UIM · Hull and handling

Aftermarket steering shaft, holder, handlebar holder, cables

UIM answers this part for 24 of its classes. 11 of those answers are permissions, with or without limits attached, and 13 are not. 5 are inferred from how the class is written rather than quoted from a rule naming this part. 8 are inherited from a parent class the rulebook points at.

This is one body's answer, not the sport's. You are bound by whichever body sanctions the event you enter, and where both govern you, you are held to the stricter of the two. The differences are set out in the rulebook comparison.

Runabout GP4 is the one class where a quick-turn kit is illegal. Everything else about the steering system is legal there.

Where it stands, class by class

24 classes, grouped by the answer rather than listed one by one, because an answer that holds for a class usually holds for every class that borrows its rules. 8 of them publish no component rules of their own and are marked below; for those, the link to the parent class is read from the categories table rather than stated in the rulebook.

No rule, this is an open class Our reading, not a rule we can quote at you. This class carries no stock clause at all, so anything unlisted appears to be open. The rulebook does not say so in terms.

Governed by the parent class 8 classes

No component rules are published for this class and no single parent class is named, so this part cannot be answered for it. That is an absence in the rulebook, not a permission.
