For the 2011 season, Gary's S13 will have a tube frame rearend that is detachable. The setup is similar to the Falken/Discount Tire LS powered S13 driven by Daijiro Yoshihara in the Formula Drift Series. This new tube frame section meant that the rear quarter of the car needed to be cut off. The car is getting a set of Origin widebody quarters but they wanted an inner quarter panel. This is where Alex came in.
Alex helped with fabricating quarter panels that were basically flat with a flanged wheel arch. To help with wheel clearance, much of the wheel wells were removed. The bottom of these custom quarters were flanged so that they would blend smoothly with the current wheel arch. This will give a smooth wheel well rather than have a sharp or pinched edge that could be damage the tires.
This is the custom quarter panel.
The flanged edge on the bottom will blend with the body to form a smooth wheel arch.
A fuel cell was also added for 2011 and with this additional, a firewall was needed. The firewall needs to separate the cabin of the vehicle from the fuel cell. Gary drew out a pattern for the firewall and cut it out of sheetmetal. The firewall was beadrolled in the center to provide some additional strength to the large piece of metal. The top edge was also flanged to ease in the attachment of the firewall to the car.
Alex uses the ERCO metal shrinker to create the flange on the firewall.
Gary punched out holes with the ironworker to allow bars for the rear tube section to bolt to.
Here is the firewall before installation. Gary will continue to work on finishing up the detachable tube frame rearend during the beginning of the season. He will still be out at the early events so check them out at PARC and PGP. Also continue to check back on our blog for more updates on this build.
