I'm not saying you guys have to beware them. Do what ya want. Some of us prefer to have a safety back up in case they fail. I've been at a shop that had a regular stream of customers come in with air bag issues. I'm basing my opinion on that. I'm not a fan, but that's just me (see sig )



Agreed.
That explains a lot. If you want to see the most hack installs, look no further than a lot of "show" cars.

That's quite the assumption.

Im sure the OEM standards are higher but no reason an aftermarket product cant be made superior. It all comes down to cost. There are very inexpensive aftermarket air bag options on the market and others that arent nearly as affordable. Like anything in life its a compromise.

We're completely derailing this thread but I think we can agree its a matter of opinion whether a leaf spring setup is superior to an air ride or a cable with a winch. They all have their strengths and weaknesses but it doesnt make any particular setup good or bad just different.

Personally I think air ride has proven itself over the years and to think that if its good enough for semis no reason it cant be made reliable for a lil 20' car trailer.

I'd be okay with trailers that had airbags from an OEM supplier, of some sort. Do any?
The three trailers I saw used aftermarket stuff. So, i'd definitely still like to have safety locks.

I agree this is really not aero thread fodder. One quick comment. Airbags can be very reliable and are even used in commercial trucking as well as regular tow setups. A big difference is that there is typically mechanical failsafes if those systems fail as well as monitoring electronics. I'd worry that airbags would fail on these trailers and I'd drag frame.

What about the other option, removable front bumper/splitter setups. What do people have? If I could remove the bumper and large splitter quickly, I'd save myself big $s on a fancy trailer and space in my truck for ramps. I've seen quick release bumpers, what do people do for proper high down-force splitters?

Case in a point. A local Evo show car had an airline fail the other day. Something rubbed through it, because it wasn't installed properly...

So it's easy to deduct that all show cars are of the same build quality.

With the cars and trucks I witnessed, The lines didn't go and the electrical systems didn't die. The bags popped. Yes, they were installed properly (one was by the manufacturer). Yes, they were used per direction. I could go on.. point being the bags failed.
Where the aftermarket systems used not made of quality parts? Maybe. Are the bags on trailers the same quality? Maybe.
I think an airbagged trailer should have safety stops, some of you don't. That's fine, especially because none of us will buy one, anyway.


But, we've been off topic long enough, so I concede. You win. Airbags are the shiznit and are 100% reliable.

I'd much rather read about aero bits for our cars.

Lets get back on topic shall we everybody?

My front bumper has 4 quik latches installed and it comes off completely once u release them. can have whole bumper off in 30 seconds. perfect for last minute repairs or work at the track etc!

I have quick releases to replace the annoying screws @ the top/end of the bumper cover (under the headlights). Other than that... I tried using OEM push-in fasteners along the radiator support. That seemed okay. Without my front crash beam, the bumper moves a ton without a splitter. That's a bit of a bummer. The main reason I have no splitter is because I can't find a way to get it on/off in a reasonable amount of time.
I've seen a few ideas on this site, but haven't been smitten enough with any to try. I remember reading a thread where someone wanted to make a "universal" kit that anyone could adapt to their splitter. I'm hoping I or someone else comes up with something super simple and quick LOL

I'll try to get you some pics of mine. It's connected at six points. Two on the bumper cover on the bottom that are connected to the side of the frame rails with brackets in front of the wheel well, two to the rear subframe where the east/west brace connects, and two on the front for the support cables which are connected to my crash bar (I'm sure you could find some alternative mount for that). Can get it off in 5 mins, getting it back on is a bit longer if you only have one set of hands.

If i get a chance ill upload some photos of my front end setup for you.

My splitter is moulded onto my bumper. my old splitter was screwed. i always attach them to the bumper and then just have a bracket at the back with a pin or quick release fastener.

Can literally pull both my bumpers off within about 30 seconds. 4 pop quick latches and the pins under neath and the whole thing comes away. other people mount the splitter on rails off the chassis itself and it just rests on the bumper so its not physically attached, they pull the bumper off and leave splitter in place. then u just have 4 bolts to remove splitter off rails. essentially they look like upside down rear wing uprights.

my bumper is held on by 4 of these: http://www.quik-latch.com/

Essentially the same system that the V8 Supercar front bumpers use in australia. Mint system for when ur racing and time is short. Ill try post some photos for you tomorrow

Pics please. Quick release splitter/bumper units really sound excellent. I'm not sure I've seen any good DIY or writeups on the proper frames/mounting systems for these.

Looks like a few others in this thread have good setups as well.
