I' converting my 86 rx7 from 4 lug to 5. I allready have the front end peices. What Do I need to convert the rear? Do i just need the hub or will i need the hole trailing arm assembly? If you could get me a list of what I need or where to go on the net that would be cool. I just found a wrecking yard over here that have some good peieces. Let me know whats needed Thanks ROB

 

You need.

2 - Front 4 pot brakes
2 - Front Hardlines (hard line into caliper, then brake line into hardline by fenders.)
2 - Front 5 lug hubs
2 - Rear 5 lug hub (great time to install DTSS eliminators!)
4 - Brake rotors, fronts and rear, 5 lug
4 - Lugnuts, 20 in total
4 - 5 lug wheels

If you are going to vented rear disk you will need the rear TII calipers.

For a proper install you should also get the TII brake booster and master cylinder.
