Westfield Owners - need some guidance on a LSD

[David Hansen]

I have a Bob Yarwood built seiw from around 1990.

 

I am running out of mechanical projects on this car and I want to install a LSD.

 

I believe my existing pumpkin is out of a Sierra / XR4ti and I wanted to query the room to see if anyone has done this and can give me some direction.

 

While the weather is getting nicer here in the pacific northwest I still have a little time this spring to make this change.

 

Let me know if you have an wisdom to pass along.

 

thanks

I have a Westfield with a Sierra diff and it is fit with a Quaiffe limited slip. I autocross the car seriously and it no doubt makes a considerable difference in my times.

 

That said...if you are not competing in the car...or you rarely, or never, spin up the inside tire coming out of a corner then I think there would be no benefit in fitting the LSD.

 

In the end I think it's about how the car is used. If it's strictly a street car there's much less need for an LSD. The LSD has had no noticeable effect on the driving experience unless you are driving very hard out of corners and having the inside tire light up. The LSD diff doesn't hurt anything in less than race conditions, but it also brings little to the table.

 

I hope that makes sense...I've not finished my morning coffee so who knows how well I'm making the point.

An alternative to Quaife

The thing I want to avoid is the landing shock on the inside wheel, if it were to happen. It's more of a concern for me with my Ital, than for you.

This kind of diff might be, gentler?  

Not sure.  I am sure is more $$$ than quaife.  It may be worth it.

Not many players in this game for my Ital axle, but there should be more options for the Sierra.
