The heat is coming from the coolant and oil cooler lines. You may be better off searching options for improving your a/c. Ergo removing the plates on the front chassis wall will allow more air flow. If your a/c ever freezes over you'll need to move the temp sensor closer to the coil. Adjustments such as these will help. Unfortunately on long drives or tracking the car will result in warm sills. Some people have added insulation to the sills and covered them with interior carpet/fabric.

I've had the car for a year and the a/c hasn't freezed yet. I'm putting insulation under the carpet, but it still leaves the other half exposed. I'll look on opening up what you said in getting more air flow. Above 95 deg outside the a/c just can't keep the car cool inside. Europe doesn't get very hot I guess..

It's worse if you're at the track where it gets HOTTT, but I just take it as it is and learn to love all the small details, including faults.

My AC blows cold all the time, but it's also a later year car. You might wanna search for the AC improvement thread.
