Evo 8 - Brake Air Guide Install
Mitsubishi offers a set of brake air guides - plastic panels that channel more air towards the center of the front brake rotors. In theory, these should help prevent brake overheating in extreme usage, such as on track. The installation is very straightforward and should take no more than about 2 hours.
Tools required: Jack, jackstands, torque wrench, 14mm open-ended wrench, 10mm socket, 14mm socket, stubby phillips screwdriver, Dremel tool w/ cutting wheel, metal file.
Start by jacking up the front of the car and placing it on jackstands. Remove both front wheels.
This gold bracket attaches the front sway bar to the front lower suspension control arm.
The brake guide brackets will bolt onto these gold brackets.
With both front wheels in the air, you will have no tension on the front swaybar, so you can safely unbolt these two 14mm bolts, slide the brake guide bracket on, then re-install the bolts. Torque them down to 34-44Nm.
It won't be ease accessing the outer bolt, but you can push the halfshaft boot up slightly to make some more room.
Now that the bracket is in place, grab the correct air guide. Each is marked "LH" or "RH" on the backside.
Use a 10mm socket to tighten down the air guide bolts. Do not overtighten.
Here you can see how the guide will direct air underneath the car into the back center of the brake rotor.
The last step before putting the front wheels back on is remove the front undertray. Make absolutely certain that your car is secure on a pair of jackstands, then slide under and start removing the plastic clips with a phillips screwdriver. According to Mitsubishi's instructions, you'll need to remove the two small panels protruding down from the outermost edges of the panel.
LH side before removal. I used a Dremel tool with cutting wheel to remove the bulk of the material, then a flat file to smooth it out.
RH side after removal.
LH side after removal. When the panel is finished, re-install it, bolt the wheels back on and torque them to ~72ft-lbs.
