It would be neat to have a thread dedicated
SOLELY to Z/28 track preparation. A pilot's checklist if you will.
This is for cars that see >50% street use (rather than dedicated track weapons). Please add your
tried and tested specs/solutions to the thread. Feel free to propose a section that builds out the checklist.
If you do not have personal experience on track with, or preparing, a Z/28 for the track please refrain from posting here. Legitimate questions from those thinking about tracking a Z/28 are welcome!
A. Necessary
1. Alignment:
Street: ...
Track (optional): ...
2. Tires:
a) Trofeo R:
Cold temp: “221 kPa / 32 psi” (Section 9.6 OM)
Hot temp: 32 psi
- "...they are designed to run at pressures around 2.2 bar (“hot” tyres), the finite adjustments depending on vehicle type." (Pirelli website:
http://www.pirelli.com/mediaObject/p...R_2014_ENG.pdf)
b) Hoosier R6 (Size TBD):
Cold: ...
Hot: 35-36 degs (my preference on other cars - to be tested on the Z/28)
c) Other?
Cold: ...
Hot: ...
3. Brakes, Pads, Fluids:
a) Pads:
i. Stock
ii. Other?
- Note: “…complete the appropriate high performance brake burnishing procedure…” (Sec. 9.6 OM)
- Burnishing: 0-60-0 mph x 25-50 runs Followed by a 10 mile cool-down drive (c/o backintotops)
b) Fluid: Sec. 9.6 OM: “...it is recommended that the brake fluid be replaced with a high performance brake fluid that has a dry boiling point greater than 279°C (534°F). Do not use silicone or DOT-5 brake fluids.
- Note: Bleed fluid completely through clutch".
4. Cooling:
a) Remove water deflector under the hood scoop
b) Sec. 9.6 OM: “...reduce the coolant/water mixture to a 30/70 mix”.
c) Add WaterWetter
5. Fluids:
a) Engine Oil
50W recommended in the manual
Recommended oil change mileage:
- I typically change oil every 4 track days (4-5 sessions of 20-30 mins/day), or 5,000 street miles. YMMV
b) Differential fluid: Change every 6 track hours
6. Tow Hooks:
a) Skylane765 (
www.zl1addons.com)
b) Other?
B. Optional
7. Data/video system:
a) SmartyCam/AiM Solo
b) Dash Logic
c) Traqmate
8. Harness Bar / Roll Cage (that doesn't destroy the interior):
a) Brey-Krause:

b) Other?
9. Wickerbill
10. Accelerator pedal extension for heel/toe
