Clio suspension measurements.

[mikeh]

Does anyone know some or all of the following measurements for a 172/182?

Track Width,
Roll Center Height,
Unsprung Mass,
Coil Spring Rate (rates for Cup, Non-Cup, Cooksport and Eibachs would be handy!)
Motion Ratio,
Bar Outer Diameter,
Bar Wall Thickness,
Bar Length,
Arm Length,
Bar Motion Ratio.

A friend is developing a free web app to calculate various information useful for tuning, and has agreed to add Clio specific stuff if I find out the information.

I'm sure I could measure, weigh most of this, but thought I'd see if anyone had the information already?

I have some of the data from a quick search.

Track Width: Front 1430mm, rear 1408mm
Roll Center Height,
Unsprung Mass,
Coil Spring Rate (rates for Cup, Non-Cup, Cooksport and Eibachs would be handy!):
Standard:
182: 24.3/50.4 NM/mm F/R
182 Cup/Trophy: 31.9/56.5 NM/mm F/R
Eibach:
Front 18-27 N/mm; 160- 239 lb/in progressive
Rear 40-85 N/mm; 354- 752 lb/in progressive
Motion Ratio: Front: 1:1, Rear: 26:39
Bar Outer Diameter: Front: 25mm
Bar Wall Thickness,
Bar Length,
Arm Length,
Bar Motion Ratio.

Bump?

 

[NorthloopCup]

Motion Ratio: Front: 1:1, Rear: 26:39 How did you figure this out for the rear motion ratio??? It's definitely not what I calculated it to be - 1.7:1 is what I got (off the top of my head)
Bar Outer Diameter: Front: 25mm
Bar Wall Thickness, N/A it's a solid bar
Bar Length,
Arm Length,
Bar Motion Ratio.

:S

39/26 = 1.5, so not that different to what you are saying mark.

Ah I see now! I got confused by the front being written as 1:1 and the rear as 26:39! Didn't make sense, but it does now! Flol

I found it measured at that, I was too lazy to work it out
