Audi TT Electric Fans - worth replacing?
in an effort to remove some weight from the front of the TT, should the Standard electric fans be swapped to lighter more effecient items?
Just a thought?
Have removed almost 50kg form the vehicle already and lost a kilo or two myself, will replace front seats soon with some lighter sparco items.
Has anyone performed a battery location to the rear of the vehicle?

Your suggestions?
50kg is mainly all from the rear of the vehicle in the form of interior trim etc.
the electric fans look bulky and hence i thought a good place to strart when i cange the belts.
i know i will have to have it corner weighted so i can better distribute weight of the vehicle eg: battery relocation, fire extinguisher system, tool kit, etc.

Battery relocation was my main suggestion. A few pics in my poster to explain...
So taking this out from the very front of the car

Running 4 gauge cable wrapped in heavy duty nylon hose to the rear...

And then eliminating this chunk from the left side of the rear bumper
<img src="http://pictureposter.audiworld.com/9/ttdoor_stop.jpg">
And installing the battery on the opposite diagonal end of the driver
<img src="http://pictureposter.audiworld.com/9/3_pc_ramps2.jpg">
Ignore the ramps (stuff next to battery). I was showing my 3 piece "rhino" ramps which fit behind the roadster
Yeilds an overall weight transfer of ~70 lbs to the rear from the front, even though the weight savings is about half that - the bumper weight
Leaves you a lot of room in the engine bay to be a little creative

The next weight savings is from the lighter exhaust. I don't see much in the engine bay that's fairly heavy or worth taking off. Fans usually weigh a couple of pounds - at least I have a loose one sitting from a Passat / A4 that I had verified. The TT fans are slightly smaller.
My custom intercooler setup is a little under 3 lbs lighter than the stock plumbing. But at least taking out weight from extreme ends of the car help a bit in cornering.
There's also wheels and brake rotors which help against weight and rolling inertia also.
Nice sig BTW. Makes it hard to type and think

What is the piont of the bumber weight?
<center><img src="http://pictureposter.audiworld.com/9/ttdoor_stop.jpg"></center><p>is it just there for weight distribution?
want to change to a dry cell battery for the rear as this will cut weight even further.
Have Supper Leggera 18's wrapped in Pirelli's (Light tyres with a total saving of 3 kg per corner) ready to go.
Seats will be next with an expected saving of 30 kg when replaced with Sparco Circuits.
Not willing to part with the air con not in Australia 40 deg plus days in a black car, no way however, i know that would cut front weight dramatically.

Yes. When the TT was 1st introduced in ~98, It came as a Front Trak version...
with the VW mark 1 (or 2?) suspension. The back was fairly light.
In some sections of the Autobahn, some early TT adopters got into fatal accidents when they crested a downhill slope that had a slight turn. The rear lifted on the turns (with the aid of likely throttle lifts) and the car could spin, with the unfortunate using trees to stop this motion.
To remedy this, later model TT's were fitted with the rear spoiler for downforce, mark 2 (or 3?) suspension which has softer and bigger bushings, stiffer bars, which gave the car more understeer. Then they added the bumper weight, again to help keep the rear planted to the ground.
There are people against this removal, because of the facts it was placed there. But then check with the same people only to find out they replaced their exhaust - and replacing the rear heavy muffler could remove about the same weight as the bumper weight - so it's a counter argument.
Our car is a roadster which already has added toneage from all the convertible motors and extra beams, reinforcement. It doesn't need anymore weight.
For yours, keep an eye on corner balancing and front/rear distribution. Since you have a better tendency to eliminate rear weight as you already described.
Besides, our 2700lb Acura has ~70/30 weight balance and we never get in trouble with it. It will easily oversteer on AutoX though.

On the AC standpoint, I think when Sharon or Corey (hardcore AutoX folks - yellow S4 in AWE website)
removed the entire AC unit which included the compressor, condenser, evaporator, collector and all the plumbing, it weighed under 30 lbs. I think under 20lbs but I can't remember. I can see how it will be of greater inconvenience down under I'd keep it too.
One of my cars has no AC. I can't live without anymore in California summer months
