Been browsing E-Bay for suspenion kit options for my 156.
I have talked to the seller who states that the kit is 25% stiffer than standard. Also the manufacturer Inter Alloy is a reputable firm with some following on the continent but very little presence in the UK.
Stiffer suspension?? the suspension on my car is rock solid i was thinking about making mine a bit softer. The missus complains she cant wear her glasses due to the stiff ie cant keep glasses on. the shocks are bilsteins dont know if they are standard or not.
