I have stock size brembo x-drilled/slotted rotors and stock calipers on my 4th gen. My dad has an Aston Martin that was unfortunately in a fire a couple years ago and is about to be sold as a parts car. I was thinking about what parts I could use on my car while I was working on his car the other day, and the first obvious thing were the front 4-piston (maybe?) Aston Martin brake calipers. This is a somewhat older Aston (80's) and it had 15" wheels but was a heavy car. So it looks like they used a big caliper to get a lot of clamping pressure on a rotor that looks similar in size to my stock size brembos. So my question is, why wouldn't that work for me? What are the obstacles? Can they be made to fit? Issues with mounting brackets? Getting proper sized brake pads? Brake lines? Or is it just not feasible...

The main obstacle you will have with those calipers is that how you plan on mouting it? You are going to need to create a custom bracket for it. 2ndly is will it even work after you create a custom bracket in the sense will it clear the control wheels and rotor with ease?

It almost to the point all that work just for 4piston calipers is not worth it, might as well get a 300zx 4piston caliper from a 90-96 and that bolts right up and all you have to do is get 300zx rotors and mill them down 4mm. No custom bracket or anything needed. Probably much cheaper in the long run than messing with trying to get an Aston Martin caliper to fit.

Yeah, I agree. But they are free, I have a friend who can fab a bracket for free, they may be similar or better than Z calipers in performance, and um.. they are from aston martin But that is why I was asking. I don't know much about the clearance issues involved when going to a bigger caliper. But I do know that this caliper was on a rotor that looks very similar to a maxima rotor (sizewise and thickness), and sat behind measly 15" wheels. What do you mean when you say control wheels? I was never quite clear on why the Z rotors had to be milled 4mm. Can someone clarify this for me?

I mean to say will it clear the wheels with the offset. Control word was a mistake. Why the rotors had to be milled, well if you try to stick the caliper on as it is, it wont clear with the 300zx rotor. Only way to make it clear is to mill off 4mm from the radius. That way the caliper will clear the rotor with it being mounted on the stock caliper mounting bolts.

Yea it would be nice to have aston martin calipers, but if they dont have the surface area and performance of a 300zx caliper then it may not be worth it. If it fit behind a 15" wheel, the caliper might be smaller than the 300zx caliper.

I suggest you keep all your old hardware and give it a shot. What do you have to lose if the new ones are free?

well i dont think it would be worth it either. you prolly wont see alot of performance gains from me, more resistant to heat. and if the pistons are alot larger then stock you might get a crappy feel in the brake pedal. with the 300ZX calipers this already happens, what if the Aston has even bigger calipers making it worse> ugh.
