Best Splitter for 2013 BRZ - GLTC

[smoltz]

What's the best option for a front splitter. I have a 9LR Big Wang. Track only car. Needs to meet GLTC rules.

Options seem to be ....

Racebred

I like the way this chassis mounts, but not seeing the complete data I would like to see on this as a solution.

Verus

This seems like they really have the R&D data on this, all the rivnuts seem like it could be kind of a fiddly install.

Something else?

I have the Verus. I don't have experience with others.

Pros

• Well made.
• Known airflow data.
• Reasonably good installation instructions.
• What seem like quality parts.

Cons

• A ton of fasteners to install it. The rivnuts aren't that bad fortunately.
• 99% connected to the front bumper cover and built to connect to the stock bumper. You have to figure out something else if you want to connect it to a bash bar.
• In order to remove the front bumper cover to do work, you have to remove the splitter first. (See "a ton of fasteners"
• Expensive for what it is.
• End plates and air dam are separate parts you have to buy. They don't have alternative options for those parts and they highly recommend them. I don't understand why they sell them separately. (see Expensive)
• Does not mount to the chassis. (See "a ton of fasteners")

I bought mine because it was my first foray into aero parts and I wanted to get something that worked versus trying to figure it out myself. I would actually make a template off of it and make my own if this one gets damaged.

I am not a fan of how the Verus mounts. A light off track and the fasteners don’t hold up. The racebreed is actually birch that is resin impregnated.

I am switching to a DIY setup that is just birch plywood coated with rubberized paint and using professional awesome quick release mount and support rods. 50 bucks gets me two.

Can you build two? Will pick up!

Do you think what you're building would be copacetic with the rules below?


Splitter
a. Definition: A horizontal, single-plane aerodynamic device attached to the lowest point of the front of
the vehicle, protruding forward. It is intended to divert air and produce downforce through vertical
pressure differential. A splitter shall have no vertical deviations.
b. A front splitter may be added. A maximum of 4 rods or cables may be used to support the front and/
or sides of the splitter. No other material(s) may be used external to the body to support the splitter.
c. The front splitter must not extend more than 2.0 inches past the original or approved bodywork as
viewed from above for the entire profile of the splitter.
d. No part of the splitter shall extend laterally any further than the widest point of the outside sidewall
of the front tires with the wheels pointed straight ahead.
e. The splitter may have vertical deviations, fences, etc., only if they are part of the production body-
work for street use.
f. The minimum ride height of the front splitter is 3.0 inches.

I’d have to modify the existing pattern I’m using but yes, wouldn’t be hard.
