Pinto Car Club of America

I am building a 73 Pinto to autocross in SCCA class EP. This Pinto was formerly a Road race car in the late '70's early '80's ICSCC.
At a hill climb this year (Larison Rock - Oakridge, Oregon) there was a guy with a 66 Mustang. This was a pretty well sorted race car as he took the new hill climb record for a production based car. :2fast4u: This is a hill climb that has been run for over 20 years! Anyway, he had traction bars that connected from from the chassis below the rear floor to the rear axle. When I asked him about them in reference to using them on my Pinto he called them Under-links. He said that on he Pinto you could install them on top of the axle, cut a hole in the floor pan and attach the front mount to the floor inside the passenger compartment (Over-links). This would allow you to get the car lower. Any body ever used bars like this? Is there anything I should know before I cut holes in my floor to install these? This car has a factory chassis and a six point roll cage. THX.

I put them on my 71 with out any problems.  They did not seem to help or hurt traction or ride quality.  To be fair, my engine did not have enough torque and my tires were too wimpy to wrap up the springs.  I got the ones made by Spearco part number 5111 (they probably no longer make them).  From first glance it looked they would bind up the suspension, but it moved okay.  The best I can figure is that they rely on the rubber wrapped around the leaf spring at the axle connection as a pivot point.

I do not see how they would help lower the car.  They would gain some road clearance as opposed to using slapper bars but I doubt you would need that type of traction control on a hill climb road race situation.  They probably do locate the axle more accurately.
