Default Brake Upgrade

I need to replace the rotors and pads both front and rear on my 91. I am assuming that I have the STD 12" brakes. Can I just buy the 13" rotors and pads or is it a lot more involved. Also, I want to replace the stuff with quality, but don't want to break the bank. I don't race or autocross. Any suggestions?

Look at Stainless Steel Brake Co, Baer, ect there are several company's out there. I like the SSBC I have on my 89. With bigger rotors everthing has to change for clearence. None will be cheap. Good Luck. :seeya :flag

Yes, its more involved. Best route I have planned out:

Adapter brackets from Ed Salinas
Rotors from Napa
c5 calipers & hardware from Chris at Superior Chevrolet

Whats holding me back is you can't use your stock sawblades without installing spacers.

I have been using 1/2 in. spacers for over 8 years, no problems. I drive very fast and hard some times.

It can be done...and i doed it! :D I bought 13" GS roters and calipers from a forum member and the bracket from Superior. The pads are the same size as stock. I had already gotten rid of the sawblades though (and it IS necessary for clearance). It was an easy saturday morning swap. There are pics of the install/swap at my homepage (link in sig).

:thumbs: I agree with everything you said! This month's Corvette Fever has an article on the switch and they claim to have reduced 60 to 0 mph stopping distance to 105 feet, down from 126 feet with stock.

I did the swap and installed the DRM proportioning spring and based on some informal measurements, I think I have my distances down to less than 100 feet. Like I said, that;s informal, measuring between light poles :D :blueangel: :thumbs:

This is pretty much the exact route I took. Except I went ahead and got the rotors from Superior Chevrolet as well.

Here is the finished product:

Hey purplemajesty I am entertaining thoughts about a brake upgrade and was wondering how much all that is going to cost?
Thanks

It'll depend on the upgrade you're thinking of. I went the J55 13" route and "pieced" the kit together from various sources, but i've seen where you can get a full C5 type conversion kit from aftermarket sources (check the ads in the back of Corvette Fever or Vette magazines)

For the brakes alone (assuming you have already have rims with clearance), you'll want ss lines, new caliper brackets, calipers, new rotors, and new pads. All total, I have ~$600 invested in the front upgrade.

For my C5 Conversion Kit (which I still need to install), I pieced it together for about $800 (not including the rims).
SS Lines from Ecklers
Adaptors from Ed Salinas (forum member)
Brake Calipers, rotors, pads from Superior Chevrolet
The setup I went with could have been cheaper, I opted for the cross-drilled slotted GM rotors and ceramic pads. Going with Napa rotors and pads, I would have spent around $600.

This is with the C5 calipers? And you are stopping 60 to 0 in less than 100 feet? This I gotta see. This is even better than 6 piston Wilwood GN III's up front with their 4 piston Superlites on the rear (and PFC 01 pads all around). It looks like I have wasted a ton of money on my setup.

Please post a video of this when you get a chance. I want to see what I'm missing.

I have afterrmarket rims but i was wondering what the distance is from the stock disc to the inside of the wheel is needed for clearance for c5 calipers.

Here's what another forum member measured:
First, you need at least 17" wheels. Then, from where the back of the wheel meets the hub, imagine a vertical line strait up. from this line, you will need a minimum of 1" clearance to the back sides of the wheel spokes at the caliper.

As far as price, you can piece it together for $600 if you don't go with pricey rotors.

everything cost me about $450...i went with used calipers for $70 for the pair from a member in the C5 section that had them off his 670 mile 2003, and raybestos pads and rotors from rockauto. I know people say not to get the cheaper crossdrilled rotors cause they will crack but since i do not autocross or race my car at $47 a piece i will try them out. the only issue i have is i need to bleed my brakes again and adjust the rod between the M/C and booster cause my pedal has a dead zone, but it had it before i switched brakes.
