The Regal GS comes with Brembo brakes. They stop the car better than most any street driven performance car I have ever owned. The only problem is they squeal. My wife did not like the attention she was getting in the parking lots. They sound like my Cobalt X1 race brake pads installed in my Corvette for track day. I was joking about this with the Buick dealer service writer and he sent me the following service bulletin that states that the car comes with race brake pads. Does Buick really think customers are going to track the Buick Regal GS? It is a fun street car but it is not a race car.

#PI0676A: Squeal or Squeak Noise on Brake Apply – (Oct 26, 2012)
Subject:
Squeal or Squeak Noise on Brake ApplyModels: 2012-2013 Buick Regal GS
This PI is being revised to add the 2013 model year. Please discard PI0676.Condition/Concern
Some customers may comment on a squeal or squeak noise on brake apply. Excessive brake dust on the wheels may also be noted.
The Regal GS uses special high performance brake linings that are more prone to brake squeal and accumulation of brake dust on the wheels.Recommendation/Instructions
Dealers can replace the brake linings with the part number below.
Important: Inform the customer that the Regal GS OE pads are designed for track performance use and are required for high energy braking. The original brake linings must be put back on if the vehicle is to be driven on a track. -
Thanks for sharing @C6RAPTOR. I guess one could track the GS… nothing wrong with that. My friend’s brother does this on occasion and has tons of fun. He swaps wheels/tires before hitting up the course, has his fun (usually autocross or the like), then goes back to our friend’s garage to swap them back in one day.
Personally, though, I haven’t heard his brakes squeal except for first pulling out on a cold morning. The squealing usually ends after he comes to the first complete stop. Does your GS continue to squeal after that?

The squealing is there whenever the brakes are applied just like my very aggressive Cobalt X1 race only brake pads I use on my Corvette with StopTech big brake for track. You hear it most when driving slow in a parking lot or coming to a street stop. There are some very nice high performance brake pads on the market by HAWK, Carbotech and others that do not squeal.
I have Hawk HP SUV pads on my GMC Yukon Denali and use the Carbotech HP pads on my Corvette for street. They stop as fast as you need to stop for street. Race pads are not intended or needed for street when you are not planning on 90-150 MPH braking every 15-20 seconds like is needed for road racing. -
