something no one has mentioned on this thread is the need for a proportioning valve. the gt4 rears DO lock up before the fronts without the weight of the rear differential.

Are you referring to swapping it out with an adjustable valve or with the Stock GT4?

This recent article featuring Orido supra (Japanese race car driver who also appears on best motoring


Read left paragraph. I guess these brakes were really awesome for their time. When Toyota made quality parts

an aftermarket adjustable proportioning valve would be a wise investment.

Mr Celica if the month beams extraordinaire said those are real hard to find tune. Or wait never mind the member who had a red Celica with gtfour brakes and rear diffuser with a 3sgte swap.

I haven't had my rears lock up before the fronts but it is just over the line where it could. My arrangement may be unique to that though.
If you want a more close to stock bias then yes, you will want a bias controller. But I believe the 300mm front and 315mm rears give a more even bias to the car.

I guess you MADE the supra rotors fit berto!

the rear end has kicked out on me on 3 separate occasions.

once during a panic stop because some jackass was doing 10 mph on the highway

twice when I hit the brakes on a curved, downhill highway off ramp.


In everyday driving its not an issue. But the above situations are not uncommon. They DO happen, and you don't want the rear end kicking out to make things worse.

I'm running new Michelin Pilot sport tires, new rear struts, new rear top mounts, new poly bushings, new SS lines, new everything. Also my swaybar is at the softest setting. Therefore I don't think there is anything wrong with my setup. Proportioning valves are cheap, easy to install, and not that hard to setup. Just do a number of hard stops in a big parking lot or wherever until the rears stop locking up first. I'll be ordering mine soon and installing them over the winter.

You guys can do what you want, just be careful and be prepared to countersteer

And the car was stock when that happened, now factor in a rear caliper that is oversized for the application

Ill throw a section about it in the OP.
I can understand that not every setup is the same and just because mine doesn't do it, doesn't mean that everyone else's performs alike.

I figure if you are willing to go through the effort of doing this swap, it shouldnt be that much more difficult to plumb in a Bias Controller.

Here, in Spain, is posible to order parts from Toyota cars not released in Europe only with the part number.

In any case, you can obtain by eBay.

Yeah, but I don't think anyone in the USA is going to pay $340usd (shipping included) just for basic front rotors off of ebay...

Can anyone provide the exact measurements of the "bolt-on" rotor that we should use? I think I may have found a local shop who is associated with distributing Brembo rotors and the rotors are made here in our country. Wondering whether they could create a one off for us.

Hopefully we can resolve this and get everything out on the table.
Many measurements will be taken this winter when my car is back on the chopping block

him and I were discussing this recently
He is having trouble with the 5x114 conversion and this swap
as is Fate.
Fate should be getting back to trying to figure out a solution. He just got hitched so he is a bit preoccupied
MaskedMan said hes working on it slowly. I need to check back with him.
