Compared Thule and Yakima adapters for the factory rails. The Railing Foot Pack #415 renewed my long standing faith in the Thule line. The Thule adapter has a much cleaner fit than the Yakima LowRider, almost factory fitted. The Yakima seems too universal. Look for yourselves. You'll need a minimum of a 50" load bar, 58" might be optimal, or a 66". Since the Pilot is 77" wide you can even go up to 78"ers.
