I'm looking for some advice on what spring rates for my car.
It's a mk 1 Escort and I'm fitting coilovers to it but not sure what spring rates to use, it will be mainly a road car with some track use. It's got a cosworth engine in if that makes any differance. Any help would be usefull

 

might want to try over on this site Jim

best of luck.

 

i would say 180lbs mate.

 

its been 6years since mine was on the road but i was running 300lb on the front and 220lb on the rear.but this does put some load on the shell, so unless you have a good fitting roll cage you will start to get stress fractures in the roof pillars.

 

What size diameter ??

Its impossible to quote rates without knowing some basic info

 

2.25 on mine but nuts is correct lots of things to consider ive got compresion struts on the front and no anti-roll bar,four link on rear with watts linkage

 

They are 2.25 diameter the back is four linked with a watts axle, front has both ARB and comp struts. The car is not caged at the moment but will be at some point with a full weld in group 4 type.

 

if your running a front roll bar i would go a little softer than the 300lb im running but get the cage in before you push it too much

 

i,m running 280 on the front and 200 on the rears, front end has adj tca,s and comp struts, rear end has been 6 linked with narrow atlas and also the cage was a s,d bolt in type now welded into place with the rear bars replaced with longer ones reaching out to the rear turrets, then cross linked for extra stiffness, as youre mine is also a mk1 with cozy and for fast road and track use!!

 

thank's for the advice
