Hi, BBS LM 285, 9x18, 50-mm offset with 225/40-18 Pirelli P-Zero Asymmetrico N4 tires fit beautifully at the front end, with no fender modifications.
BBS LM 277, 11x18, 56-mm offset with 285/30-18 Pirelli P-Zero Asymmetrico N4 tires barely fit at the back. Some minor fender rolling was needed at both rear fender lips. I used a duct-taped-wrapped aluminum jack handle, my wife's hair dryer--and lots of patience--massaging the fender lips upward just enough for the needed clearance. There is very slight rubbing on the inboard side of the tires against the body under full suspension compression when driving through a dip in the road (probably due to the 1.5-degrees negative camber at the rear)--but it's not terrible. There's also a touch of tire contact with the body when going up a steep grade driveway at an angle--more of an annoyance then anything destructive.
The black aluminum closed-end lug nuts were ordered from Pelican Parts. BBS sent open-ended black aluminum lugs with the my order, along with brand new valve stems. I opted to use plain black Slime brand TPMS valve stem caps from Auto Zone, and kept the BBS valve stem caps, as the plain black caps look better with the black/gold BBS center caps, and black lug nuts.
My 1995 993 Carrera has the factory M030 sport suspension: ~4.8 inches ride height front, ~4.5 inches ride height rear--it's high enough to run my car through an automated car wash (Crew/Mike's here in the Indiana/Ohio area) during the winter months.
These wheels are brand new current production BBS LMs and purchased directly from BBS USA (Robert Way). BBS stocks the LM 277 11x18s, while the LM 285 9x18s were special-ordered from BBS Japan with a 3-month wait. The results are well-worth it.
Bill was clearly right about 11”ET56 not fitting in the rear. That doesn’t look right at all. I’d also question whether ANY 11” wheel makes sense, not just because of clearance but also because you end up with very little tire sidewall to protect the rims.
It’s been long known that 10”ET56 is pretty much the limit, so another half inch(11”ET56) can’t be expected to work.

Bill has a lot of theoretical data, but theory doesn't match actual results of a set up.
If you don't want to fool with massaging fender lips, go with a more conservative set up.
I absolutely love the BBS LM 277 11-wides with 285/30-18s; the set up takes the car's aesthetics to a whole nuther level.
The narrow body rear fenders add to the car's tight stance.
The 11-wide LM 277s are the only way to get the deep rim lips, otherwise you end up with factory stock 10-wides with shallow rim lips, and what's the point of that?
Every time I park my car, I have to look back and marvel at those steam rollers stuffed under those narrow rear fenders.
I have a set of Fikse FM-10s sitting idle now. They were 8.5/10-wide; 225-40/265-35 x 18s--they pale in comparison to my brand new BBS LM 285s/277s.
Finally got the chance to shoot better photos in a parking garage.

FWIW, I no longer experience any rubbing in the rear. I've put 1300 miles on the rear tires, and the tread depth must have worn down just enough to provide the needed clearance from any body work.
BBS LM 285, 9 x 18, 50-mm offset with 225/40-18 P-Zeros (fronts) and LM 277, 11 x 18, 56-mm offset with 285/30-18 P-Zeros (rears) are now matched with a new Bilstein PSS10 suspension.
The monoball spherical shock mounts and camber plates were re-used from the previous custom coil-over suspension which now has surface-rust forming on the front Hyperco 2.5-inch outer-diameter racing linear-rate coil springs, and the rear 993 Turbo/RS shocks are leaking.
Bilstein PSS10s were sourced from Madviking Performance, Louisville, KY at $2985.29 including Indiana sales tax and shipping.
PSS10s were installed at Autobahn Service Center, Greenwood, IN. PSS10 installation labor, $900. 4-wheel alignment to Carrera RS spec was $250.
With PSS10 adjusters dialed at setting "5" ("1" softest, "10" hardest), ride quality is improved relative to the old Carrera RS/M030 suspension with Hyperco racing coil springs.
The M030 front shock setup and rear Hyperco 2.5-inch outer-diameter racing coil springs are salvageable. The Rear 993 Turbo/RS shocks are leaking, and will be tossed. Make me an offer, if you have a use for the salvaged suspension parts.
Camber (L/R), -1/-1 front, -1.3/-1.2 rear.
Front Caster is (L/R) 4.5/4.6 degrees.
Toe is 0.05 degrees front, 0.47 degrees rear.
Thrust Angle is -0.01 degrees.
Ride height is 4.5 inches rear (from rear subframe to level ground) and 5 inches front (from hex bolt at front crossmember to level ground).
For reference, Carrera RS ride height is 4.2 inches rear, and 4.9 inches front. ROW is 5 inches rear, 5.7 inches front. US-Spec is 6.2 inches rear, 6.9 inches front. (See Adrian Streather's Porsche 993 The Essential Companion published 2005-2008).
Sorry for the necro, but @Domer911 — what wheel sizes (width, offset) and tire sizes are you running here? Springs/coilovers? Fitment looks good and the 15mm spacer on the rear clearly helps fill the guards.
