Selecting upgraded rotors+pads

[JonnyG]

A 2pc rotor or free floating rotor defintively help with unsprung weight but also defintively helps prevent rotors from warping - dissipating heat or more heat transfer. It can be say it helps protect bearings, hub and like due to heat transfer. The cores are stronger also that prevent warping - JMHO.

I've warped rotors just from going 130+ and braking on the highway - so again I would say if you drive performance cars they way they werement to be driven 2pc are a great upgrade. Shit just braking at high speed to load the fron suspension so the car rotates they help.

So the cooling effect of 2pc rotors are negligible unless the car is a dedicated track car? Idk man that sounds kinda weird. Heat is heat. Occasional track use will still heat up the wheels especially if I use better pads and better suspension because I will be more confident and pushing the car harder. So if I can mitigate the heat spreading into the entire wheel/knuckle why not? Not saying what you've experienced is wrong maybe you didn't see any difference.

Yes I'm saying exactly that.
2 piece might help cool things down a bit - but so what? If you're talking street driving, you are never going to brake hard enough to experience fade, which is really the issue with braking + heat.

The cooling advantages it mentions are a result of it being 'floating' or ventilated, which the stock rotors already are. Z1 does use directional ventilation, which would help, but... once again... the effects of this on road or mild street use would be barely noticeable.

Has your whole argument been over street use? If so, yes I completely agree with you. The use of 2 piece rotors is only seen on the track.

Yes... this OP has two threads where we are discussing brakes. He mentions noticing some brake fade during a track visit, but also says his intentions behind the build are street and occasional track.

If you are building a track car, a full brake upgrade would be one of the first things I'd do. But in regular street or even light track use, simply upgrading pads and fluids will give you noticeable gains to brake feel and performance without crippling budget.

You seem to be forgetting the important thing, which is 2 piece slotted rotors look awesome.

Oh, I got u fam!

Rotors sell well because they look pretty behind your rims.

What third party brake pads are an upgrade to the performance trim that fit stock setup? It is not clear to me.

For street most pads work the same with minor differences. I currently have z1 street pads at the front and they're surprisingly quiet and don't dust that much

One thing to point out (which I am most happy about) is the decrease in unsprung weight with the 2 pc rotors. It is a huge difference which helps the car in literally every performance metric there is. You would reduce stopping distance, increase acceleration, and handling characteristics. It’s a win in every way. If you’re questioning this then do research on how important light weight rims are with regards to performance and then look up pricing on rims that are super light and strong. Unsprung weight is the worst kind of weight there is on a sports car. To me the weight savings are worth the cost even if they don’t do anything else. Then on top of that they are also sexy ?.

I agree. My car has so much grip now that I could hurt my back if I take a turn too quickly (which has happened).
