Setting up Suspension

[Johno]

Thanks guys for all your advice.
I guess starting with the Sierra based settings is the way to go for a start.
Hoping to get the car on the floor soon so I can see what I've got.
Forgot all about spring rates John.
I got the same springs as you from SSC but IIRC you changed the rates?
I haven't got a clue where to start to sort the correct settings for these but the guys on Locost forum keep going on about Procomp to set up your car properly, but that costs around £250 I think and based in Birmingham.
I'm guessing the MX5 version should have different springs to the Sierra because of the weight issue but where do you start?

Jason82 do you know what GBS fit to there cars for the MX5?

If we can sort out this between us it would be a big help to new MX5 builders for the future as the Sierra is becoming endangered donor

Hi Phil, you added your post while I was typing..LOL. Where do you think we should be looking regarding spring rates. Now you are a convert to the Dark Side your input would be most grateful.
Lets see what we can come up with and pin it to the MX5 dedicated page.
Thanks again guys.

It's more to do with the change in leverage than the weight (I'm guessing they're not that different weight-wise).
The upper rear wishbones are much shorter on the Saturn than the Sierra so the shocks have much less leverage and therefore need to be stronger to have the same effect.

Sort of - I ended up with 325lb springs as someone was selling some nearly new ones for a fraction of the price of a pair of new 300lb springs
I'm currently running 325lb on the front and 400 on the rear and I'm not in a rush to change them again.
Not saying they're the perfect spring rates for the Saturn build, or suggesting anyone else use them, but they seem to be working well for me at the moment.
I might drop both ends by 25 to 50 lbs next year though as it's possibly a tad too firm for some of the crappy roads I drive on

Hi Mick,
I'll have a look around tonight on the bay of thieves...
I'm going to try and sort out how much caster I have but I bet that's awkward to measure
I reckon I've got nearly 9 degrees (eyed it with digital angle meter).
