putting wedge risers between the truck base plate and the board will help make a longboard a little more steady at speed while making it a little harder to turn, here's my question...how much is too much to angle a regular skateboar truck (old school or new school axl width) in an effort to make the trucks more steady at speed? has anyone ever experimented with this? fast eddie outty

Over 11-15 degrees negative wedging ie to wedge out steer with the Randal 50 degree baseplate makes the truck unstable and the same goes with any other truck. Also the stress the mount bolts suffer is tremendous for some reason. Ive had every single wedge design made and even custom ally wedges to tweak my downhill and slalom boards and ive settled on 11 degree postive steer front and 11 degree rear negative steer wedge for slalom.
For downhill boards i never went above 10 degrees negative wedging front and rear as something about the geometry of the randal RII makes it twitchier under a wedge. The Randal DH truck never needed a wedge even at fair speeds 35-45 mph.
Oh yeah the one wedge that stood up to the test was the 10 degree Khiro riser with limited deformation under load and it was the only one that stood up to extreme abuse. I think ive got a few of the 10 degree risers hanging around give me a shout if you want them.

How would this apply to Randal RII's on a luge? I, and I suspect many other beginners, cannot afford the luge trucks. I have noticed although they are very nice and "turny", would anyone advise "tweeking" the set-up the same way to avoid the wobs at speed??

I run RII's on my luge and to be honest never had any grief with speed wobbles so i've never wedged them. The best thing anybody can do about wobbles is put the hours in riding and you'll find you're able to control the deck or the luge a lot easier. Its all down to experience really apart from when you need a slight tweek for a specific course then always tweek bushes and tightness before whacking a wedge in there.

Longy, do you know where I can get a 10 degree wedge? Lush don't have them (they have a 12 degree one which I suppose I could sand down, but I'd rather get hold of a 10 if I can).

In the post first thing tomorrow morning chap its the 7 degree riser but probably the one you'll need rather than the 10.

That's really kind, thank you!
The reason I was after a 10 degree wedge is that I was trying to get hold of a 60 degree Randal Luge truck (to match my current ones) but can't find any anywhere. I found a 50 degree one though and therefore wanted a 10 degree wedge to even it up.
Cheers,
Jason.

If you put the 7 degree wedge under and flip the hangar on the RII you get the same negative castor as the luge truck, in fact just the ten degrees you want. The Khiro wont deform under stress which makes it the perfect luge riser, non squidgy.

...but I need it 205mm wide too.

...but I need it 205mm wide too. What? the hanger or the riser? The hanger width doesnt change when you flip it. Turn it upside down and you change the castor angle by 3 degrees or so.

The axle width: On the Luge trucks they're 205mm.

The axle width: On the Luge trucks they're 205mm. If its a comp 2 truck i think you can still flip the hanger but the castor angles im not sure of cos i've never had one. If you wedge it negatively ( i think the comp 2 has a pivot angle of about 60 degrees or so) it'll make it have the same pivot angle as an RII 180 about 50 degrees, more stable in other words. The length of the axle wont change due to dewedging the truck itself.
