  1. It has the usual scratches and I want to go body colour - basalt.  I've bought a new gaiter and handbrake cover to match the steering wheel - i.e. black with red stitching. I also got to fancying a wooden gear knob 917 style. They go for around £50 -£80 but then you have to get an adapter because of the inexplicably complex way the ball fits onto the shifter. This goes another £120. 

    I don't need to buy another shifter because this car shifts sweetly and easily. I've had the idea that I can take the shifter rod out, hasksaw a few inches off it and weld a threaded portion to it. I can then screw the ball straght on and it will sit lower than before which is fine by me and I'll be £120 up.

    Tell me why this is a stupid idea.

    Happy

    Picked car up from paint shop, bonnet back to bare metal, front bumper and wings, extremely pleased!!

    Really need to get mine done..... BTW have you blacked your vents? And if so did you DIY it?

  3. Top tip - get under there and slather everything that might move in grease. Take a look and everything will look dry and covered in surface rust. It's supposed to be a service item but no-one ever bothers.

  4. I've never understood why a 6 speed manual 2.7 is high VED and a 5 speed is low. And I probably never will. Actually I think I read somewhere that cars emit a burst on emissiony stuff on gear changes so if you have more gears you have more gear changes. 

  5. I polybushed everything possible on my Subaru. The ride suffered but it was on coilovers anyway so it wasn't great in the first place.  On the positive side it just felt totally composed however hard you pushed it and they tyres wore absolutely evenly from side to side - not something Subarus are known for. I guess everything was staying in alignment better without the flex. That said I don't feel that the Boxster has a huge amount of slop in the first place.

    You know that Spyder performance sells polybushed arms of the shelf?

  6. Just keep what you've got and get a DSC sport controller. You won't believe what it does and you can easily tune just about every aspect of the car's handling a with laptop. It does real time data logging too.  You'll have a more comfortable road car that will become a track monster at the touch of a button.

    Lot of money new but they do come up used from time to time. I got mine on 911.com for less than half price. And a nice member on here sold me a cheap accelerometer which you need with .1 cars.

    The engine bay is not a sealed chamber so air can come in through the side vents when conditions allow and be vented under the car and can blown out by the fan or sucked out by the dynamic air flow in the right conditions.  If you add the covers you will limit the dynamic airflow extracting hot air, but the ram effect will be forcing more cool air (along with more aerodynamic drag on the car) into the engine bay to vent underneath.  You will also gain a little ram air effect into the induction intake on the left side, however when stationary or slow moving the engine bay fan will still be able to blow hot air out through the vent even with the scoop fitted.  Fitting the covers just forces the airflow to work in a different way but still ultimately achieve much the same effect on cooling and a possible very small plus on the engine air intake.  If it didn't the GT4 would be in trouble with high engine bay temps...

    Ultimately your car, your choice.

    If the car's going along and the fan is going could the resultant turbulence damage the IMS?

    The N/S one is the air intake, the O/S one is there as the airflow going past it will help draw hot air out the engine bay whilst on the move. They both serve a purpose

    You can't have it both ways - it can't push air in one side and suck it out of the other.

    I think the drivers side one is a vent that the fan blows hot air out of.

    A LHD car would be better because your ear would hear the intake better. Can't believe Porsche didn't alter the whole design for RHD cars. Cheapskates.

  9. What we need is someone to test the air pressure on a stock car, test a stock car without the baffle, put the baffle back and test with the scoops and then test with the scoops and no baffle. Or the other way round for the last two. Then once we realise they make no difference take some good pictures so I can decide whether they look cool enough for me to bother.

    Caymen have the vertical strakes not horizontal.  But I also recall that some have fitted Cayman grills to their Boxsters. Absolutely no idea of the (measurable) effect on airflow - if any.

    I read a thing somewhere where a guy was an engineer with flow test capability so he tested them and found a very small increase in pressure at 70mph. He then did the same test on a standard car and found negative pressure at the same speed.  I'm sure Porsche know what they're doing though...
