Can anyone assist me in converting my 85fb to a 5 lug in the front.

 

What about the rear?

 

There are a lot of threads here on the forum on how to do this. You either have to redrill the current rotors (not recommended) or buy/make a new kit. This includes creating/buying a spindle adapter and then using gen 2 RX-7 brakes (rotors/calipers/etc). There is a common kit originally from RE-Speed (no longer in the RX-7 business). This kit has been duplicated by several people. One of those sells them on the big sales site every once in a while. Cost about $450 for all the parts the do the front and rear. You supply the gen 2 brake components.

I have a complete front and rear setup in the forsale section that includes everything already put together. It's not cheap. I also have a spare set of gen 2 front and rear brakes (hub/calipers/rotors/etc) that can be used with a kit you buy.
