Thule Evo WingBar vs WingBar

The main difference between the Thule Evo WingBar and Thule WingBar is the design of the rubber strip which sits in the top of the roof bar.
 
Both feature quick access end caps, providing quick and easy loading and unloading of accessories into the 21 mm t-track channel in the top of the roof bar.
 
The Thule Evo WingBars are an updated version of the WingBar, with some improvements and enhancements.
 
Thule Evo WingBars feature a split rubber profile within the top t-track, meaning you can slide a T-bolt into the track without needing to remove the rubber profile.  The split rubber profile means there are in fact two full lengths of rubber in each of the roof bars which separate as the bolt slides along the track.
 
The Thule WingBar design comes with a full length rubber strip which fills the top t-track to prevent wind noise when the track is not in use.  When mounting accessories, such as bike racks or kayak carriers to the roof bars, the carriers slide into the t-track slot on top of the bar, meaning the rubber strip needs to be removed from the bar.  The rubber strip can either be left out of the roof bar while mounting accessories, however this may result in some wind noise being produced from the exposed track.  The alternative is to trim the rubber strip into sections and fill the open track around each of the roof mounted carriers to help reduce the wind noise.
 
Unfortunately, the earlier version of Thule WingBar can not be converted to use the new split rubber profiles as the Evo WingBars have additional grooves along the top edge of the bar to hold these in place.

Similarities between the two types of Thule WingBars -
The shape and profile of Thule WingBar are almost exactly the same.  Both bars measure 80 mm in width and 30 mm in depth.  The shape is very similar to an aeroplane wing which provides the best aerodynamics and reduces wind noise.
 
Will my existing foot pack work with the Evo WingBars?
Yes, both Thule Evo WingBars and WingBars are compatible with the same Thule foot packs.
 
Can I use longer roofbar than the ones Thule recommends?
 
Sometimes it's possible to use slightly longer roof bars, however for safety reasons the roof bars must not extend outside the vehicle's bodywork.
 
A vehicle’s mounting points are always in set position, so it’s important to make sure the feet can be adjusted to the correct distance required for the vehicle.
 

Thule Wing Bars feature a slot on the underside to allow the foot pack to be connected onto the bottom of the bar.  The foot pack can move along the bar, inside the slot, however the slot does not continue through the hole length of the bar, it only extends 25 centimetres in from either end of the roof bar. Therefore the distance between the two feet becomes wider using longer roof bars.

The diagram below shows the slots in the underside of a Thule Evo WingBar and how using a longer roof bar, moves the foot pack position further apart.

Roof bar lengths and model numbers -
The Evo WingBar and WingBar come in five lengths for mounting to all types of vehicles.  These five lengths are the same for both Evo WingBar and WingBar and are shown below along with their Thule model numbers -
