Trunk Racks
Joe - There seems to be as much agreement on trunk racks as there is on girlfriends. So, just find one that flips your switch, or go without. Big Bike puts out the lowest priced ones, Kury has a seperate style. Honda makes one, but it won't clear the spoiler until you modify it. In any case, one thing that needs to be done is spread the load on the trunk fiberglass to avoid stress cracks. Under the feet of the rack, put either 'star washers' or 'pyrmid washers'. That will spread the weight over a bigger area, but it will still be on the top shell. While the inner liner is out, put a 3"dia 1/8" thick foam 'washer' between the inner liner and the upper lid. That will give some support to the outer lid, and take some of the flex out of it. Last, look at the rubber seal between the lid and the box. The ends of the seal are toward the front of the bike. With the weight of the lid increasing, that seal is not stiff enough to provide a cushion when closed. Get 9' of 1/4" model airplane fuel line, lube it up, and slip it inside the seal. This will give enough support so the lid should not wear into the box. The important thing is the installation, not the brand of the rack. No matter what you do, weight needs to be kept low as possible.
Consider another alternative - a receiver hitch and a receiver mounted rack. There are 3 or 4 well made ones, and they help with volume. I have both Bushtec hitch and rack with cooler, and I am happy. Again, pick your own girl.
Sounds like you'on your way to a trailer. They work, too. Lottsa luck.
