Here's a link for people who want to know more about braking systems and upgrading them.

http://scirocco.dyndns.org/faq....html

I'm not sure how correct it is mathmatically speaking but it makes sense to me. His point really hits home since I've been interested in why my crotch rocket has brake rotors as large as my Z3's but isn't adversly affected by them. This is because of smaller calipers and master cylinder. Obviously the hand of a human being can't put out nearly the pressure delivered by the leg and foot so the pressure is increased by using a small master cylinder on motorcycles.

I, for one, found this to be a very informative piece.

You should change the title to ... EVERYONE READ THIS OR BE BEATEN TO DEATH!

And that is why I continue to get GRM magazine at my house.

that was a good read. no reasonably priced brake upgrades really seem like the answer to my problem after reading that.

"And now, the moment we have all been waiting for: It is the interface between the tire and the road that reacts to this torque, generating a force between the tire and the road that will oppose the motion of the vehicle. "

best quote. ever. Great article, i am going to save the link and sticky it in my upcomming brakes/differential sticky :)-chet

"Regardless of your huge rotor diameter, brake pedal ratio, magic brake pad material, or number of pistons in your calipers, your maximum deceleration is limited every time by the tire to road interface. That is the point of this whole article. Your brakes do not stop your car. Your tires stop the car."

He uses 88 Honda CRX HX brakes... smaller is better.

SS lines and some axxis pads, motul brake fluid.

I will, however be running 300zx brakes up front, realising that it will take more pressure(pedal effort) and whatnot, but I do experience some fade after hard runs(like say 20 minutes of hard driving, braking, etc)...

This is essentially what Chet tries to tell people every time they ask about brakes and most just don't get it. I run Z brakes up front, but I sure as hell don't expect to stop any faster. I just got tired of fade after hard runs. Remember, you can lock up your tires just fine with the stock brakes...

Sure am! Plus you're only five hours from me! :bsface

On a more serious note, to Chet, here's one....

I know wider tires improve performance by extremely small increments in concern to handling but would wider (or at least as wide as the rear instead of this whole offset thing people like to do) improve braking? The contact patch is wider and should equate into more friction generated prior to locking the wheels up.

How much so? Well maybe not more than a foot but moving the braking point further in is always a good thing, assuming you can still slow down enough before the turn, and even measured in inches I'll take what I can get to keep from hitting 16 year old kids on cell phones.

well, a stickier tire will help braking. and if the car dives forward it will exagerate the contact patch a bit...but the total area would remain the same, regardless.

Try a nice sticky tire first, then modify the widths based on taste. I suppose, depending on conditions, a wider tire, due to load transfer when braking might hold a very slight braking advantage...if any.

to be honest, a sticky tire and stainless lines(to reduce comliance and give better drive controll ove rthe system) would be your best bet.-chet

A big thing people overlook when improving brake performance is front static camber. The more negative camber you have, the less tire width you are actually putting down on the road.

Of course, zero degrees of camber isn't a good solution either. So as with most things, you have to strike a balance.

thats why cars are designed to have more positive toe when braking ;)you can try manipulating that too....but good luck finding a shop that can alter load for alignment settings.....more than just setting weight in, that is.I dunno, it rough to strike a good balance, esspecially if the car is more than 50% street driven :/
