      Well if anything, I learned that I should really install the OEM spoiler sitting in my garage on my Lexus SC

      Thanks for the link

      Plan on hitting 140MPH in 40MPH zone?

      I guess in the first generation TT, the addition of that lip spoiler did end up helping for high speeds. I do remember reading about the non spoilermodels having issues

      All of my cars have spoilers, and wings.
      Stretched, poke, rubbed......sounds like a porn stars butt hole.

      Funny you should mention that. The PO said that he had it 'up to 140 once' and said it was rock solid. I was a bit unsettled

      He was older, though, and had his share of impeccably maintained sports cars and belonged to the local Lotus club I was in, so I trusted that it was done with some forethought. I'm not sure where the 40MPH bit comes from, is it some TCL meme reference that I missed?

      Personally I think it looks better, and if someone questions my tastes I can cite my sources now

      Interesting read. May take me a while to grasp the idea that a lip spoiler causes less drag than no spoiler, but I guess in the meanwhile I can hope my tiny wing/spoiler(?) on my mkIII glx is doing some good.

      It is a meme now There is a thread on the Charger crash - guy was doing 140 in 40 zone and survived. Darwin let TCL down. Another point is that, from the article, spoilers make a difference, if any, at very high speeds (100mph), how often do you get your Lexus up there?

      The spoiler did very little. The biggest changes came from the extensive suspension changes.

      A couple things that the article doesn't really take into account. SMALL aero deviced don't work until you're going fast, true, But, like a Piper Cub can FLY at 25 mph, LARGER aero devices work at lower speeds. In fact, the lower the speed you need the device to work at, the larger it needs to be in relation to the mass it's working on.

      So...

      All those ricers with big wings aren't putting those big wings on because they are going fast, but because they are going slow.

      To be serious for a moment, drive at 60 mph, and put your hand out the window like a wing and angle it up or down. Feel what the wind does to push it around? That's only a few square inches at a fairly low speed. Aero devices are working at this speed in much the same manner, and why they still work on street cars.
      I love cars, but the problem is they are like schroedinger's hobby. They're always in a quantum superstate of being both awesome and a huge waste of time and money... until observation momentarily forces them into one state or another.

      40mph is the rough speed at which aeros overcome rolling frictions.

      If the cd lowers from .33 to .32, it lowers regardless of speed.
      A list of mods, all cars ever owned and something cribbed from a book, song and/or movie were all just here. Sorry you missed out on my unique, snowflake-like individuality.

      I like that graphic showing the E36 with and without lip.

      I've been strongly considering buying this lip...it just seems so functional

      Didn't it also have something to do with the design of the control arms? I thought Clarkson said something like that when he tested it.
