Lexus IS BMC size

[Shakotan_Aaron]

Ive been googling and searching but im yet to find a answer.

I need to upgrade the master cylinder, Lexus IS200/300 and also IS250/350 look like they may fit my application, outlets are in aproximately the correct sport and toyota seems to use a bit of a common size with the brake cylinders.

Anyway i have no idea what bore size these have. I looked on the latest version of the ATAP website which lists HEAPs of BMC sizes but nothing for the lexus IS models.

Thanks

7/8" on my IS250

really? thats tiny. My research leads me to believe that IS250 and 350 are the same size, and the 350 has 4pots on the front....

thats actually smaller then what ive got, which is 15/16" - 23.8mm
