Guest Posted July 13, 2003 Share Posted July 13, 2003 Thats right! 12" Front Rotors on a reatta, MY reatta. I just finished the coversion and boy does it look good. I put 12" Crossdrilled Silver Cadmium plater rotors on the front and stock 9" Crossdrilled silver cadmium rotors on the rear. The 12" Conversion in the front was a lot easier than I thought it was going to be. Everything from the donor car bolted up, except where the braket bolts to the car and that just required me to make the hole larger. As of now the calipers are painted red just so I could see what the color looks like. Im planning to have a guy powdercoat them for me. Ive included some picture links below of the front and rear setup. Rear Rotors Rear Closeup Front Rotors Front Closeup Front Closeup with Rim I must warn you that this WILL NOT work with stock rims. I have 17" Aftermarket rims. If anyone is interested, let me know and I can guide you through it. Link to comment Share on other sites More sharing options...
2seater Posted July 14, 2003 Share Posted July 14, 2003 What was the donor car? I installed 16" American racing rims and the little bitty brakes look pretty small. There is just over 1.25" clearance from the rim to the caliper so a two inch larger rotor and the appropriate caliper bracket would be just the ticket. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" /> Link to comment Share on other sites More sharing options...
Guest EDBS0 Posted July 14, 2003 Share Posted July 14, 2003 Fantastic!!OK! Stop teasing.Tell us about the donor car and what parts are required.What pads did you use? Link to comment Share on other sites More sharing options...
Guest Greg Ross Posted July 14, 2003 Share Posted July 14, 2003 And then the surplus front rotors and calipers can go on the back, hmmmmm Link to comment Share on other sites More sharing options...
Rawja Posted July 14, 2003 Share Posted July 14, 2003 Very cool.... :::Patiently awaiting the details of the upgrade::: <img src="http://www.aaca.org/ubbthreads/images/graemlins/cool.gif" alt="" /> Link to comment Share on other sites More sharing options...
Guest Posted July 14, 2003 Share Posted July 14, 2003 Okay, in exchange for this info, Hal has to help me with my turbo project; GM has to help me with the 5 speed going with it, and ED has to help me with general stuff relating to both. Heres the info:Donor car -- 1998 Oldsmobile IntrigueThe bracket and caliper came from this car along with the pins and dustboots. I got them extra cheap since I work for a parts warehouse that deals with AC Delco. The rotors are KVR rotors that I had crossdrilled and plated by Pure Performance over in OH. Although the order was delayed, Im REALLY pleased with the rotors. The bolts came from Lowes/Home depot. Pads are cheap pads from autozone for the 98 Intrigue. (Dont want to chew up the rotors too fast. Would rather spend 18 bucks for pads often than buy new rotors alot)Unfortunately the old bracket and caliper will not bolt back up, so keep this in mind when doing this mod. This is because you have to drill out the holes where the bracket mount to the car. Its a 14mm bolt, so I used a 14.3mm drill bit. Also, I dont know how well this will fit on other rims. I think 16" rims might be do-able, depending on the space between the rim face and the caliper. Its quite a large caliper.I am willing to put together some packages and shipping them to those interested, as it will be cheaper due to my discount on calipers, brackets, pins and dustboots. (Trust me, I saved about $250 because of this.) If anyone is interested, let me know. Link to comment Share on other sites More sharing options...
Guest EDBS0 Posted July 15, 2003 Share Posted July 15, 2003 Excellent work!!!<div class="ubbcode-block"><div class="ubbcode-header">Quote:</div><div class="ubbcode-body"> Pads are cheap pads from autozone for the 98 Intrigue. (Dont want to chew up the rotors too fast. Would rather spend 18 bucks for pads often than buy new rotors alot) </div></div>You might want to rethink the pads. If you can believe Performance Friction their Z rated pads last longer, stop faster, dust less and help you grow hair and are kinder to rotors than the lower performance pads. Hope this link works. PS: I have used KVR Carbon Fibre Metalic pads with great results. Their Canadian office is about 2 miles from here and a friend Max who ownes his own business is in the one end of the same building and he owns an 88 Reatta often has it out front.The Intrigue with 12" HD Brakes runs on 16" rims. And to think I have new Yokohamas with less than 4,000 miles on the stock 15". The stock Reatta rims likely wont fit but did you try them? What about grinding some off of the corner? <img src="http://www.aaca.org/ubbthreads/images/graemlins/confused.gif" alt="" />What would the Front calipers, brackets and hardware cost. I would likely use standard Brembo rotors at $61 each don't worry if you can't supply.I hope that the bolts from Lowes are of a sufficient grade to be strong enough.

2seater Posted July 15, 2003 Share Posted July 15, 2003 Ahh so! Bartering are ye? <img src="http://www.aaca.org/ubbthreads/images/graemlins/smirk.gif" alt="" /> I would be happy to share my turbo info. when I get it operating to it's potential. Are the brakes on yours different than mine? The front rotors are listed as 10.24" and the rears at an even 10". Do you know how much larger the new caliper is than stock? The weird thing about my rims is they look almost as large as 17" although they are 16" and there is a lot of room inside. Link to comment Share on other sites More sharing options...
Guest EDBS0 Posted July 15, 2003 Share Posted July 15, 2003 Napa shows ... Item#: UBP86641 Attributes:Attributes: Rotor - Front Diameter: 11 59/64'' # of Bolt Holes: 5 Bolt Circle Dimensions: 4.645'' Discard Thickness: 1.209'' Warranty: Limited LifetimeWould love to get them inside the stock rim.Perhaps by drilling out the mounting holes towards the centre of the hub might get a few extra 32nds" Link to comment Share on other sites More sharing options...
Guest Posted July 15, 2003 Share Posted July 15, 2003 I dont have an exact size on the new calipers, but I can get some info. The bolts are the exact grade as the dealership, accept @ lowes they are 2.50 and at the dealer they are 22.50. I will get a full quote for each item and the package deal, that way you can change rotors if you like. Hal, Im pretty sure the brakes will fit your 16in rim, but you might wanna check the clearance, not of the diameter, but of the width of the rim. I will post links of measurements ASAP.

padgett Posted July 16, 2003 Share Posted July 16, 2003 Had a set of Performance Friction replacement pads on the Bonneville for about a week. Took considerably heavier pedal pressure and wife could not push hard enough for max decel (she once entered an e-z-pass lane and the arm did not go up. Stopped with arm about 4" from base of windshield, seemed less than a foot in front of my face. Tires were squeaking but not sliding. She knows how to stop a car).In any event replaced with a set of premium Raybestos pads and was back to normal. Called PF but they did not seem to believe me.

Guest EDBS0 Posted July 16, 2003 Share Posted July 16, 2003 I have them on the Riviera now and yes they do require more force AND a bit of heat in them. They can make you nervous on the first stop of the day. The KVR Carbon Fibre Metallic require much more force and heat. My brother-in-law who moved the Reatta the first thing one cooler morning NEVER drove it again He said "The dash and guages went crazy and there are no brakes". Also had them on my SHO with cross-drilled rotors and on my favourite mountain hill in Vermont they worked perfectly. Later I went down the same hill in a new dodge Caravan and there was heavy black smoke coming off of the brakes at the bottom stop sign. Kept on driving onto the interstate and the rotors cooled without warping. However I was certain that there were no rubber dust boots left on them.

Guest Posted July 16, 2003 Share Posted July 16, 2003 Yes, performance pads operate at higher heat a lot better, but once warm, damn do they work. Im thinking about going to carbon fiber pads, but they are expensive. Oh well, Im still searching for that info you guys wanted. Been busy with work and comming home, eating an sleeping.
