| Track | Class | Sessions | Typical gap to class best | Closest |
|---|---|---|---|---|
| Road America (4.05 mi) | EP | 8 | +5.685s (3.80%) | +4.390s (2.92%) |
| Virginia International Raceway (3.27 mi) | EP | 8 | +5.797s (4.60%) | +5.524s (4.44%) |
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.

#39155 from Bryce McGuire · Not recommended · Minutes (2025-12 Fastrack)
Thank you for your letter, but this request is Not Recommended at this time. The performance potential of the 2.8L BMW's in EP
has proven to be adequate.
#38806 from Bryce McGuire · Not recommended · Minutes (2025-09 Fastrack)
Thank you for your letter, however, the Flat-Plate Restrictors that are currently applied across a variety of BMW's in EP are
accurate to current intent, with respect to power output, competition weight, chassis differences, etc. between them.
#38490 from Bryce McGuire · Rule change · TB 25-07 (2025-07 Fastrack)
In EP Spec Lines, BMW Z4 (03-05), add to Notes the following:
“52mm Flat Plate Intake Restrictor.”
