@Talleywacker what's the name of the FB group?
Well... the stock 00' R caliper is designed for the stock cobra/GT rotor which is 332x28mm or 1.1" thick. You can the ATS caliper and stick to that but to me the performance upgrade is in the rotor which is what takes the heat... The XTS caliper using a GT500 which is 355x32mm or 1.25" thick rotor is the more ideal of an upgrade. I think the Chris Salmon Shim Kit works with both. A guy on the FB group "Clem Palacious" had some information on this on april 8th. The issue with the GT500 rotor is the fact you have to run 18" wheels.
I find my 13" stoptechs to be extremely powerful and lock up my street tires very easy so my 13" brakes are not the limit... the tires are. My uncle told me he would still be able to lockup the brakes using 275/40/17 Hoosier A6 tires meaning the stoptechs still are not at their limit. My long term goal will be to buy another set of fenders and do flares and run 315 square setup with the Hoosier A7 tires.
If you can stand on the brakes and the brakes lock (or abs engages)... you need better tires. If you stand on the brakes and your not stopping you need better brakes. They should compliment eachother "based on your vehicle and driving style"
Hi. I’m Clem palacios from the FB group that installed XTS with gt500 rotors. It’s correct that Chris salmon kit work with XTS and gt500 rotors. we installed this on a buddies car when he received XTS instead of ATS calipers from an eBay seller. This will require 18 wheels. Minor clearance for with a file is need on back of caliper. A 5 minute job.
So far everything is great. I am doing my own ATS to XTS swap this weekend. I prefer the look of the XTS gt500 combo. Nothing wrong at all with my ATS brake.
I don't have any experience with the brembo pads. I've only driven my car 400 miles on the street and I couldn't even tell you what pads they are... it was a set of street pads given to me when I bought the car.Talleywhacker, what do you think of OEM brembo pads? The XTS calipers actually came brand new loaded with pads.
but yo your point I agree a good pad is needed if not it’s purely cosmetic.
Yeah, took me forever to find these then took me forever (again) to find the rebuild kit. I know the full kits are available from some outlets still but I didn't want to spend that kind of dough. Still ended up costing me $500 for the calipers, braided lines and rebuild kit when all was said and done. I'll keep you posted. I have a feeling I'll end up using these. Just been trying to get my man cave done for awhile now and all of my Terminator projects are on hold (brakes, KB Street Cage, rear seat delete, etc etc)
These guys and their 3-4 hits to get it out... it took me wayyy more effort than anticipated too but just keep going, or maybe a heavier hammer? I used a copper hammer and smaller regular one but eventually got them
Are the taurus rear calipers only worthwhile if upgrading the front brakes? Or would it help reduce brake dive with stock front brakes?
I do find it odd that the ATS caliper was designed for a 300hp 3400lb car while their CTS-V gets the 6 piston brembos for a car making 550hp and weighs over 4000lbs. I mean.... this is the only logic I have that says we probably shouldn't run to the "ATS" variant and look for something made for our cars which typically make 6-700hp and weigh 3700lbs

Then i discovered the 43mm Taurus caliper. I wonder what brake bias would be like with the 14" XTS setup, and the Baer 13.25" rear rotor with 43mm Taurus caliper? Only downside to that setup would be that the rear rotor is solid, vs vented.
It actually looks a LOT bigger in person than the pictures can convey. It makes the factory Cobra brakes seem puny.The pics of the GT500/XTS brembo setup mounted look great. I know when i initially set that up on my bench it was such an massive looking brake setup that i didn't know if it was practical. Then i discovered the 43mm Taurus caliper.
