Aluminum fender liners

I think we'd all agree that airflow is important. Just left the vented hood thread and realized this mod should decrease airflow through the engine and brakes, possibly increasing temps.

This mod looks cool, but has anyone thought about temps?

Engine bay temperatures, maybe minimal change. The area change is pretty minimal from the rubber versions though, and most of the air will flow goes out the back of the engine bay past the transmission anyway. If you really want to lower temps, put some hood vents near the top front of the engine to let the air that comes out of the radiator escape.

As far as brake temperatures, there's nothing to worry about. You get enough airflow to the wheel wells under the car, especially in a lifted application. Also, unibody cars and SUVs don't have any openings like that in the wheel wells and none have brake cooling issues because of it. Also, it's really hard to get your brakes hot enough to run into issues unless you're towing downhill or doing repeated panic stops from freeway speeds.
 
Yeah I don't see how these are going to flex as much as the stock covers. Don't think the body and frame should be connected with a metal plate but maybe I am missing something here. Mall crawling mod???

The body and frame don't move that much with respect to each other. A little oversize on the mounting holes and some rubber, and it's no problem. It's also <1mm thick sheet metal for the steel version, so if anything is going to break, it will be the fender liner. I assume the aluminum will have similar thickness.

They do if you leave pavement. My front bumper had 3/4" clearance from my front fenders and would routinely hit the fenders.

That sheet metal in the wheel wells is 24ga (0.6mm) and cracks from the weight of the battery if you spend any time on bumpy roads.
 
Inv4drZm did a full coverage set in aluminum last year, he wheels hard.
Seems like he didnt attach it to the frame, so no problems with body/frame flex.
Pg.54 post#804...and that would be in his build thread.
He sells some stuff, dont know about the liners though.

I have had full coverage in the rubber and no increase in engine temperature according to
the Scan Gauge 2.

...4th gens both.

Probably not a bunch of interest at that price point.

Pretty simple job for anyone with a waterjet to fill down time.
 
Trying to gauge interest in custom aluminum fender liners for the 5th gen. These are popular with the Jeep crowd but for some reason not a thing with Toyota’s. Probably because no one makes them.

RCR4WD presently makes these out of mild steel which in my opinion is prone to rock chips damaging the powder coating with resultant corrosion. I am trying to get these guys to make them out of lightweight aluminum. As you can see, these offer significantly more protection than the stock liner.

I have no affiliation with the fabricator. I just want the product made.

Price point $299 if I can get 20 people interested. This spans other models that share the same platform including the 4th gen, FJ, and Tacoma.

Simply respond with your name.

Definitely interested,
Alex
