Hi there,
So over the years I have seen all sorts of ideas, lots of products etc.. Seems like we are chasing our tails. Here is my dilema, and I would like to get some input. Take a 34 year old chassis, fix the rust. Add super stiff suspension. Bearings, bars etc. add really sticky rubber. Now, what gives in the chassis...where is the weak spot. Say I seam weld the suspension console. What next...something needs to flex, or it seems to me that something will break instead. I ahve seen pics from McMark of a cracked long inside, and in the miidle of the span..not a rust issue per se, but a fatigue issue. So, where can I engineer in flex, so the chassis wont crack, or break a weld. No Cage allowed. Just the chassis. Currently there is not inner long kit, or outer...just good repair work on the rust to date... Nothing is cracked yet...but something will have to give.. I just put in roller bearings....now its really smooth, but now more of the forces are put directly into the chassis... Rich |

Weld the dorrs shut to add some more strength?
You are trying to use a 4"x6" sheetmetal tube to keep the while car straight. It just cant keep up w/ modern tires w/o some help. BJH |
