I bought a 13" WCF kit (Viper rotors/Corvette calipers) from another PFF member. It arrived today and I started with cleaning and painting the parts.

I will take pictures of my progress and the installation.

The boxes:


Out of the box:






After a thorough cleaning, masking off for painting:


All rotors painted:


Hubs painted:


Brackets painted:


Calipers will be done tomorrow and installation will be Monday/Tuesday.

very nice =)

Idk what it is about those rotors, but I just don't get a comfortable feeling looking at the way they're drilled. I don't see how it could be a problem, but it looks awefully weird.

I think there was a big long thread on here some time ago about this issue. Don't know what the general consensus was on the drilling of the rotors but I know I wouldn't use them.

If the center is a snug fit I would think that a couple of weak holes would not present a problem.

Kolja, what time will you be at Phil's place on Monday?

HI all

Will there be an engine swap in the future?? Hehe...

I will try.

Cool! I'll hopefully get my A/C fixed, too. The steady stream of sweat is not good for my Mr. Mikes seats! :-)

Dude, you don't mess around when it comes to getting on the ball--do yeah.

Never. I'm an "instant satisfaction" kind of guy.

Take another amazing picture to replace the one of yours on my desktop right now. I noticed your rotors looked a little small in that pic

Hey, what's the chemicals you used to clean those rotors and what's the name of the caliper paint too? Please take before and after pics.

I used carburettor and brake cleaners, a wire sponge, wire brushes, an electric wire wheel and shop rags to clean. High-temp silver/aluminum and black paint as well as red caliper paint from Advanced Auto Parts for painting.

Of course I will take before/after pix.

Ain't that the truth! I like the fact that you did this by hand. It only make you stronger.

You will definately have to report on the increased stopping power. Just cool.

I definitely wouldn't worry. The rotor is clamped between the wheel and the hub, the screws are only there to provide the clamping force which in turns results in the friction that's keeping the wheel, rotor and hub at the same rotational speed relative to eachother.
But it does look weird with the siamese holes And I do wonder why the kit uses 13" Viper rotors instead of 13" Vette rotors?

From what I was told the Viper rotors are much lighter.

I am a bit worried about braking bias on this kit. 88's brakes are identical at all 4 corners. 84-87's are slightly front biased, but this kit looks to be all about the front. That might be OK for a corvette, but for a Fiero, I would be concerned. You might want to consider disabling your Proportional valve, as now your bias is so heavily shifted by the brakes themselves. If you leave the Proportional valve as it is, you will have very little rear braking and poor stopping distances.



that'll give you a fixed 50-50 front to rear pressure distribution instead of the 58-42 front to rear the factory prop valve will deliver at max braking pressure. That should help straighten out the bias issue that this brake upgrade is sure to cause. I wish I could find hard data on piston diameters for these calipers, It would be interesting to see what kind of bias the corvette used.

The project has started...



Everything nicely laid out...

I am highly curious what the weight difference is between the original and new brake parts for each axle. Do you have either the time or interest to provide this info? TIA.

Call WCF since they're the ones who shipped the parts, but Yellowstone might know since the weight should be indicated on the package. Otherwise, I have weights for the C5 and various parts.

This is how the day ended:





Still to do:
- Move the front shock inward
- Extend the steering stop
- Install e-brake
- Bleed brakes

Clem (LT88GT) and I took a lot of progress pictures, will post later.

Yellowstone:

Looks great!

Regards,

didn't know about the weight difference. pretty damn good reason for using the viper rotors

Yellowstone:

Also, when you have the tires balanced, be sure they use the thinnest weights available if those are 17" wheels.

Regards,

David

That, and he's cheating by using a lift. Real men crawl around in the dirt and swear a lot.

Is that a stock Vette rotor or a Wilwood or some such?

Actually Kolja reads the instructions to the mechanic. It's too hot to work today.
