😂No, not too far off original, but should be enough. Find out in March😉

600lb Cortina Spring Rates!!
Following the tangent on Baubles Photo thread I was interested in why Cortinas with such stiff front springs did not understeer like mad?

Don't forget to add in 1" or even 30mm ARB's
7 degrees caster may have something to do with it, std geometry obviously. I think mines about 500lb and 24mm ARB . . . All of my teeth are still attached. There must be a correlation between suspension settings and bodyshell/cage prep. I gave up some years ago now so have no idea what the latest craze is. BoT . . . only winter project I've done is fit a spot lamp on my Lambretta because as stylish as BErtones design was, a rectangle headlight is rubbish for projecting light! Oh, I did build a new 240cc engine for another one as well. |

Nice Lambretta. I guess the average Vespa user totally ignores what he's missing! The Rumi was fine too.
Finishing to refurbish a crashed MX5 with few enthusiasm because the specific regulation doesn't allow to adapt a more track adapted final ratio. If you loose the 5th gear, you won't even notice! Re the caster I'm too old to cope with such a figure on a real Mac Pherson suspension. And this kind of front arb diameter is more useful when building a house… Original geometry on Capris gives 0,5 to 1,5° which is too few but gives an idea of the starting point… Lotustwincam, I'm with you, this is a tangent!!! |

Lotus Cortina had 3 degrees in period for racing . . . . with standard parts it's about 1. I have 3 . . . . no idea how you get 7 and everything still moves! the top mounts tear to pieces . . .unless they are spherical bearings
Mot Rumi was a quality machine, the competizione won the 24hr Bol d'Or 3 times ? |

They did not understeeras the Yokohama A008Rs that we ran from 1990 to 1996 had so much grip and as the Cortina is quite a tail happy car balancing front and rear grip is relatively easy and the large diameter ARB helps too. Mine was 15/16ths inch. Today many go much bigger, 25 to 30mm now the norm. The LC had a 7/8th inch ARB as standard with 15/16th as a homologated alternative. Preppers today go bigger saying the ARB is a spring and spring rates are free under current App K regs. Although made of spring steel I disagree that an ARB is a spring. The Yokos needed massive camber to make them work well which made the cars look very much out of period but they were good tyres for quick laps and much quicker than the Dunlop Historic M and L section tyres we changed to in 1997. As an example I could do 2-01.8s at Oulton Park on Yoko A008Rs but my best on Dunlop Historics was 2-07.5, nearly 5% slower. However, the Dunlops are much more fun to race on. |

I seem to remember that any time, any appendix, any series, any country, any car, the arb's diameter is/are free. Going from plain to hollow design is forbidden.
As to the wheelbase, I can't see how you can move an axle staying compliant though… But there's a rather fair tolerance. Seems that on some LC's, the rear wheels are rather difficult to extract without removing the shocks! Last edited by Gerard C; 6 Mar 2020 at 14:39. Reason: Wings spats! |

Terence, are you looking for Tillet seats? Hard to find a dealer here.

It may just be hearsay but I understand there are moves afoot to police this aspect of the LCs currently on the grid and being built. Watch this space, or that one over there.

Where in the FIA Appendix K regs does it mention that ARB sizes are free, Gerard? |

Good question of course. I remember several appendixes J, I'll check a K and I do remember Simon Hadfield mentioning that here. Going with Peter, I do remember Simon saying he has the original manual allowing to accurately locate - at least- the front wheels in the engine compartment/ inner sills. Simon's knowledge is huge and Leo's car was really fast.

Probably the reason why the arb's diameter is free is because very few homologation forms have this precision. Stand to be corrected by Peter at least, but the Capri had over the years rear arb going from 10 to 14 mm. Capri again, the Mk1 track is 100.8 ", 2560,3 mm with a tolerance of +/- 50 mm.
LC wheelbase is 97,5", 2476,5 mm with a tolerance of +/- 22 mm if I'm right. |

Have a look to appendix J 1965 , Chapitre III, Groupe 2 Voitures de Tourisme améliorées, Art. 263, 21 Stabilisateur:
est autorisé le montage d'une barre stabilisatrice du commerce ou barre anti-roulis, ou système similaire. Sorry but this language is my mother's tongue and one of the FIA official… |

I checked the 2020 edition of the FIA App K regs on another post in this section and the ARB is free, so I was mistaken. Has this changed recently as I'm sure last time I looked, several years ago, ARBs were not mentioned specifically for Touring Cars. |

Regardless of the diameter that is specified in a particular series a good friend of mine did the original Escort Mexico challenge back in the 70s. He had several ARBs made out of different strength materials that were all the same diameter.
