A few questions for those with high powered cosworth's regarding the best setup for over all handling on the rear end?



1)Is the GrpA Square beam the best you can get?

2)what are all the parts needed to be able to fit the complete setup to a 2wd Cosworth?

Who has this item fitted and any pics?


Thanks in advance.

The Mag setup may crack on the Rally car it was designed for due to the harsh treatment it takes every time it is used. However on a Track car would this still have the same issues without the hard wearing off road abuse? Is the mag setup legal for road use?

Side exit i dont mind

See my resto thread in my sig

It's not a square grp A one

Don't know what is the best you can get tbh, i've got a stg1 adrenaline beam (adjustable camber)

Danny is fantastic to deal with as well

Anyone got a link on what beams there are? pics/options/advantages/prices etc

I had a look at your restore thread and the beam you have does look good. But compared to the GrpA type is it better?

bud-weis

obviously you're looking for maximum adjustability form whichever beam you get....but you may also be wanting to save weight too.

The Zoo beam i have used is fantastic, it's heavy though but very strong. The geometry stays spot on under full droop etc.

I have only seen pics of the adrenaline beam...it looks good but i have to agree with others that it doesn't look that strong....although Danny B says it is! it's more expensive than the zoo beam too.

The square beam i would guess is much much lighter, especially when you are using the proper mag arms etc...and if it's good enough for rallying then it must be good!!...i expect you need to use proper uprights and other bits and pieces though, meaning it may work out pretty dear.

I haven't bent mine yet

See my resto thread for pics of it fitted

The square beam/mag arm set up is good, but most of the avaliable parts havehad a hard life
The AdrenalineZoo/Ahmed set ups are a better option as they allow you to use a normal exhaust and also Danny and Brom can adapt them fopr different diffs

bud-weis

Agreed

for a road car i think either beam is a fantastic upgrade from a standard beam...and for an occasional track car

Danny B knows what he's doing so i dare say you'll never bend that beam...i bet i could though

And as you say the Square beam/mag arms have been abused for years..and the arms corrode badly too don't they?

NO not by far

Can you tell us why, it would be interested to get more points of views, as I am interested as well in the back of my saph.

i think what gareth means is grpA reg restricted how far they were aloud to be modified and a 9 degree angle was set.

I think according to some 6 degree is the optimum, personally i have no experience of a 9 degree on the road so i cant say, but i think its more than just the beam that needs to be sorted.

so you could spend a grand on a nice custom beam and then have it let down by, shit suspension, cheap tyres, poorly setup geometry etc etc.

So many factors affect the cars handling its not just 1 sole thing.

Ryan

oh and micheal u dont have to have a side exit with a square beam, granted the exhaust needs to be modified to suit the new beam, but i think you'll find 95% of after market beam need the exhaust modifiying due to it fouling on the longer pickup points.

GARETH T

what ryn said

CharlieSaff

Have you seen pics of the tubular beam on Danny's website for the best you can get!?

Mad Matt

iTrader: (2)

Yes I agree, but the group A regulations were quite "free" and they made several type of square beams, for each type of surfaces (gravel, tarmac, fast tarmac, ...) so why shouldn't it be the best ? They used them for years before the rear cradle system aka 9097069 so I would imagine the ultimate rear end system would be a tubular system as used on many of the wrc cars now, but it would be great to have an opinion of ex or current rally drivers who used to drive real group a cars.

But the worst thing about square rear beams is their mag parts, I assume they are just as breakable than mag wheels + as it was said, they had hard used along the years.

anyone got any pics or prices..?

Rear square rear axle complete with arms, hubs and wheel nuts, between 1500 and 2000 pounds depending of the state.

EDIT : I am talking about group a stuff.

anyone got one going cheap

Ahmed beam is the one i will be going for i think.

I have had Mark and Ahmed adjusted the camber and toe on my standard beam using various shims etc. Although not the ideal solution its transformed the handling and for the fraction of the cost of a full beam which i cannot afford the the moment.

I should imagine the WRC style setup Brom made for his 3 Door would be better than them all.

Some great info comming to light now.

Any more thoughts on the subject would be great. I need to sort out the rear end of my motor so what ever the best way forward is the way i will go..

What brake setup is needed for the GprA Rear end. Will it need a Hydrolic handbrake? Will it work with AVO coilovers which is whats on the car at the mo..

Any help would be great.

Depends on which setup you want to go, tarmac, gravel. Gravel for example used to have 16" wheels with 315mm discs and 4 pots calipers. All serious rallycars does have an hydraulic handbrake and for 4wd the best (and unfortunetly very expensive) would be a clutch release for the handbrake, but well be ready to spend fortune there, and it is only the rear of the car mate.

Whats that supposed to mean? Ahmeds beams are £1k as i asked yesterday when i was talking to him. Mods are done to your beam aswell not anyone else's piece of shit thats been given in exchange.

Mad Matt

iTrader: (2)

well I would also consider ZOO's rear beams, they do have 3 types and I only heard good things about them.

And less expensive.

Nash

iTrader: (3)

Zoo or Ahmeds beams are the ones i would go for tbh. Ahmeds been making them for years as has Brom. Not saying theres anything wrong with Dannys beams its just they have not been around aslong.

Mad Matt

iTrader: (2)

Yes yes I know mate. Well the choice of a rear axle is quite hard to do due to the customers beeing all happy with them whatever you choose I don't you'll be disapointed, but for ultimate performance I still would consider the real group a stuff the way to go, altrough I ain't as expert as the real experts there.

If my car was just a track car then i might look into it. The thing is it gets used more on the road than the track, so my cars allways a comprimise or good road and track handling.

Surely 6 degree's is 6 degree's regardless of who makes the beam

Speak nicely to Tom, he'll make you one....

iTrader: (3)

so there are 3 to chose from, what are the price options and what do they do?
and how many are exchange?

Mad Matt

iTrader: (2)

I assume you are talking about ZOO's beams, if yes, then the best is to ask Brom :

Brom's road beam is £550 (
Strapped is £650

and i think there is another version or two.

Ahmed beam is around £1000
Danny B's i'm not too sure tbh...but he has different options available.

Not too educated on beams but I have been in a 2wd saff which has an ahmed setup, and the way it controls is absolutely awesome, it handled brilliantly i was very impressed, so another part on my shopping list it seems lol

dojj

iTrader: (3)

the problem is that i have an estate, and the suspension pick up points are slightly different in relation to where the struts and springs sit so i don't want to fork out loads of cash only to find it doesn't work because it's different

if you see what i mean

the arms are different but the beam is the same so i'd have to provide estate arms to be modded, but they've got to be matched to the sturs i've got because they are different on the normla estates because of the bolt spacing on the bottoms



i don't have any camber issues, but other peole who run estates have loads of them so i don't know what the difference in mine is to theirs, i don't want to have to remove the beam off of my car to send up, but theren again, i don't nwat to give another beam to mod and then find it won't fit back in again or hasn't made a difference

What advantages and disadvantages are there on running a solid monted beam?
Its on a road/track car where comfort isnt an issue but thats because there isnt any comfort already lol.
