After Rebuilding The Front & Rear Suspensions (bushings, ball joints, etc. etc. - yet keeping the stock springs) On My 73 Spider The Ride Height Was Entirely Too High, (you could easily put your fist between the top of the tire and the fender well) US Federal Mandated Height? I Didn't Want To Alter The Ride Quality (not excessively anyway) So Decided To Go With Eibach Springs From Classic Alfa. There Literature States That The Springs Will Lower The Car Approximately 40mm And Are Slightly Stiffer. That's Probably Lower Than I Wanted But Was Prepared To Shim The Springs If Necessary. After Installation The Measured Ride Height Was Reduced 1". The Car Now Has The Stance Of A Euro Spec Car (not too low in my estimation) And Is Only Slightly Stiffer. I Would Recommend The Eibach Springs For A Standard/Non-Modified Car.I was also curious about this. Can you run the Eibach springs front and back with everything else standard?
Maybe just upgrade to Red Koni shocks.
