Ferrari 360/430 Spider Wind Stop Gaskets

The "wind stops" (metal frame, gasket, and thin screen) in the Ferrari 360/430 Spiders reduce the wind whipping in the cockpit of the car and add a nice distinctive touch. On some Spiders, the gaskets in the wind stops have deteriorated to the point of failure. This is rather unusual to see and I suspect that it's due to either some sort of detrimental treatment product being used (such as Armor All) to clean and shine them, or a material failure in some batches.

I've made a number of sets of these gaskets as a learning experience and am offering them for sale. Some sets are better than others as I was learning how to make them. The defects are small bubbles and inclusions. If you need perfect, then please, buy the OEM frames. 

The better sets are being sold first.

Price per set: $300 plus shipping. Each set includes the three gaskets and three sheets of screening material. If interested, please contact me at: jcoryat@usnaviguide.com

Installing the gasket in the frame is a bit of a trick. The screening fabric is very fine and drapes very easily. To get the screen to line up and be tight and wrinkle free takes a little effort.

1. Place the frame on a clean table.

2. Drape the screen material over the frame.

3. Stretch the screen material enough so that the wrinkles and sags in the material are gone. Tape the edges as shown in the picture.


4. Fit the gasket over the screen material so that it aligns with the frame.

5. Starting in the corners, press the gasket into the frame. Press it in enough to grab but not all the way in yet. 

6. Work around the edges pressing the gasket in deeper until it's nearly in all the way. It will look lumpy at this point. That's ok.

7. Remove the tape. It should look like this.


8. Flip the fabric over the top of the gasket so that the fabric can be cut under the gasket to free it from the frame. Use a VERY sharp snap blade knife and gently fit the blade to the tab of the gasket and trim off the fabric. It should cut easily. Be careful not to cut into the gasket. That would be bad. The gasket is pretty tough though.

9. Use a clamp with a rubber tip (like pictured) or similar to squeeze the last bit of gasket into the frame. It can take a lot of force to get the gasket all the way in. Some sort of mechanical help is going to be required. I found using a bar and a couple of clamps worked well for the center wind stop but the roll bar wind stops are rounded so I used a single clamp on the back of the frame against the table to squeeze the gasket in on those units.


10. Examine your work! If done right, it should look like this. The gasket should be tightly against the frame.


11. Finished product.


Potential problems

If the screen stretched too tight, the fabric will probably tear, or the gasket won't be set all the way in. If it's too loose, it will likely have wrinkles or sags. The fabric, stretched properly, will be tight as a drum, which is how the OEM screen is set.

Once the gasket is set, it's probably set for life. Removing the gasket will damage it noticeably. So it's super important to get it right the first time.  

Update: Supply exhausted. Sale ended. Thanks.

    One question, one comment...

    Q: where did you purchase the replacement screen material?

    C: I am using screen cording to replace the rubber gasket. It actually looks pretty decent and can easily be replaced if I have another screen failure. Just a tip for other readers.

Bosch Throttle Body (Holder) Woes

My 360 started going into limp mode a while back. It was subtle at first, with it starting to lose power after 4,000 RPM's and then less subtle when it would barely go above idle. Limp mode protects the car when some vital part has malfunctioned. I know a master Ferrari tech that is nice enough to answer questions for me about the car. He lives more than five hundred miles away and it's like telemedicine.  The codes indicated a problem in the drive-by-wire circuit, likely culprit: One or more TB's or the accelerator potentiometer (AP), which is the foot pedal sensor.  I had a good code reader that could monitor the AP voltages (2) and they appeared to be within specification. That left the TB's, one or both. After a long discussion with the tech, his answer was to replace the throttle bodies (TB). The Ferrari 360 has two TB's. One for each bank of four cylinders. To the Ferrari mentality, replacement could only be with two new TB's: "Ferrari likes replacing...

Capote Elastic Bands Replacement

Virtually every Ferrari 360 and 430 has failing elastic bands in the capote, or soft top. The only cars that don't have these items failed right now have had them replaced in the last five years. My car is no exception and my original 20 year old elastic bands are well past the time they should be replaced. The top has a number of elastic bands that help control how it folds up and how things move. These bands are the same type of material as appears in underwear and stretch pants. As these things age, they wear out. So just like your old underwear, the elastic on the 360/430 top loses it's stretch. One of the things these elastic bands do is control a bar that shapes the headliner and roof line. This bar has to be pulled back and lie flat so the rest of the machinery that constitutes the top can fit into the tiny little space in the back of the car. When the elastic bands give out, the bar doesn't move to the right spot and the frame can impact on that bar as the top folds...
