    Fernando Alonso has won the Le Mans 24 Hours for the second consecutive year alongside Toyota team-mates Sebastien Buemi and Kazuki Nakajima.
    The Spanish double Formula 1 world champion's number eight car crew, who took the lead with an hour to go, were also crowned world endurance champions.
    Alonso, 37, shared the car with fellow former F1 drivers Buemi and Nakajima.
    It was a one-two for Toyota with their number seven TS050 hybrid, featuring Britain's Mike Conway, in second place.
    The number seven car, also crewed by Kamui Kobayashi and Jose Maria Lopez, led for much of the race before two late punctures.
    "I think car seven was quicker than us for 24 hours, they really deserved the victory but today the luck decided that we have to take the trophy," Alonso told Eurosport.
    "Luck sometimes plays an important part in motorsport and today we feel extremely lucky and maybe we don't deserve it but we take it."
    The number eight car crossed the line 17 seconds clear of the pole-sitting seven car after 385 laps of the 8.467-mile circuit.
    Stoffel Vandoorne - Alonso's former McLaren F1 team-mate - was part of the third-placed team in the number 11 SMP Racing BR Engineering car.
    Before last year, Toyota had never won the sportscar race despite years of trying.
    Alonso has been chasing motorsport's 'triple crown' of victories at Le Mans, the Monaco Grand Prix and the Indianapolis 500.
    Twice a Monaco Grand Prix winner, he failed to qualify for this year's Indy 500 and the American classic remains the only victory to elude him.
    Only Englishman Graham Hill has won all three classic races in the history of motorsport.
    Alonso has said he will leave the the World Endurance Championship after the end of the season.
    He tested a Dakar Rally-winning Toyota Hilux in March and has been linked with an attempt at the iconic desert-based endurance event in 2020.

    Wheel alignment the old school way...

    I paid a lot of money for the last alignment and not happy having measured it myself and seen the set up. 4mm of toe out per side at the rear! I've reset it to 2mm per side, now onto the fronts.

    How and where did you actually measure the toe (given that the string line in the picture is not through the axle centre line)?

    I use a long steel ruler standing upright on the edge where the sidewall meets the "tread" rubber. Very pronounced edge on an Avon cross ply tyre. Measure from the ruler to the string.

    So the toe was measured at axle height at wheel rim diameter - not on at an arbitrary tyre diameter?

    I'm sure he does, but the setup (as pictured) might lead someone to think he doesn't.

    Jut wanted to clarify the methodology.:)

    Surely the rear has toe in, or at least parallel? Is there roll toe change?

    That's an interesting point, Pat. The thing has a lot of power so it will tend to induce toe-in under load, but I would have thought it would be near undriveable with 8mm of total toe-out at the rear. That should give enough "lift off " oversteer for a whole grid of rear-engined Porsches.

    Especially being green, it would be difficult to find out in the scenery!:)

    But stand out against the tyre wall... :D
    On a non aero car, you can design a bit of squat toe out to compensate for the toe in forces under acceleration, and then toe in on droop to give stability under brakes, but I wouldn't like toe out at 200mph

    Thanks for your concern and valuable advice guys, but I have been doing this for a while, including string alignments.

    Rear (and front) toe-out is the recommended setting for my car in street course trim. How much you run is a function of the types of corners at a given circuit and how you want the car to behave at the different phases of a corner. I like the car to "rotate" under throttle at the apex. I used to run front toe-in to make the car easier to drive on the straight at high speed but I'm quite OK now with less stability but better turn-in of toe-out.
