Rear wheel steering

I posted this under the Chevrolet Silverado but it is worth a post of its own. How to add back wheel steering to any truck or car within Spin Tires. Easy really just open the corresponding xml file. Usually there are a couple of sections at the bottom which look like this:

Mesh="truck/suzukisamurai/LLndtWheel.xml"   
TrackTexture="truck/suzukisamurai/ZidonWheelTrack_d.dds"
Radius="0.54"
Width="0.24"
Mass="300"
Friction="2.0"
Axle="0"
Steer="0.0"
TorqueRatio="2.5"    
ParentBody="cabinBody">

Usually the front wheels will have "Steer="1.0" and the back wheels have "Steer="0.0" like the example above. If you want the back wheels to steer opposite to the front wheels change the Steer value to "-1.0" or if you want to able to move the car like a crab change it to "1.0" For some cars this does look "natural", for example the Chevrolet Silverado and Suzuki Samurai. The Maz-537 not so much but it stil nice to be able to do tight corners with a beast that big 😉

Update 8-4-2013:
Bardaff mentions in his post the following about the value you can change for the rear wheels. Nice bit of extra info!

You'll notice that the value of -1 for rear is quite too big on cars (it's usally more -0,25/-0,35). Yes, it's not only 0/1 value (also useful when having multi steering vehicles like the maz, the second axle turns less than the first!)

    I noticed that modding the big maz, to get rear wheels steering : the farest axles are valued 1 but it decrease toward the centre…

      Adjusting the rear wheel settings does make for some fun driving in the rock parts of some levels. Good tip about the decreasing of value towards the center!

    It appear evident when looking at this http://denisovets.narod.ru/maz/mazprototips/MZKT79221_5.jpg (him again! lol)
    In fact, I tried to mod Dustin's big maz to get closer to this thing (but adding one or two pair of wheels make it glitchy as hell :/
