I know in the past adult carts were not allowed at local events. Has that changed to allow the adult single speed and shifter carts??????
Until this weekend, the only carts I’ve seen in person have been the local dirt carts. I wasn’t too impressed with them. Moroso Motorsports Park has put in a cart road race track. We are set up 20 yards from it. Those things HAUL A!!
Tell me we can’t run them, cause it looks like it would be some fast fun on an autocross course for a reasonable price. Hitting a cone might be a bit of a pain tho….
A 125 shifter kart usually runs in Nashville and gets FTD. Most of our sites and course designs do not accomodate a kart other than the 5hp junior version. We have turned away karts at WBHS for instance. The SCCA rules are:
_______________
D. The Solo Safety Steward shall have the authority to disapprove a
course or site for karts only, when there are upright solid objects
(e.g. light poles, fence posts, etc.) on the site within 50 feet of
the actual course. This does not include curbs. While safety
systems for karts provide acceptable driver protection for most
incidents, upright solid objects present potential hazard for which
kart safety systems are not well suited. This rule gives the Solo
Safety Steward the option of excluding karts without having to
declare the site unsafe for everyone. It is up to the judgment of
the Solo Safety Steward whether the course design, surface, solid
objects, and type of karts running present an unsafe mix. In most
cases, the situation can be resolved by a course design change.
KART SOLO II EVENTS
Solo II events which will have karts competing must so designate on the
sanction application. Prior approval is not required. The rules for organizing
and conducting a Solo II event with karts are found in Appendix G.
APPENDIX G - KARTS AT SOLO II EVENTS.
I. APPROVAL PROCEDURE
A. Regions conducting Solo II events which will have karts competing
must so indicate on the sanction application.
B. A post event report describing the kart portion of the event should
be submitted with the usual Audit Report Form. These event
reports will be helpful to the SCCA in more effectively evaluating
the kart program.
II. EVENT OPERATION PROCEDURES
A. Karts will not be allowed to be driven under power through the
paddock; they must be pushed either on the ground or on a portable
stand.
B. A grid area must be established that is either separated from the
regular car grid or grids karts with similar sized vehicles such as
formula cars. Traffic flow to and from the grid area must be
controlled.
C. If karts are allowed which require a push-start, such as shifter
karts, the grid area must accommodate this need adequately.
D. All karts will be run as a group or grouped with formula cars, and
not intermixed on course with full-bodied cars. However, at the
discretion of the Solo Safety Steward, the Event Chairman, and
the Chief Stewards, karts may be allowed on course with fullbodied
cars if the course design allows for safe separation, such
as the start and finish areas being remote from each other.
E. Event procedures regarding karts will be announced at the drivers’
meeting and will also be in written form for posting.
III. KART ELIGIBILITY
A. Kart eligibility is limited to racing karts recognized and regulated
by a national kart sanctioning organization (WKA, IKF, ISRA,
NSKA, etc.) with a maximum of one 125cc engine. 125cc shifter
karts are the fastest karts allowed.
B. It is the responsibility of the kart entrant to provide the rules to
which their kart is eligible and prepared.
C. Specific designation of classes is at the discretion of the hosting
region as long as the above eligibility requirements are met.

Uhh, Scott, I hope you didn’t type all that. If you did, you have too much time on your hands being retired and all. A simple no cause of the 50 feet minimum instead of the 25 feet minimum for a car would have been fine. I have the rule book back at the house, but thanks.
Looks like a F500 or some other kind of formula car would be a better bet. Able to autocross the courses we have and road race it. Like I get to road race the ITC car I have now.
