I have an 82 rx7. I have converted the front to 5 lug with the big bearing conversion kit and had to do a little more modifications to get the rear to be 5 lug. I have converted the rear to an 84 with disc brakes but it still had the 4 lug. I re drilled the rear hubs for the 5 lug, but its only temporary. I had to bore out the inside of the rotors to fit the hub after i re drilled them.

My question is what do i need to do to the rear to fit my 5 lug second gen wheels. Do I need to find a gsl-se rear end and swap it out. or can i just put new hubs in the axel from a gsl-se ( to get the 5 lug hub and keep the same 84 axle) But if i do that, can i still use the old calipers or will i need to get new calipers and rotors. If thats the case i dont think they will bolt up to the axle.... Im going crazy here thinking about all the possibilities. Any help would be great.

Here are a few pics of the car as of right now, with the 5 lug wheels. Thanks for your input.

I don't really understand your question. GSL-SE axles are 4 x 114.3 PCD. Not 5 stud. They would still need re-drilling.

Got ya. It has been quite some time since i have researched all of this. I dont think they make wheel adapters that go from a 4 lug to a 5 lug, or i havnt been able to find them. If that was the case i wouldn't be able to fit the old rotors over the hubs cause they would then be bigger. The way i have it right now is i had to weld two peices of metal on the front and back of the hub, to make it bigger so i could re drill the 5 lug in. then because the hub was now bigger, i had to bore out the inside of the rotor to make it fit over the hub. It works and i have taken it on the freeway for over 1000 miles. But i dont feel comfortable going faster than 65. Is there a way to put TII rotors and brakes on a 84 axle or even on a gsl-se axle. here is what the hub looks like after i drilled it to 5 lugs and put the new studs in.

As you can see it works, but it has been a temporary fix until i can do it right

You can convert to the turbo II rear rotors. They will already be 5 lug and large enough ID to not need modification.

You will loose your wheel center bore locater since the TII rotor does not have them. You will also need a bracket to convert the caliper mounting since the GSL rotors are thinner than TII.

We have a rear kit that does the conversion as well as axles manufactured specifically for the swap.

I looked at the kit from ree speed and that seems the easiest way to go. Like i said my rear axle is a 84 with disc brakes. Does that mean it is a big bearing axle? The kit says it will only work with a 84-85 big bearing axle...so im sure mine is.

second question is on the re drilled 5 lug hubs. If you look at the the new holes drilled they are close to the edge of the hub. Has anyone heard of any problems with the hubs cracking on the outer edge where the lug holes are close too. Im worried if you hit a big pot hole all that weight and shock of the hit might crack the hub??? what do you think.

Yes 84 will be a big bearing. Might be a bit to small OD. Those lugs are close to the edge. TII rotors give you a bigger ID so the axles we supply are a larger OD.

Even converting all 4 wheels to the 2nd gen 5 lug pattern, the 2nd gen wheels have too much of an offset. If you're deadset on using them, you will need wheel adapters. Here's a couple of links that may help.

The other site I have bookmarked has been flagged for malware, it's link is listed at the bottom. Try at your own risk, but I didn't have trouble with it before. You can Google for more.

what is OD? and ID? The wheels are not from a second gen..they just have the same lug 5 lug pattern. I had to put a 1/2 spacer on the front but other than that the wheels are great. Are you saying i might need to do the same for the rear.

Do the hubs come with any type of insurance they will to crack.

od, outside diameter, id, inside diameter. Not sure if anyone insures against the adapters cracking, check their website. Biggest problem is usually using longer studs, that puts quite a strain on them. If the adapters bolt on to the hubs, then have separate threads for the lugs, those are safer and less prone to failure.
