All Star Racing League
The All Star Racing League features the ever popular SS Aurora T-Jets and T-Jet clone type chassis with vintage 60's-70's Trans-Am and NASCAR GT (Pony Car) bodies on
some of the most challenging road courses along with an occasional oval in the country along with a group of very talented HO slot car competitors.
Car Specs.
1. Base Chassis
1.1 Only the copper T-jet chassis from Aurora, Dash, ThunderPlus from Model Motoring Inc. and Wizard are legal.
Pickup shoe hanger plates may be bent.
1.2 The rolling chassis axle, armature, and drive pinion shaft holes may be opened up slightly for increased clearance.
1.3 The Truck hole cannot be utilized in any way. The chassis may be trimmed slightly (no more than .010) to allow for crown gear tooth clearance.
1.4 There shall be no modifications to the chassis other than what is listed above.
1.5 No bearings, bushings and shims. Spacers are permitted on the axles.
1.6 Gear plate rails may be cut or sanded only for the purpose of lowering the body and shall only
be cut or sanded to the level of the top surface of the gear plate.
1.7 The gear plate clamp may be bent (but not cut or otherwise altered) to improve fitment.
1.8 Brush springs may be adjusted only in their original configuration to change the tension on the
brushes. The brushes may be dimpled or a corner may be altered only to prevent the brush from spinning.
1.9 Guide pins shall be original design, must use a full guide pin, guide pin hole may be countersunk
for body screw, no other modifications allowed.
1.10 Guide pins shall not be metal.
1.11 Guide pins may be glued to chassis.
1.12 Guide pins may be shortened in length to accommodate different tracks.
1.13 Brush springs may be adjusted in their original configuration to change the tension on the brushes.
1.14 Brush springs may be glued to the chassis at a point no more than half the distance from
the rivet point to the commutator brush hole in the chassis. No gluing shall be allowed from
the point half the distance between the rivet and commutator brush hole to the brush hole.
2. Pickup Shoes and Springs
2.1 Pickup shoes and springs shall be solid copper and manufactured by Aurora, Model Motoring,
American Line ,BSRT (model 504 only), Wizzard, Slot Tech, Dash.or Dr. Oogan. Ski shoes are not allowed.
2.2 Pick up shoe springs may be cut (coils removed) to desired length.
2.3 Pick up shoe springs may be stretched to desired length.
2.4 Shims may be used between the pickup shoe spring and chassis.
2.5 Pickup shoe travel may only be adjusted by:
2.5.1 bending the front “window” portion of the shoe that hooks on the front of the chassis.
2.5.2 bending the hook which attaches to the chassis’ copper hardware.
2.5.3 bending the hangers on the chassis into which the rear hook of the shoe connects.

2.5.5 The "step" in the pick-up shoe must remain intact and be unaltered, except that only the first
bend in the step, (Bend #2), may be changed slightly so that proper "pick-up shoe" to "rail"
contact can be achieved. No attempts to "flatten" the "step" are allowed. The area between
(Bend #1) and (Bend #2) may be "flattened" to achieve better contact with the "rails"; however,
(Bend #1) must remain as stock. (Bend #1) may be adjusted back toward the chassis to allow
the shoe to hang on the chassis nipple. The front vertical slotted portion of the pick-up shoe
may be bent to limit shoe travel. The rear hook portion of the pick-up shoe may be bent to limit
shoe travel and adjust shoe tension. The chassis' copper pickup retainer may be bent slightly to
improve electrical contact

body, the upper edge of the top-plate, minus rails, cannot be above the top of the body as
measured at the rear of the top-plate. (i.e.: The horizontal top of the gear plate (base) cannot
protrude above the rear window opening). A rear spoiler is not considered part of the body.
8.11 Wheel wells may be cut for tire clearance. Front and rear wheel wells may be opened up for tire
wheel well clearance. This opening may be no larger than a 1/8-inch drill bit (.125") around the
entire wheel well and tire. Wheel wells must not be modified in such a way as to allow the use
of any other wheelbase than that which was originally intended by the manufacturer of that body.
8.12 Interior may be removed.
8.13 Car must have both bumpers and windshield. Bodies must be fitted with all of the
manufacturers original or exact-replica bumpers, heads, rollover bars, etc. in their stock
locations. The front windshield and rear window must be clear plastic and may be glued in place or molded in, and must fill the frame. Tape windshields
