First off it's beautiful, so great, amazing job.
Handles very realistically it seems. First few races I thought it was very loose and I was sliding around (found out it drifts beautifully w/o handbrake, scandi-flick, or down shift w/o rev match, or throttle blip)... Then I realized I was driving it the fiesta ST, (basically WOT and taking everything at at 100%, late braking etc..). I tightened rebound in the rear, dropped 2PSI in all 4 tires and dialed myself back to like 80% aggression (early braking, using partial throttle as needed) and it RIPS! 4 laps in and I'm now faster than the ST at the top gear track (around 1:23 right now, plenty to go) I feel like its going to settle in around the 1 minute and high teens, which for me is on par with high HP AWD cars.
It would make a mean rally machine or even gymkhana rig if it was given an aggressive handbrake (i know that not the point of the build) LOVE IT. 5 stars.
