Picked mine up Wednesday, so much smoother than my 22 or 23 STs, had back to back carbonized gray ones, so it was time for a color change , so I went with the metallic white, which pops , so far, the tranny is nice and smooth, going to put a few miles on it before I put some stuff on it, but HR springs new have been in my garage just waiting and I want to do the roof rail delete too, but it's fast enough for me stock.
