How many miles you have now? The header thing is usually a hit or miss deal. Don't be to scared, but don't take your car high in the RPMs to often, until you get the header.
Right now I have mostly basics, and still missing some fundamentals. Lol
-4-2-1 Header, forgot who makes it
-Custom mandrel bent 2.5"mid-pipe with magnaflow hi-flow cat
-Nismo CAI
-Relocated Knock Sensor
-Nismo R-tune Control Arms
-ES mmi's
-Rob's $7 Wheel hop aid
-Motegi black "tuner lugs"
-Slotted and drilled rotors
-Chrystal Titanium O.Z Racing Ultraleggera 17x7 wheels (15lbs)
-Custom fitted 300zx clutch disk
-Custom Mesh Grille
-Nismo floor mats
-White LED map lights
nice mods, the car had 80,000 miles on it, its pretty much all stock, it has the brembo package on it but i think i need to replace the pads soon, ive looked online and havent found any for the spec, i read somewhere that you have to go to the dealership to get replacements but idk
Brembo's are nice. Wish I had them, but I got every other option besides it, so can't complain. Lol.
You can find pads on TSVB, under the vendor section, Import Car Parts. I'm pretty sure they will have almost anything you will need. Here is a link to the pads sections...

Look at the different ones, and then start googling them to compare prices. Usually they have competitive prices though.
