Fd brakes on a fc?
 
So the brake kit I was looking at the just recently stopped making them for the 2nd gen and i was wondering if there was a way to make fd brakes mountable to the fc? I searched the forums ididnt find any similar question so someone please help?

Here you go: https://www.rx7club.com/2nd-generation-specific-1986-1992-17/fd-calipers-fc-turbo-ii-1023181/

Not
sure if it completely answers your question. Basically the front calipers interchange. The front rotors are different, so if this is a big brake kit or something that includes the rotors it probably won't work. Even if it relocates the caliper because per that thread the FD rotor is larger diameter.

how much of the brakes do you want to swap? rotors, calipers?
what brake kit were you thinking of?

you can do a ronin kit in the front and a supernow kit in the back and have a big brake kit which maintains factory brake bias

that link doeant work.i was looking at a big brake kit bc in the near future there will be a 700hp 20b going in it. I was just looking to get everything else wrapped up then do motor

I was looking at similar but was hesitant bc never heard of them and there were no reviews. But they seemed to be light. In close secomd I was looking at endless but again only fd. I like the fc body style, love it actually but so aggitated that so many items the only cater to the fd. I would like the same brakes all the way around

The easy go to for a strut car like the FC is to swap in a whole front upright/hub off a much heavier vehicle with the same bolt pattern.

This will eliminate the flexy FC front wheel hubs as well.

I think a late model Mustang would be a decent place to start.

I only mention this more much more drastic solution because a 700hp 20B FC will likely be widebody and the wider front wheels will place even more load on the flexy front wheel hubs. If you use wide wheels not only will front bearings not last as long, but any flex knocks your pistons back into the front caliper so you have to pump your brakes after corners to or you get half the pedal/half the braking.

If this is just for straight line stuff, NVM just a brake solution and/or a parachute will do fine.

now will this same solution work will coil overs. Amd going for circut racing.

BLUE TII 11-19-18 08:10 PM

Strut is pretty simple.

If you use a coilover that has both FC and newer Mustang applications you can screw the Mustang lower mount onto the FC coilover body.

I would go with Fortune Auto if I was looking for a decent cheap coilover.
You are going to have to spec the spring rates for your wheel/tire and aero anyways. Might as well mention at the same time that you need their Mustang lower mount.

Harder part is going to be the spindle lower mount to the a-arm and the steering rod end/lengths.
The S-197 (2005-2014) Mustang uses the same style spindle lower mount as the FC, but who knows what the diameter is.
S-550 uses dual balljoint front end, so you would have to use two arms like stock S-550 to the two front a-arm pivots on the FC front subframe. Maybe could use adjustable Mustang ones as the base?

I don't even know if either Mustang spindle/bearing is stronger than the FC, but you would hope so since they are 1,000lbs heavier.

FD calipers bolt on the front if you have the vented rotors. Im actually selling the FC rear brake upgrade which uses FC calipers and FD RZ rotors.

Let's try this again. I hate when that happens.

that is the supernow relocation brackets, they sell them in 16&17" versions (wheel size ) you can use standard FD rotors or the RZ rotors. Issue with the RZ rotors is as far as I remember there are only 2 rotor choices one being from mazda racing and the other 2 piece rotors- neither easily available and both expensive 2 piece are also heavier

what I have is the ronin kit in the front and the supernow in the rear, stock brake bias is kept which is important. its more important you dont end up in a ditch when you slam on the brakes due to an unbalanced braking system

So I wont need to switch out my knuckles bc this kit comes with some better ones, this is what I'll be buying for the front suspension. I guess I'll just keep shopping for the brake system. I just want something I can choose the color on that goes with my scheme. Or the brakes come in the colors I want. Gotta have drilled/slotted makes the most difference. How are those ronin and supernow brakes? My biggest thing even now as a daily, cornering is a huge priority, I push the limits of my car just on my daily commute. So I put a 700hp 20b yeah we know what happens there. Lol and yes stopping in a proper distance is just as important.

RollinHeavy 11-20-18 06:08 PM

And another thing is I dont plan to buy stock or garbage anything for this car. Money is no object for me when it comes to this car. I am just going for the best available performamce parts that fit my needs.

Rob XX 7 11-20-18 06:19 PM

ronin uses 350z rotors, supernow uses FD rotors, both have endless choices

you seem to have your mind made up as to what you want to use, no "garbage" stock stuff so both of those kits are out

I was just browsing the ronin brakes and they are sharp. But I hope there was no offense there. I was leaning more towards a bigger brake kit, just bc that way in the future I wont have to upgrade again.

You do not want to use Drift knuckles/suspension geometry on a time attack car.

The drifters take out the ackerman so the front wheels point parallel to eachother when turning to help direct the car in a drift, but will slow you down on a grip set-up where you want ackerman.

Also, the knuckles may be stiffer or stronger than stock, but the issue with the FC is the front bearings are too close together and the bearing races flex inside of the hub (not the spindle flexing inside of the knuckle).

For serious Time Attack FC parts Super Now is the company that provides parts and runs/ran a fast T/A FC.

Thank you very much, that info is tremendously helpful!

no offense was taken, the ronin kit was devolved for v8 guys who run some horsepower and track the car, a link was provided up above to a kit that will likely cost you about $3500-3700 with shipping from Japan and it will not address the rear brakes.
its your money and you seem to have a vision for the car , let us know how you make out.

my daily has 6 piston brakes with tremendous rotors but its also 4400lb car, not a sub 3000 pound FC
