and therein lies the trick. sure, you could pick out someone else's spring rate setup, but how would you know the correct length ? you would also be "taking away" money from a valued Alfa community retailer who spent the time and effort to come up with that setup.you could just order Eibachs xxxx rate spring in the right diameter and length and you have the same spring, probably at a lower cost.
of course, you would really need to try the original established setup first, to know what you want to change . . .In addition, if you want to try something slightly different, you can give it a try.
