Hi Captain
Yeah I noticed those specs on Wilwoods website. I'm using a stock LS1 throw out bearing from a 98-02 Camaro. In stock configuration, that was mated to a 3/4" bore master cylinder that used 1.2" of stroke. So, using an area of .44 sq inches for the piston times the stock stroke depth, I'd need to move .52 cubic inches of fluid to get the throwout bearing to fully release per stock specs.
Now it will be great if the stock pedal with your brackets provides more than enough stroke (greater than 1.2") where I can fine tune it with a pedal stop. However, I'm wondering how much travel your setup provides at the Clovis because what if it's only something like .75"? If that's the case a full stroke of the stock pedal would never give full release of the clutch unless I got a 7/8" bore or larger. I just want to be sure I order the right master before I purchase the kit.
