Hi all, my name is Goh from Malaysia and i am ver glad to know your club but apologize that i use english in this post.

I planned to upgrade my brake with RX7 FD caliper for my Mazda Lantis hatchback, the knuckle i am using is from V6 5 studs.

Appreciate if anyone could share me the info on the modification of this RX7 FD caliper to Mazda Lantis V6 knuckle (5 studs).

Thanks Phat,

Do u use bracket as the bridge to mount the caliper and bracket ? any pictures ? I am not sure if anyone using V6 knuckle for FD caliper ? does it still require bracket ? Thanks

sitnalm, if you plan to use original FD caliper and brake rotor, it can be mounted on Lantis V6 knuckle with some modifications due to the rotor hight differences. If you plan to use other rotors that have the same hight as original V6 brake rotor, the modification would much easier. However, if you plan to use bigger rotor than original FD rotor, you would need brackets.

ZY and PHAT, Thanks

ZY,
I do not plan to use RX7 original rotor because the height will cause the rim to move outside a lot. Do you mind to share the modification without bracket ?

PHAT,
the Modify & Cut you referring to is on the knuckle ?

sitnalm,
The photos above modified from original 1.8 brake which has different spec.
I'm not sure if you already have the brake rotors. In order to avoid using braket, you have to look for the rotor that has similar diameter as original FD rotor but its height is same as Lantis V6 rotor.

hi Sitnalm!

it's really not difficult to have FD3S brakes on Lantis V6 knuckles. the bolt slots are just 1 mm difference. all you should do step by step are:

1. find a pair of good condition FD3S calipers and rotors.
2. grind off the adjoining sides of caliper legs and knuckle arms by 2mm and 3mm respectively.
3. build a pair of 13mm-thick spacers that are to be inserted between wheel hubs and brake roter caps.
4. re-drill bigger bolt slots on both caliper legs and knuckle arms, making sure that now all slots are exactly precise with one another and that screws are made on knuckle arms.
5. assemble spacers (in (3)), brake rotors, and calipers to the knuckles. (fine adjusting (+-1 mm) where necessary)
6. grind off some metal parts of knuckle joints to make sure that they will not scratch inner brake rotors when making turn.
7. assemble the completely assembled brakes+knuckles to shock absorbers and knuckle joints. (fine adjusting (+-1 mm) where necessary)
8. complete the job with normal brake installation procedure.

the above mentioned steps can be used for both original FD3S brakes (294 mm rotors) and face-lifted FD3S brakes (314 mm rotors).

cheers!!!

by the way, you may use FD3S rotor with wheels with more possitive offset.

another thing i forgot to mention, you should also change wheel nuts to longer ones. (keeping in mind 13 mm of the bolts will be eaten by the spacers.)

Confirmed the instructions provided by Dache. The whole set of FD3S calipers and rotors were installed with that instructions and mounted with standard Lantis V6 wheels.

FD3S calipers and rotors with RX8 (Minor) wheels in lantis v6 too.

Thanks guys for the information and pictures .. it is really amazing that so many of you are using FD caliper.

Dache,
Thanks for the detailed information, I suppose the 2mm and 3mm grinding on the caliper and knuckle respectively is to make the rotor sit 5mm outside so that the rotor would not scratch the ball joint. Correct me if i am wrong.

By the way, i was wondering if there is any rotor with 295mm diameter and 38mm total height (22mm thickness and 16mm hat height).


Zy,

Is the original V6 rim with FD caliper and rotor your car ? it looks nice but would the rim stretch outside the fender ? any spacer needed in between the rotor and rim ?

hi sitnalm,



You are absolutely right. Still, you need to grind off few mm of each knuckle joint to leave sufficient space between it and the rotor.

For the rotor, if I may recall, you may try one of Subaru Impreza WRX, Mercedes Benz E300 (W124), or Toyota MR2.

sitnalm,
I use original FD caliper and rotor with V6 rim without spacer between rim and rotor. The rim fit the fender just fine since the rim width is just 6.5-inch. On the other words, the rim does not stretch outside the fender.

Comparing with original V6 brake, the rim would sit outside about 13mm as a spacer inserted between brake rotor cap and wheel hub.
