Hi everyone!

I am designing my own trackday car from scratch. I am now designing the suspension geometry.

I have read several books about this topic, and I know more or lees how it works everything. But I am still lost when it goes from pure theory to reality and real numbers. I have no idea if this numbers are good or bad. And I ask you for some help.

I want to design something similar to a Radical PR6, and it will be just for tracks, no street.


So, here I show you a few pics and data so you can guide me.


This is the front view of the suspension (I am still calculating the side view and the "anti" features):






These are the main properties of the front view:


Camber Angle (deg): -2.50
Kingpin Angle (deg): 6.20
Kingpin Offset/Scrub Radius (mm): 34.00
ROLL CENTRE HEIGHT (mm): 20.14

GENERAL TIRE DATA
TYRE ROLLING RADIUS (mm): 292.10
WHEELBASE (mm): 1600.00

RUN DETAILS
BUMP TRAVEL (mm): 30.00
REBOUND TRAVEL (mm): 30.00
ROLL ANGLE (deg): 2.00



This is the roll center height due to suspension travel (positive x values mean bump, and negative mean drop):







This is the camber due to suspension travel (again positive x mean bump):






And this is the camber due to roll (now there is one graph for each wheel, but one is exactly the opposite of the other)








I can plot a graph for almost any measure you can imagine, so just tell me if you need anything more.


P.S: English is not my native language, sorry for the mistakes and please ask me for anything you don't understand!



Thank you in advice.

Provided your Hub is already selected and you have to use them, the following points will be addressed if it were mine:
- Raise Inner Pivots for Lower Arm so Lower Arm is Level @ Ride Height.
- Put Swing Arm Pivots in Chassis in Line with Track Rod Pivots.
- You show Shocks separate from Springs, Coilovers simplify installation, So I would use that (As most of us do)...
I know someone will see things I donīt...
HTH.
