TUFFZJ

Need to know if there is ANY different between an big ass ZJ brake booster and a small XF brake booster??? want to put a XF brake booster into my ZJ as it would more nice than the big ZJ one...

Yeah that's why I wanted the XF booster for the clean and small looking and i was going to used a wilwood master cylinder too... In my head, it would look very nice together Looks like I have more thinking to do!!!! Thanks Guys for the help

i know it will bolt straight in, but need to know if there is any different with how it would worker??? as the zj are a bigger car and four wheel disc brakes and the xf are smaller car??
