Anthony Guarnieri Sets the NASA Mid-Atlantic TT4 Record at VIR in a TL-ONE G35
On Sunday, October 18, 2026, Anthony Guarnieri (@ag_g35) drove his VQ37VHR-swapped Infiniti G35 to a 2:03.403 at Virginia International Raceway, setting a new NASA Mid-Atlantic TT4 track record. The previous record of 2:03.990 had stood since 2018. The car runs our TL-ONE coilovers for the 350Z and G35.
The record lap
The lap came in the first Time Trial session on Sunday morning of NASA Mid-Atlantic's VIR Oktoberfast weekend (October 17–18). NASA Mid-Atlantic noted that conditions were ideal for records: a cool, dry morning around 40°F with high barometric pressure. The same session also produced a new TT3 record.

The results
From NASA Mid-Atlantic's official results for October 18:
| Result | Detail |
|---|---|
| TT4 record | 2:03.403 (previous record 2:03.990, set in 2018) |
| TT4 class | 1st, 3.450 seconds ahead of second place |
| Time Trial Target | 1st of 14, with best four laps of 2:03.403, 2:03.479, 2:03.727 and 2:03.843 |
All four of Anthony's counted Time Trial Target laps were faster than the old TT4 record, with less than a second between the best and the fourth-best. Across the whole weekend, he went under the previous record seven times.

The car
- Chassis: Infiniti G35 coupe with a VQ37VHR engine swap
- Output and weight: about 318 average horsepower and 3,340 lbs
- Tires: Maxxis Victra RC-1, 275/35/18
- Suspension: Thunder Lane TL-ONE coilovers with a true rear layout, built to order for the car
TT4 is a power-to-weight class, so the gains have to come from how well the car uses the grip it has. Consistency matters as much as one fast lap: Time Trial Target scores a driver's best four laps, so a car that stays stable lap after lap is the one that wins it. For more on how this car was put together, see the full G35 time attack build.
How the suspension fits in
The TL-ONE is a 46mm monotube coilover with a single adjuster that sets rebound damping across 20 clicks. On the G35 and 350Z it uses a true rear layout, with the rear spring mounted on the damper, which makes ride height and damping easy to adjust at the track. Every kit is built to order with spring rates and valving chosen for the car's weight, tires and use, and ships with its dyno sheets.
