I'm wondering a couple things about it:
- performance difference? The stock brakes have terrible feel and IMO simply suck
- fitment of 18 wheels (esp stock, with spacers obviously).

If possible I'd like to (tape up the caliper and) test fit the front wheel of my G35S (and maybe the rear to see if the wider wheel makes a difference), and see if even with spacers if it will fit (there's no definitive yes/no, but lots of "maybe").

I'd prefer to not buy new wheels, but I have to do something about how poor the brakes are on this pig.

 

I have an 07 G35s Sedan with akebono upgrade with 15mm spacers on stock wheels it looks great/gives a great stance I think mpg suffers a little, will let you know, go to gallery and look for red g35s I have about five pics there.

 

username alto101 has the upgrade..i did the install with username 98svt last month..super nice kit,looks amazing and i know at one time there was a group buy price for around 1250.00,kit came with 14" rotors steel brake lines and 4/2 piston calipers

 

I did feel a big difference with the Project U brake pads. Much better bite than the stock pads. I have em up for sale now since I got the Brembo BBK now...

Thanks

 

I have them... well not really an upgrade.... You are welcome to test fit your wheels on my car. Just let me know.

Edit: Nevermind, I just saw the above post. Looks like 15mm spacers will do it.
