R26 springs

yeah..could be the aftermarket eibach springs for R26..they are softer..

renualt part number for genuine eibach front spring is...8200647852

 

https://www.ebay.co.uk/itm/New-GENU...h=item2f000f2241:g:HH0AAOSwAPVZJBZS:rk:2:pf:0

part number on these looks like it starts with the same numbers as yours..hard to see....but it says c/r instead of b/r as on yours..

 

What softer than the original non lowering R26 suspension?

 

yep..seen the spring rates somewhere on here.
