Right inside of the license plate flap are plenty of tubes and the wing mounts.
Here you can see that most of the OEM unibody is still present. The A-pillar, shock tower, and door frame are all there, but have been extensively modified.
This is the front suspension. Since the car was converted to AWD and needs to use slicks probably three times the width of a stock tC tire, the front subframe was re-designed and fabricated from tube. The suspension components are extra heavy duty and fit for a small tank. They know Chris likes to go into turns extra hot! The Scion also has race car style torsion swaybars and sports ultra baller custom Penske shocks all around. Penske is conveniently located in Chris' hometown of Reading, PA.
Here is the super baller spec Weismann transmission. It's an AWD, sequentially shifted, 1000hp capable transmission that costs a bundle. Weismann is known for all kinds of gearboxes including F1, LeMans, speed boats, Pike's Peak, and even the McLaren F1 supercar.
The Scion has Brembo monobloc 6 piston calipers in the front and Brembo monobloc 4 piston calipers in the rear also. There is ducting at all four corners.
