So I read somewhere that the auto brake booster is slightly bigger than the manual one. I searched the recent and archived topics and one thread I found only confirmed this statement but I was wondering if anyone had any more info on this. How much bigger, benefits of using the auto one over my manual one. ect.

Thanks

Yes the auto is bigger 1/2 inch maybe.. only thing I noticed it makes pedal feel natural with 300zx front calipers.(Just like stock pedal feel) With the maual brake booster its a tad less firm..as most upgrade to z32 brake master cylinder..which helps a bit.
