Boy I sure wish I could start paying attention to mods for my car. Well, if when I get the basics taken care of (like getting the car past inspection) I'll know where to go to start work on the underbelly pan and other aero mods.
basjoos - I have noticed that road noise is diminished. Hasn't been long enough to notice if the engine bay stays cleaner, but I'd have to agree that it would since the dirt really has no place to get into the engine bay now except through the radiator opening.
1993CivicVX - The time for your mods shall come soon enough, lol, and thanks.
Nerds Laugh At Me - It's a mild steel exhaust system that I coated with High Temp aluminum content paint, so basically it's a crude form of aluminized steel. I do have a slight rattle where the flashing contacts the exhaust near the 90 bend. I am going to stuff a chunk of fiberglass in between the tube and flashing to stop it. It only rattles at startup and once in a great while at idle. I'm also thinking that I have a great template now to make an all aluminum underpan. but that isn't going to happen unless I come across a 6'x'10 sheet in the garbage, lol.
I just went from a 92 CX to a 95 DX (hatch) that is setup more as a trackday car. It's my beater, since I have a 99 Si for auto-x/trackdays.
Anyway, I just lost about 10mpg in the changeover. I've been a bit of a hypermiler in that I was able to wring a best of 49.x mpg out of my CX (1.5" drop, skinny tires, VX diffuser, Akimoto cone filter).
The new one has a d16z6 swap, DC 4/2/1 header, stainless 2.25" b-pipe, stock axleback exhaust and Ground Control/Koni yellow suspension.
I just added a VX diffuser to the rear end.
I was surprised to see how much of an effect lowering the front end has. At the moment, the front is higher than the rear (former ownder had it jacked up for winter use) Since my suspension is adjustable, I'm going to drop the front an inch for a total of a 1.5" drop.
My question (after all this) is that I have a nice urethane lower lip for the front spoiler that I haven't installed (don't know if I want to attract more attention to the car). Do they actually do something to improve aero (in terms of efficiency) or does it add drag??
The VX in stock form has the Front Urethane lip. If it's the stock lip then yes, go for it. But lowering the car dos more than just having the lip. If it's an aftermarket lip, what kind is it as some of those lips will add more downforce and drag than the OEM VX lip will.
