I bet I can answer those, he likes the stances but questions our suspension platform compared to European design, and at one point he was considering after market strut/coil combo, because of the valving/damping and full travel.
As far as the IC, the stock IC is fine at stock turbo levels, because it flows within its efficiency range, a bigger turbo would need more air. However the stock endtanks are known to come apart at higher than stock boost levels, unless your secure them. The PW is a very nice IC and eye candy, and I know originally he planned on more power but currently his build is pursing other directions
We'll see how close I was, and what he actually says, lol
