86 - 91 Mazda Rx7 5 Lug Conversion 4 Piston
I have an opportunity to buy 91 MAZDA RX7 5 LUG CONVERSION 4 PISTON to replace my 1986 4 Lug. Is this a good idea? Thanks for any input you may have.

I don't know about the compatability between 87 to a 91. But I do know that the 5 lug on my stripped GXL has bigger and better brakes then my n/s 4 lug stock do. So in that sense its a good idea.

SOunds pretty kick ***. I am planning to do one ina few months. Changing your lugs also let you use 15 or 16 inch stocker wheels. Which is easier to find nicer tires for. I also hear that the 4 piston front brake comes with steel brake lines. Do you know if you will need new master cylinder??

I misspoke. I have an '86 and the conversion is from a 90. I believe I said a '91. I never considered the master cylinder thing. Does anyone have an input about that. Thanks again

The swap is simple plug and play on the front. Just make sure you get the brake lines for the 4-pot brakes.
The rear brakes are a pain because you need to change the entire spindle assembly.
The master cylinder is not an issue.
See my webiste for more complete instructions.
Good Luck!

Is there a reason everyone says to get the front lines from the 5 lug car? I replaced my factory 4 lug lines with new 4 lug lines, and they were plug and play with the TII hubs I have up front now... Got about 1500 miles on them, haven't crashed in a fiery manner yet.
The master cylinder is different between the two setups, little larger on the 5 lug/4 piston I believe, but my 4 lug base model master cylinder feels fine, but I also upgraded to better fluid when I did it.
I'm still waiting on my rear half (front had to be changed due to a siezed caliper) but as it's the same calipers as the 4 lug rear, I see no way in which that will effect the pedal feel. And, FWIW, I can lock up all 4 wheels at will, even with my cheap (temporary) brake pads.
