The panel is rigid. But it will obviously flex modestly if left un supported since it's a large structure.

 

I got mine locally from Allied plastics in Dallas.

Most places that carry dibond will carry polymetal.

 

Careful with those end plates on the splitter. I dont think thats TT4 legal. You have have a airdam that follows the outter most edge but can protrude out from it. Also those fender vents are not legal as well.

 

Same can be said of the fender vents. Hood venting only if I recall correctly.

 

Very nice. Where did you get the fender vents? Been considering options for those as well, although I notice that the Viper ACR's track configuration actually has the louvers removed and just a bare hole over the tire.

 

I can confirm that the Chinese Amazon splitter support rods are crap. I had one break in my hands when I was just bolting it on. Longacre rods should arrive today.

I was able to use rubber well nuts with some spacers to mount to the subframe drain holes at the rear of the splitter.

 

TT4 is number class so it's power to weight with modifiers for upgrades. Car is within the rules.

 

untrue. TT4 has its own special section in the 2017 rules:

2) TT4 Specific Aerodynamic Modification Allowances (if not using OEM Mod Factor): Aerodynamic parts/devices/aides shall be limited in TT4 to the following:
a) All of the items listed above in section 7.3.2.D.1) “OEM Aero” Modification Factor.
b) Vertical front air dam (5º tolerance) that follows the outermost edge of the front and side bodywork/fascia.
c) Single flat, horizontal front splitter that protrudes no greater than 4” from the vehicle. NASA Time Trial (TT) Rules 2017 v14.1 Page 12 of 71
d) Single rear wing or spoiler that does not exceed a height of 8” above the roof line, or width greater than the vehicle’s body width, or end plates greater than 12”.
e) Modified BTM, non-Base Trim Model (non-BTM), or replaced front fascia (unless specifically approved in Appendix D:
i) May have nothing attached to it other than specifically allowed items (above).
ii) May not have canards/winglets molded into it.
iii) Any item that is molded into the fascia that functions as an airfoil, deflector, dive plane, or vortex generator and extends 2" or more past the outline of the immediate surrounding fascia is prohibited. To inspect: a plumb line run across the entire surface of the fascia and bumper shall not have any such item that extends 2” past the line when viewed from above.
f) Cutting/removal of the rear bumper cover/fascia where it does not cover the rear frame/bumper cross beam.


I am currently putting my k24 frank car together while going through these with a fine toothed comb.

 

TT4 has specific aero restrictions that are not part of TT1-3. Please read the rule book before citing things.

 

Ah yes. You're correct.

We intended for TT4 originally but direction of the car ended up TT3.
