I like them . Even lighter than my aluminum ones. How do they fasten?

Guys there is a race team just down the hall from me at work and they lay up Carbon Fiber parts all the time. In their case they lay it up just like fiberglass, no different, looks like carbon fiber but they use normal resins. No wieght saving.
The real Carbon Fiber layouts involve alot more then just looks.
The pedals might look like carbon fiber, they might be but they could also just be fiberglass layed out.

My dad does some design and prototype fabrication for a company out in minnisota that makes carbon fiber/kevlar/fiberglass ultra-high end canoes. The way they do it, yes there is a weight savings. If I got molds I could have carbon fiber bodies made. wouldnt be cheap, though.

?? that's how carbon fiber is done, laminated w/ expoxy in a similar fashion as fiberglass (which is laminated w/ polester resins) then vac. bagged and put in an autoclave. If it consists of a carbon fiber weave then it is carbon fiber, not fiberglass.

These pedals are carbon fiber, made by debotech. Carbon fiber and a carbon composite (carbon fiber sheet w/ aluminium honeycomb inner core) is not the same.

Why are you saying they're fiberglass?? geezz....

This is how they attach to the pedals..I cut off the original ones and put these on.

yep,

them pedals should make up for all the steel tube and plate you're putting in that car.

Also, your car in its current configuration is a real gas saver!!!

I am not saying they are fiberglass. I am just saying that you can make parts to look like carbon fiber but it is really no different then fiberglass.
Carbon fiber is just a cloth, not fiberglass but acts like normal fiberglassing cloth. You can even use normal fiberglass resin on it but the finished product looks like carbon fiber but it is cheating.
The body parts the guys are producing sure look like the real thing but they are slightly heavier and not as rigid but they look good.

They do vacuum bag it sometimes to pull even more resin out.
The students have a $100,000 budget each year and they are to build the best race car they can but it must be an all new car, can salvage parts from the last years car but the design must be entirely new. I see some pretty trick suspensions.
We have 3 teams, each team with about the same budget and the work is amazing.

I was only joking about the weight savins, I replaced the pedals because the stock ones are ugly. I have more than enough compensation for the steel tubing, no heavy trailing arms, no heavy stock calipers, no heavy steering box & misc. components, no inner fenders, rad frame and misc. components, no front frame extension, no rear bumper bar & enersorbers, lots of lightweight aluminium and magnesium components...

geez some of you are really taking this all way too seriously, constantly hammering on stuff that I know...yes I know it's not finished by a long shot, yes I know the weight savings is next to nil but I'm really getting fed up w/ all the criticism....maybe I should stop posting these small updates because it attracts neg. comments... blegh.

I don't have 12 point nuts for those, the nuts are just backup..the holes in the pedals are tapped.

we're just teasing you because we like you. There is not much we can tell you that you don't alrready know so we give you smart as comments instead. You know your are appreciated here.

Thanks again for weighing your diff for me.

I'm speaking from mostly my own flustration on the weight issue. I work so hard to find 40 pounds to shave off the car then just have to put it right back on putting in a roll bar.

Those are pretty darned cool. Do you have a matching gas pedal, too? I'd be a bit worried about traction on them. Stock rubber has quite a bit of grip.

I have a 12 by 12 inch piece of carbon fiber that I was going to use to cut to the shape of the auto shift indicator on the console to cover that area. I used a 5 speed plate from Keisler. But I am going to cut a piece to go around my radio where Bubba cut too large a hole to mount another radio. It should look good and, of course, the weight savings over an aluminum plate will be astronomical!

Yes, I have a gas pedal too but I am modifying it. I drilled holes on the side so I can install a small aluminium " ridge" that way I won't slip off the gas pedal. I'm also going to have to figure out how to maintain the hinging setup that the stock gas pedal has. If they turn out to be too slippery I'm going to put some of that black sandpaper like adhesive sheet on them.
I don't have the stock rubber ones, I just had the pedal box w/ the steel pedal ends, that's why I replaced them w/ these.
