The website is a Joomla install (www.joomla.org) I maintain on my webserver. Joomla is an easy to use, open source content management system for running/creating a website. My website honestly needs some work, but I'm always too lazy to give it the attention it needs (rather go drive the AW11!)
To answer your questions:
1. I'll be building up the torque mounting points with 5mm steel plate as this is an area I have seen others damage with V6 installs. Just going to copy what Woodsport do for their 2GR installs.
2. Bigger brakes are coming. I'm currently looking at putting Wilwood 4-pots on with SW20 254x25 rotors for the front, and SW20 Gen3 rear calipers with AW11 254x20 rotors for the rear.
3. The aim is for a 100% street legal car, it will get mod plated etc etc.
4. I will be running 3kg fronts and 6kg or 7kg rears (depending how much the V6 affects the rear suspension. It's primarily a street car, so I'm keeping the suspension slightly soft since most of the roads I drive on are rough and bumpy.
