which cosworth rear beam assembly is best grpa spec, zoo motorsport spec, or rs500 spec one not to bothered about price just want best traction and to be able to take a big rear diff so which is the best and why

 

Speak to Cossiebrom

 

ahmed or zoo boys

 

no i dont want to talk to people who produce theses beams coz they are biased to there own parts im after people who actually use the parts on and off track

 

What do you want to do with the car it'll be fitted to, what power will be going through the diff, these are all important factors which could make one more suitable than another.

 

 

i want 500bhp+ from my next engine and it to be able to handle serious abuse

 

John,

I would say ZOO beam for a track based car - after much consideration, and looking at rally spec tarmac beams, round beams, square beams, so-called Group A beams etc........... I eventually went for the ZOO one.

You'll find the lads there are quite objective, and if it's no good for your application, they wont try and sell you anything..........

 

what do you call a big diff?
if going 9" then get a proper wide track square beam with mag arms etc.that way you get proper drive shafts and not just road ones.
thats what i use and mines as group A as you can get.
