I made a one-piece polycarbonate plastic windscreen / wind deflector for the 987. I modeled it after those made by "Zefferus".
They sell windscreens for the BMW Z3 / Z4's, but not for the Boxster.
Total cost for the plastic windscreen and velcro straps was less than $25.00. That's a mere $475.00 savings over the Porsche OEM windscreen
Polycarbonate is the material used in Lexan or Makrolon. Polycarb is much stronger than acrylic / plexiglass, while being much easier to cut
using only a jigsaw and inexpensive blades. The link below illustrates the durabilty difference between the two plastics.

By using PVC / Velcro straps to secure the windscreen, no drilling is required. Attachment or removal take about a minute.
I had it out for a test ride earlier today in 28F (-2C) temps and the difference in wind protection, warmth, and noise vs no windscreen was amazing.
Simple is as simple does

The 6 Attachment straps ( 12" X 1.5" ) are made of 18oz. PVC with sewn 2" velcro ends. They tighten around the safety bars via narrow slots cut into the windscreen.
The 12" tall X 1/4" thick windcreen as seen from inside. The windscreen rests atop the subwoofer enclosure.
The safety bars outline is traced with a Sharpie onto the 52" X 12" X 1/4" "Makrolon" Polycarb prior to cutting.
A jigsaw with a metal cutting blade is used to cut the safety bars outline, and a 3/16" drill bit and wood cutting blade are used for the 6 strap slots ( not yet marked).
Paper backing on both sides is left on to prevent scratches while cutting the outline and strap slots.
Winterize the Porsche ? .... Never !
A 70lb sandbag and shovel are in the trunk ... just in case.
Slap on a Porsche decal ... and the twisties await !
