I just installed Stop Tech slotted rotors with Hawk HPS pads on front of my G35xS
but did not change the OEM rear rotors or pads. Will I encounter any issues. I did the install 2 months ago but have only driven 1000 miles. So far brakes feel good though I've found the harder you work them the better they feel.

 

I did the same install myself last week but I did all 4 pads...The only thing that sucks in your case is now you will be doing twice as many brake jobs lol.

 

I know what you mean the car begs to be thrown hard into corners. The way I see it better brakes mean faster driving

 

No you are fine. Front and back can be done separate (whenever they wear out).

 

Thanks for the info. It will be a while before I change the rears. The G is in my garage. I've been using a Honda Civic to commute to NJ. I decided to cheap it out, besides the gas my Bridgestone S-04's would be replaced every six months. This gives me more of a reason to look forward to the weekend as if I needed more!
