I have a 2013 G37x sedan, two sets of Infiniti OEM 17" wheels, one for a/s tires, one for Blizzacks (I live in snow country...)

What aftermarket things could I get to improve braking? I don't want to buy 8 new wheels and 8 new tires to move up to 18" or 19" for the Akebono setup, I'd like to know what can be done for an improvement over stock braking with the 17" wheels.

Thanks in advance for any advice / tips / warnings....

 

Centric Premium Rotors and pads w/ better bite, if you don't mind cleaning your wheels more often the Stoptech Street Pads are pretty good, Hawk HPS too.
Might contact Ken @ KNSBrakes.com let him know what you want as far as performance & budget and he should get you set up.

 

Thanks

What I'm looking for is quicker stopping for daily driving. I always want the best brakes for the shortest emergency stops.

I don't drive the thing on a track, there are no mountain roads here, and not even any twisty 'drivers roads' where I'd be worried about fade from repeated braking. I'm just looking for the fastest stops in the panic braking situations I hope I'll never actually face....

I'll drop Ken a line.

 

I would think with all season/snow tires the limiting factor is not the brakes but the tires.

 

Good point, especially if the all seasons happen to be those OEM Goodyear RS-A (Really Suck-Always), just a horrible tire, and for some reason they're expensive too, great combination

 

No, I have Michelin Premier A/S, very good tire.

 

Nice to hear

Those RS-As are best used for tire swings

 

HAHAHA tire swing, eh?

The Michelin Premier A/S is a GT type tire, not a real performance tire. It has very good ride qualities, handles well - but it's not a 'performance' tire. It's particularly good on wet roads compared to other GT tires. It works well for me, I use my G37 as more a "grand tourer" than a real sport sedan.

The roads here are incredibly crummy. Potholes, cracks, patches- it's horrible. Any kind of real performance tire, or low-profile tires, tends to rattle your teeth loose on these roads.

Actual Chicago road - Wacker Drive, downtown


I used to live in California.... now, if I was back THERE I would like to have some performance-focused tires! There are roads there where you can really DRIVE! Not so around here.

My question about brakes was really related to finding if there would be any improvements in safety to be gained from using certain brake components when it comes time to replace rotors, and pads of course. And also, it's interesting to know what the "high end" of brake upgrades would be for the 17-inch wheels, are any different calipers available,etc. - not that I would be likely to go to that level, but it's still interesting to know, and most of the discussion I've found about brake upgrades relate only to 18-inch or larger wheels. Other folks using the smaller 17 inch rims might like to know what's available to them, even if I'm not likely to go the route of new calipers.

 

Even just an improved pad will make a nice difference if your OEM rotors still have adequate thickness. But even the OEM base brakes are pretty good as far as getting the G stopped in a hurry. If you're planning on heavy braking cycles such as tracking or mountain runs then a BBK with better heat sinking and larger pad contact areas would be the plan. For smaller wheels Wilwood makes a BBK w/ 13" 2 piece rotors, but you'd probably want bigger wheels anyway just to show these off
