I got mine (black) from The WRX store. ILP Performance had the silver or grey. It seemed like that as soon as the shipment came in they all went fast. One day no one had them and then the next day everyone had a few sets - no it seems like everyone has them on back order.
I did seven runs yesterday with them on with Ecsta V700. There was no rubbing. The only rubbing that I had was from the night before when I had someone riding with me and the right fender plastic got scuffed. With no one riding for all of the autocross runs there was no rubbing.
It looks like the Slipstreams, V700s, KYBs (set at full stiff with stock springs) works pretty well.
I have to next try the Hoosiers in the same size. Their section width is 9.3" (same as the MXs) vs the 9.1" of the V700s. Kostamojen - no chance of putting back on your stock springs to see if you rub with the MXs?
