Has anyone got these on there cossie just putting mine back together and thinking of getting some for the rear, just wondered what size and poundage people are using

 

Just get really soft ones. That's what I did. All they are for it to stop the spring dislocating after all.

 

It's best to get ones that compliment the spring rate already used. They are there to stop dislocation but if they are too soft they won't react fast enough to fill the void. Match them correctly is the best option, that way they will fill the void when needed and "help" the main spring. Dual rate springs in effect.

 

Go to coilover supplier and get helper springs, no need for poundage, as when car is on its wheels it is full compressed.

 

I work at Leda suspension and trust me there is a need for the correct poundage or they do not work correctly. Not arguing just telling you fact! Otherwise they would all be the same rate and thickness.
Whatever you choose to do make sure you reset your geometry. A 20lb 50mm helper will fully compress to about 13mm a 100mm 70 lb will be about 45mm or more from memory.

 

Is there a difference between Helper and Assister springs?

 

Depends in what context we are talking. Basically helpers help fill the droop gap and assister springs help the main rate spring. The problem with fitting the softest helpers is that a main rate spring has a mass. If the helper is too weak it cannot react fast enough to fill the droop void, so dislocation still occurs. Too heavy and it won't compress. Best thing to do is measure the droop gap then return damper to manufacturer and have an internal droop stop fitted

 

Will measure up and take it from there cheers for the help felas

 

Thought so.
