Welding the diff

I heard from a friend the other day you can take the car to a shop and they'll weld the open diff to completley lock it up. Is this real, safe, and cheap? i'm tired of one wheel tire friarer burn outs.

It's great if you only plan on going straight. When you make turns the rear needs to allow the tires to turn at different speeds. The outside wheel has more ground to cover. If the spider gear is welded 'closed' the tires will spin at the same speed all the time. If you are turning left into a driveway the left rear tire will be spinning(breaking traction) putting undo stress on the axel and diff causing it to fail prematurely.

Upgrading the diff is a much better choice, it's expensive for a reason. Upgrading to an 8.8 is the best option by far, especially if you plan on adding more HP or forced induction.

I guess, don't really know that much about drifting. I do know no matter how you intend on using it once it's welded it will not last long at all. IMO any shop worth using will advise against doing it, and if they will do it they won't stand behind it. Simply stated, it's not a good idea IMO.

If you get a good LSD the the effect would be the same when one tire spins both will lock up. Or you could seen about getting and elocker like in jeeps. Idk if anyone makes one for your car but it's a free diff unroll you press the button then it's a full lock. Then press the bottom again to turn it off.

never ever do that unless you only drive it at the track (drag strip)
