I used to put on the 96 spec EK4 seat then later I changed to 2000 EK4 seat after I did the 99 conversion to flush with the exterior as well. There are pro and con on both seats. The fabric on the 96~98 are durable but will stick with lots of dust and look used if not clean proper due the fact that it's micro fibre fabric at the middle. The color on 99spec looks stunning with blue fabric but the black fabric is not as durable as the previous version, easily worn out if heavily used. I love the later 99~00 spec though. :)
