Does anyone know if the spring cup dimensions are the same, as in would a set of springs designed for a Cosworth be the correct length and therefore height, or would they need to be longer / shorter?

 

they will fit, but the spring rates are different due to the wieghts of the engines

i think that the cossie springs are rated higher but are shorter while the 4i springs are ongers but softer

does that makes sense?

 

that should say "longer but softer"

 

are you refering to standard springs mike

 

I just wanted to know what effect fitting springs designed for a Cosworth would have being fitted to an XR4i? They are fractionally lower than normal at 15mm on the front.

As in, would they be too short or would they sit okay?

 

...oh so you bought that XR4i then Mike


..oh and yes i accept your offer for my neons...your little girl is gonna think your the coolest dad around

 

the spring rate for the cossie is (from memory) 140lb/in and the one for the 4i is (again, from memory) 105lb/in
but the cossie spring is shorter so that it won't compress as much
the 4i spring is longer but softer so it will compress more but it should be the same ride height

as someone who knows a tad more than me about what this will do you'll probably find that the cossie springs will firm up the ride in the 4i but it may sit a bit lower than normal overall

 

One car has a Cossie lump fitted and the other a V8 . I just don't want the cars to sit too low and for the springs to be overworking the dampers by being possibly too short .

I was hoping that you would say the actual damper lengths that the sprongs sit in are identical , that would make me VERY happy .

Many thanks for taking the time to post .

 

I changed all my 4i suspension over to a Koni kit for a Cosworth.

So i cant help

What you doing with the 4is Mike ?

Steve.

 

They aren't both black and on 7 spokes are they?

 

Trying to help get the cars to handle (it's Pete and Mark ). This maybe the way to go if the height isn't right .

 

I've only seen pictures of one (Doh AKA Pete's).

 

Any tips would be good

Mine has standard cossie ride height springs, poly bushes and a cossie front ARB.

here's a tip buy an evo

 

as far as i am aware the rest of the strut is identical (but very spindly looking comapred to the 4wd stuff i normally see )

the 4wd springs are margianly different again to the 2wd cars but i'm not sure how much sfitter they wuld be as they have to support the extra weight

which V8 is it under the bonnet? if it's a rover they tend to be the same sort of wieght as the cossie anyway but if it's one of the other forign imports then it's a case of trial and eror

 

It's a Ford Smallblock 302 I think
