I am running around the net and I have found everything I need for a 5 lug 4 piston caliper swap on my base model 2+2 87 rx7. Well... all but the 5 lug hubs... I have searched junk yards, kragen auto parts, and auto zone but I am turning out nothing. Nada. Zilch. I am in some need of direction. Any ideas?

 

Post a for sale ad in the classifieds of this and other RX-7 forums, if you haven't already.

 

i have 2 brand new 4 piston mazda s5 calipers , loaded , frount knuckles and all you would need is rotors unless you want a set of used ones off the race car wich are made by brembo and in great shape . pm me for price

 

havnt seen him in a while, but "Triadmotors" has a metric-***-ton (thats a lot) of RX-7's and parts. look in some of the older for sale threads and shoot him a PM.

 

and now stoopid question no# 2 is there a point for upgrading the rear brakes to 4 piston or can you even do so? Because If I am doing the front from 4 lug to 5 I may as well do all of them. Don't you all think?

 

I am doing the swap from my 88 GXL (now parts car) to a base 87 and have all the parts. Nobody mentions the rotor dust shields, they are larger also. The rear brakes have single piston calipers but have vented rotors (haven't set one on the other but look larger) and the calipers are wider to handle the thicker rotor.

 

Now thats a bit of a pain... I didn't know that... but is there really a point for that?

 

What the vented rotor? Runs cooler less likely to warp with hard use.
