Hi Carl

third pic is a car thats in France, its painted up as a Texaco version but we believe its more than likely an eggenberger customer 500 instead, those arms appear to be the Ford Cologne mag type.

The fourth pic is the white BBR/Rouse hybrid that oakfields have for sale, so they could be either BBR or Rouse spec steel arms, diff looks to be a Harrop one

Here are some Rouse arms from the Harvey labatts car, best I have come across sorry, I plan to get loads of underside shots at this years Silverstone classic

Great weekend for race RS500s at the Silverstone classic.

I took a look under most of them. All the euro cars were still running the ford 9" but the surprise ones were the two BBR cars, they both ran a Harrop diff from new. Dave Brodie actually blew his on the way to the event and had to cobble it back together with a meagre spares package so his mechanic told me.

DJR1 also runs a Harrop and I had a good chat with Andy the owner and he said DJR used alloy copies of the magnesium cologne rear arms as opposed to the steel type most UK cars used.

Here are a few photos, all my own this time:-

Lots of coolers under the Labatts/Rouse car, was it the same for all his cars? Difficult to see in the first picture.

Still no pics of the front?

This is what gives away which type of diff is used...

The pits were very busy so rear end shots were the best I could get sorry.

I think only his own cars and the Labatts had the full Rouse cooler set up, the customer cars were more basic

Pics look good Paul, thanks for putting them up.
Looking for more detail on the inner pivot on the steel arms, looks like an aluminium block with spherical bearing bolted to the modified end.
Seems this aluminium block comes in 2 lengths that I have seen (to move the pivot back towards the front of the car, RS500 mod?)
This aluminium block can also be packed (shimed) to give camber adustment.

Thanks again
Carl

Carl you can buy revised rear beams and arms here in the UK from a couple of fabricators for the road cars, here are some pics as I guess they use a similar system to the original racers. Getting close shots of the racers would be very hard unless I can find a friendly owner, same with the front of the diff shots as they sit up in a well so difficult to capture at ground level. If you want supplier details I can let you know. They tend to be around the £1000 mark to have made. This is an ahmed 6 degree version

You've got all I need to see of the front of the diff in that shot...

Clearly not an American 9".

Hi Ray, the last 3 shots are all road car equipment not race sorry. That diff is the standard 7.5" lsd ford unit the 2wd cosworths came with

However it does show that it's not too hard to get a photo which will show which diff is installed...

If it had been an American 9" it would have been clearly seen in that picture.

Thanks Paul, looks like the Brooklyn car has this type of arms.
Mine came with the magnesium arms, and I doubt TDR would ever had them in 1989.
It only ever had the 4 stud wheels as well.
My aim is to make it as original as I can.

Cheers Carl

I did not take the pics, just found them for Carl, and that car is clearly up on a ramp. Next time I am under a group A RS500 thats up in the air I will make sure I take a photo :)

Carl, from what I recall TDR used the rally version rear end, like this set up in the pics, hence the 4 stud rather than centrelock

Hi Paul, Yes this set up is exactly how my Group A RS500 came, but I think TDR would of used steel type Rouse arms with 4 stud hubs.

Do you think there would be any way to contact Terry Drury or anyone who worked on that team?

One of the cars turned into the black Nigel Mustell Thundersaloon RS500 Sierra, would be good to talk to Nigel or the current owner

Cheers, Carl

Theres a great book out there called"How to prepare the Sierra for motorsport" you might find it on Amazon. It covers all variations, mainly the rally cars. The group A 3dr rally cars started with steel arms then moved onto the mag ones with the round beam then finally a square beam with mag arms. This continued evolving right upto the wrc escorts which then went for a cradle type set up.

Your cars evolved through a number of specs itself so hard to say its definative one I imagine.

Terry Drury used to advertise in Motoring news but I think he has now retired. Put a shout out in a seperate thread on here and theres a good chance someone will still be in contact with him.
