Hmm - for some reason I couldn't see the text in this mail, so I'll try again:

Hello FOT's.

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 8-port 
(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 too!

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?

Best regards
