I am not sure that you can without some modification, could be more trouble/expense than it's worth. Many people just go with the LS400 BBK from a LS400 1995-2000, and they do an outstanding job of stopping the SC. I have an extra set of LS400 front calipers that I may sell.

Or, the more tried and true conversion is the Supra TT brakes. Plus, it'll cost you almost $1200 at Lexus for a front brake service when your pads wear down.

If they have enough power to stop 1000hp Supra's at the track, they should be able to stop your SC.

It has nothing to do with stopping, but more so with cooling.

The stock brakes work fine with the right pads.

But they will overheat sooner being as how they have less surface area and dissipation.

Also, what difference does it make if the Supra has 1000hp or 200hp? Weight is weight.

It has a lot to do with how fast you can get going between turns that you then have to slow down for. Successive brake applications from 100 are going to heat your brakes far more than they will if only from 60.

(p = mv).




If you're wondering about the weight difference, Supra's and SC's are only about 100lbs apart.


I was stating that if the stock brakes on a Supra have no issues slowing them down from 160mph, road racing, canyon runs, etc. Not to mention they are quite cheaper, why not go with the tried and true conversion and stay practical?

Mainly... until your car has the ability to outperform your brakes, no need to go overboard.

Like putting a parachute on a stock Civic Si.

Agreed. I changed the brake fluid and added a set of Porterfeild R4-S pads on my car and I'm very happy with the results (Although if I recall correctly SC400 brakes are slightly larger than what the 300's got). Stock pads are meant to never make a peep and keep the dust off your wheels, which translates to poor braking performance from the factory.

nothing to do with stopping - in that case go and put some pushbike brakes on your car.

overheat sooner with less surface area - so camry brakes overheat before soarer brakes braking for the same corner.

weight has 20% got to do with it.

sc400 276mm brakes have more clamping force than 320mm supra tt brakes

sc400 have an engineering limit of 500hp
sc300 have an engineering limit of 650hp
supra tt 4 pot have an engineering limit of just over 1000hp

Lets say your car is putting down a blistering 208hp to one wheel...

You round a corner and there's exactly a ½ mile ahead before the next corner.

A 1000hp Supra rounds that exact corner moments after you.

The Supra will reach a much greater speed and still be able to stop fine way before the next corner. As oppossed to your car that cannot reach nearly the same speed in the same amount of space.

So, why do you need brakes that are better than the Supra?
