Gap is the driver's best lap in a session against the fastest lap in their class in that same session (zero is fastest in class), shown as time lost and as a share of the lap, so conditions cancel out and tracks can be compared. Typical is the median session.

Letters to Fastrack

STU GT86 Cups Car in STU

#40028 from Peter Federlin · Rule change · TB 26-05 (2026-05 Fastrack)

In STU Spec Lines, Table B: Alternate Vehicle and Engine Allowances, change Notes as follows:
"Must meet all 2022 Toyota GR Cup rules, including tires or DOT tires conforming to section 9.1.4.O with a maximum section

A specification table follows in the original; it is not shown here.

STU Parity in the Class

#39279 from Peter Federlin · Not recommended · Minutes (2026-01 Fastrack)

TCR cars are no longer in STU. Adjustments have been made and will continue to be made throughout the year.

STU 275 Tire Rule

#38983 from Peter Federlin · Rule change · TB 25-12 (2025-12 Fastrack)

In GCR, Section 9.1.4.G.1., change as follows:
"A maximum section width of 245 is permitted. Cars over 3150 lbs. may run a 275 tire with a 2% weight adder."

STU TCR Cars in STU

#38586 from Peter Federlin · Taken care of · Minutes (2025-08 Fastrack)

Thank you for your letter. Please see letter #38723 in current Fastrack.

STU Tires Used in STU

#36006 from Peter Federlin · Not recommended · Minutes (2024-05 Fastrack)

Thank you for your letter. At this time there is no evidence that this change is needed, however we will
continue to monitor data from the class. The GR86 Cup is a Spec Car and cannot take advantage of the STU
preparation potential.

STU Alternate Drive Shaft Material

#34160 from Peter Federlin · Not recommended · Minutes (2023-09 Fastrack)

Thank you for your letter. Carbon Fiber Driveshafts are not allowed in STU.

STU Sequential Shift Transmission Clarification

#29446 from Peter Federlin · Not recommended · Minutes (2020-10 Fastrack)

Thank you for your letter. The change you have requested would require a penalty.

STU Request BoP for my Car

#29004 from Peter Federlin · Rule change · TB 20-07 (2020-08 Fastrack)

Thank you for the letter. Given the rule set for STU large displacement turbo engines are limited by the
turbos allowed in the GCR. We are forced to adhere to this turbo list to maintain parody in the smaller
displacement turbo engines. This engine may be more competitive prepared in non-turbo trim in STU or
inquire with T1 committee about running turbo trim.
