Yakima
http://fitlookup.yakima.com/
For Premier with roof rails the above will give:
Tower: SkyLine Towers 4 Pack
Front Clip: Landing Pad 19
Rear Clip: Landing Pad 19
Minimum Bar Size: Small
M4: 28 1/4"
Front Bar To Hatch: 45"
Weight Limit: 165 lbs
For LT without flush rails, the above will give:
Tower: BaseLine Towers 4 Pack
Front Clip/Pad: BaseClip 123 (B84-4)
Rear Clip/Pad: BaseClip 181 (B74-3)
Minimum Bar Size: Small
M4: 32 "
Front Bar To Hatch: 57 "
Weight Limit: 165 lbs
List prices:
$490 with JetStream crossbars (aerodynamic with T-slot)
$414 with CoreBar crossbars (aerodynamic without T-slot)
$414 with RoundBar crossbars and RoundBar SL adapter
$380 with RoundBar crossbars and Control Towers (instead of SkyLine towers) for Premier with flush rails
$59 for four lock cylinders with any of the above
Note 1: The Control Towers are an older Yakima ("Classic") product that may be used only with RoundBar crossbars. The RoundBar fitments are primarily useful for those who want to reuse older Yakima stuff that they already have (for example, if you already have Control Towers and Round Bar crossbars, you will need only to get the $96 Landing Pad 19 to install them on a Bolt Premier). Those buying new can use the CoreBar at the same price for less noise and energy consumption.
Note 2: The SkyLine and Control Towers are designed for quick and easy removal and reinstallation once initially installed (the Landing Pads remain on the vehicle). Removing them when not carrying anything can be useful to decrease noise and energy consumption (particularly with RoundBar crossbars). Obviously, this makes it easy for thieves, so locks are essential with this setup.
