Oh I see, so the water might come in by the antenna, slide down the cable and make its way into the trunk... Real sneaky Mission impossible s*#t.

I'll definitely make sure to check the antenna too then. Can you show me what an antenna key is? Google seems to point me all over the place when I search for that term.

 

You can get them at an auto parts store but it is just a socket or hand tool with nibs to fit into these grooves to unscrew.

As well the clocking of the base should point directly at the emblem on your steering wheel




Hope that helps buddy if it makes no sense you'll see what I mean when you unscrew it it has grooves and can be clocked to "fit flush with the body"

 

Hey that's awesome, thanks for the pics! Will have a look over the weekend and report back.

P.s. love the yellow

 

So I had trunk leaks on both my s2000s. My first caused the trunk to rust but the leak was simple to fix. It had a newer OEM top that was installed well when I bought it. I got new tail light seals and sealed up the bumper vent to fix the leak completely. On my second car, I could tell the top was an aftermarket that was not installed particularly well. After sealing the bumper vent and checking the drains, I was out of my own ideas. I found an installer on this board, who lived about 2 hours away and had done many installs. I figured I was best to have someone who knew what they were looking at to take a look. He opened everything up and found that the trim piece around the back of the soft top had been damaged during install. I had to go home, unfixed, order the part, and go back to have him fix it. Part number listed below. I'm not saying this is your problem but it could be. I'm not sure what to tell you to look for. If you can find someone local who has done 100s of installs, they are a super valuable resource. Mine has not leaked a drop since. It's not cheap and shipping is a PITA due to size and not wanting to damage it.

Al-right, I finally got around to check it out. So I unscrewed the antenna and there were definitely traces of water coming through, see picture. So I cleaned it and sealed it with silicone.



However, this entry point is definitely too small to explain the massive inflow of water. So I checked the drains at the side of the top again, this time by feeling for the exit point in front of the rear wheel and lo and behold, it felt like it's completely shut (even though some water does come out when I pour it down the side of the top.

Sooo, since I'm putting on new wheels soon anyway, I'll clean out these drains while the wheel is off. I'll post my results after the next rainfall.

EDIT: It would seem that it was the drain after all. When the car was on the lift, I was able to scrape out most of the large amount of dirt that had been sitting in the drain and gotten extremely hard over the years. Driving through heavy rains yet again on the weekend (not sure why we're calling this "summer", but anyways), the trunk remained absolutely bone dry

 

Hey everyone

Here's an update after a long while, for anyone who has the same issue: As it turned out, none of the solutions above fixed the problem after all. Water could still get in.

So after quite a while of ignoring the issue and staying out of the rain as well as possible, I recently noticed a tiny tear in the roof, right were it connects to the door area on the right side of the car. My garage fixed this with what's basically a round band-aid on both sides of the car, see pictures. A few days ago, it was parked in monsoon rains yet again for a whole day and so far, no more water could get in. I feel like this could be it.
