  1. If you don't do step 3, then you will not properly hone the cylinders round as you will not go through the entire heat range. This is the most important step other than warming up the engine. You must create as much pressure and heat in the cylynders during break in.

    That is contrary to porsche recommendation.

    I think it is more important to run the engine "gently" for the first 1000 miles, then start the higher level break in.

    To each there own.

  2. Proper breakin must be done in the first 100 -200 miles and below is the proper procedure:

    1. Always bring engine to FULL operating temperature before high revs.

    2. Drive trhe car easy for the first 10 miles or so, varying the rpm's from 2,000 - 5,000.

    3. Then, start bringing the engine up to maximum rpm's and letting the the engine bring the revs back down by coating in gear.

    4. Repeat several times, in order to create maximum heat in the cylinders.

    5. Drive around at lower RMP's for seveal more miles, remembering to vary the speed of the engine every couple of miles.

    6. Repeat number 3, 4 and 5.

    7. Park car and let the engine cool down overnight.

    8. Repeat all the above 2 more times.

    Your engine is now fully broken in correctly and should be driven hard from here on.

    While I do not have a problem with the above, I think that you should do this for more than 3 cycles. Minimally a 1000 miles, 2000 is better, frustrating as it may be. Also I would keep revs below 4200 and when you do start redlining the car do not sustain redline, redline the motor, then back off for a few minutes, repeat. Do the redline cycle for a couple of hundred miles.

    Step 5 is really important. Do not go for a 200 mile cruise on the interstate when the motor is new and put the cruise control on. Every five minutes or so shift to another gear.

  3. Due to the smaller overall diameter (compared to a 225/40) you may actually gain some clearance at full steering lock. The other potential rubbing points are the plastic air deflectors for the brakes and the clutch tubing in the driver's side wheel well.

    Clearance increase/decrease due to camber is difficult to determine statically as the tire deforms under turning loads. You have to test to see what happens. If it rubs under no load -> bad, If it does not rub but is close you will need to test under load to see if there is a problem.

  4. Another thing I noticed yesterday was that there is an added on protuberance where the upper part of the inside of the rear of the door meets the body. It is a triangular shaped piece (see picture) that matches up with a notch inside the door. I do not know if it has something to do with enhancing rigidity or has to do with side impact protection (helps keep the door in place during impact). Maybe something else. Ideas anyone?

  5. So just got back from the dealer.

    1) the car looks pretty good in the flesh

    2) One car I looked at had bridgestone RE050 tires on it. It will be interesting to see peoples feedback on this tire as it is new (at least to me). It is listed as a max performance summer tire on tirerack and it only has a treadwear rating of 140.

    3) The rear panel in front of the rear wheel now has clear plastic film on it.

    4) The stock 17" wheels have gotten tiny, 6.5 and 8 with 205/235 tires

    5) The rear rotor has increased in size. It is actually larger than the front rotor (298 front, 299 rear). Seems bizarre to me

    6) There are no handholds on the doors anymore. Just little pull slots to close the door with.

    7) The ignition key hole is at a weird angle, angles in towards the steering column

    8) The window switches are on the doors

    9) The new cupholders are pretty gimmicky. I think that if you bust one the whole dash may have to come apart.

    10) There is a 12volt outlet in the passenger foot well

    11) The rear bumperettes are body colored

    12) The adjustment levers on the seats are painted

    13) All kinds of plastic covers in the front trunk

    14) The console between the seats just has the ashtray, cigarette lighter and now the top opening switch (at least I think that is what it was).

    I have pics if anyone wants to see anything in particular.

  6. If you are standing in front of the car and looking at the battery it is the right hand one (driver's side).

    You can always tell the negative lead by:

    1) it usually goes straight to the body of the car

    2) there is a negative (-) sign next to it on the battery

    3) the positive side is usually covered with a plastic/rubber boot that has to be removed in order to get to the retaining screw.
