PREFACETo enhance the sa fe ty o f p a rtic ip a n ts and sp ec ta to rs at iMSA- sanctioned a u to m ob iie races and to provide fo r the o rderly co nd u c t o f events requ ires adherence to these rules, the IMSA CODE, here ina fte r set fo rth . A il IM SA license holders and m em bers agree to com p ly w ith these IM SA ru les, as they may be am ended from tim e to tim e , w hich rules, as in terpre ted by IMSA, govern the co nd u c t and o rgan iza tion of a il IM SA-sanctioned events. The 1984 IMSA CODE supersedes ail previous e d itio n s of the IMSA CODE as w e ll as a il am endm ents thereto, and sha ll rem ain in fo rce and e ffe c t excep t as am ended as provided herein, u n til superseded by pub lica tio n o f the next e d itio n of the IM SA CODE.

forewordThe 1984 IMSA CODE takes effect on its publication date.

These rules establish for all participants the standards governing the organization and conduct of I MSA-sanctioned competitions.

The main body of rules changes very little each year. This section defining relationships, politics, administrative procedures, rights and privileges of competitors is consistent with world practices and it evolves quite naturally.

The section on automobile rules tends to provoke more controversy and interest, since many manufacturers as well as private competitors are affected by even the slightest rules changes. As always, IMSA has tried its best to be responsible, consistent and even-handed in this regard. IMSA’s car rules reflect the experience of a marvelous cross- section of car owners, drivers, engineers, officials and race organizers.

As always, we have tried to maintain a clarity of style to avoid fuzzy meanings and avoid misunderstandings.

The most successful contestants are the ones who best understand the rules and how to use them, i urge all IMSA members to read them carefully so that together we can continue putting on the most promotabie and enjoyable events.

Ail the best for a safe and successful season in 1984.

JOHN M. BISHOP President, IMSA
