Have u looked at the control arm bolts that are prone to breaking on the older models?

No, could be that. I'll have to ask next time I'm around my (much better mechanically inclined) friends.

However, it souds like the engine/clutch shudder the 1NZ-FE seems to be notorious for in the MT version. Try and bleed the clutch AS WELL AS THE SLAVE CYLINDER and see if that helps. I did this on mine last moth and it worked amazing for about 3-4 weeks and now it back half as bad a before. Only other fix is to just give it more gas until clutch warm up. Does this only happens for the first 10mins or so of driving?

Wheel is fine on the stands. Everything looks perfect and runs perfect in the garage. Its only when actually out and about does the problem happen. I'll look into doing what you suggested. I'm not sure if the problem happens after the car is warmed up honestly, I'll find out friday when I have to drive the thing 1.5 hours back home (thankfully it drives perfectly fine when you get up to speed). You said after bleeding the clutch and the slave cylender that fixed it for you but only for a month?

Yes, I've noticed the problem on cold starts again, although less frequent then it used to be. It may be a design flaw in the slave cylinder since it does go away for about 4 weeks after bleeding it (using both hands to "force" bleed it).

Once the clutch warms up I doesn't shudder even when under really low RPM. When it's cold I have to be sure to rev it higher when going from a stop to avoid excessive shudder. Google clutch shudder in a yaris and you'll find many people with the problem. It seems to go away when a different aftrermarket clutch is installed. As bad as it feels when it happens I bought the car with 87,000km and now have 130,000km on it and absolutely zero sign of lcutch wear so I don't think it is causing any damage.

It may not be that, but I'd look into it if the noise goes away when your clutch warms up.
