Did order mine from Maxspeed Motorsports, front 7mm/back 14mm, set with new bolts. Very nice quality and Nello is a nice guy to deal with. First 3 pics without, last 3 pics with spacers.
I also installed the front strutbrace from Schnell. I know opinions are divided about this mod but in all of my 'verts I had one and it made a difference in each of them including the Boxster.
Driving impressions are positive, car feels more planted and the front end is rigid, some of the front end movement is gone, less cowlshake, for sure!
No vibrations whatsoever, all in all very positive about this change and -of course- the looks!
On to the pics, again 1-3 w/o, 4-6 with spacers.
Later,
Andy
