It looks very very nice indeed. If I were to do it all over again, I would definitely go that way. How is the comfort?
I emailed H&R trying to get some specs for spring rates or difference between the model for Cayenne & Touareg, they do not share the information. Apparently they are progressive springs and there is not one general way to measure. Maybe I am over-simplifying things, but it sounds like it should be as simple as force VS spring compression. I emailed Eibach to get an idea of the spring rate, no luck there either.
Anyway, I'll measure the Eibach springs force VS displacement on Friday.
Installation is schedule to be Tuesday August 17th, I should have received my rear top plate by then!
As for cost wise, The B12 kit was 1750$, add another 345$ for the rear top plate. I am not installing them myself, got a quote for 6.5h @105$/h since I am bringing my own parts + 100$ for the alignment. Ride height shouldn't be significantly different, but I doubt it has been aligned since it left the factory so it is worthwhile considering tire price in 20in.
As for wheel offset, I am running 20in Cayenne wheels (ET60 I think) with 10/15mm spacers Front/Rear
to be continued!
