Why don't 993 rear wheels sit in the middle of the arches?
Hunting for a 993 has me looking at *many* pictures. Obviously, the rear and silhouette looks incredible, but one thing throws me off: The rear wheels, when looked at from the side, do not sit in the middle of the wheel arches, but slightly shifted to the front of the car. Why is this and why isn't anyone bothered by this? Please note the picture of the turbo, where this doesn't seem to be the case. I am so confused..

Where the wheel sits in the rear wheel well is the result of KT adjustment
The further forward the less caster ie the less KT.
The less KT or caster the twitchier, faster reacting the rear will be
I *think* the rear suspension is designed to travel rearward in bump. So US full height cars typically have a forward of center wheel and lowered cars are more centered.
E30M3, I am not sure that's super centered, both wheels look a little forward to me.
Bill's is a great case in point, as you obviously know what you're doing and still have them sit forward.
Awesome, thank you guys. I will need to learn what those KT angles mean now. Not a clue

993 has a 5 arm rear suspension, #3 is camber, #4 is KT, #2 is toe, When #4(KT arm) is lengthened, both caster and KT effect decrease, and at the same time raise the height of the rear suspension by straightening the caster angle toward zero, the hub rotates forward and down
Together they articulate around an axis called the instant axis, the dash-dot inclined line seen here
The geometry and nature of the connections, particularly the soft joint at the inner end on #5 determines the camber and toe curves
The arms are in 2 planes, when extended they meet at the longitudinal instant center
