The shocks for the rear of an EU4 car are different specifications (as detailed by Shock Factory) to EU3 even on the original MMC EU4 Spax fitment.
If you have an m3w still at Eu4 ride height then different rear shocks are needed - Ohlins are also able to supply a different rear shock absorber.
Rare to find EU4 ride height m3w's in UK but quite common to find them in EU. Out of 8 x m3w's here in workshop currently, 3 are at EU4 ride height.
