free/cheap beneficial to car eco mods actually worth doing

slow10,
I had used some spring compressors to lower the 2002 Q45. Made a slight improvement in mpg.

BUT i forgot to get alignment.....ate up tires.......arrrrggggggg!!!!!

I mean plastic. Audi has the ability to make them out aluminium and make the exhaust avoid the panels. Also Audi has never been known to make changing you oil or any work really easy on their cars.

Plenty of users have made bellypans out of plastic and have had zero problems.

Those panels are not aluminuum.
THey are thin plastic.
As a statement: car makers don't want metal flying of cars to cut up tires.
Do you know of one manufacturer using aluminuum?
(outside of a skidplate application)

yeah that avoiding the exhaust is tough........

here is my mpg Q45 album...plenty of instructional pics on how to avoid exhaust.

My Infiniti Q45 had a factory plastic underbelly pan. there was a little hinged door for changing the oil and filter. pretty dang convienient.

I would have left the panel there except the IMPUL body kit lowered the profile

Manufacturer belly pans I agree with due to the testing they do. Just don't agree with at home installed belly pans because if they cause fire or damage to other cars good luck with your insurance.

of most of the mods done....
mirror deletes, tails, etc....
the underbelly pan is the least dangerous....

how does my underbelly pan "cause fire or damage to other cars" ?

you statement lacks any cedibility.
All of the underpan threads discuss the heat issues.
1. Have you any factual basis for what you are saying?
2. have you even read the threads on underbelly pans?

Plastic melts way before it starts on fire (if it even does ignite, some don't). If you aren't comfortable doing the mod that is fine, but saying its dangerous is really not accurate as we have many people that are running them and have absolutely no issues.

[mcrews]

so, after looking at the pictures (you did look at the posted pics...right????) what are your comments?

[RiderofBikes]

melting and fire are completely different things... those instances were plastic is utilized, it needs to really have an incredible amount of heat for plastic to reach a "flash point" of sorts to burst into flames unless used with highly volitile chemicals in the manufacturing process that generally makes it dagerous in the first place, Im sure we all(who've completed belly pans) have made the proper material selection. and try to avoid things like this at all possible

Further more, when the plastic does melt, it melts only to a degree, like for around exhaust pipes. if touching, this may casuse it to melt, but only as long as its touching, once it stops touching, it will not continue to melt anymore. Kinf of a self remedy of sorts when watched carefully
