I was surfing chassis builder's websites and came across this:

what advantage can anyone see from having the front shocks like this other than they are out of the way from a wreck

Weird, never seen that before!

That's the way a Wayne Larson car is set up... Jet did some cars like that also, but quit because they were having trouble getting the geometric ratios correct(I'm told). When I talked to the folks at Larson's about a new car, they said they did it to get the shock out of the way and to keep from getting them torn up... It also gives more clearance for the brake lines.

Looks to me like they are softening ratios trying to help the car roll more.

Formula cars (IRL, CART, Formula 1) all use cantilever suspensions to improve aerodynamics and to "package" the car components. I thought about doing the same thing to protect my front shocks. I'm not sure that it is legal with all sanctioning bodies.

if you go back about 10 years and find an old AFFORDABLE CHASSIS built by Mike Nystrom in St. CLoud MN. you would see he had this on his cars. nothing really new here, never really saw an advantage then either 'cept the usual dog and pony show.

Wayne Brook's car was like that at one time. The biggest advantage is getting the shocks out of the way of the travel. As long as the frames are cantilevered properly, the shocks have the same effect. The big disadvantage is when the front end is over compressed from a collision, the shock and cantilever can get into the radiator, wiping it out as well. 6 one way, 1/2 a dozen the other.

The Larson car is built that way because that is the way that Paul Cook designed and ran these cars for years before they become a Larson. If the geometry is worked out there is no difference. I think they originally did this to keep you looking at the obvious so you wouldn't catch the not so obvious.
