RS2600 Rear suspension
Can anyone tell me if a 73 RS2600 Group 2 car used a sway bar in the rear in conjunction with the Watts linkage? Thank you.

Hi ferguson. If you go here http://historicdb.fia.com you can download the homologation form # 1609 free consultation non official use only. If you look at appendix J end of period and K I guess you can find if you're allowed to fit a sway bar unless anti roll purpose only.
If you're in the process of building this http://www.borremanscollection.com/m...8#.XGKFHi17Qhs a nice recreation was displayed at NEC few weeks ago on the stand of a renown English specialist May be you'll be asked to bring proof of period. I guess you're not building a AWD model? You've got a PM. Last edited by Gerard C; 12 Feb 2019 at 08:55. |

Appendix J 1972 Art 260 (n) states that a ‘stabiliser’ (includes ARB, radius arms, panhard) is allowed to be fitted even if not originally present. It also says ‘even if this stabiliser serves other purposes’.
So no reason why an ARB wouldn’t have been fitted, and I’m pretty sure they were used. Certainly the RS3100 had one at the back. That of course doesn’t answer your question definitively. I will have a search through a few Ford books just in case there is a period pic.... And if you haven’t got conclusive proof by the end of March, I’ll look under all the RS2600s racing at Barcelona and have a count up...... |

Rear sway bar
Thanks Mike and Gerard for the reply. I talked with a guy I used to work for over here and he raised the question so I was just wondering if it was needed.

I found a good size cut away drawing in ‘Momentaufnahmen’ of a ‘72 car and you can see the radius arms, Watts linkage, dummy leaf springs, but no ARB to be seen.
No more conclusive of course, and I will try and remember to check out the Capris at Barca..... |

Mike is much more knowledgeable than me of course c'est normal je suis plus jeune de quelques mois! Among the very nice parts spotted at Birmingham, the wonderful hubs for peg drive and a very nice air duct for the intake, breathing from the upper part of the front end gril then going under the bonnet. Using a Mk1 facelift front helps sometimes…
Mike, the dummy rear leaf spring was plastic if I'm correct? In this case, to be compliant either the plastic has been homologated or legally used in period or you have to use steel as stated by appendix. I'm wrong here? if wrong, correct me and I'll buy a beer! |

Yes, the dummy springs were some sort of plastic or fibreglass. Likely we’ve moved on in technology so far since then that the material is no longer available! Don’t tell anyone but the ones on my car are plywood.... Anyway, we’re going off topic. |

Another advice "linked" to the thread is never ever have a too low rear ride height. Take care if you just copied a car from pics, it is said by some who know that the upper tramp bars were slightly too short to work properly… Before fitting the shocks, make sure the axle can move freely on all its travel. Same thing when adjusting the Watts Right Mike?

There were no anti roll bar in period and you can't use one today either, this for the RS2600 or RS3100.

RS 2600 Rear suspension
Thanks Guys very enjoyable reading and good info too. I have an e mail in with Ric to see what he might say. My understanding of the FIA rules was that if the car had it which the Capri had originally at least over here that it was okay to use for racing. Looking at some of the pics of Group 2s going at speed around corners it looks as though the rear wheels have much more movement than the frt end which leads me to believe that they weren't running a rear bar.

RS 2600 Rear suspension
Thank you Duddha for the info. It's not that I would run a ARB in the rear I just wanted to make sure I was doing the right thing as I have no ARB in the rear at this time. Thank you for your input Duddha. Not alot of Capris running over here. My old boss Tivvy Shenton didn't think it would but I needed more input to be certain.

Ferguson, as to what works driver said about this car:
https://www.motorsportmagazine.com/a...r-vs-batmobile Have the front end working is piece of cake, have the rear end too, but having both working well together is another story. Unless you think that guys like Fittipaldi or Fitzpatrick didn't know much about racing cars…*HTP'd and compliant cars are competitive and fantastic to drive here, you and your folks will have fun with. Enjoy! |

Ferguson, just now your name rings a bell in my frozen brain. We already had a chat, was it one or two years ago? You still have some Capri very rare parts, including a Ferguson transmission, right? Your daily is a Capri euro version or a Mercury may be (rusty because of road salt)? And you do know Montpelier for sure !

Again good reading. I have read and understood that the Capri was a hand full to race. My old boss was one of the people that looked after Fitzpatrick's Capri. In my mind I love to just look at the car. It has some great lines.

Well put together the Weslake RS can be enjoyable as you can see here
https://www.youtube.com/watch?v=G0POTtCCig4 Quite different from a Grp1 3.0 I must admit… Depending on what you have/want a 3100 is the weapon of choice. And Ric is an enthusiast totally Capri'mad! Enjoyable, knowledgable and great driver. Have a look to the hubs he is machining at CNC, may be under the name of Weslake the company he bought a while ago. |

Yes Gerard We exchanged messages less than a year ago I think. I have a complete but extremely rusted 72 Ferguson and also a 73 Capri that someone installed a turbo on in 1975 reminiscent of the May turbo.

The Capri was a very popular Group 1/ 1.5 etc race car - a bit surprising if it was so tricky to drive. |

Andy we're talking about RS 2600 Grp2. The base is the MK1 and face lift. What is said is that in time the works cars suffered a lack of development. Things went better with the 3100, same base but more development.
BTCC Capris were/are based on the Mk2/3 chassis offering a slightly better track/wheelbase ratio. The combination between narrow tires and less power is less demanding. When guys like Fittipaldi and Fitzpatrick say they were tricky, either you think they are pussies or you try to find a better suspension set up; dont you think so? Or you buy a CSL! Strangely I can't find any comment from Sir Jackie about that but I guess bauble can tell you why. I know you'll have a much better opinion now, just a wait a minute and you'll know more and better…* |

Sorry I've not been clear Andy. You probably will forgive me, now you know how bad my english is. As were the first 2600 RS, at Jarama they couldn't match a good Escort using almost the same parts. Lack of development and, from John F words, terrible ambiance in the team at one point.
From you-know-who words, you must not go to low with the rear end, this creates a conflict between the center of gravity and the roll center. We have almost the same thing with our 951's, mine is soft at rear and I use the Cup rear ride height if not slightly higher . The RS used a four links axle plus a Watts linkage, no need for a sway bar IMHO. Why the ex-BTCC cars based on Mk2/3 chassis are so good, is hard to understand. If you look at the rear end, the Atlas axle is only held by two 8 mm bolts going cross the leaves springs, the four original U bolts and a thin sway bar. Hence the term of "living axle"! Dont ask me more, they are much more competent people here and I love this car which sometimes blinds me. Les yeux de Rodrigue pour Chimène ! The results in actual HTC series leads me to think that a Mk3 Grp1,5 (de Borman is a very good driver) could be very close to a 2600 Grp2 if you used the same size of slicks tires. |

At the risk of derailing Ferguson’s thread, main reason the RS2600 was ‘a handful’ was lack of rear spoiler! Terrible rear end lift at speed. Homologated for the RS3100.....
