Speedstar JDM Racing & Performance - Home

Both of these shops have been working on the z for a long period of time..
Ed @ APH is also an UpRev dealer and Bryan@APH has tuned many, many z's and g's with great success.

Speedstar is my goto shop for all things JDM.. I purchased all of my Top Secret parts from them and couldn't be happier.

They have been building up for the past few years and have definitely made a name for themselves.
