I installed a set in my 87 Subaru Brat even though the track is a inch wider. Mine came out of a 03 and were removed when new to turn the car into a rally car. The ones I have are not heated or power. Also the 03 seats didn't have side air bags either. Been in my little Brat about 6 years or more now and Iove them. WRX seats back in 03 were suppose to be the same except they did have the side air bags. So you could probably use a set of them also if they would fit, the track for WRX and RSX seats are the same. They did have a leather option and heat.
