I've been runnin em for roughly a year and a half. Love em! My thoughts are: factory level one, while in summer mode (19 inch wheels) was just a bit too tall yet however, I struggled with the idea of the 402 mod essentially lowering all 4 levels across the board. After all, I picked the allroad for its "swiss army knife" versatility, allowing me to strap a snowboard rack on the roof in the winter, blast off to the slopes with gobs of ground clearance if needed,while lowering her back down in the summer months and still maintaining a proper stance. IPP leveling arms allow the "best of both worlds" scenario. You can essentially maintain a factory level 3-4 while achieving a lower level 1 for the summer months. Super happy with my decision!
With all that being said, Its paramount all maintenance is up to date.
IF your control arms are currently fried, clunking around town, obviously, lowering it further will further dramatize these ill effects.
IF you are currently working with a weak compressor pump, obviously, raising and lowering the cycles further will work the pump that push harder, potentially revealing its weak points.
I made it a point to rebuild pump (bagpipingandy.com kit) as well as replace all of the upper/lower control arms prior to IPP leveling arms and she rides like a dream. Slightly bouncy on level 1 however that's to be expected.
If you have realistic expectations and stay within the limits (not go too extreme 402ing up/down) you will most likely be stoked. Hope this helps! N8.
