Ultimate Street suspension guide

So I want it level with me in the car, up to the body seam, which I'm assuming could mean the bottom of the door, what height is your car set at to the bottom of the door.

Brian, what rate are those?

175 in the front, 120s in the rear

Like Mike said. Brian, you'll want to have a friend help you get the car to sit level with you in the car. Use a tape measure with the car on flat, level ground. Measure from the ground up to the body seam on all 4 corners.

Put it on the car as is. Let the suspension free hang. The spring needs to be under tension even if the tires leave the ground. Once all under tension you can adjust even more to get more preload and a bit more ride height. But that's about it for my abilty. I put me so I had tension. All around. Then adjusted them both the same amount up just to make sure all was the same.

im confused by this picture!

How do I know where to put my spring nut for install. Not Pedro ride height, not off road either

Where do I set my spring nut height to install

is there any factory or race suspension design that automatically toes one side out and the other side in depending on which direction the car is being turned? would this give more ultimate control than both sides toed in?

The festiva does this without complicated contol systems. Think about what happens to a trailing beam during articulation. The outside toes in and the inside toes out. The more negative camber you have, the more this happens. Do you think it's a fluke that these things out handle supercars with ease? Our little cars are amazingly well designed, but they detuned them. The trailing beam is the best design I've ever worked with.
With my 5 degree spacers the toe change is almost 1:1. So basically 1 inch of suspension articulation causes 1" of toe variation between sides. I'm excited to dial this in and see what it does on the track. There is a good reason why I've spent so much time with this chassis when I have a garage full of supercars to play with whenever I want. The Festiva chassis is no joke.

The festiva already has this in the front! It's called a steering rack... :grin: ... sorry, couldn't resist.

Other cars have 4 wheel steering, quite a list of them actually. Some RX7s are a common one. Here's a list: https://en.wikipedia.org/wiki/Catego...wheel_steering

Now, wether it's really beneficial or not is another issue.

Not for the festiva! and i think the 3000gt cars had something like that. I think they called it 4 wheel steer. But they canceled it!

Yea, I'm working on it. Right now my 4 axis machine is setup for making titanium pieces for superconducting cyclotron coils... I thought I would have been able to make a few sets by now (I need 2-3 sets immediately myself!) but I've just been too swamped.

Plan is to make them for ~ -3° for now. I know I won't make much money on them, but since I need some I figure I'll make a fixture and supply a few sets to others (through the festiva store).

you could send me a sent!

Thats just cool!
