BBhook installation for naked rear cars with modified heat shields in place
I just installed Sector 111’s BBhook on my ’06 Exige. I had thought about doing this late in 2010 at the same time when I changed to an over-the-diffuser exhaust but did not (had been using S111’s Boomerang hook at the time). At that time, along with removing the exhaust to be replaced, I removed and modified the exhaust bay heat shield for the “naked rear” set up and left the U-bend heat shields in place.
The consequence of installing the BBhook many months later meant that I would have to remove the diffuser and exhaust so that I could also remove and modify the exhaust bay heat shield for installation of the BBhook. The BBhook attaches directly an area of the rear sub-frame that is covered by the corner of the exhaust bay heat shield.
Trimmed the heat shield so the tow hook could mate directly to the frame (picture below);
Folded the U-bend heat shield partition tab over horizontally, because it was binding on the bottom of the BBhook (picture below);
Made a surface mounted grommet to secure the rear corner of fender liner (its mounting hole was taken by one of the BBhook tow hook fasteners). I did this by pressing the fender well liner mounting hole onto /around the nut of the BBhook and then pushing on a rubber compression bushing (plumbing use) over the nut and fender well liner, sliding a small washer over the top, and then a nut finger tightened (see picture).
The net result is that the BBhook is now installed with exhaust heat shields in place and the fender liner secured and mounted flush to the sub-frame.
