hey guise;

gonna post up the details , Q&A for the upgrade.

i've swap my ek9 brake system to a nisaan r32 gts-t 4 pot brake setup.

**spoon caliper weights 2.4kg; Piston size: 42.85 + 38.18
measurement; 240mm(W) x 135mm(D) x 95mm(H)

will post more pix soon when its ready.

Q&A
1) can we plug & play the brakes?
nope, you gotta fabricate the bracket n modify the existing knuckle

2) can a 15" rim fit the r32 rotor + caliper
nope, it wont fit; only 16" and above.

3) wat rims m i using? size?
16" R32 GTS-t rims; 16" | Offset 40 | 6.5JJ

4) do i need to change my master brake cylinder?
nope, i m currently using my ek9 master brake cylinder and it works fine

5) do i need to change my brake line/hose?
nope, i m using my OEM rubber honda brake hose/line; but u can opt to swap to a steel braided brake hose :)

6) the measurements between the 2 ek9 n r32 caliper is:-
height : ek9 100mm | R32 100mm
diameter : ek9 155mm | R32 150mm
width : ek9 210mm | R32 222mm
rotor bell/hat : ek9 250mm | R32 250mm

7) bleeding sequence
FWD is closest side to master cylinder, which is
front right
left rear
front left
right rear
this is for right hand drive cars ; thanks yo jugbugz

pic by smackey from previous rx7 thread; i didnt manage to snap a pic of my ek9. i was told that the 2 original bracket was in the way of the r32 bracket and had to do something about it. suggestion by my mech was to remove it :shocked: and i was convinced that when i move on to a 4pot i m no longer moving back to single pot :p so i had them remove n a new bracket installed.

wat was blocking the bracket??

if u see the pix below; have a look at the back of the ek9 caliper; the giant piston is in the center n if u look at the back of the r32 caliper. the rear 2 piston n the casing is sticking out.and also a partial bit of the r32 mounting is in the way too, so thats the problem there. kinda got in the way. else i believe we could have designed a bolt on mounting bracket instead of shaving it off.

as u can see.. even with the new bracket installed with bolts the machinery guys was worried that the stopping power of the caliper might loosen the bolt over time; so after bolting on; they had the bolt spot welded abit jst to be safe.

now some pix of the caliper n my rims installed.

n usually after u wash your car; the rotor tends to get a little rusty; here's where i can check which side havnt been fully run in yet;
the right side; if u see carefully; u notice the brownish color on the right rotor; thats the area where the pads aint biting yet. a little more running in to do; m i m done :)

would you be able to write up a list of parts needed for this conversion and how much better?
i'll draft a short list when i m free. kinda busy with work lately.


How do you rate them performance-wise over the stock calipers?
well;; it is a 4 pot. so yeah.. its SO MUCH BETTER.
i havnt exactly sat in a ek with spoon 4 pot b4; but it brakes much much better, bite harder, n it will literally send u towards the windscreen lul.

n currently my brake pads is all worn out; about 5mm left.

if i change to a brand new pads; i m sure this brakes will be monstrous.

lul, if i can find any 15", i'll try it out :)
