  1. Read this months TopGear mag, it has a really interesting bit on aero.

    Crazy stuff like the new Civic Deisel took 2g/km off its emissions by putting two tiny plastic wedges between lights and wheel arches.

    They said most oem splitters are designed to keep air away from engine bay to reduce drag and increase economy.

    It is amazing how much a tiny change can make, there was a guy whose blog I read who was trying to make those wheel well deflectors for his car, you know the ones that some cars have fitted in front of wheels? Well he made them in a way that seemed sensible. He placed them in front of the tyre, angled from front to back. Result? Reduced economy and increased lift :(

    The TopGear article concludes aero is a dark art only understood by Adrain Newey. Lol.

  2. When I bought my car I was advised the brakes were seizing, the car was only doing 3k a year at the time. Got new discs and pads, garage said they'd put copper grease in one caliper as a bit stiff.

    They said they couldn't see them seizing. After a drive and red hot brakes took it back to them and they said couldn't see anything wrong. Try an MOT garage that had brake rollers. Suggested replacing brake master cylinder.

    Well the MOT was due so put it in, mentioned the brakes, and it sailed through :-/

    So the current situation is that if the car sits a few days then when I'm driving I get a bit of vibration through the steering wheel and the brake pedal goes rock hard. But then it eases off again.

    Where would you start trouble shooting this?

    Sadly for me new calipers or new brake master ain't gonna be cheap or easy.

  3. Forgive me if I'm wrong but I assume most people fit them for aesthetics not for aero?

    Its unlikely that fitting a bit of plastic or rubber with self tappers will give you kilos of downforce, and is more likely to make things worse than better if it isn't specifically designed for the vehicle. Proper aero designers can make huge differences with minute changes, the splitter would need to work in harmony with the engine tray etc.

  4. My 1.4 75hp is getting an actual average 45mpg since I bought it. That was with 2 tyres leaking at the rim, only fixed on Tuesday, and randomly binding bakes, not fixed yet, and a pretty full boot. As mine is an SE I'm also dragging the weight of electric windows, electric sunroof and rear popouts around. Also I have a recon gearbox and 70 is about 3400rpm in 5th. 4th and 5th are pretty close with only a few hundred revs difference at 60.

    At current prices I'm getting 300miles to £40 roughly and tax is £160 a year.

  5. I pushed up on the edge of mine and it twisted 90 degrees and then I could just pull it straight out.

    Though admittedly they'd been out before, when the car was new Arnold Clark had to repair it cos they dropped the transporter's upper deck on it :-o

  6. Looks like you need to recalculate the normals on the side glass, or at least join the vertices.

    What application were you using? In 3dsmax I think you could sort it by making sure they are all part of the same smoothing group? But I haven't used it since version 5, many years ago...
