Dear friends,

the LSD in my 993 is out and I am thinking about buying a RS LSD....any advise?

I use to track the car once per month but is not a racing car....HD'S, M030 springs and RS sway bars

thanks

Bill Verburg

I think that you'll be happy w/ that purchase

JULIOFA

thanks Bill....I also heard about Quaife or Carbonetic....any idea?

Quaifes are not recommended for track work, although the lack of decel lock up might not make a difference to you. I have a Quaife in my Miata and find it to be fine for, ahem, brisk street driving.

Bill Verburg

It's hard to beat the factory RS lsd, a Guard would, but it's overkill on a 300hp car.

Quaife might be an option for A/X, I know nothing about Carbonetic

JULIOFA

do you have any opinion about these ones:

While on the topic just curious....If a car didn't come with a LSD is that something that can be added easily at reasonable cost?

Bill Verburg

the 40/65 is the 993RS lsd, the 20/80 seems to be less appropriate but I don't have any real experience w/ them, 964 RS & 964t used 20/100.

For years the normal 911 lsd was 40/40. The street 993 used 22/40 or 25/65 and RS used 40/65. GT sells 40/60 or 50/80 the latter is more of a track only unit.

The xx/xx numbers don't tell the full story either, preload and # & make up of the disks changes the feel.

For most dual purpose cars most of the time the 40/65 is a great compromise

Bill Verburg

reasonable is in the mind of the beholder, it could easily cost ~$3k

Mark in Baltimore

It's very possible but not likely, depending, of course, as Bill mentions, on your definition of reasonable. I bought a new Guards LSD for $1700, IIRC, and spent another $380 to install it. I think it was a very good deal.

Bill Verburg

It was!

JULIOFA

thanks a lot for your help. I will check Porsche original RS lsd and, if too expensive, I will go for FVD one
thanks again

I have a new RS CS LSD listed for sale in the classifieds (it is from a G50/32 transmission). New from Porsche it's $1995 according to my dealer, I'm selling it for $1500.

A new Guard unit is about $2400.

JULIOFA

thanks Tom. I will check prices and let you know. Do you know if is suitable for my 993s?
thanks
