm curious if any of the hardcore racers have seen a true need for them. Anyone ever seen a ARM crack from use not rust ? Sure the consoles crack, the body cracks but the trailing arm ? Seems like unneccesary weight to me (IMG:style_emoticons/default/confused24.gif)
Talk amongst yourselves I'll check back in later (IMG:style_emoticons/default/popcorn[1].gif) |

Correct the tubes do not triangulate. What they do is keep the box from collapsing or buckling in on itself (deflection) under loading.
As far as the box reinforcement kits if you weld the outer vaneer first (laying the heat on) it will toe in. Then weld the inner vaneer it comes back... Mine did (Chris did you weld the inner first?) In the end the chassis sheetmetal is the weak link. |

Mine did (Chris did you weld the inner first?) AFAIK, the boxed kits cover 3 sides only - top, bottom, and inside face. No welding on the outer surface makes for net toe out. I'm not familiar with the outer veneer you're referring to. |
