RE: Fury and Lotus Elan questions.

Dermot,

If you are interested, I can send a picture of the front air dam fabricated
installed on my Birkin/Hayabusa.  It is located behind where your hinged
front body shell would end.  In fact, it is bolted to the front member of my
skid plate.  So it is not a chin spoiler.

It is made of 1/2-inch thick industrial rubber conveyor belting and trails
to the rear at a 45° angle.  I wanted something flexible for when I run over
the occasional curb.  I trimmed the lower edge to clear the track at my best
estimate of the ride height and body roll with the suspension compressed.
The rubber was trimmed to perfection by the abrasion of the asphalt  track.

Because of variables like wind and other factors, it is hard to say the
exact difference it made at top speed, but I would say somewhere in the 2 or
3 mph range.  I would say that it definitely creates a low pressure area
under the car.

As for the loose rearend, the fellow suggesting the lower front and higher
rear ride heights is right.  Mine is about 1.5 inches higher in the rear
with the front at 3.75 inches, (as low as I dare.)  I also have a rear
diffuser which probably helps the high speed stability and possibly the
cornering.

  Hello all,
  I have a Fury/Busa and it gets very light at the front at high speed. I
cannot do a chin spoiler due to the flip front and I am thinking of vanes or
winglets on either side of the bonnet in front of the wheels. I have seen
them on other Fury and Phoenix models. What angle should they be and can
anyone send me photos or suggestions to plant the front better?

  Does anyone have a BEC Lotus Elan S2 or links to details of one?

  Cheers.

  Dermot.
