Steve, Chris, et Listers,
Not sure how much, if any of this post is "tongue-in-cheek", but Rick
McCleod sells the same part number for both Alpine S-IV &V and Tiger and I
personally have never heard of any different specifications between Tigers
and Alpines in this regard. It is true, however, that Tiger lower ball
joints have a habit of breaking, "exploding" if you will, when backing up
because of (I believe) the bad Ackerman geometry peculiar to the Tiger. At
full lock, the Tiger front wheels toe in about 3"!! This puts quite a lot
of stress on the suspension parts and causes the squealing you hear when
navigating tight corners on a smooth surface. Aparently, the stresses are
even greater when backing up, because this seems to be when they usually break.
With regard to Chris's question about the "longer" MGB steering arms, I use
them and recommend them highly, having mentioned them several times
previously on the List. They work primarily because they are angled out
instead of straight ahead like the stock Tiger arms. Being longer (ca.
0.5") helps a little too. Moving the rack back 0.5" helps a little bit
more. Having done all these things, I can tell you that the squealing in
turns has gone away and my cars rolls freely in tight turns, even going
backwards. I use a quick ratio rack, but still have a standard diameter
steering wheel. I believe a Midget rack is a quicker ratio than the stock
Tiger rack and is also better built and generally steers easier, so perhaps
this compensates for the quicker ratio in terms of steering effort. I
personally favor a quicker ratio because it keeps you from having to cross
your arms when doing fast, tight maneuvering; e.g., when autocrossing. Ever
watch those in-car movies of the Tiger rallye car and notice all the wild
arm movements of the driver? Bet he would have loved a quicker ration rack.
TTFN,
Bob
