Hey guys. after hours of searching the internet and asking on different forums, i got fed up and decided to dive in the deep end and convert my 4door recaro sports seats to 2door seats using standard E30 coupe seat parts. i had seen a set before that had been done but never saw how. I hope this guide saves someone a lot of time and effort. Start by laying all the 4 seats you'll need to do this on the ground. 2 regular coupe seats 2 recaro sports seats 4 door. i've already started at this
