Going back to rear springs, we ran single leaf, decambered and then adjusted stiffness with dampers. You can also run a lowered ARB if you use the fabricated drop links. Also it was permitted to use the fully floating drive shafts. The more leafs you run the more weight you have to control.

We ran up to 4 degrees negative camber, depending on tyres and a lot of negative castor. This was achieved by offset front ARB mountings. Also we have specially fabricated top mounts which allowed for both camber and castor.

30 seconds of toe-in.

For the engine we had specially designed pistons by JE.

Yes we used the power steering rack.

Voiceless… which doesn't mean I dont thank! I have to find out why each time I go for a lot of negative castor, she gets worse in the corners entry leading to hardly reach the apex. Manual states negative castor is 0.5 to 1,5°, going more than 4.5°/5° gives a lot of understeering atm.
Till now couldn't get more than 3° neg camber with non adjustable TCA's (Yoko or Toyo tires).
Was the use of fully floating half shafts a consequence of the remplacement of the drums by discs?

My first set of pistons was bespoke Arias I think. No Accralite available in the std bore dimensions (they are said sensible to overheating). The piston question is touchy because of the class limit.
I know you understand my - very - bad English what I mean is that if the chosen pistons need a huge clearance the risk is to land at circa 3034 cc… They check the bore not the piston diameter which is normal. Same thing with many others 6 cylinder, any overbore on a 2L 911 will send you above the mandatory 1999,99 limit!
Thanks again, you pointed the right "direction" giving me work for this winter. And may be more! Please go on.

PS You're a Chef and "King-Ford"! Hence the use of their briquets. I like your recipes, both food and Capri!

You get more understeer with castor in slow corners so you have to use the rear end. Castor is for fast bends and straight line stability. For additional camber we used the adjustable top mounts to fine tune the camber.
As I recall we ran about +30 thou bore. We were certainly within the permissible volume.

Indeed. Using the rear end is not so difficult, seems there is another steering hidden there! Did you adjust your settings depending on which track you were using? I guess 30" of toe in or zero is barely the same.
Right again, + 29 overbore is within permissible volume, less than 500 cc per barrel. I see that all Ric's engines' capacity are checked and sealed by Motuk official scrutineer now. A very good thing imho.

Running parallel front end is not good. As the car rolls the outside wheel points out, instead of straight. It also depends on the ARB setting but as a general rule toe in is best for RWD. Parallel for FWD.

Yes we adjusted damper and steering settings depending on circuit.

These things were permitted for the Capri whereas they aren't for the Rover. All due to the manufacturer certificates presented to the RAC by Ford but not by Rover.

Dont think I'm thick head here (agreed, I often am…) but does this mean that each model or/and make had special agreements to compete in the Grp1,5 category, meaning that its hard to be understood if you're not deeply involved in?
Short words: you keep your ex-works SD1 as was in period, compliant, having a new HTP form filled from what you have not what you could have. Right? If any other SD1 was legally more developed than yours, engaged in an international series, proofs of period brought, all legal, you could have yours to the same state of tuning (may be have to change the livery?). Right? Could you keep the same HTP front page with only red pen marks written by an official scrutineer after this kind of alterations?
Apart from Blue Book, do you know someone ready to supply a copy of what Ford got from RAC and how much it would cost?

As to your Rover I consider being a piece of history, its not about what you could do but what you're allowed to do. Keeping her as was is a respectable and courageous choice, you dont go the easy way. No misunderstanding here, I hope. Yes?

Remember this was for the BSCC but yes, the certificates provided "enhanced" accessories such as those drop links, 48IDA etc. I've seen copies of the certificates produced by Ford. Some of those were later homologated for Group 1 (that carb again). I believe only Ford produced them at the request of the teams.

Yes as was remarked at Oulton Park, my HTP has no red marks, and the engine is sealed.

I know Martin Thomas has some but he was a constructor. Not sure he's willing to sell them though, he's always worth talking to though for reasons other than these certificates. Again Ric W will have some copies, if not an original.

Understood. As long as the punters realise the differences and that's always a problem hence at Goodwood it really isn't competitive anymore.

I can't imagine your feelings when at Goodwood. Keeping the Rover as she is, you have no other choice than have a good weekend forgetting about victory. Match a pro lap time same day, same track, same everything brings proof in the pudding. I had the immense privilege to share a - very bad - L'Tina with Simon Hadfield and I can tell you that more than one month before all my nights were short ones… in spite of my experience in endurance where your first "enemy" is your team mate. I'll go to Ric he knows my car and my face but its hard for him to relate those to my name. Anyway, I've absolutely no past due there! Few months ago, I sent him a copy of our regulation and some others too.
Tanks for your help.
Still I dont understand why in my country they dont want to adopt your regulation. On the contrary, they went for Production '81 rules, not one of the best year ever…

Other mode:
what will be your New Year eve menu, Chef? Spare ribs with apple juice may be… Dites nous tout pour que nous ne restions pas sur notre faim!

No 2 Toyota engine up and running sounding sweet. I've had pistons machined and just this minuet run her up much to Mrs Delta annoyance. Rolling road but probably not until I get back from lower hemisphere. Then if all is good and I can earn some money this year I will enter Louis Historic F3 Cup race at Zandvoort.

Broadspeed 1300 Escort

So far we have rear axel , I’ve located a shell in Belgium which we can collect when I get back from Oz . Just on my way back to work with a 1760 BDA. Hmmmm might change my mind about the 1300 idea .

Good on you, Iain.

Now you can create a proper Escort; a Special Saloon!

Won’t need the shell then! Probably cheaper to build a space frame and hang a few fibreglass panels on it. Guess you’ve got a few single seater suspension bits lying around as well....

Coincidentally Canary’s shell came from Belgium, rot-free in all the important places. Strange as they their winters are no kinder on cars than ours...
