big brakes fd front

[LRP]

my front pads and discs :confused:  are comin to the end of there life, so very shortly im lookin to change them and i dont want standard there poop!!! i want to retain the standard calipers and maybe fit bigger discs with a spacer on the caliper has anybody had any experience with this and is it worth it

If your not changing the caliper then cant see point in getting bigger disc\'s. Pad will still be on same surface area,a nd cooling wont be that much affected, you would be better off getting the same size but a better quality disc, and better compound pad.

Surely increasing the size of the disc and locating the caliper further from the hub will increase the effective leverage exerted by the caliper, as leverage is a function of the distance from the pivot point (i.e. the hub).  Also the larger surface area where the relocated pads act on the bigger disc would increase heat dissipation.

Just my thoughts, feel free to correct me if wrong

The leverage would be increased but the surface area would be the same as stock if you keep the stock pad/disk.

On the subject of the original question, how could you get a bracket to fit that would allow you to keep the existing caliper? The caliper is bolted to the hub at at 90 degrees to the disc. You wont be able to get a bracket to extend it out in line with the disc would you? If it was bolted in line with the disc i.e in line with the back and front of the car then you would be able to put a spacer in then...

Seen it done on other cars, here is a pic of my mates S14A with stock calipers and brackets mounted to large brakes.

[Donato]

a pic of the back would be nice to see how the bracket actually works..  

[Kieron]

IIRC the kit come from APEX Performance. Give them a call.

[Donato]

Doesnt matter that much, i was just interested in how the bracket works...

i have big brake plans of my own involving the shiney red porsche calipers i have ready to put on..which involves a different bracket.

[Christopher]

Kieron, is that the stock caliper or one from a 300ZX or Skyline as some people are doing this.

ive also seen this done before, on mx-6s/probes (same PCD incidently) they upgrade to 12" discs using the standard caliper //www.rr-racing.com make the kit and sell the discs. they also do 13" discs with calipers for mx-6s

this is a picture of the bracket they provide taken from their site

Ah ha! thanks mate, now i can see how it would work.  :yes

Curiosity satisfied until my next daft question..

[deanflowers]

NO WORRIES it was just luck that i remembered where i had seen it before,

i feel chuffed that i was able to get something right

Respect. :wiggle

I was meaning the surface area of disk that the pad acts on will increase with a bigger disk (bigger circumference and  greater rotating area clamped by the pads) and therefore you\'ve got a bigger heat sink/radiator to aid braking.

I get what you mean now.
