What are the Pros and Cons of switching to a bigger set of Brakes?

[jamal]

A 2-piston sliding caliper generates the same brake torque as a 4-piston opposed caliper given the same bore sizes and effective rotor diameter. The 4-pot has smaller pistons than the 2-pot which less force. Not coincidentally, the 4-pot generates the exact same brake torque as the 276mm 2-pots found on the 2.5RS and older WRXes. It's about 8% less than the stock 294mm 2-pots.

Plus if there was more brake force wouldn't that make the bias worse?

A few 100mph --> 70mph decelerations on the freeway got the rotors cooked and create shimmy in the steering wheel when braking. No shimmy otherwise.

First thing i tried were the Porterfield D4-S pads rated GG. They work great after a few stops, but more often than not i would catch them cold. The shimmy was still there cause i kept the stock rotors. I then replaced the rotors with Brembo plus Akebono pads. While the oem pads are Akebono too, the oem friction rating is EE while the replacement is FF. This plus flushing with Toyota brake fluid reached the desired result.

As a side note, poor mans bbk for the Camry is the current gen highlander calipers and rotors as a straight bolt on for the front. The highlander caliper is dual piston with 40% more piston area and a slightly larger rotor. I wouldnt touch the rears. I an nit sure they would clear the SE 17" wheels, but it looked promising.

Cheap and big brakes don't really go hand in hand very well.

Stoptech has a big brake kit out, but it's really not cheap. For the time being the best bet is to roll with an upgrade in pads, lines, and fluid.

You could always paint the calipers but that's along cheesy lines anymore.

Its called warping your rotors. I'm almost scared people want a BBK kit for a Camry.or know the oem pad material. Its a camry....

I've got a good idea: don't repeatedly go 100 on the freeway and slam on the brakes.

And it's not warping the rotors, it's cooking the pads so they leave uneven deposits.

This is not warped rotors. I am linking an article to this.

Anywho, why are you dissing the Camry? Both gen6 and gen7 with the V6 and SE trim will smoke the FT86 for lunch, breakfast, and dinner in most daily driving situations. 0-60 times in the Camry on 91 octane and good set of tires ranges between 5.8 - 6.2 seconds. The sequential 6 speed is not that bad either, and once the Camry is in 4th gear (1:1), game over dude.

The SE has various chassis reinforcements such as an underfloor brace, V brace behind rear seatback (no rear folding seats), and thicker side brackets. In the suspension department, it has 15% higher spring rates, 50% higher damping rates, stiffer anti roll bars, strut brace, stiffer bushings, lower assist PS pump and lower ratio rack. It also sits 0.5" lower. The 17" alloys are issued with 220 tread wear compound. What all this means is that the SE is much more composed then other Camrys.

Weaknesses: FWD (obviously), weight and brakes. Still, in daily driving situations, don't challenge a Camry SE V6 unless you want your ass handed to you.

Look at all these fucks I give about your Camry.








All of these fucks

I don't know why anyone would bother to buy a brz/frs when they could just have a camry.

Trolling a lot?

Or maybe the reality distortion field is strong with you?

I will take you more seriously when you post pics of your turbo or S/C under your hood. Until then, you are easy pickings. If you feel an unsatiable urge to defend your purchase decision in the face of a Camry, then maybe you should condider that the FT86 is not the right car for your driving style.

From what I've seen from most BBK vs OEM comparisons, the aftermarket BBK is usually lighter. If you are able to get a BBK that fits underneath stock wheels, like for like, most aftermarket BBks using a 2 piece rotor will save some unsprung weight even if they are larger. Even larger 4 or 6 piston aluminum calipers tend to be lighter than the OEM sliding caliper.

So there are some unsprung weight gains to be made just through the BBK. I'm paying close attention to Essex's AP Racing kit.

Unless you are tracking it (heavily modded, boosted, etc.) or doing for car shows, it's really not needed.

So you are planning on coughing up 2.5k grand on a set of brakes just for looks? By asking people what are the pros and cons of a bigger set of brakes it just shows your ignorance in the ability to not be able to judge why a car needs brakes. Have you felt brake fade? Do you have very sticky tires? Why are you wanting to upgrade something you have no clue over why it needs upgrading in the first place. A bigger set of brakes will not make the car stop any faster in the street , a good set of tires will. You will prob never experience brake fade in the street nor do you need the huge braking force since your street tires prob will limit your ability to stop before your brakes do.

But if you want to throw your money away on something you dont need for the street go ahead, its your cash not ours.

Hey i powdered coated my 300zx brake upgrade and my stock s14 brakes and i dont think it looked cheesy!! Its not cheesy if you do it right. Which involves taking the calipers apart.

Pics of my coated calipers on my ex s14.5

Adding 40%(!) more piston area will KILL the bias (WAY too much front bias) and give you longer pedal travel for a given level of braking. Seems like an exceedingly bad idea to me...
