Advantages Of The Mittler Pull Down Rig The advantages of the PDR are as stated before, ability to measure toe, cambers, clearances, and load distribution while under dynamic loading. You are able to quickly make component changes and read the effects of those changes.

The team that uses the PDR told me that its use of the machine saved a lot of time when the team gets to the track. It has more beneficial practice time because it doesn't have to guess if the fenders rub or the crossmember will hit the track. It doesn't have any surprises such as binding or detrimental toe changes to affect the truck. I guess you could say the PDR provides a certain piece of mind.

The Future Of The Mittler PDR Mike Mittler never sits still for very long. He is constantly looking to improve all of his products and invent more. The PDR is no exception. The company is looking to expand and create more models and configurations for the PDR.

One idea is to provide a scaled down version that might be more affordable to the average racer. It would have less sophistication in the way of computer controls and machinery, but afford many of the benefits of the PDR. There would be no wheel measuring apparatus, but you could attach your own lasers to accomplish that.

Another idea is to introduce the effects of lateral loading. There is a way to do this with the PDR with add-ons that would necessarily increase the cost, but also increase the capability of the machine for the high end user.

Conclusion In every machine created for the evaluation of a race car chassis, there are benefits. As of today, there is no machine that can do it all. But the Mittler PDR, in my opinion, provides the most benefit for the buck of any system I have seen. The proof is in the comments and accolades I get from the user, and it is clear that this is one very useful setup tool.
