StopTech SportStop Drilled & Slotted Brake Rotors - Best Price on Stop Tech Sport Stop Cross Drilled & Slotted Rotors for Cars, Trucks & SUVs

I'm thinking of getting these rotors. But they seem to come in 3 sizes 320, 330 and 350mm. I believe my stock rotors are 320mm, if I buy the 350mm rotors will they fit my vehicle? I have a 2013 g37x sedan and it's on stock 17inch wheels.
Also, did anyone have any issues with these rotors cracking?

 

355mm/350mm are for the Sport Akebono brakes - unless you upgraded those already, you don't have them. And therefore you do not use these rotor sizes.

 

can you tell me where I can get the Akebono brakes?

 

You can get them used in the private classifieds, I'll have a set available soon once I swap my current ones out with the set I'm getting painted, Tunerzstore has them along with several other forum vendors. Plus eBay as well.

 

Nailed it. Depending on the price that you get the calipers for, the upgrade is totally worth it.

As of right now, I'm $700 into my BBK (calipers, Centric high carbon blanks, Akebono rebuild kit). Still trying to decipher which pads I want to use, and then I need to purchase a SS brake line kit.

 

Also upgrade your spare donut.

 

I might just buy the stoptech 320mm rotors and hawk hps pads for about $700, the akebono set I saw costs around $1500 and it seems like they don't reduce braking distance just makes it more efficient I guess

 

If you do heavy track-type braking the heat sinking of the big rotors and calipers make them much less prone to fade along w/ more brake pad surface area. For just typical street driving your smaller X brake setup should be fine.

With the big Akebono brakes you will need new wheels too, not always easy to find wheels that clear the big calipers, even a lot of 20" wheels won't clear the fronts So to do a BBK upgrade can often end up over $3k when you upgrade everything.

Check w/ KNS Brakes and look at their basic setups w/ Stoptech pads, they're pretty good and w/ the Stoptechs your braking will improve.

 

Any particular reason you're going with the SS line kit? I hadn't planned on it but always worth additional thought.

You found some great deals, I paid a little over $800 for calipers, pads and line alone.

 

The way I see it, is if I'm spending money to upgrade my brakes for a more responsive feel underneath my pedal, and to aid in stopping power, I want to perform an upgrade on anything that will help in what I want to achieve. A SS line kit is only another $100-200 and will be nothing but a benefit for the entire braking system. I'd rather have something that's stainless steel versus rubber, but that's my $0.02.

 

Skip the cross drilled rotors. Taking mass away from the rotors isn't going to improve your braking performance.

BBK helps with fade resistance in repeated high speed braking.

 

I agree with this 100%. I've personally felt the difference between cross-drilled and a blank rotor - it's definitely noticeable. I would opt for a Brembo blank at all 4 corners, however Brembo does not make a rotor for the Akebono BBK platform.

 

I agree, I'm not so concerned about the funds either. I thought, though I would need to double check, I read mixed reviews on the SS lines along with the suggestion to swap them out every year or so?

 

I don't see why one would ever need to change out the stainless steel lines, unless it somehow gets damaged. They're meant to be stronger and more reliable, for a long period of time.

 

That's what I thought too but IIRC that wasn't the case in all applications. But I'm also basing that on info read not experience and that can always be subjective.
