AE86 factory rotor diameters.

[Stealer Of Souls]

Hey... need to know what the factory rotor diameters are for AE86
Early model, most common variety.

[fangsport]

brake rotors? front or rear?

i can measure some rears if you want.

i'd be interested to know what the minimum thickness of rear rotors is as no books the brake shop has , have a listing for them.

Pretty sure they're the solid 234mm units on the front. 12.5mm thick. Minimum thickness of 11.5mm before you need to replace. Not sure about the rears sorry.

Cheers,

Paul.

all ae86's have vented fronts(every one I have seen) I have brand new fronts and rears and will measure.

[Stealer Of Souls]

Okay, I was told that the fronts are 234mm vented, rears are 242mm solid. But they weren't willing to bet on it.
I'm just keen to check out what mine should be...

there is no way the rears are bigger than the fronts they are tiny. fronts are definately vented on all 86's and solid on rears. Like I said i will measure brand new ones

[Stealer Of Souls]

Cheers ke70...

I did a rough measure up of mine (using ruler and my eye), and I think that my rears are bigger (or at least same size) as my fronts... But it was a budget, rule by the eye measure.

Pretty sure it's the other way round, rears are definately bigger than the front, I too will measure.

[Mr Revhead]

well i cant help with measurements but i can tell you the rotor part number is the same for both early and late

[JT]

Standard front disc thickness is 18.0mm, minimum thickness is 17.0mm
Standard rear disc thickness is 10.0mm, minimum thickness is 9.0mm

This is according to the Toyota AE86 Workshop manual.

I'll measure the diameters when I get home.

[nzae86]

The standard front dia is 235mm
The standard rear dia is 230mm

[Stealer Of Souls]

Okay... So was there a rear set of brakes that were bigger? I'm guessing that there was or I wouldn't have gotten given 242mm as the size of the rears...

[Mr Revhead]

not as far as i can see. there is only one part number for rear discs through out the entire model range/production run

where did you get your info from?

[Stealer Of Souls]

Huh... wonder where the other numbers come from...
Anyone else done the measurements yet?

[spencer]

The standard front dia is 235mm
The standard rear dia is 230mm

this is what they should be measured my brand new ones and they are the same. if your rears are larger there are a few other t-series equiped cars that had larger rears maybe a swap has been done on your car

[Stealer Of Souls]

Haven't measured mine yet... the info came from RaceBrakes surprisingly enough...
Steve at RaceBrakes said that according to his book the rears are 242mm... So that's what he quoted me for...
I just wanted to check for future reference, I'm not even planning on touching the rears at the moment, the rotors are only a couple of years (and about 11000km) old...

Cheers all...
