I've seen some people who know a great deal about cars (particularly Bob
Yarwood) who have had some success with them, but I've also seen cars where
they made no useful difference. At a recent race here, a friend named Tom
Morgan had just had one installed and couldn't see a difference. Bob jacked
his car up and turned a rear wheel easily while Tom held the other. If there
was a pound of force being exerted by the Phantom grip, I didn't see it.
They look ridiculous to me.

Subject: Phantom Grip - does it work?
Hmm - for some reason I couldn't see the text in this mail, so I'll try
I am racing a Spitfire 4 in the Danish Championship for historic racecars
and in the Danish hillclimb championship. It's not a full racecar - in fact
it is only mildly tuned, as it develops less than 80 hp even with the
factory "Stage 2"-tuning set - most importantly this consists of a rare
(iron) head and double Webers. The car has been ultrareliable though, and
thats why I ended up 3rd overall in the championship and as
winner of my division in 2004 - my first full season. And great fun it was
Anyway, until now I have raced the car with an 4,55 open differential, but
this is now due for a rebuild. As the car even with its lowly power
suffers from wheelspin from the inner wheel out of corners I am considering
to strech my budget to a limited slip diff. However I have been
quoted up till 1400# (approx. 2500$) for a Salisbury-type LSD, and that is
frankly more than I am prepared to put into my weekend-racer.
I then stumbled across the Phantom Grip (www.phantomgrip.com) limited slip,
which sells for 300$ in the US and about 180# in the UK. I've
searched the internet for reviews, and found them very mixed. Some praise
the Phantom Grip no end, particularly the price compared to "real"
gear LSD's, other acknowlegde the low price but reckons the gains are lower
- some even lower than the price. And finally there seems to be
some questions regarding wear from the sliding steelplates and the resultant
steel debris contaminating the diff.
My question is: Does anyone here have firsthand experience with the Phantom
Grip? And of course - does it work?
