also posting this on the wheels board so sorry if you see more than one post.

ok.. ive got my eye on a set of 7J x 15 H2 ET23, 5 lug, Bolt pattern 5 over 130mm with 23mm offset BBS (old school basket weave style) wheels for my 68 912.

are 7's too wide? has any one tried these (or any 7X15 wheel) on an early (1st generation) 911 succesfully? (i think its posable on the lwb.. anyone know about swb?)

if so, what did you do to get em to fit right?
also what tire size, model year/how are fenders done, (and if you didnt use bbs wheels what brand model/specifications etc were they? IS ROLLING OR CUTTING FENDERS NECESSARY??
would there be a way to get them to fit with out problems, with out resorting to rolling or cutting fenders? i have original fenders on my 68, dont really wanna cut, roll, or flare.

also would 205/50/15 be the correct tire size for those wheels on a 68 912 (or 911)?

sugestions, tips, etc are greatly appreciated.
thanx in advance guys

Bruce Anderson talks about wheel fitment in early 911's in the current issue of Excellence. I don't have it handy, but I believe it has a GT3 on the cover.

Harry, I have 7x15 Fuchs on the back of our 73E and there's some sidewall rubbing against the fender lip under heavy cornering (right side only). It's improved since I increased the rear camber from -0.5° to -1.0°. I think another -0.5° should do it. Of course this will impact tire wear.

Hmmm, a short wheel base car, before the "flares" of '69? Negative camber, some fender rolling, stiffer torsion & sway bars...maybe! Being conservative, I'd suggest going with 6X15 fuchs instead...I'm running 7's on my '72, and did all of the above...but only factory suggested negative camber, can't recall the number right now.

Bill,
is that issue of excellence the one with the article about the boxster vs the z4? or is it the one thats due this month thats not in stores yet?

the 6x15 fuchs are my fall back plan. since i am really trying to avoid the fender rolling, what can you suggest as far as torsion bars and how can i find out the suggested camber?

currently i have a very pretty set of polished crome 14 inch fuchs. these are good to show, but have no go.
i need to get a set of 15s cause im sick of the tire roll, and need some more performance. i like the bbs style, remind me of the racing wheels of the 70s and early 80s. my car isnt a concours queen, and alrady has turbo mirrors and bumper update kit, so im not concerned about originality (except all my mods can be taken off with in a day and she is back to orig spec)

It's the June issue of Excellence and Bruce answers a readers question about wheels on early 911s. His answer is a little vague though. He states that some wheels will fit on one 911 and will rub on the next! I too would play it safe with 6" and maybe use spacers to bring it out a bit. Another factor is wheel offset, I was able to put 15x7 wheels on my 356!
Good Luck, Robert

robert,

how did you put 7x15s on a 356?

any suggestions on the 6x15 fuchs? i understand there are 2 or 3 different fuch designations for the 6x15s. which ones will fit best? do spacers do anything than help them fit correctly?

im basically making mein 912, into my own. its super solid, amazing condition. not quite a show car quality tho. b/c of its condition, all of the mods i have made are stuff that can be easily changed in a day back to original(ie update bumper kit, turbo mirrors). thats why i dont wanna roll the fenders, or even risk it -too nice to go nuts on. its an outlaw, but nothing over-kill (which most 912 owners do when the decide to outlaw). i like the car to be subtle and let what it can do, do most of the speaking, so im gong towards performance upgrades... hense the bbs's and not fuchs.. reminsicent of the racers of the 70s and early 80s. the engine is already 1750cc big bore.

im going to have to wait til my nearest barnes and nobles gets the nex excellence in.. stopped by twice this week looking for it. got the new GT Purely Porsche.. god damn not only are the articles in their mag great, their photography is amazing!! compairing the new carrera gt, to past porsche super cars... great article

HArry, deep sixes (Wheels made until late '71) and the flat sixes (Wheels made from '72 up) both have the same offset, so clearances issues would be the same. The only real difference dimentionally is in the design of the spokes. Deeps are considered more attractive by some, usually sell for a bit more. But deeps were designed for tube type tires, you'd need a special valve stem to run them with tubeless. How stiff? My '72S is probably a bit too stiff for the street, but since the conversion was done back in '76, I've kept it. 23-28 on the torsion bars, 19mm sway bars front & rear. You might want to lighten this up for a 912. I have no idea whether a short wheelbase car would have clearance issues with even the 6, since the first 911S ran 4.5" wide fuchs...

Harry.....
A 356 Custom shop in So.Cal. cut 15x5 in half and added 2". All offset was on the inside. With half inch spacers they fit perfect! I've had these on the car for ten years and have had no problems, high speed, balanced perfect, etc.
Cheers, Robert

pwd72s,

well, alot of 12ers i know run 6x15's. even the swb guys, so i dont think clearence is a big prob.

so are the later flat sixes the ones with the 'j' designation? (ie 6Jx15)

pwd72s

I'm not sure about the early "deep" sixes. But the original "flat" 6x15 I still carry as a spare has "6JX15" stamped inside one of it's spokes on the back side, followed by the fuchs "foxhead" trademark. There is also a circular "seal" in another spoke, looks like it was stamped in either paint or indelible ink of some kind, not stamped in like the foxhead and "6JX15". Hope this helps. Now, back to the garage to put my trunk area back together... <img border="0" title="" alt="[Wink]" src="wink.gif" />
