Rotor Thoughts

Bshields22 · 08-18-2015, 08:17 PM

Hey guys,

Few thoughts on this. Apologies if similar threads exists.

Looking to get a 4-set of StopTech Rotors (slotted). I know these are great rotors so no questions there.

Before I buy these rotors I want to get a few more track days out of my stock (sport package rotors). I bought the car with 24K miles on it. I have 28K now. Brakes are strong and smooth right now. Not sure if they are new rotors or not though when i bought it.

Problem: I just had them machined/turned due to slight vibration when I brake.

Although getting new rotors and pads is obviously the best way to go, is taking a Z to a track with machined rotors bad/dangerous. I know it will absorb less heat and such.

I am not the fastest guy on the track, just enjoy some spirited track days. Everything on the car is stock.

What do you guys think?

You think they were new when you bought it and you have such poor braking habits that they needed to be turned in only 4K miles?

They are almost guaranteed to be the original stock rotors. If you had them turned, get some new ones for track use.

I am no expert, but I would think you should be fine if you keep the brake use very casual. No threshold braking. It sounds like you aren't pushing the car too much anyway. For one track day that is. I would not make a habit of it. Get the StopTech asap. Better for your practice anyway.

Just out of curiosity, it wasn't when you were braking really hard was it? It might've just been abs kicking in.

It could have just been the brake pad material that was laid down unevenly. You need to heat those bad boys up and brake hard to get the material laid down properly on the rotors. Google how to bed your brakes. If you are using oem brakes with some that could have been your problem.

I've tracking with the 2 piece Racing Brake slotted brake rotors for the last 3 yrs with no problems.

You may want to consider putting high temp fluid in it and get some better pads. SS lines are a good idea too. The brakes heat up pretty easy on the Z, boiling them is no fun. While your at it put the high temp fluid in your clutch and wrap the line with insulation. It runs next to the cat. and has a tendency to boil too, ...oil cooler is the other necessary track aid to consider.

Your probably OK the first event, it's when you get use to your Z and start turning it up that the heating problems arise.

The stock sport discs are cheap and good enough. Replacing fluid more often and swapping pads for track days would provide more benifit. As long as you still have the minimum thickeness of the disk I think you should be fine. Stopping power of the sport setup if very good, it's the pad material and lack of ventilation of the rotor area that are the problems and slotted or drilled rotors won't fix that..

Unless you are racing for money and time, buy regular rotors and spend money on cooling and pads
