Hello Daniel, I have been taking my car to Pro Works Automotive in Matraville Sydney for about 7 years now. http://proworksautomotive.com.au/ They have worked on a lot of v35's and jdm cars for servicing and can also do wheel alignment and tyre refitting. As for tuning, I took my car to DVS TUNING and had a uprev tune done. Jez is very reputable at tuning nissan and ute platforms. - https://dvstuning.com.au/
