RUF CTR Tail

I was looking at pics of the Yellow Bird and noticed that it has a Turbo Tail with the Carrera Rubber. Or, at least it looks like it does. Is that how they did it?

I am not a fan of the Turbo Tail on a narrow body. It just looks kind of big without the Turbo Rear Flare but this combo is pretty sweet.

Anyone know more about that?

That car, BTW, is not Yellowbird - which was the name given (by the journos) to the CTR prototype at the magazine shootout where it drubbed everything in sight - including the 959...

Note the later-style slotted rear bumpers and the lack of NACAR ducts (only on the original)? Seem to recall Yellowbird didn't have rain gutters either.

Probably. I posted pictures of a 3.2 lip on top of a turbo lip; most of the bolt holes line up. 3.2 has a couple extra/some bolts in different places.

Firstly, the 3.2 lip and the turbo lip are EXACTLY the same width. Everyone seems to think the turbo lip is wider - but it really isn't. Easy to see when one is plopped on top of the other. (I've toyed with fitting a 3.2 lip to my turbo base - but I don't think I'll bother.)

Also, strictly speaking, neither SC nor 3.2s are "narrow body" (which would be a '77 or earlier non-flared car). SC/3.2s use SC/3.2 flares. Also used on the early Carreras, after the factory ran out of RS flares after the first 230, 240 cars.

The CTR, BTW, doesn't use SC/3.2 flares. Or rockers. Because if it did, you couldn't squeeze 10J Rufs under the rear (trust me, I've tried - they don't come close to clearing even without tires). CTR flares are an inch wider than SC flares.

Oh, and the aero drag on the 930 body makes it slower. So neener, neener, neener

True. But as we get older and put on a few extra pounds, we appreciate bigger rear ends!

that car has a turbo tail with carrera lip. it is not an original CTR. I believe it is a 77 carrera that has been converted to look like a CTR. It is supposed to have a BTR engine. Also, supposed to have many original CTR parts, like bodyparts, brakes and suspension. I know the guy who was trying to sell it about 10 years ago. He is from Luxembourg.

No, the CTR did not come with the turbo base and Carrera rubber.



You can see a few more here:

Thanx for the info Ernest.

I always liked that car from Luxembourg. It really is cool looking.

We need more pictures of it.

CTR is 17x8J front, 17x10J rear.

Just FYI Ruf sizes for SC/3.2 are 8J front, 9J rear and 930 are 9J front, 10J rear.

Yeah, I've got 8's in the front, but with a slant nose it fits a little nicer. I'm going to look into a larger spacer on the front wheels, though...

However, below is a link to Flicker to see the photos that I have. I might have more, but can not find them.

Great pics!


For Amir, take a look at this post and maybe you can answer my question?

And as mentioned here, forget about trying to fit 10s in the back of an SC/Carrera. To understand those 10s, you have to take into account that the offset on those wheels is just 5mm. That isn't very much. Hence, when using them in the back of a 930, the spacers should be reduced to 15mm. Others have tried different size spacers but that's the Ruf recommended size. And that's still a close fit. So, on an SC or Carrera, the 10s would require some serious bodywork. Yeah, I tried too. But gave up since I liked the body on my SC unmolested. Here are the 10s with 15mm spacers on my 930. It's a spot on fit.

This is right off some old Ruf paperwork regarding their wheels including spacer and tire size. The interesting thing regarding the turbo sizes is that those are the exact same tire size as used in the 959.


Ruf Wheels
Carrera 8 x 17 9 x 17 215/45 ZR 17 235/40 ZR 17 silver painted, matt anodized

Turbo 9 x 17 10 x 17 235/40 ZR 17 255/40 ZR 17 silver painted, matt anodized
Turbo-Look
15 mm spacers

CTR 8 x 17 10 x 17 215/45 ZR 17 255/40 ZR 17 silver painted, matt anodized

These are the offsets.
Offset: 8 x 17: 30,4 mm, 9 x 17: 17,7 mm, 10 x 17: 5 mm

I run the factory spacers 28mm with my 10's with 275/40's and it fits in there. Guess I got lucky!

I run the 9 x 17 10 x 17 235/40 ZR 17 255/40 ZR 17. I don't know what spacers but it is a RUF set up. I find that the fronts are a little snug and rub in a tight turn, like a square corner or a U-Turn. I have thought about reducing to 225s on the front. I would agree that the 8s are probably a better fit on the front of a Slant Nose.

On the question about the 930 vs Carrera rubber lip.. They are NOT the same thickness at the mounting surface! Been there and done it.

If you dig out images of the 2 965 turbos that ran the IMSA Super Car Series in the early 90s you will notice that they snuck this mod in. A Carrera lip on a 965/930 base. This gave less rear downforce [by about 100 lb at speed] but less drag.

If you look really close at some images of the cars or see one in person, you will notice: The top surface is a perfect match. However, there is approximately a 1/3" gap between the lower portion of the rubber and the built up support boss on the fiberglass tail box. If you don't look close it is easy to miss.

When I was building my original CTR inspired car in that same period I had both tails and tried this combination. I liked the cleaner look but couldn't stand the up close mis-fit. Very time consuming to modify the box section for a 100% fit, especially when I wanted to run the "proper CTR" rear end in the first place. I finally used the complete 930 tail to gain a bit more rear downforce as I really used these cars in those days. The addition drag was a non-issue in good 'ol California as I never-ever drove over 55. [Yea. Those were the 55 mph days]
