Back when I was dynoing my car at Dynamic Autosports with Cameron Clark
taking pictures, I talked to the guys at Dynamics about our internet
club.  Since I used to work there, I know them personally.  They have one
of the most complete product lines for the import performance
aftermarket.  They have access to almost every performance brand in
existance.  They are also the US liason distributors of APEX performance
products, and regional distributors of Greddy, HKS, JE Pistons, Crower,
K&N, Nitto, MSD, Magnecor, NGK, Nuespeed/H&R, RB/Blitz/RSR, Nology, SX,
Turbonetics, Tokico, Koni, SSR, Work, 5Zigen, and more.  All the stuff
mentioned in the post, they have it all!  As for the price, since every
supplier has there own pricing structure and special purchases are
common, there is no structured discount from list price.    This is good:
if there is a special on a certain item you'll be given an even better
rate.  Well, enough advertising.  Here is the contact info:

Mention my name: Simon Kim.  And tell them you're from the 240sx internet
club to get the proper discounted pricing.  Also, there are some peak
hours during the day, so be patient if you get a busy signal.  There are
currently 8 phone lines, and with the vast number of clientel they work
with, it sometimes get maxed out.  They've been in business since 91 and
it's continually growing.  It's not a small time shop like other stores
mentioned in the list.  Also, they ship anywhere in the world via UPS or
FedEx.  

I hope you guys/gals take this advice and utilize your 240SX.org member
priviledges.

Sincerely,

Simon Kim aka Simonizer.
