I haven't been able to find stock 1.8
bore and stroke of master cylinder?

also need to get front and rear brake pistons sizing

For my 1350 lb kitcar I dont' run a booster due to the low weight of car and simplicity. I am not satisfied with the feel and feedback of the pedal so
I want to talk to Wilwood if I should change the size of my master cylinder.

I do have braided flex lines and bled the system

 

I've got your bore covered.

1990-02 master: 7/8"
2001-05 Sport master: 15/16"

 

thanks Bryce
