4 lug or 5 lug?
If it's 4 lug, I doubt you can use much spacer at all...those stupid lug bolts are a royal PITA.

How about something like on this site? Would this be a good ideal?
They have 108x4 to 108x4 adapters, you would not have to change out rims.
I am thinking about this for the back because the rear tires look too far in from the fenders.

Also this site, 69.95 pair (us $) http://www.ezaccessory.com

It's a 4 lug. Do you know the thread lenght of the standard wheel bolts?

Those adapters are only for use with cars using wheel nuts.
or not?

That depends on which wheels you have. I'm pretty sure the spiderweb / basketweave wheels require ~70mm lug bolts. The stock 8 spoke rims require shorter ones, but I can't recall what the size is...maybe ~50mm or something like that...

PET says the lug bolts sizes are 14x70 and 14x25.

I have researched these adapters, some ask if you are using wheel bolts or lug nuts,
and they have a wheel bolt kit, which I am assuming are the correct bolt length.
Measuring from outside wall of tire to underside of rear fender, 1.25 inches would be real close.
I did consider spacers, but is 10mm going to make much of a difference?
I'm just wondering, because I want to do something for the rear stance.
I found these people locally, I will be talking to them to see what they suggest.

I'm using wheel bolts. Yes, maybe I made a mistake with the meaning of the words. Definitely, wheel bolts.
I haven't measured the distance between the tire and the rear fender in my car. You say 1.25 in (near 32mm). But I suppose it depends on the width of the tire. I'm using a 205mm width. I don't want to keep it so close to the fender that the wheel brush past the fender.
Yes, maybe 10mm is too few. But i wouldn't fit more than 20mm spacers.
Anybody knows if the wheel bolts of the ebay link above are appropriate fot the 8 spoke rims?

absolutly not they wont be long enough for safe operation.
4 bolt drum brakes are tricky, if you use too long of a bolt it will lock up the wheel and too short and you run the risk of the wheel falling off.
and when you widen the rear track it will understeer more

The 1979 Sebring M471 option was for four-wheel disc brakes. The wheels
were 6" X 15" with 205/60 H15 tires, usually Pirelli P6s. The option
added $1400 to the price of a 924. The option was offered MY1979 to
MY1982 in the US. My 1981 924 has this option.
The same 5-bolt wheels were made standard for the MY 1981-82 US 924
Turbo, all ROW markets had these wheels as standard. 16" X 6" forged
wheels were optional in all markets with the M471 option, front and rear
swaybars and mandantory four-wheel disc brakes. The standard 924 M471 wheels were the cast spider-web type ATS cast wheels, 5-bolt versions of the 4-bolt normally offered.
The rear wheels also used a 19mm spacer to improve handling, this
induced understeer. The 4-bolt application did not use a spacer, though
the factory offered one and recommended it to improve handling. |
I would like to add ~20mm spacer at some point to my NA because I agree the stock wheels are in too far. However, I probably will switch to 5 lug before I invest any further in the 4-lug setup, but if I were to retain the 4-lug, this is what I would do.

I was talking about the 35mm bolts.
If the 25mm bolts are the right bolts for the standard 8 spoke rims...
Why the 35mm bolts are not the right bolts for the standars 8 spoke rims + 10mm spacer??
I can't even fit a 10mm spacer at the rear???

Not meaning to hijack, but what is the verdict on 1" to 1.25" adapters? It seems these would allow
a wider stance and be more sturdy, or are they? I would like to have 5 lugs, but it's not in the budget right now.
I am thinking, if I do a 5 lug change, I may as well get an old 944 and use it's parts.
