CadVetteStang Posted February 22, 2018 Author Report Share Posted February 22, 2018 I bought the C5 Corvette caliper on 14" C6 rotor hybrid bracket kit for W-body/ N-body cars from Kore3. It is zinc coated and comes with spacers and mounting bolts. Cost is $115. Tobin Knighton was my sales/tech rep and he is great to work with. The kit allows you to install C5 (or C6 base) calipers and JL9 abutment brackets on Grand Prix ( or other W-bodies) and use the 355MM C6 Z06 rotor. The only hiccup for me was that the kit was originally designed for the N-body cars and has 12MM spindle mounting holes. Kore3 was willing to enlarge the holes to the W-body 14MM size and re-zinc the brackets for $20 more ($10 without re-zinc), but I opted to save the money and do the holes myself on a drill press. Also, Tobin swapped in the 14MM mounting hardware at no extra cost so there will be nothing I have to replace after the bolt hole modification. I am pretty sure that I have Tobin convinced to produce future production runs with the 14MM holes because of more demand for W-body cars. We even talked about me waiting a few weeks for the next scheduled production run and getting them with the 14MM holes but I opted to buy the in-stock set. I also did a lot of research and chose to order 14" Mustang Shelby GT500 rotors instead of the C6 Corvette version. They are much cheaper and don't have the retarded cross-drilled holes that only work with Asbestos pads of the 60's. I found them on eBay for $68 in a 2 pack set w/ free shipping. Cheapest C5 caliper/w bracket set I found was the Power Stop rebuilds from Rock Auto. With core charges included, I was only out about $160 total for the pair after shipping, and they still have the factory raised CORVETTE logo (unlike the AUTOZONE units which were much more expensive and had the lettering ground off). I also got some shimmed semi metallic pads from Rock Auto for $8.50 + $6 shipping. This puts me at $360 total so far for the upgrade and all I have left to deal with are the hoses. For info about the big brakes, see that thread in this forum. Here is what an Eldorado looks like with 14" front brakes: Quote Click here to visit the main directory for my subforum about my 2002 Eldorado build for autocross racing: http://caddyinfo.ipbhost.com/index.php?showforum=96 Link to comment Share on other sites More sharing options...
