Dumb newb VW guy question on lowering
 
My car was lowered to european spec when i bought it, my question is, was this all done with the original equipment ? how much is the euro spec car lower than U.S. and can the front or rear be lowered any further if it was done by adjusting o.e. parts. Reason I ask is I will be fitting some 16x8.5 and 16x10 wheels next week and not sure on the tire size i will need to get the look I want. I dont like the front gap currently in the front.

Yes. 911's of this era can be lowered and raised with suspension adjustments, no parts needed.

Euro is lower than US, but not low enough in my opinon. This has been debated at length.

It can surely go lower with o.e. parts.

Search and you will find tons of info.(try: torsion bars, indexing torsion bars, suspension, height, euro height, lowering, etc etc)

Your front does look high from this angle-could be the wrong aspect ratio on your tires too. You want to try and stay at the approx 25" diameter no matter what diameter wheels.

Just research the subject as Jim advised. The front is a lot easier to make larger change on than the rear. Also note that when you change height, you should re-align. And then, there is corner balancing too. Then, if you go too low, spindles need to be raised (not a DIY project) to keep the geometry withing its design parameters. Shocks may need to be tweaked as well, as they'll be working in a different zone. But, within moderation, you should be good with just working the T-bars and the re-alignment.

If you're handy, you can do it all at home, and it is a good learning experience on your suspensions nuances. CB requires scales, so that one may be a little tougher to pull off at home.

Dump it.
It's been a long time since I had a Cal Bug but if I remember correctly you pulled shims out of the front and twisted something in the rear.

Anyways it's the same theory with a Porsche. Turn screws in the front and twist in the rear.

This is 23 3/4" X 24 1/4" on 16"s.
Well below euro.

Make sure your front end is lower than the back. These cars need to be raked for stability or they will try to take off.

Accordingly, a higher measurement to the front lip, can still be a downward rake. For example, Ed Hughes' targa is/were 24 1/4 front, 23 3/4 rear. This 1/2 inch "higher" in the front is still a downward tilt of the car, as you are measuring the fender lips, nothing more.
