Default drag coefficient- What is it with the soft top compared to the hardtop?

What is the drag coefficient of the s2k with the soft top? How much better is it with the hardtop? Also has anyone done a top speed run on the same road with the same car at the same temp in the same underwear with the hardtop on and then with the softtop up? Just wondering if there is much difference and if so how much?

Real men do top speed tests with the top down!

Good questions. I have been wondering about that myself.

Also wondering how the Mugen hardtop compared to the stock one as far as drag coefficient is concern.

Here are some numbers (can't divulge the source):

Soft top up: .42
Soft top down: .51

Unfortunately I only have numbers on the hard tops in combination with the Mugen SS body kit:

Honda hard top w/ full Mugen SS kit (incl. wing): .391
Mugen hard top w/ full Mugen SS kit (incl. wing): .387

The numbers I got here are a bit different:
- soft-top UP = .38
- soft-top DOWN = .46

These numbers are frpm "Sports Auto" magazine.

ps. No hard-top numbers there.
