The custom piece that will replace AST's perch will probably be made out of Aluminum 7075 and will look like this

I've put my hands on a used OEM top mount and tried to make the piece tall enough to bring the whole assembly to the same height as Ohlins + OEM mount in order not to mess with Ohlin's calculations of damper movement. The perch that came with AST's top mount could be used as it was (with just an inside diam enlargement from 14 to 15mm) but would have been about 20mm shorter than Ohlins + OEM top mount so the damper would have had less travel !

Very nice, my friend! :notworthy:
Can't wait to read/hear your review after the first track day.

rex, in the meanwhile, our friend Cristi installed his R&T on his BMW 3 series (very similar to mine and about the same spring rates). He was on tall winter tires but the ride was butter smooth (he said better than oem). We literally couldn't feel anything over bumps on the street ! Unfortunately it was raining quite heavy so couldn't drive too fast !
