The prices of Denny's kits are published on his website, moparsuspension.com. Spindles and brake kits are left up to the buyer.
The wheel opening of the front fender is 24.5" from the ground. This is an irrelevant point since different tire heights will change the position of the control arms.
I have welded subframe connectors in the car. Unibody twist is relevant with both CoC and torsion bars. While I have not added any additional stiffening to the front of the car, I may at some point. I have not seen any adverse affects from the HDK after 1000 street miles and nearly 50 autocross runs.
I'm sorry, but I have to disagree with you stating a welded K removes the dead spot in a steering box. My K-member was completely welded and both the steering box and idler arm mounting areas were stiffened with addition gussets. Guess what, the Borgenson box still had a dead spot in the center.
I understand you may think autocorss isn't real racing, plenty of people think the same way. I do challenge you to try it.
What I like about autocross is as follows:
I have nothing against track driving, I've done it. There's no way I'm putting this street car on a track to be competitive, that's not what it was built for. I'll do the exact same suspension comparison if you're willing to sponsor me a car and entry fees so I can be a "big dog".
- The course changes every month. I have about 30 minutes to learn the course (by walking it) and decide on the fastest route. It's not only a driver skill, there's mental skill. Anyone can pull up a youtube video of a particular road course and learn the fast line.
- Autocross doesn't beat up my street car as much as a road course would.
- For autocross, I don't have to have a full cage, containment seat, hans device, etc. in my street car.
- I don't have to worry about some other fool on the course running into my street car when I'm on the autocross.
- I pay $45 for a day of autocross. For a single open track day, it's $400+. So basically I can autocross all year for the cost of one open track day.
If you aren't familiar with the Optima series, you should look it up. There's plenty of "big dogs" out there destroying an autocross track.
