Yeah I spent the money on this one already, so I'm going to stick with it. Clearly it can be made to perform. Going wide open throttle on a track is all I wanna do with it.

I sent Stielow a PM, hopefully he can help me out. I would love to see what I have work.

I have fixed a few in the past. Can you post a picture?

You either had to raise the rack or modify the steering arm to get the bump steer readings better.

this was a shot of the mule. I believe it has been changed since then too. Not sure.

We moved the rack down and move the lower control arm brackets down and made steering arms and use bump steer correcters also. Motor was still high though. And bump steer is still in it.

Looks like Mark made diffferent steering arms also.

I agree with having to raise the rack. I put a Longacre bumpsteer gauge on my old WD subframe and it wasn't good (don't remember the range at +2, -2), but the only way to reduce it was to use the Baer Tracker spacers and move the steering arm pivot point lower. But... because the Baer Trackers are so crazy huge in diameter, I couldn't got as low as needed because they would hit the LCA at full lock. The right fix would be to raise the rack. The other issue I had was ackerman. It was basically nuetral at lock, but the only time I noticed it was when I was backing out of a parking spot - low speed, full lock, in reverse. It felt like it wanted to drag the inside tire a little.

My solution was to switch to a DSE subframe.

Not sure on what kind of angles will help the best but here are a few pics.

Nothing is bolted in real tight, it's all just mocked up right now. I have to find the directions again but I think all the fabrication to make everything work has been done already.
If more fab is needed that will be to address the bump steer issues. Name: 100_1446.jpg

I have a C4 WD as well. Mine looks similar, but yours appears to be newer. I dont have the extra bracing from the motor mount perches up to the suspension mount. Your control arms look different as well. Have you thought about subframe connectors? I was going to use the hotchkis ones, but they wont work without modifying them. The boxed end frame rails really limit what you can use since most of them insert into the end of the frame rail. I'm just going to run the DSE solid mounts for now until the car is done. Mine is mainly a street car , the only track time it will see is at the drag strip a few times a year. What motor you running?

I want mine to be mainly a track car, that I can terrorize my community with from time to time haha.

I'm planning on building a 434 small block. I bought some GMPP 18 degree heads a few years back with a ton of quality parts for my top end. So now I've just got to get to a point where I can afford to buy the short block.

As for subframe connectors... Haven't put much thought into them yet. I have to replace so much sheetmetal. One rear frame rails is bent from an accident before I bought the car, so I have to figure out what I'll do about that.

I feel lost in my build sometimes. like I might be doing some stuff backwards haha
