coilover spring

[mrtat2k9]

what size and stiffness coil over springs do you use im using 9 inch at moment but can seem to get car low enough any help more then welcome

[Error404]

you'll probably need 7" and helpers then.
I'm running 60n front and 70n rear

[mrtat2k9]

What do you mean by helpers and what 60 and 70 n mean sorry for all the questions but new to coilover idea

[Error404]

60n is the spring rate
60n/mm ~ 342lbin

Helper springs take up the slack so you can run a shorter spring and it does not unseat when the suspension is unloaded: the second skinny little springs at the top. when the suspension is loaded they bind and the main spring does it business.
