Driver’s rear wheel well. I made a very solid corplast structure to fill in the bumper gap behind the wheel, which improves the OEM rear undertray.
Passenger’s rear wheel well. I did the same job, but this time I gave good space for the exhaust pipe and muffler. When I first modified a car’s underbody, I had covered the whole exhaust with aluminum flashing. I didn’t exactly feel any issues, but it was a gamble of carbon monoxide poisoning and overheating. This time I’m leaving it open. There are two 10mm bolts in the frame rail, so I used those for mounting.
A laid-back photo of the ensemble. Both structure are as solid as the OEM undertray, and I did not make any holes into the unibody.
What’s next? Rear extension/separation edges? A diffuser?
Time will tell.
