I think that I've done a comprehensive search regarding the current state of the market regarding fender flares for the Sidekick.
EGR stopped production of Flares in 2007 and I haven't been able to find any suppliers who still have an inventory.
There are flares that can be found on e-Bay for the special Vitara models that were sold non-US but those models had modified gas filler doors and the flares will cover part of the US spec door. Modifying US doors is a major task.
Flares are manufactured in Iceland for the Sidekick but I have not been able to find the manufacturer despite following several leads.
J.C. Whitney sells flare material and several Sidekick owners have posted that they have used it but none have posted details as to which type they used and I haven't been able to find photos of the final installation. Reading reviews on Whitney's website I really don't want to drill holes to install them because of rust concerns.
Other "universal" solutions include Phoenix USA, similar to J.C. Whitney, and other fiberglass, carbon fiber and other material universal kits found at
www.bodykits.com that look like they would require a fair amount of work.
Can anyone add to this discussion?
