to expand on the previous post....

If your looking for a road racing and drift car only, go with welded. No doubt about it.

If your looking for a car just to drive on the street, go with VLSD or S15 LSD.

 

I would say more for drift only. Road racing will require an LSD. Some drivers will argue that but I guess its all up to the drivers preference. A welded diff will understeer going in and coming out of a turn. An LSD will give you the slip needed to cut in smoothly with out understeer.

Road race= LSD
Drifting= LSD or Welded diff
Daily= 1.5 way or VLSD

 

eugene: ppl say the same thing about 2 ways under steering on turns. We obviously do not experience this because we get used to the new dynamics of the car and compensate our driving for it. I've driven on welded diffs and they feel just like driving a 2 way to me. I've never road raced on a welded with slicks which obviously make a huge difference but i dont think its going to be so terrible to the point where the driver can't even turn the car. Many grass root road racers run welded BTW. It's an excellent alternative to a 2 way LSD.

but going back to the point of this thread... if you do not intend for your car to be a serious track only race car, don't look into 2 way LSDs or welded diffs. Stick with something OEM and simple.

 

i have heard welded diffs are fine for daily its just loud at low speed turns.

 

You heard wrong. I hate my welded diff, daily. Burns through tires, a bitch to pull into parking spots, pushes on regular turns. Ill be ordering a kaaz or tomei soon..

 

yup, hey dan, you still have your old s-tecs?

 

I was going to use it for daily driving mostly. But I still wanted to be able to do some road racing and drifting on the side.

 

Then youll want a VLSD.

 

I told you so .

 

This is all about traction. If you want to have traction when road racing and street driving, get a limited slip or keep the diff open. If you want to easily break traction for drifting, get it welded or get a 2 way LSD. A welded diff on the street is just asking for a headache and too much tire wear.

If you talk to someone with a LSD that says it understeers as bad as a welded/spooled diff, their LSD is not adjusted properly. There is no arguing that. It's too tight, and it's driving both wheels instead of allowing a speed differential like it should. It's not fair to criticize something that isn't working properly.
