Curious as to how to determine if the chassis is stable or fit for autocross for a car without the stiffening add ons.

To help determine this ....pictures and a description of the current chassis would be helpful.

To help determine this ....pictures and a description of the current chassis would be helpful. After everyone's comments I decided to lift the car and take a look. From the bottom, I found holes at both hell holes about 3 inches diameter. Im assuming this is where the drain holes used to be. Difficult to tell how bad the rust since its all completely covered in undercoating underneath (Ziebart?). Also a slit hole 3 inches long where the battery tray rests on the inner fender. Next I will take off the rockers to see if there's any rust there. Jack points and jack holes look ok. I'll take pics when I get a chance. These areas will need to be repaired at some point but are these areas critical to chassis integrity? |

This is not going to be fun to hear - you won't have a functional race car unless that is fixed - and its probably worse then it looks right now. You are going to need to get in there with a wire wheel on an angle grinder and take it back to bare metal and see how far the rust goes. The longs are the backbone of your car, and if the rust gets bad there your car can literally fold up - especially with the added strain of racing. Fix it now while its small. Zach |
