What about a rear bumper cut out?

I don't think so, but so much matters on very small design features. Read these threads on rear diffusers to see the subtle changes at play.

You don't want air to pass through your rear bumper, but around it. Build a belly pan to prevent the rear bumper from acting as a parachute, like this:



Air passing through a cutout or "speed holes" creates a lot of turbulence, which creates drag.

Thanks for the info. I'll look into it. But perhaps I should start from simpler things like grille blocks and air-dams. I've got my number plate grille block done today. Maybe I'll show it to you soon.

So someone scratched my car. Seems purposely scratched witha a key or a nail or something. Should I think of getting an alarm? Would it help at all? Or am I just a bystander in this situation?

And it's time for the pics. These were taken before the scratch though you wouldn't see it here anyway.

Looks a lot like my black 1998 Civic coupe. Someone hit it with their door a few months ago in a parking lot. I was bummed. But the car is OLD, and it is a grizzled warrior. Another scratch is a distinction line. (And it ain't worth a dime anyway.)

I guess you gotta have a kind of rat-style attitude if you don't wanna go mad. I think I'm developing it. It's more about how functional your car is than how pretty it looks. We've resprayed part of the car but the seams show. I think I might respray the whole car in the future but that's not anytime soon.

I haven't updated this in a while and just so it doesn't get completely forgotten - a little update.

I've been doing some weight reduction. Mostly interior parts. What I like about it is the reduced rattles. Of course it introduces more road, wheel, and exhaust noise. But I like the trade-off. Especially the exhaust noise as I have no stereo to listen to. I feel more in tune with the car. One of these days I'll get to showing you the interior.

So according to my calculations I get 6.557971 l/100km. Which is good in my book because the last owner got ~8 l/100km. Hope to improve this modest figure further!

Yes, you can absolutely get it under 5L/100km, and under 4L is not out of reach at all. I am down to about 3.8L/100km nearly all the time, ajd have gotten as low as 3.35L ... or about 70mpg (US).

Let's see more pictures!
