Hey everybody, I had a question about brake calipers. I was thinking about running 300zx front brake calipers in both front and rear of my car. I was thinking I would use a larger rotor in the front and a stock size in the rear. What kind of trouble would I be asking for with a setup like this? Do you see any problems this would cause? Any feedback would be appreciated. Thanks for your time.

Maybe some car details would help people to answer more clearly ... Locost, Middy, power unit, etc.

As long as everything physically fits together I don't see why it wouldn't technically work, especially if it happens to be relatively common to increase front rotor diameter while using these calipers within the 300zx community. Although you would definitely be lacking in the parking brake department. Off hand I would guess that you'll also likely have a significant natural rear brake bias, but this can be tuned out with a dual master cylinder and/or proportioning valve.

Thanks for the replies so far. More info: alum. V6 locost which isn't it considered a middy also. Upping the rotor size is a common thing in the 300zx community using 350z rotors. I was planning on using a proportioning valve also I guess I should have stated that.

All sounds good but you may want to look into a dual master cylinder and balance bar setup.

are the brake pads large enough to fit the larger discs

if street driven a park/emergency brake will be required

You are stopping a car that will be less then half the wt. You will just be adding more unspung wt to the suspension system. If you are not racing the vehicle and even if racing "with racing rubber", it is questionable. You do not need the larger brakes, and you will not need the power brake system. But a dual master cylinder set up is always a good idea. Dave W

Ok well i'm going to have a little extra weight because I want to go awd and I also want to put a full body on it. So I will probably be heavier then the typical locost. I will also be taking your advice and will go dual masters. For ebrake I was thinking of using a hydraulic ebrake like what the drifters use. Like this.

Does that make sense or am I missing something. Thanks for the help so far.

I think some states require a "mechanical" e-brake. Hydraulic e-brakes may not be used in some areas. Russ

Just looked it up Ohio does have a law for that stating "Emergency brake: a brake system independent in application from he service brake used for stopping or holding a vehicle in an emergency or while parked." Thanks Russ for pointing that out. Looks like I will have to run something different. Thanks guys.
