Revamping the Rx7

i just used the adapter fittings and regular tee. Had the local hose place make the metal connectors. Its all connected and finished at this point. I have one 90 degree fitting enroute so hopefully i can make the last hose, the mountings tabs and connect the fuel lines and be done with the fuel crap in full! Would be nice to have it flowing and leak free. Hell, i could worry about the important stuff, like will the car run?

alright so i have some minor details (well not really minor).

A quick synapsis:

Front suspension is from a 2nd generation Rx7. So that leaves me with two brake options. The 4x114.3 hubs/rotors that run single pistons or the 5x114.3 4 piston aluminum calipers on about an inch larger rotor. I have the 5 lug option in the car right now.

The rear stuff is from a GSLSE and is a vented 4x114.3.

So with that, I can do the following:

A. Swap to the 4 lug brakes up front and thus match the rear.

B. Try and find a rotor that is dimensionally the same as the 5 lug rotor up front but in 4x114.3 *not sure how to even go about that*

C. Get Moser axles for the rear in 5 lug and run the FC rear brakes as well (most costly option [axles 350, brake adapters bits, 200])

or i can just run mismatch stuff for the idaho rally and hope nothing goes too wrong.

Or D, using 4 lug front hubs with 5 lug rotors and calipers. It has been done and documented.

I'll try to find the link when I get to a real computer.

One hole would be the same, so you would have to drill 3. Kind of like what Adam used to do for rotors on the rear of the corolla before he went full volvo set up. He had to make a jig to do it, but its another option.

Nah, just redrill the rotors and stuff. http://www.aaroncake.net/rx-7/4lug4potbrakes.htm

Yup, that was the link I was looking for.

Just make the jig out of a used 5 lug rotor? Flip it upside down on top of your 4 lug rotor, line up the one hole and have at it...

Why do they have to match front to rear? Just carry two spares, even easier.
