I am new to the modified forum, I usually post in the street hobby stock forum. There seems to be a wealth of technical info in here on suspension geometry.

So here is the question, what are the differences between an impala spindle and a pinto spindle? As far as height (bJ to BJ), steering arm length, SAI, and track width?

We are building a camaro front clip sportsman car (3 link rear) and had planned to use impala spindles. I understand some of the modifieds are running a pinto spindle. We are using a chassis geometry program to design the suspension. Any help would be appreciated. Thanks

I cant really tell you much except that the Pinto spindles are strong. I dont think I have ever heard of any breaking and rarely hear of them bending. If they get bent it was a pretty serious hit, like a direct wall hit.

I do know the steering arm is shorter. but thats about all i know. we have always ran the pinto spindle on our mod so never really looked at anything else.

Use the metric Impala spindle with the Camaro stub. The better geometry is worth it. The Pinto is too short. It's a proven piece and very durable. I'll be doing this to a Sportsman car in the next couple weeks for a friend.

Good luck,

I have bent alot of Impala spindles on my Jet car, run pintos on the Hoffman. Never have bent a pinto spindle. Just my experience, and I **** and hit alot of things.

The metric spindles are too short bJ to BJ for what I am doing. Anyone know the dimensions?

The "metric" spindles you're thinking of are the montes, cutlasses, etc. The "big" metric spindles are off '77-'96 Impalas and Caprices, virtually identical to the '70-'81 Camaro/Firebird, but lighter. The Pinto spindles are 1" shorter in overall height than than the above mentioned spindles. You can use raised roll center BJ's(top and bottom) on the Impala's, but I believe only the raised roll center upper on the Pinto because the spindle height is roughly 1" higher on the Pinto's. The Impala spindle is fairly tough, but the Pinto is way tougher. As far as steering geometry, you CAN make both of them work with aftermarket tie-rod assys. and bump steer adaptors. 7-3/4" overall height on the Pinto, 8-3/4" on the Impala/Caprice/Camaro/Firebird.

Thanks for the help guys, for the geometry I am after I need a tall spindle, so I will stick with the impala. Saves me from scouringn the junkyards for a pinto!
