prayers1 153 Report post Posted June 26, 2022 Installed the new 3rd member and I really don’t feel much difference on take off from the 4:11s. It isn’t as sluggish as I thought but I still haven’t put it to its true test by doing a hard pull out because I have to drive 500 miles to break it in. on the highway I am down about 500 rpms. Sorry forgot to write down (mph at what rpm). The car surly drives smoother but that also must account for the QA1 rear single adjustable shocks. Not as much hovering in the rear. I still have a slight drone noise. I’m gonna replace the flowmasters & 2 1/4” exhaust with 2 1/2” with Borla mufflers and cut outs. 1 RPM reacted to this Quote Share this post Link to post Share on other sites
