AWR has a big rotor kit that you can use with the stock calipers:

However, the stock brakes are just fine for street/autocross and light racing such as SCCA IT and EP classes. The big brakes are more for high-level racing like GT, and you would probably want racing calipers and hydraulics at that point. Here is a better lower-budget option for street/autocross use:
- Stainless Steel DOT brake lines: Corksport or Mazdatrix
- Brake pads: Hawk HPS or HP+, EBC Redstuff or Yellowstuff, or Porterfield R4-S
- Brake fluid: Castrol GT LMA or ATE Super Blue / Typ 200
- If your rotors are worn, you can replace them with low-priced Brembo plain vented rotors, which Tire Rack usually sells for a pretty good price.
- If your calipers are old and crusty, your local brake shop can rebuild them for a decent price.

other models work as well but require fabrication, such as the evo IX brembo brakes.

This is what I've been running on my car for the past 2 years, track and daily duty.

This is the front kit only, so you will need a proportioning valve, or CorkSport's FD RZ rear brake upgrade.

i think i'd rather go with the modified brembos but that is a cheaper alternative as a DIY bolt on sort of setup, but both require rotor modifications still.

you can usually find a full set F+R of the evo brakes for ~$500 but then the brackets need to be fabbed up as well as rotors modded. in any case i don't think there is a way to get it done for less than around $700 minimum for any big brake kit, focusing on the fronts.

Big breaks



Surfs up dude.

Yup, there's no easy way around it! I figured I would throw it out since he said his budget was around 1.5 grand. I also don't think it's needed over blanks and good pads unless the car and driver exceed the capabilities of the factory brake system.


t2boostbrotha - does this car see the track/auto-x often?

after all that will the car stop well and be well balanced and proportioned or will it just look cooler?

the EVO is a 4 door sedan versus the FC which is about 1k lbs lighter, the brakes are larger all around so i would sure hope that it stops better. Brembo is one of the world leaders in braking technology also and are found on some of the highest end production vehicles.

tlmitf

EVO IX - Curb weight - 1,310–1,490 kg (2,888–3,285 lb)

FC3S - Curb weight - 1,393 kg -1,191 kg - (2,625 lb- 3,071 lb)

I dont see a big difference in weight here.
The stock FC brakes are very capable, good fluid and pads are all you need.
If you cooking brake fluid (spongy peddle) try a higher rated fluid. If thats not an option, get some better disks with more vanes.
If your out gassing the pads (rock solid peddle) then you need to upgrade pads.

At best there is 600lb difference between the FC and the EVO IX - and i have seen the FC calipers next to the EVO items. The evo items are chunkier, with bigger pistons - but they cant swallow much bigger diameter disks, however they can take slightly thicker disks (which can give you better ventilation)

Personally i wouldnt bother with the EVO IX upgrade on the FC or FD

RotaryEvolution

the FC seems to be the prior to those figures as i have never seen an FC creep up on 3k lbs before unless it is with a full tank and driver, the EVO seems to be the latter of the figures as i have my doubts a 4 door car with all the bells and whistles weighs anywhere near under 3k lbs.

at any rate, the EVO uses brake technology that is almost 20 years newer. as cars are more up to date and drive faster, brakes and suspension become better as well. the FC brakes were some of the best for it's time, but there is obviously better out there now on even mid-range sport vehicles.

but you're right, unless driving hard for long periods the stock 4 pot brakes still do a great job even by today's standard but with brakes, bigger IS still better.

my comparison was a slight exaggeration but by comparing the 2 sets of brakes you can obviously see which will do a better job for any real competition performance as an upgrade.

anyways..

the issue really seems to be getting the proportion of braking correct, this is why using the stock calipers actually works so well

No denying brembo makes good stuff, but I know from reading builds it seems people dont always get the results they were hoping for once they start swapping calipers

RotaryEvolution

iTrader: (30)

the problem mainly is that the stockers are only inadequate in heat dissipation due to rotor width and venting for true track duty. the proportioning of the stock brakes is actually spot on, so with bigger brakes it takes less effort and can cool easier but brake bias is affected by overpowering the fronts(this is the second part of the issue as i generally do not see people upgrade the rears, the booster, the master, an adjustable proportioning valve, etc).

all in all, better brake ducting would probably be more suitable for a fix.

but the question was big brakes, to which people have replied.

tlmitf

I would rather an old volvo 4 pot caliper over the new EVO caliper
I remember there being a set of volvo calipers that had two brake line connections, and could be setup to pump the brake fluid back to the reservoir, rather than letting the fluid sit in the caliper and thus eliminating the problem of boiled brake fluid.

Personally i rate brake feel being very important - and big calipers with huge fluid content doesnt seem to give a very good feel.
Sure they are going to take longer to fade out, but whats the point of stopping all day if you cant hold it right on the point of lockup? I love late braking. Sliding up the inside of someone under brakes, knowing that the other guy is going to be cursing because he didnt brake late enough (or he just out braked himself because he cant feel whats going on)



Still, its all just opinion and personal preference. What works for me may not work for you - a race car (and lets face it, you need to be racing to fade out the FC/FD brakes) is about getting everything working for the driver - not some random bloke on the internet!

so again is it to look cool or to actually perform well- this is the question, and people swapping out calipers without giving much thought as to whats involved besides bolting them up will be on the wrong path

RotaryEvolution

well, it should work better for straight line braking but for braking hard through a corner it will likely be overpowering with bigger brakes fitted. everyone has different goals, so as to avoid the argument as to which is preferable, it is for everyone to decide on their own what they need and where.

boiling brake fluid is not something i wish on anyone, usually you have to change your underwear when you realize your brakes are inadequate(yes i have experienced this and it is not fun thinking you are about to die).

tlmitf

Boiled fluid is preferred over gassing the pads!
At least with boiled fluid you can still get some braking - when the pads a gassing, you cant get the pads to touch the rotors!

Still, there is a point there - so far boiled brakes have cost me one motor, and a few sets of undies

RotaryEvolution

iTrader: (30)

depends on the extent, i have had the fluid so hot that the fluid escaped the pistons so there was zero braking. now that is fun!

granted that is an extreme example which would be like riding your brakes in a downhill event.

why so many people are apprehensive about offering brake kits, too much liability involved
