I started a thread on S4 headlight covers a year or so back. A friend and I played around with blowing the shape in hot Lexan like a recumbant bicycle aerodynamic fairing. This scheme didn't work so we went off to work on the 2011 AROC convention.
One issue I never settled was what to do about the headlight rims. It doesn't seem practical to recess the S4 headlights like the earlier Spiders, so a bubble would have to stop short of the rim, overlap the rim, find a smaller diameter rim, or not use one at all. Have you considered this issue?.
I also have instructions from a BB member who made headlight bubbles to use on certain Ferrari models. PM me your email address, and I can send this to you.
bump bump- still looking. Conedriver: lots of problems to work out with this one. I have a parts car to experiment on. I was thinking of making new rims with the plastic attached, maybe paint them to match the car. Have even thought of removing the scoop from in front of the headlights from my parts car and making that part of the whole assembly. to be continued............
Don't know if this msg will find you after most of a year, but did you ever succeed in making headlight covers for your spider ? I have an 86 veloce that I cobbled some crappy Carello knockoffs onto, but not too successfully and they turned yellow and fell apart after 2 years. I wonder if those fancy 3D printers can make them out of good plastic ?
Just saw your post, missed it last month. Haven't done a thing yet but it is still on my mind. I'll put up a post when I get going on the project. Still looking for an unuseable pair of carello's on the cheap.
Hi Bob. I have a set of cloudy covers with one tab missing, and a slight crack by lower hole on one I'd be willing to send you if shipping is covered. (I'm in Kelowna, B.C., Canada).
Only thing is, I am about to leave on a out-of-country trip for 3 wks. (back Aug. 5) and don't have time to pack it up for you now.
Remind me when I get back, and I'll box up and get a shipping estimate for you, and then you can decide.
