Wheels look great. My 993 is getting painted to celebrate its liberation as my track car and I've been thinking what wheels I'd like to put on it when it comes back. LM highest on the list!
My 1995 993 has the factory M030 sport suspension with ~4.8 inches ride height front/~4.5 inches rear.
The LMs are 285, 9x18, 50-mm offset for the fronts; and 277, 11x18, 56-mm offset for the rears.
I posted my photos directly in this thread, to show off the difference between BBS's factory stock setup of 8.5 and 10 x 18s on YOUR car vs. BBS's aggressive "Tuner" fitment of 9 and 11 x 18s on MY car.
BBS "Tuner" fitment for 1995 Porsche 993 "C2", LM 285 fronts/LM 277 rears. Tires are 225/40- and 285/30-18 Pirelli P-Zero Rosso Asymmetrico N4s.
No modifications were needed for the LM 285 9x18, 50-mm offset wheels, with 225/40-18 front tires. (The LM 285s are special-order items from BBS Japan, and delivery time is ~3 months from the time you place your order).
For the LM 277 11x18, 56-mm offset wheels, with 285/30-18 rear tires, the rear fender lips needed some gentle massaging to roll them upward to provide the needed clearance. (The LM 277s are normal-stock items at BBS USA).
I used a duct-taped-wrapped Craftsman aluminum jack handle, a blow dryer (to heat up the paint to at least 140 degrees F), and some gentle rolling between the tire sidewall and fender lip
(The car needed to be jacked up slightly to make room for the jack handle to fit between the fender lip and tire sidewall).
Patience is required--if you rush it, you'll chip the paint (I did not thankfully).
I did NOT need to buy a fancy fender roller, as I didn't need that much massaging to provide the needed fender lip clearance.
After 1300 miles worn down from the rears (now 7/32nds from 9/32nds brand new tread depth)--there currently is no rubbing at the rear; the front set is brand new (9/32nds tread depth), and absolutely no rubbing, full steering wheel lock-to-lock.
(The rear axle LM 277s were on the car 3-months before the front axle LM 285s arrived--during that time I had my old 8.5x18, 45-mm offset Fikse FM-10s with 225/40-18 Michelin Pilot SSes up front, until my LM 285s arrived).
I think most will agree--that if one is willing to do pay the extra money for the 0.5 to 1-inch wider widths, and do the extra work to massage the rear fender lips, the results are absolutely worth it!
Your set up looks FANTASTIC Sleep!! I love the deeper dish look vs. mine, much more aggressive.
Ha ha, thanks, man!
The aggressive "BBS Tuner" set up is NOT for the faint-of-heart, NOR will this be a choice for the 993 owner who does NOT want to modify the car to get wheels-and-tires to fit.
Glad to see another fellow midwestern 993 rolling on BBS LMs.
I've had FM-10s for a long time, and the LMs are just way better-looking, and much sturdier (the FM-10s were too fragile for daily road use).
Even my wife--who is not a car person--thinks the LMs in this aggressive config--are an eye-popper.
Photos don't do this justice; you have to see those huge steam rollers tucked underneath those narrow rear fenders--IN PERSON--to appreciate just how tight this car looks now.
The 9-wide fronts are absolutely nececssary, since 8 or 8.5s look much too narrow in relation to the huge 11s out back.
And yes the deep-dish rims look so right on our cars; and the only way to get the deep rim lips, is to go with BBS's aggressive "Tuner" fitment (LM 285s/LM 277s).
Have a great Christmas, and thanks again for the compliment.
Remember--your car looks great as well--just a tad more conservative than mine--but we're both rolling on sweet BBS LMs, bro!
Now you have me wondering if reverse mounting 8.5/et56 & 10/et65 would work on a NB.
Calculated front space for BBS "Tuner Fitment" for the "993 C2" +50-mm offset 9x18 LM 285 with 225/40-18s is ~3 inches (using 10-inches wide overall width).
Calculated front space for BBS "Tuner Fitment" +56-mm offset 11x18 LM 277 with 285/30-18s is ~3.8 inches (12-inches wide overall width).
You can estimate what the new front spaces will be after reverse-mounting your BBS LM 265s/266s.
For the LM 265, +56 offset, 8.5x18, reverse-mounting can lower the offset as much as 15 mm, so your new offset is ~41 mm.
Assuming overall width of 9.5-inches/2 = 4.75 inches - 1.61 inches offset (41-mm) = 3.14 inches new front space (~3 inches for LM 285 BBS Tuner Fitment).
For the LM 266, +65 offset, 10x18, reverse-mounting can lower the offset as much as 15 mm, so your new offset is ~50 mm.
Assuming overall width of 11-inches/2 = 5.5 inches - 1.97 inches offset (50-mm) = 3.53 inches new front space (<3.8 inches for LM 277 BBS Tuner Fitment).
Assuming you have NOT lowered your car to RS ride height (mine only has M030 Sport Suspension), AND your tire sizes/brand/model are the same as mine--you should be good-to-go in achieving the deep-rim-lip aesthetic without going to the 1-inch wider BBS LM 285/277 Tuner Fitment setup.
265/35-18 will likely be the tire size you have on a 10-wide, as 285/30-18 is a little too compressed on a 10-wide, and really needs at least a 10.5 wide to take full advantage of the 285-mm tire width.
11-wides are the best, and only the Pirelli P-Zero Asymmetrico Rosso N4 allows an 11-wide max width for their 285/30-18 tire size; other brands limit the wheel width to 10.5 wide for 285/30-18.
Some cautions to reverse-mounting LM265/266.
Your scrub radius will change when you lower the offset at the front axle (from 56-mm for 8.5 wide, or from 50-to-51 mm for 8-wide)--you will notice increased steering effort; this might not be a big deal, but this scrub radius change might cause undue stress on the 993's power steering rack.
Robert Way, of BBS USA, has never encouraged reverse-mounting BBS LMs; apparently the mating interfaces aren't exactly right when you reverse-mount, and the wheel bolts end up taking a lot of the stress, instead of the wheel center-to-wheel barrel mating-interface.
Calculated front space for BBS "Tuner Fitment" for the "993 C2" +50-mm offset 9x18 LM 285 with 225/40-18s is ~3 inches (using 10-inches wide overall width).
Calculated front space for BBS "Tuner Fitment" +56-mm offset 11x18 LM 277 with 285/30-18s is ~3.8 inches (12-inches wide overall width).
You can estimate what the new front spaces will be after reverse-mounting your BBS LM 265s/266s.
For the LM 265, +56 offset, 8.5x18, reverse-mounting can lower the offset as much as 15 mm, so your new offset is ~41 mm.

SleepRM3, Thanks for the calculations! I heard that BBS doesn't recommend reverse mount, but a handful of RL members seem
to be running it that way with no problems. The center face is recessed where the bolt head sits. I can see that being a issue
when you reverse mount. Most likely the extra stress your talking about. I'll probably leave them alone. Looking at your deep
dished LMs makes me a bit jealous.
