  1. i wonder what spec mine is then. :rolleyes:

    it was advertised as a celica vvtli.... but it has leathers, e/sunroof and climate control, the alloy pedals, spoiler, 10 disc autochanger but no woofer all standard with the car.

    not sure on alloys as it had aftermarket alloys fitted. oh and no GHD,s lol

    Pop over here: http://www.toyota.co.uk/cgi-bin/toyota/bv/frame_start.jsp?id=Heritage_Celica_Brochures

    And take a look at the brochure dated a little before the age of your car ... should find it there. Though from the sounds of it yours is a Celica 190 :)

  2. GHD - fancy hairdressing stuff ;)

    As to the Style and Premium packs (technically models if you look at Toyota's brochures!), they're basically:

    Premium = climate control, tilt/slide sunroof, full leather

    Style = 17" alloys, spoiler, aluminium effect pedals, enhanced sound system with woofer, manual aircon

  3. If the car is going at a set speed, yes, bigger wheel = slower axle speed.

    But the car's speed isn't externally controlled, it's a function of the engine and gearbox making the axles turn through lots of revolutions per minute.

    Boring maths time->

    Using http://www.etyres.co.uk/tyre-size-calculator.htm - 195/65/15 tyres give a diameter of 643mm, multiply by 3.14 (approximation of pi) gives a circumference of 2019mm. So for every rotation of the axle, the car will move 2019mm forward.

    70 miles = 112 654 080 millimetres (=112.65km), so it takes 55797 revolutions of the wheel to go 70 miles, if you want to do that in 60 minutes (for 70mph) then that's 930 RPM near as dammit.

    So the speedo will be calibrated, more or less, to read at 70mph when it's doing 930RPM at the axle.

    Now, let's imagine we whack on some 17" rims, and go to 195/55/17s. These are 646mm diameter, so about 2028mm circumference. So at 930RPM, we go 1886040mm in a minute, or 113 162 400mm in an hour... 113.16km.

    Speedo will read the same, as the axles are going at the same number of RPM, but the actual distance travelled in a set time is further - so a higher actual vehicle speed (albeit we're still only dealing with very small percentages, and given that a speedo can be 10% out and still OK...)

  4. it would give you a slower speedo reading ,wheel would be turning slower due to it being larger..

    If we moved the car at a set speed, say 30mph as measured by GPS, then yes, with larger wheels the speedo would under-read by more.

    But as Bill T says - the speed's factoring off the number of revolutions of the axle, and for a given number of revolutions of the axle, the bigger the wheel the faster the speed.

  5. Goodyear now make their own aero flats and sold through Costco. All lengths individually available. Very high quality with metal fixings. At £6 + VAT this is very hard to beat and they are the best I've used. I've now fitted them onto all the family cars.

    Git, did they have 26" ones at your Costco? At the one in Edinburgh there were tons of all sizes, but stopping at 24" - wasn't even like there was a space where they'd sold out of them!
  6. I'd try grabbing ImgBurn (it's free), and use that to record your image file directly to disc. Sounds as though you might have been burning the image as a file onto a disc with Nero... whereas really it's a special sort of file that contains an image of several files and how they are to be laid out on the disc that needs to be recorded as an image rather than a file, if you get what I mean!

  7. PC Copper featured in kids' TV programme "Bod" when I was younger (i.e. 17th Century sometime), hence the catch-all term for Officers of The Law for folks of my age.

    I fear you may have fallen for a bit of a myth, the word's far older than the TV programme...

    From http://www.straightdope.com/columns/read/2209/why-are-the-police-called-cops-pigs-or-the-fuzz

    Let's start with cop. Cop the noun is almost certainly a shortening of copper, which in turn derives from cop the verb. The London police were called bobbies, after Sir Robert Peel who advocated the creation of the Metropolitan Police Force in 1828. Copper as slang for policeman is first found in print in 1846, according to the Oxford English Dictionary. The most likely explanation is that it comes from the verb "to cop" meaning to seize, capture, or snatch, dating from just over a century earlier (1704).

    The derivation of the verb is unclear. Most authorities trace it to the French caper and before that to the Latin capere, to seize, take. Other English words derived from capere include capture. Thus, a copper is one who seizes. An alternative theory is that to cop comes from the Dutch kapen, meaning to take or to steal.

    The word "cop" has other meanings as well, all connected to "catch" or "snatch":

    To "cop out" meaning to withdraw or escape, or to evade responsibility

    To "cop it" meaning to be punished or get caught

    To "cop a plea" is to try to catch a lesser punishment by admitting to a lesser crime

    "A fair cop" means to be caught in the act.

    As with many words, there are several stories floating around positing various origins, almost certainly false. The notion that cop is an acronym for "Constable On Patrol" is nonsense. Similarly, the word did not arise because police uniforms in New York (or London or wherever) had copper buttons, copper badges, or anything of the sort.
