Advise on 930 suspension parts for 911
 

My question: is it worth the expense convert to the 930 rear trailing arms? and also up front with the inverted Bilstein's (inverted cartridge style) ? I have done some searching and reading on here and after several hours I'm still wondering if this would be the "correct" path to take... so any input would be appreciated especially from those who have gone with the 930 trailing arms. Thanks
