Which Helper Springs - AST Coilovers

[GasManLS7]

Hi guys, looking to get a set of of AST coilovers and need to run them with helper springs on the rear. Anyone know which ones would work best?

Tried asking AST?

Pretty sure they already come with helper springs.

The ones that take up the slack of the main spring when on full droop 😉

They sure do. 😎

I mean ones that go where the standard rear springs are. Picture above just shows the coilovers?

Nothing goes where the stock rear spring is, they're redundant when you run a full coilover such as an AST.

They're needed in road going class. Any hill climbers on here?

Sorry didn’t read the op but on @frayz picture the rears do have helper springs

I don't mean helper springs on the damper, needs a separate spring in the original position too.

Can't see that working at all.

Probably best to go for a BC coilover on the rear instead, which retains the standard shock and spring setup.

Works pretty well on this, 67.3 is quick. It's the only way to use coilovers on the rear in road going production.

Believe this had it too and was one the fastest Clios I've seen:

AST will make you a setup to run separate shock and spring for sure. I'd enquired about going to that with the Megane

Dont they do one already? Its a road setup though.

Its straight forward to work out but if you are looking for a kit like that on the facebook forum someone is selling a custom MeisterR GT1 coilover kit with the setup you need already. Its a good bit of kit and only has testing miles on it.
In short you basically double the spring rate in the standard position so for the AST coilover designed for 80nmm springs you want roughly an 160nmm in the OEM location. Due to the way the springs work i'd run a tad softer if you are stripped out - maybe 140nmm. It will need to be custom wound so getting the ride height worked out may be your most tricky issue though if AST have that worked out happy days.

Cheers man, just the info I was looking for.
