86 944 trailing arms on a Ghia

[wrenchnride247]

The '88 ali arms are the same on both turbo and non-turbo. The ali's have different bearings than the early steel arm's. You might have a problem with stubs, rotors, and e-brake shoes fitting. The late ali arms are wider in the casting not the hub. So you will add track no matter what stub's you try and use (the late ali's add the most track ) .

the steel armed hubs from a 924s/944 fit bug axles -they have bug splines
-i just tried a bug axle in both a 1985 and a 87 turbo hub -alloy arms
-and they dont fit
alloy hubs are fine splined -steel armed are fluted splines, -the same as bug

the steel arm 944's use the exact same arm as a bug -the hubs are the same -drilled differently 'for arguments sake'
-they then as described above, have a 22mm factory spacer fitted
-they say the track -with this spacer is the same as an early 944 alloy 1985 arm and disc /hub

-so realistically, an alloy arm is 22mm wider than a steel arm
-the leter 87 onwards 944 have a wider hub - widerdisc -extra 25mm per side

-so if as matt says, you simply remove the stock spacer of the 944 steel arms -the track is the same -use bay window studs
-ps a brembo will catch a fuch -you NEED 7mm spacer -at least

Hi Paul, I assumed the hubs were the same, they look it Like I said the hubnut's are still on my Ali arms, on the shelf for nearly 4 years.. I would have them on the car if Day Moulding wings weren't so damn fine.

I'm currently closer to stock hieght with 23.5mm TB's and -1deg camber with a 215/45. Preparing for T4 power soon 'Drives fantastic!

T25 wheel studs are available new from VW not dear.

-here you can see with the rear disc spec the difference in the 85/6 only discs and the later typpppppppppe

-late 944 disc 100mm
-85/6 alloy arm - 70mm

-30mm increas in track
-86 arm is same as steel arm with 22mm spacer

-so 87 alloy arm = 52mm wider track than bug
-86 if its the same as steel with 22
-simply increases the track 22mm
?

-also note steel arm disc is 289 by20mm

-where as 86 alloy arm is 299 by 24mm -4 pot brembo

-also worth noting that the late 911 uses the same disc? -299 by 24 -but as standard is drilled?

now i think i have answered my own question
-i have the adaptors that take these arms to monblock bremboo's
-now i reckon i will need boxter 's' calipers rather than the smaller boxter ones, as they seem 289 by 20
ho hum -does it mean i can do either tho?
-ie if i get the small engine boxter calipers -fit the 289 20
-if i get boxter or 996 - get the drilled 911/964/

-coolio
anyone have any calipers for me?

also i'm not sure what the back spacing is on c2's but if it's more than 6" it'll be a tight fit.

With narrow Al trailing arms, would it be possible to fit the wheels and tires under the Ghia wings? What offset/backspacing would be needed? What Porsche wheels would work? Any pictures?

This is a pretty old thread, but I'm also looking to fit the '86 951 trailing arms under Ghia wings. The trailing arms have the bump stops which as I recall from a Superman thread confirms that they are the narrow arms. What size wheel can I fit, and what offset should I look for (again, under stock Ghia wings).

Thanks a lot.

P.S. Alloy arms are pretty. Is it weird that I what to polish them to a mirror shine and clear coat them like that?
