"If" the 350 has the same sized rear disks as a 300 but the bigger front rotors then they would address biasing by either: 1. Rear caliper piston area (bigger pistons = more effort from given line pressure) 2. Master cylinder reap piston area (smaller piston = more line pressure for a given pedal pressure 3. Combination of both This I dont know. Anybody? L8r E
I also agree with the fact that standard brakes should do the job just as well as many larger kits and that once ABS kicks in you maximum brake or stopping power has been reached....but then what tyres do you have etc. I have just done a brake upgrade on my zed with GTR calipers and Stoptech 2piece slotted rotors reason for me doing this is that n/a calipers you can't run any dogbone adapters for larger brakes etc... New set of quality rotors $400... GTR rotors $500 (I got them cheap), new pads to go with the rotors $120. If I was to buy larger skyline calipers/rotors or TT zed calipers and rotors, I only had to spend another $300 to step it up to GTR Brembos. You can have a great upgrade in stopping power with new slotted rotors and quality pads... but I didn't want to do this to then think ahh I should have could have. It's basically down to how much you can afford to spend on brake upgrades and what will satisfy your needs driving style. Matt.
What are your thoughts on this bit of kit from coz then? Thoughts? You can opt for better pads if you wish.
350Z rear brakes are bigger than z32's, pretty sure they are a 322mm rear with the brembo caliper and larger pad area too. but getting back to z32, what sort of driving do you do? and what made you feel that it needs a brake upgrade? if it's just street driving then you will be fine with a good set of street pads F&R, seeing as the rest of your brake system appears to be well maintained. spend the rest of your upgrade money on better tyres. As said, the zed brakes are fine from the factory for normal street driving. If you start cooking them at the track then you may want to upgrade. if you are getting confused by all this, try not to put too much weight on people's subjective opinions of big brake kits sending them through the windscreen etc, stopping distance numbers and decel rates are more important. there was a post on another forum a while back where a member compared stopping distance and decel from stock brakes to the upgraded 324mm rotor (standard caliper) using the same tyres. ended up being pretty much the same.
Bigger brakes will not get you that 'through the windscreen' feeling. Most of this has already been mentioned, but I'm going to reiterate and voice my opinion. The limiting factor while under braking, is *usually* the tyres The only exception to this "usually", is when you are on track, and the brakes start to overheat, and you get brake fade. The MAIN reason for upgrading to huge rotors, calipers and pads, is simply to reduce fade. There are a couple of other minor advantages of upgrading to huge brakes. 1. if you go from a slide caliper, to an opposed caliper, braking feel with be vastly improved, which then means driver confidence can increase, and therefore stopping distances can be improved on more easily, by the driver, because the driver is not perfect. But under ABS, they will, in theory, both stop in the same distance. (eg commos have twin piston slide calipers on the front and single piston slide on the rear, s13s have single piston slide all round, Z32s and 4 piston opposed front, and 2 piston opposed rear. in case the lingo varies on this) 2. initial bite of a bigger brake is stronger, so this means for the first 100ths of a second, while the caliper pressure is building, and brake pressure is ramping up, the decel will be better. But this of course depends on the piston dia., pad surface, rotor surface, BMC dia., brake lines, number of pistons etc. Conclusion? As long as you can lock up the wheels, getting bigger brakes will not improve decel, UNLESS it improves the brake balance, in which case you will probably get an improvement on paper, but zero improvement in 'seat-of-the-pants' also upgrading to bigger brakes messes with the ABS (and ESP if applicable), the bigger the volume change in the caliper, the more it will mess with it, to the point where it might not unlock your wheels, if you are locked up.
