performance difference in Chrysler's TC by Maserati Posted December 22, 2008 Well.....if you really want to turn the TC into more of a fun to drive auto.....take out the lazyboys!!!!!! After taking the seats and motors out of my car I was shocked at the fact they weighed over 220lbs. The MOMO seats I replaced them with are 15lbs each. Also where your bottom sets is 10 inches lower than with the stock seats. Lets see---lower weight, lower center of gravity, equals weeeeeeee.
