Subject: Re: RotoFlex Suspension
I don't know about the GT6+, but this divice is standard on BMW's. My BMW
6er (a large, 4000lb touring coupe, as well as a high performance car)
uses one of these between the trans output and the drive shaft. They have
about a 75K life expectancy and cost about $40. However, they are PITA to
replace, since you need to drop the drive shaft to replace them!
Cheers
