I have an '87 mr2 with warped front rotors for one thing, and bad brake balance for another. I want to be able to brake while in a turn and feel like the brake balance is close to neutral. So far if i get on the brakes in a corner the fronts want to lock and go straight. Does anyone have any recomendations for drilled rotors (too keep them warp free) and pads to even the balance out?

Just remembered, I know the weight is biased to the rear, and its hard to get weight to transfer to the front before turn-in. Now i'm wondering if what im asking is too much for just modding brakes- to brake without fade and transfer weight to the front tires, but then have neutral brake balance during the turn....

2400lbs is heavy

you don't need big honkin' heavy brakes if you don't have a big honkin' heavy car.

if you are in the tight stuff, downhill. I guess you folks are drag racers, lol. The biggest difference between most race cars and most street cars is braking. I have owned five AW11's, they, and most all other street cars are simply not made to handle threshold braking (or anywhere near that).

As I tell most everyone, you want to know how fast a car is, dont look at the engine displacement emblem on the side of the car, instead look at the front brake rotors. That will tell you all you need to know. IMO, brakes are the number one fail point in performance driving and you never have too much. If you dont have the brakes, you might as well not have all the other performance parts you have added. Ask anyone that has ever owned a Sunbeam Tiger...:cat:

Hi! I just try my new brake set-up at kingston 2008 and it is very good

a take 4 disc from a mazda 5 2007 and I machin the disc to have 11 1/2 diameter. I drill 4 hole for the stud to fit my hub.

for the braket, I modified my stock one and I put a metal plate to reinforced the braket.

I have sniper pad (carbon-kelvlar-metallic) front and rear
Goodrich SS brake lines
dot 4 brake fluide ford heavy duty
brake master brace
rebuilt caliper

this set-up help on the track and when I have the mr2bbq on the back.

88 SC
stock rotors
Goodridge coated stainless lines
Porterfield HP R4S pads front/rear
High & Tight MS brace

works FANTASTIC for daily driving and autocross. not so much for road course use, but for anything else its great.

I'd love to try some better fluid like this blue stuff people keep talking about.

Completely re-engineered the brakes to fix the balance and keep up with track duty.
Fronts are Mini Cooper S 294mm rotors with BMW Z3 calipers (30% stronger than stock fronts)
Rears are the same Mini Cooper S 294mm rotors with Mustang SN195 calipers (45% stronger than stock rears)
Master cylinder is from a T100 1/2 ton (30% lower pressure than stock)
Installed a Wilwood adjustable proportioning valve since it actually needs it now.

I made the adapter plates on my mill, when I get home I'll try and remember to upload the CAD files and drawings. Parking brake cables are not super straightforward, I had to modify the Ford brackets on the calipers and we'll as modifying cables from the mustang. They work, but it's not something you can buy off the shelf.

what exactly needs adapting? Your set up seems to be the best I've stumbled upon in the last couple days. In need of new brakes asap haha. Thanks.

Both front and rear calipers need adapter plates to bolt up to the stock knuckles. I finally found my CAD files for them, I'll upload them when I get home. Xometry is an online machine shop that I've used before to get stuff like this made, I think the plates were about $400 to get cnc machined. If you're ok without parking brakes you could do the rest for about the same amount and have way better brakes than stock for about $800.

ok so the calipers need adaptive plates, but the Mini's rotors will not need any adaptions?
