what is the difference between the 911 turbo vs rsr body
 

Who knows? I'm asking about the '73 RSR vs the turbo kits. Are they both 11" rear, 9" front flares? Is it bumpers/extensions that are different on the later "turbo" cars?

Difference is mainly the impact bumpers, RSR was a track car. With the turbo look, you have the "accordian" parts.

If you have the turbo flares, the iroc rsr is simply front and rear bumper. But then you'd have holes in the rockers for the covers that the rsr does not have.

I thought Turbo flares had flat vertical sections on the wheel arches, and the RSR has rounded?

Well, that and the shape of the flares is different. (typed while Craig was typing his reply....)

Yep. Side profile of the openings is different, as well.

This thread has some great pictures of the real deal if you like a 73 RSR

Are we trying to make a concourse rsr? I'm just saying you can make you're 930 look like one pretty easy. Plus my flares I got from restoration design which they themselves bought from Europe are more rounded than hard edged, which I was happy about. The difference is not huge.
Most people use the turbo flare to get the look. When I was looking I didn't see and rsr flares available much less in the metal flare.

Right, sorry I was thinking of the 74 rsr. Those are more like the turbo flare but still not exact. There are difrences between each car.

The '74 RSR flares are nothing like the turbo flares...

JR

True, but only 5% of the population will notice that.

Umm ok dude. I think I mentioned that too. And not nothing. They are similar. Not exact.

These are 9 & 11 turbo flares
Woe is me, my flares are wrong :(

You guys might be confusing the '74 RS and '74 RSR.

JR

'74 RS 3.0 flares are very similar to the 930 but not the '74 RSR's that were much wider.

You know, that was the point I was making...

JR

That IS pretty sweet.

Thank you. :)

I'd been wondering this myself but never bothered to ask. I'd like to eventually swap my (non-original) SC flares for a wider set.

Good info.

Poor bugga. You'll just have to make do. ;)

Here's a pic of how the aftermarket turbo flare from sweden looks.http://forums.pelicanparts.com/uploa...1411054762.jpg
It looks straight but it's not really as it transistions smoothly. Wayner's looks like he's got some fine tuning to his which is awesome.

If you look at the turbo and RSR flares in more detail, the biggest difference isn't the rounded edges on the RSR flare lips vs. the flatter edges on the turbo flare lips. Rather, the shape of the wheel opening is much different. In my opinion, the turbo flares are much more attractive.

On an RSR, the openings are not of a constant radius around the wheel axis. They have different curves in the front of the opening, the portion above the wheel and the rear. The fronts and rears are also completely different, in that the shape of the opening on the front is not the same as the opening on the rear. The front flares aften are not even centered on the wheel axis. If you look at the flares from the front or rear of the car, you'll also see that the flares taper in towards the body at the bottom more agressively. One last major point is that they are blended into the fenders with a smaller radius, when viewed from above. Frankly, a lot of the '73 RSR cars looked like crap. The '74 RS cars look a little nicer.

The turbo flares are more refined. The curves are more consistent from the front half to the back half, with a smoother shape that is more tied to the center of the wheels. The fronts match the rears a great deal better. They are blended into the fenders with much larger radii.

Nothing wrong with turbo flares on a hot rod... You don't get any points for originality, so why not have something that looks a little better?

Right, like this the turbo prototype. Horrible looking openings indeed.
And you're right, most that do the conversion or backdate however you want to call it, don't even think of duplicating the bad lines of the origional rsr openings and why would they? Unless you have one you wouldn't want to duplicate a mistake. Those Flare openings are mistakes that have been rectified with later models and even later racecars.
Not many cars have that look and thats cool with me. If I saw one I would not hate it though as I love Porsche and Porsche history. You take the good with the bad:)

Java and Quattro are right.

To my eye the original RSR flare appears like someone squashed a nice round flare by sitting on top of it.

Quattro is also right though in that the turbo has a sharper edge along the face of the flare. On my car it has been massaged out because I actually hate that lip, and on newer cars especially the Koreans, that face of the flare looks to my eye like someone shaved off the face of a nice soft curve and made it flat.

I can live with the flat face of a turbo flare compared to many of the new cars from other manufacturers. Having said that, I love the softer custom face of my massaged flares in comparison.

I also welded in a 1/4 rod and trimmed back the inner lip. Here it is in progress before the lip smoothing was completely finished
(you can see the front edge taking shape in the top right of the picture).

Agreed that the '74 RS/RSR flares look like a mistake. 930 flares are a massive improvement IMHO.

Good comparison of the changes between 73 and 74 and the differences between RS and RSR in this thread
