GT35R (not HTA86) comparisons/videos below

Dyno graph comparison (stock heads vs. IAG built heads, 272s) to illustrate how much IAG Stage V heads flow; no confounding variables because boost was kept the same as well as the turbo and all other parts of my setup.

Re: 2008 World Rally Blue STI - keepin' it simple

Robotvoice: I'll take some pictures over the weekend but 30% is a perfect balance between blocking out UV and not looking too illegal!

RMG: I got the lip 6 months ago for $230 shipped but now they are going for $160 shipped on ebay.

subydude: Thanks! Pleasure doing business with you guys :D
