Ok this is for the 240 guys. I am doing the z32 brake upgrade on my base model 240. It is 4 lug. I have all the parts for a 5 lug conversion...well most of them...the rest of them should be here today. But I am just curious if I will need a slide hammer to remove the hubs from my car? and also what size are he hub nuts....I think s14 are 36mm front and 32mm rear...can some one help me? Greaser...=) or anyone else with this knowledge. thanks all.
