So I bought the 10 piece chassis kit and the trailing arm box kit and the car is prepped for install. My car has never had any rust issues and looking at the bare metal everything looks great. I can't find any cracks or any other irregularities. The car is autocrossed at least monthly and I am attempting to stiffen it up. I will fab up a inner ear brace as well and rollbar is in the works too. Well I started browsing and I guess some of you guys don't like the 10 piece kit. Should I just leave it off and stitch weld all the body seams instead? What about the trailing arm box kit? Am I going to be adding weight that isn't going to benefit anything?

Thanks J P, I wasn't accounting for adding stress risers. How did you tie the cage into the rear struts? Do you have a back window? I still drive mine on the street from time to time.

You can go lower than the window, through the firewall (or even sandwich at the firewall). Not the ideal angle, but it will work. (IMG:style_emoticons/default/smash.gif) |

(IMG:style_emoticons/default/smash.gif) I did mine like this: (IMG:http://i31.photobucket.com/albums/c395/odg743g/IMAGE_028.jpg) (IMG:http://i31.photobucket.com/albums/c395/odg743g/IMAGE_027.jpg) (IMG:http://i31.photobucket.com/albums/c395/odg743g/IMAGE_026.jpg) cut a new perpex/lexan back window.... job done. First thing I would recommend is a decent cage like mine that attaches to the body in at least 6 places (mine attaches in 10 places). I also went for inner long strengthening as there was already cracks forming by the handbrake before I fitted the cage so as I was rallying the car I didnt want to take any chances so I went for belt and braces with a cage and inner long strengthing. (IMG:http://i31.photobucket.com/albums/c395/odg743g/IMAGE_032.jpg) (IMG:http://i31.photobucket.com/albums/c395/odg743g/IMAGE_038.jpg) I also bought a rear pickup point strengthening kit from CFR, including inner ear strengthening as I was conscious this was a weak point in our cars and I was going to be stressing it out more than most (IMG:style_emoticons/default/happy11.gif) (IMG:http://i31.photobucket.com/albums/c395/odg743g/IMAGE_034.jpg) (IMG:http://i31.photobucket.com/albums/c395/odg743g/IMAGE_043.jpg) (IMG:http://i31.photobucket.com/albums/c395/odg743g/IMAGE_044.jpg) (IMG:http://i31.photobucket.com/albums/c395/odg743g/IMAGE_039.jpg) (IMG:http://i31.photobucket.com/albums/c395/odg743g/IMAGE_040.jpg) (IMG:http://i31.photobucket.com/albums/c395/odg743g/IMAGE_041.jpg) on the rear arms I can only talk about my own direct experience (I have NOT AX'd with this car) I only rally it (IMG:style_emoticons/default/driving.gif) on tarmac and gravel. I have bent 1 arm, twisted another and completely folded in another (hit a rock on a side slide at about 50mph - the rock won (IMG:style_emoticons/default/blink.gif) ) Since I've fitted some of the arms with the tubes welded through from PMB Performance - Eric Shea if I remember rightly (someone correct me please if I've got myself mixed up and it's someone else that makes these.... it was some time ago I bought them and fitted them) But the main point I'm trying to make is.... since I fitted them a few years ago I have not had them bend or fail on me in ANY way. They are ROCK solid and believe me... I've been trying my hardest to bend them (IMG:style_emoticons/default/biggrin.gif) Hope this helps (IMG:style_emoticons/default/beerchug.gif) |
