I would have to agree with Kahl et. al. - I have the 944 spoiler on my 924S and LOVE the way it looks... we dont get much of a chance to hit 125+ around here so looks rule over areodynamics..

Unless you have the tiniest hands on earth I suggest you take off the bumper. Two bolts hold the bumpers. Easy off. Either 15mm or 17mm.

Now the hard part. About half the time the screws/bolts that hold the rubbers on will break. I have removed about 30 of them and at least 5 broke one side. I suggest you WD40 them or use some other solvent that removes rust and then try to remove the nuts. If you see the shaft turn with the nut stop and leave it alone unless you want to buy a rubber from me.

b.) the 944 spoiler is not designed (aerodynamcially) for the car, like stock 924 one is

That is a bunch of crap! Are you kidding me? The 944 is a 924 with different fenders and quarter panels, aside from the drive-train. The 924 spoiler was put on just so Porsche could add another $200 option. The 944 spoiler actually looks good, and the 944 spoiler looks like it could actually provide some downforce.

And another thing, arodynamically??? Did Porsche really conduct too much wind tunnel testing on a car that they were making for VW?[/quote][/list]

why is everyone so argumentative?

When I toured the factory in Zuffenhausen they didn't just have a lunch break, they had what they called a quality break as well. The quality break was five minutes every hour taken as ten minutes every two hours. Over this time the workers would discuss what they could do better, and what could be improved on. One result from the quality breaks was a countdown clock that the workers asked for so that they could pace themselves and do a better job. Funny that the clock they chose counts down from 100 rather than 60.
Skemcin, sorry for that attack, I was in a childish mood and really pissed off because I couldn't get my 924 spoiler off.
But seriously, when Porsche wasn't designing the car for themselves, do think that they paid a whole lot of attention to the aerodynamics?

if porsche did not put its cars into the wind tunnel....then who did ?...Porsche was, is and hopfully will be one of the best build cars in the world. i'm 100% sure that the 924 has seen tons of work in the wind tunnel.
However the 924 is MORE aerodynamic than the 944...it has a LOWER coeficient. any downforce added will affect that number. the 944 goes faster so it needs more control at higher speeds...so they put special fenders and a big spoiler...but they lose in the other way.

924: 0.33
944: 0.35

You should be able to find a whole rear hatch, there have been loads of them at the Hershey swap meet in the last few years. It shouldn't be too hard to track one down in CA.

with regards to the rear spoiler
this has been gone over at length, and the rear spoiler does produce minimal amounts of downforce, what it is more used for is to eliminate turbulance at the back end, if you dont have a spoiler on a early 924 with a 4 speed you cant (apparently) redline 4th gear, there is too much turbulance, if you add a spoiler/wing then you can redline 4th.

the basic rule of thumb from my studies is that if the spoiler/wing is mounted to the body and is flush it is there to smooth out the airflow at the back of the car, if the spoiler is raised off of the vehicle then it is there mearly for downforce.

Yes, they did wind tunnel testing. I distinctly remember reading about it in Car and Driver back when they first came out with the 924 because the staffers were very impressed with the low drag numbers, some of the lowest at that time. I've still got that issue around, somewhere in a box with the other 29 years of Car and Driver that I've saved and my wife would enjoy burning, along with an unopened Grand Funk Railroad 8-track tape.

They were not, however, as impressed with the road noise and the motor.
