> I was told, that the Torsen never really got into any US deliveries (?)
The Torsens were only used in 89 Turbo S and STX sedans with ABS.
Ratios used are 10x37, 13x45, and 9x35.
(They are pretty touchy in the snow--easy to cut the rear end loose, because
they don't allow any traction-induced slippage, but fabulous on the race
track or for blasting out of a hard turn where the inside wheel would
normally spin a little more.)
