No, Porsche Tequipment also includes suspension and performance upgrades. See European Car Magazines project 996. They used nothing but Tequipment.
There is not etched in stone document saying that BMW is coming out with its own line of performance parts but I believe the writing is on the wall. As most of you know BMW is cutting some of its ties with performance parts maker DINAN and has already denied DINAN the right to produce BMW backed software upgrades. This comes on the heels of rumors that BMW will be producing software performance packages for the 335i.
Honestly, I think its about time that BMW got on the performance parts band wagon as there is a lot of money to be made in aftermarket tuning. I think the best evidence for this move is simply the fact that it just makes sense.
