Contact this eBay seller for R4 availability: http://www.ebay.com/itm/300763825942...84.m1439.l2649
I do not think that the R4 as discontinued as the last set that I got has been improved over the previous set of last year (mid cone is of different material). A customer of mine just got the last set from this seller 3 weeks ago.
For the price
, the R4 are the best component set for the E90. It even works quite great with OEM power.
