where can we get the progress springs and how much? the sprint ones are like $135 shipped on ebay.linenoyz said:The Progress springs went in without any problems at all. No modifications, no headaches. Piece of cake. They are stiffer than stock, and it's a very comfortable ride. It's just about perfect, in my opinion.
One thing to never lose sight of, WOT is subjective at most with this car. You can have the pedal mashed to the floor and if the ECU says back off, it does. This is a MAJOR reason that "drive by wire" sucks.linenoyz said:I don't believe the car was at WOT at the very start of the run.
Why are progress better than sprint springs?Tom01SC2 said:Sorry to go off on topic. I heard those Progress springs dropped in without any modifications, is that true? Do you feel they are stiffer than stock? I like progress more than sprints, so I was thinking about going that route. However, I don't want to mess up the handling by switch to a weaker spring...
That was using a wideband O2 reader out of the tailpipe. It's pretty accurate.DanM said:I wouldn't trust those A/F readings 100% either.
I saw your video, and they were using a tailpipe sniffer for the dyno, right? Those are never all that accurate. If you want 100% accuracy, they need to be using a wideband.
