It's not the wrong place to ask, but of course you'll receive a somewhat biased opinion.
I've produced kits for this car now for some time. The parts and pieces put into service here are the same as many of those on other kits TCE offers. Similar kits have been in use for many years on that rival big GM car for over 7 years.
The Marauder presents but one very large problem for the BBK (that's Big Brake Kit) in that the stock wheels offer very little room to fit such product. For that reason we have had to make some concessions to the parts in use and can only offer you the 1.10" wide rotor and narrow six pot caliper for this vehicle due to spoke clearance. Wider rotors (for more heat) and larger caliper can be found on the Impala and would be preferred if there is room in your wheel package.
TCE offers two kits- 13.1 and a larger 14" kit. Only the smaller fits the stock wheel and the larger kit is also the wider 1.25 wide rotor.
TCE does not offer other kits or stock replacement parts- rotor or pads and such. Only full replacement front and rear kits. All with fixed mounted multi piston design calipers. No 'floaters' found on other kits.
Comaring parts is difficult. We can discuss the pros and cons of each if you like. However the first issue usually comes down to cost and fit. Which is the 'best' is hard to say as each of the kits have their own values. But again; if you stick with stock wheels you have the first limiting factor. In this case you can have a larger rotor (14") in one kit with the floater, or a true six pot caliper and it's benefits on a smaller (13.1") rotor....
Comparing stopping is equally difficult. The same vehicle must be used, same tires, same conditions and same pad compounds. TCE works hard to provide a propery biased platform and offers a vast selection of pad compounds to enhance your kits use (street, open track, drags etc) and can also make further changes on a custom needs basis. (for example a caliper change to fit the 1.10 rotor if you have other wheels)
The primary benefits of the BBK come from fade resistance, improved pedal feel and response time. Stopping distances are seldom altered to any great degree as adhesion is limited by tire grip.
I believe TCE is still the only company to offer a true rear BBK that offers you a combo of larger rotors and properly matched four pot calipers as well.
I drive my car all year long, no matter the weather
