Not a good idea for a street car, barks the tires and is a bitch to turn esp on low psi slicks. Plus it can get a little intersting if you brake a axle the car likes to violently turn. Im going to a LSD after running that dif for a while.

Essentially prevents it. The whole point of a front diff is to allow the wheels to spin at different rates when turning. The spooled diff obviously does away with that.

I would not want to be driving any car on the street with a welded diff...but thats just me.
I like turning, and infact I think it's one of the top reasons why I own a honda.

No, it's not worth it, unless it is a drag setup, as someone mentioned. Spooled differentials promote massive understeer, especially on FWD cars.

then why are there so many people out there auto-xing on welded diffs then?
granted, its because they cant afford a LSD, but if it were so bad, wouldnt they just stay open diff??

While I've never seen a spooled FWD auto-x rig, it is possible to tune the suspension to limit the understeer. Maybe a swaybar tune to limit scrub loss on the inside tire, maybe a tight rear setup to promote better turn-in and mid-balance, maybe they just don't know what to notice...
All I know is that spooled differentials promote understeer. Fact. Why you would want to promote that in a FWD, understeer-prone car is beyond me (again, with exception to drag cars, but that's a whole different bag of tricks).

You cant turn with the diff welded, Both Tires will be spinning when you turn, it will be hard, and make lots of noises..
Welded diffs are for DRAG cars, not a stock car like you probably have

it's pointless, and ignorant
it's allready bad enough having a LOCKER in the front diff...but a spool/lincoln locker would be hell......steering becomes VERY difficult, especially 90* or U-turns....as it will push the car out (understeer) and it will be VERY hard on your drivetrain.

what??? never seen anyone that ran a welded diff autox'n a FWD. wow i can't imagine how unbearable that would be to autox, let alone SLOW

Exactly what I was thinking. No way in hell I would run one.

wow. there are multiple street FWDs welded here. and a few auto-x cars. 3 of which are always in the top 10 for fastest time of the day. my welded diff car turned well under acceleration, the inner tire spinning faster seemed to pull the car deeper into the corner.(ONLY WHILE ON THE THROTTLE)

It was an illusion. Your savior was most likely a lack of normal force on the inside tire, removing/negating scrub losses generated.
