Hi.

I have a question for you guys. What is actually the difference in suspension components on those two cars. I have checked on both cars but i cant spot anything that differ.

Sway bars are the same, 14mm rear, and i think 23 at the front. I think its the same size torsion bars. And i did a quick measure on the front springs and it seemes that those are the samte to. Do the have different dampers ?

The options were pretty much the same - perhaps the 931 (later years, anyway) had a more advanced base suspension?

Actually no, as I think about it; while the 81-82 cars had the disc brakes standard, they didn't necessarily have a rear swaybar. My '82 doesn't have a rear bar.

The front springs should be different to accomadate the different weight engines - look for color code stripes painted onto them. The color and number of stripes indicate what they are.
Rear torsion bar is 23.5mm for both 924NA and 931 except for 924NA's that didn't have a factory-installed rear stabilizer bar - those got a 22mm torsion bar. All 931's regardless of whether they had a factory rear stabilizer, got the 23.5mm tb's.

My '82 931 didn't come with a rear stabilizer bar either. I eventually upgraded to 22mm rear and 28mm front as the parts came on sale. (Because, of course, as I've mentioned - I'm a cheap bastard.

)

As far as I know, all Turbos were lowered and had "better" shock absorbers, as well as the above mentioned differences. They also all came with 15-inch wheels (again, as far as I know).

RoW cars, certainly those delivered to Australia, appear to have come "fully loaded". As an example, so far I've been able to gather, all Australian cars came with disc brakes all 'round. It's very likely they all came with optional suspension parts mentioned above.

Porsche are not the only manufacturers to this. Nearly all others do this. For example, when the Audi TT was released in Australia, initially only the quattro turbo was available, even though I think a fwd, non-turbo (and possibly other variations?) was available elsewhere around the world.

Different markets around the world often get different spec. levels of a given model to suit the local market.

Steering ratios also differed depending on year and market. -And brake boosters...
Can't remember where's the link to that tech specs pdf..

Cedric - as you are in Sweden you'll have a Euro car. These had many upgrades compared to the NA cars. But the US 931's only got partial upgrades because the emission regulations restricted the power output (so they didn't need all the brake/suspension upgrades!)

So you will definitely have uprated front springs (I confirmed this by swapping my front springs for aftermarket 924 lowering springs.... but they were way too soft & lowered the car too much as they weren't meant for a turbo - I had to swap back to my original springs!), & the rear anti-roll (sway) bar, discs all round & 15" wheels.

hm, i´ve heard about front springs being different. But the diameter was the same. Must be further investigated. I will swap and take both cars struts apart this winter so i can do the measuring.

All cars here in sweden also seems to be "fully loaded". I have never seen a turbo with drums. And they all seem to have all the unnecessery electric stuff. They also have, what i have seen a little bit more of sound insulation. I found insulation plates that i´ve never seen in my n/a.

Just so you know what i´m doing over here....I´m restoring and making a 931 more track worthy, have the engine totally apart. Lots of work to do.

some pics in this thread: http://www.944sverige.com/forum/viewtopic.php?t=7510&postdays=0&postorder=asc&start=0

I´ll start with a more streety setup. 250# at the front, 25.5mm at the rear. Maybe ill try the 30/19 sway bars. But I´m afraid that i´ll get to much inner weel spinn at corner exit.....

ooop. this had nothing to do with the topic....

Yep - M471 is the 'sport group' option. But 474 is the standard Porsche code for 'sport suspension' (shocks) - so uprated shocks (Koni/Bilstein)should be accompanied by this code.

Trouble is Porsche were a bit inconsistent with codings on each car's build sticker. So you could have had uprated shocks at the factory, but if you also had 'sport group' they might have only put M471 on the build sticker....(instead of both 471 & 474)
