For 2020 the NHRA has come out with some pretty significant rule changes with regards to Pro Mod chassis and more. These new rules are intended to combat some of the recent issues with parts on cars exploding and coming into the cockpits, as well as crashing and having parts and pieces coming toward the driver. The nice thing about rules changes is ever increasing safety for drivers and crews, but they can sometimes cause a lot of confusion and cost a lot to implement. There are a lot of new rules that have come into effect, but this particular video from Tim McAmis is talking about the X in the doors of all these cars, why they are there, what they do and how. There is also significant discussion about the changes that affect this area.

Here’s what TIm has to say about this video.

Continuing on the trend of new rules for NHRA in 2020, this video highlights the door X area of a chassis. Specifically, driver side door panels and how they are installed. The way the rule was phrased left Tim and many others scratching their heads on how it was to be implemented. A quick call to NHRA tech officials brought insight to the intent of the rule which is clarified in tonight’s video. Please pay attention to the full video as this rule does not pertain to all categories, but can be useful to most.
