Why ,This is why:


- Requires a different way of taking corners. Must accelerate through a turn, to the limit of adhesion, taking care not to break the tires loose and cause oversteer.


- Tires make noise at very low speeds (typically parking, or U-turns) as the wheels "fight" each other. The wheels are traveling at the same speed, but along different radii, which causes the outside wheel to shake, hop, and break loose at low speeds. This will increase tire wear in normal use, but if you really care about tire wear over performance, you wouldn't be welding a differential. Let it also be known that most 2-way LSD's exhibit this same characteristic, especially the more aggressive ones.
- Car tends to "push" at low speed.
- Not recommended for inexperienced grip driving. Can be very effective and far more consistent than an open differential, but requires advanced driving techniques.
- If the welds break, they can cause differential lock, and lead to a potential accident.
