I had all the bolt on upgrades and an eurocharged tune... evosport underdrive pulleys on our 3.2L are not worth the $$$.
I have not experienced Latemodel21 pulleys in person on a car yet, but dam they look good in a picture.
I was referring to the first question 180, which you left out of the quote...

Question 1, where can you get them - my garage, but don't they are not worth it...
Question 2 , is there lighter pulley systems - no comment...
