there has been some conjecture about how the front shocks are placed on the dallara and i have a great pic that illustrates just how they are positioned. enjoy.

Just to add to that, here is what a bare front damper looks like out of the car.

Dallara definitely used this arrangement to lower the frontal area of the nose of the chassis, but these shocks must be a real b*!ch to work on. If I am not mistaken I think March used this same pullrod design on there 1988 chassis. Also Adrian Newey used it on this years RB5 rear suspension.

yea they did. but that was also when no road or street courses were on the schedule. this current car is not suited to the current schedule. if we get to the point where we get a new car, it's going to be a very different beast. hopefully a little prettier too.

i gotta say i was surprised that newey went that way with the rb5. it does make sense though. it's lower slung wieght over all and they say thet the pullrod performs better than a pushrod.

Both designs offer their pros & cons, but the pull-rod design on the Dallara was optimized for all oval racing.

Whenever the new chassis appears I think we will see the push-rod design again. To me it just looks much easier to work on the push-rod especially if you are a mechanic on a small budget team who may have to be changing springs and shocks from an oval or road course setup in the same week on the same chassis.

By the way, the photos you have been posting penske14 are awesome.
