With a big brake kit for a FD can someone tell me how much more the caliper sticks out then the standard brake calliper, because I only have about 5mm between the wheels spokes and the standard caliper.

Cheers

It varies from kit to kit.

Supposedly the AP kits leave a lot of clearance. Stop Techs are wider than stock, but there's a template on their web site with which you can test your wheels. '99 RZ's are apparently even wider than that.

 

i was thinking of going with the ta rox big brake kit il give them a call

 

ta rox big brake kit? i've never heard of them, do you have a link to their site, or any retailers site that sells them? Only names i've heard of, and am familiar with, are AP, Endless, Project Mu, Brembo, and Alcon. . . . ??

 

I think he meant Rotax?

Holy crap, 10 pot?!?!? wtf?!?!? Is all that really necessary? I mean. . . .4 is ample, and 6 is overkill. . . . .wouldn't 10 be just dead sprung weight????

 

i have no idea mate but would be nice to know

 

Well, my opinion is that it would be excess weight. I mean, from all the GT racing i've seen, the largest caliper run is a 6 pot, and that's including the Pettit GT car, Amemiya's GT300 car (i posted pics of their setup elsewhere on this board a few minutes ago), as well as many people on this forum. For the moderate track junkie, a stoptech 4 pot is more than enough. Hell, even some speedvision cars in the sub 3000lb chassis catagory run a 4 pot. 4 pot can perform just as well as a 6 pot in certain conditions assuming all the other variables are the same.

Remember, its not the limitation of the calipers, but of the actual rotor to dispurse the heat. Thats why everyone upgrades to larger and thicker rotors, not calipers. Look at the series 1-3 FD's, and then the servies 4 and on up, it's only the rotors that got larger and thicker, the calipers still retained the 4 pot set up in front. In the rear, its still a 2 piston IIRC on the later model FD's.

Their rotors look great, especially the one that resembles the Endless 24 slit rotor, except Tarox's are a multi piece design, as opposed to the 1 piece rotor that endless has in that configuration. Other than that, I personally do not see a benefit for a kit with that many pistons. I'd say go with an AP caliper kit, and get the Tarox rotors, if you are pressed on getting their wares. Thats just my input tho. Trying to watch out for a fellow rotorhead

Anyone else, please feel free to chime in to correct me if needed!

 

Never heard of them. What do 90% of the racing teams worldwide use? AP Racing or Brembo. enuf said

RedR1 said it perfectly- Remember, its not the limitation of the calipers, but of the actual rotor to dispurse the heat.

Get some 13" rotors and vent some cold air to them and you'll have no problems.

10 pot calipers sound like something you'd want if you were in a magazine and needed the bling.

I've heard of 8 pot calipers on 15" rotors.... behind a '84 Corvette with 1000hp 210ci destroked Stage 2 Buick twin turbo race car with Hewland box.....

AP's fit under 17's.... Stoptech require 18's due to their caliper shape. I have 13" AP 4 pots brakes on mine with Ntech cold air ducting. I don't expect to have any problems with them.

Definitely I can see ware your coming from and appreciate it but iam more worried about my 5mm clearance issue regarding the wheels spoke and the caliper so in the end which ever company makes the brakes that will fit is the one ill go with.

Just to elaborate on that GNX7 said, and to give a picture to the words, you would want a vent to the brakes like this:



You can even do a home grown vent system like us poorer (re: me) people, and get the end of a handheld vacuum cleaner part (the flat part that looks like this: <l and sucks in the dirt thru the end. Make sure the opening is up front at the mouth opening of your car, rig that up to some thin dryer hose, and route it safely and securely to the back of the rotor face and voi~la, home made cold air duct to your brakes Hope this helps you some.

 

318mm rotors are small, stick with an AP Racing kit. They have the thinnest calipers of any aftermarket brakes that I know of. Any good vendor will have a brake caliper profile drawing which you can use to see if they will fit with your wheels.

 

Thanks Rynberg do you know how much more the ap caliper stick out then stock.

 

FWIW, the limiting factor for ALL of you is your tires On the other hand if you run 16x12s with 13" slicks, then we have something to talk about...
