So if you buy gears from a wrecking yard, do you have to weld them?

Yes, or put a spool in then.  THe junk yard gears should be a posi or an open gear ( one wheel spin ) For racing the gears need to be tied together with a spool or welded..

Now is that an INEX rule?  Cause having the spiders turn freely would make the car turn better.

rule book states

"the rearend must be locked(all spider gears welded or steel spool..). No  limited slip differentials, aftermarket differentials, quick change, floaters, homemade or otherwise are permitted.."

I think that about covers it,

RB,

 If you are running circle track you want to have the rear end locked.
You can use stagger of the rear wheels to aide in cornering.
 If you are running autocross........ I have heard that the open rear end or posi rear end may be helpful.
So far, I am still leaning towards the spooled rear end for my car.

why do you "want" to have the rear end locked.  Going around a circle causes one wheel to turn faster than the other. If it is locked then one will loose grip before the other.

So you have power to both rear wheels, otherwise (especially on dirt) you just have one wheel pushing the car

It mostly has to do with getting the most power to the ground.
When a car is turning, the outside of the car is supporting most of the weight. (Weight Transfer)
This means, in effect, that there is less traction available to the driving wheel on the inside of the car.
Without limited-slip, or in our case, a locked rear end; you soon reach a point where all the power you are applying is being used to spin the inside tire, not to accelerate you down the track.  :o

There are some other things, but that is the most important part.

Does that help  ???

Break an axle and you will know why the rear ends are locked ;). If you break the outside axle the car will burn the inside tire off all the way around the track. If you break the inside axle you will  spin out coming off the corner so fast that you will not know what happened.
