Thread: Car from scratch...?

Tweet

When we were racing go-karts (40" wheelbase), we found that the ideal front to rear was 60% on the rear. I don't know of anything that corners like a race kart. Take a look at the Formula 1 and Indy cars for wheelbase and weight distribution in a full-sized car. I would think they would be the standard to build from (mid-engine).
Here's a link to one of Foyt's cars. They have mistakenly used the word tread when they meant track.

Here's a link to one of Ferrari's Formula 1 cars (F2005) that shows 3050 mm (120")

Thnx Tech!!!
Looks like 120 inch wheel base and a 57 inch track width is the hot ticket.
Now on to suspention,I figure independent rear is going to be the best for handling.
They list the suspention as double wishbones with a push rod....whats a push rod suspention?I know the wishbones are A arms,whats the push rod..a sway bar?
I also see some torsion bar suspentions too ,whats the advantage to those?

Ok I see the deal on a pushrod suspention,looks fairly easy to build.
The bottom is a pull rod.
The top is push rod.
Whats the difference other than design,I do not see where there would be a difference in handling.
It looks like the torsion bar replaces coil overs on the shock.
Would this design work with a coil over instead of a torsion bar,torsion bar looks big and heavy.
Just change the torsion bar to a pivot point?
