I looked around a bit and I didnt see anything talking about how much (or if you can easily) upgrade to Brembos. Does anyone make a kit for it? I am just trying to get an idea. Thank you.

 

Yea its pretty simple to upgrade to brembos. Question is how much are you willing to spend?

 

you can change it out yourself, what year is your car, I assume it is post Brembo's
I changed mine out myself, I did a one for one swap with a girls 2003 G35 for my 2005 non-Brembo's she didn't care because she ended up selling the car anyway, I or-course also gave her 1k cash to sweeten the deal
everything should be a one for one swap the bolts for the rear calipers are different and will need to be swapped along with the new Brembo calipers
it's been a year or so since I did this change, I'm pretty sure I did a small write up on it though,
