Rebuilding my race car, multi link rear suspension, fg gt flairs Options

[slugmika]

I had to make it public. That's the only way i'am going to get anything done.
So, i had to convert my rear suspension to multi link, raise the front suspension, built a new pedalbox, rebuilt the engine and tranny, make attachemets for new fg flared rear and front fenders, make a new carbon top, glue the new heated windshield, paint the car and lots of other stuff.

I will post pictures when ever i have any progress.

Here is the starting point

First let me say you know a lot more than I do. I have only read books. This stuff fascinates me.

When I meant toe, I meant toe when your car is in a turn and hit a bump. What does the
rear tires do then? Do the tires toe in. toe out. by how much. Is there any toe dialed in
for acceleration or braking? It hurts my head to think about it:)

I am sure what ever you are making has to be better than the stock 914 suspension rear
geometry. Flame suite on.

I am not 100% sure about this but some cars like the old 240z the rear suspension seemed liked the toe
does not change on it through out its travel. While the 914 stock suspension does. That long semi-trailing arm creates toe & camber changes as it goes through its travel. It seems like the tire would have a lot of leverage againts the rear suspension of a 914. I think it would be very difficult for the rear suspension to make the tire go where it suspose to go.


When you design the rear suspension did you have to take into a account how the front suspension works (camber changes, roll centers, etc..). Did you have to take into account the wheel base? Or can you just design the rear suspension independent of the front?

As an example I wonder what would happen if took the rear suspension off the 1992-1995 rx7. car
with double wishbone front rear weight 50/50 and put it on a 1987 mustang. different wheel base.
the front suspension is strut. I am guessing the wheel bases must be different and the mustang
is more like 65/45. I would think this car would do wierd things in a turn hitting a bump.

I can not wait to see the finish product and the test results.
