Still trying to finalize the suspension upgrade I want to do on the JSW. Wasn't completely sold on lift springs/spacers and originally was just going to upgrade to the b6s w/new stock height springs but after reading all 19 pages and distilling it down, here is where I have arrived:
*Only really to need to read the last 3 or 4 pages of this thread.
*Lifting with struts/springs more advantageous than spacer kits such as forge.
*Bilstein B6s up front and B6s in the rear unless there is a reason to consider the b4s?
*IDparts lift springs set unless there is a strong argument for OEM tiguan F/JSW towing R?
FWIW, I currently have 225/50R17 Michelin Crossclimate 2's on my stock height JSW TDI that have been absolutely outstanding year-round here in Colorado. 3 peak rated, so good in the snow that I didn't even bother swapping to my snow tires last year (I am not saying these are as good as a dedicated snow tire, but if you can only have one set these are something to definitely consider). Amazing in the rain, even in downpours I don't need to reduce speed until visibility becomes an issue.
This larger plus 1 tire size will affect the speedometer readings by about +1 at 30 mph, +2 at 60 mph, +3 at 90mph, etc. Haven't worked out the exact MPG penalty but the cars reading has stayed consistent at around 41mpg with both the stock and plus 1 size. I'm sure there is some way to work this out but I haven't bothered.
As for some folks who think the larger tire size with affect the clutch on my manual, I am open to reasoning but I doubt it. My winter setup is 16" steel rims with Bridgestone Blizzaks and I am almost certain they are heavier than the Crossclimate 2 w/stock 17" alloys. I haven't weighed them yet but I will update when I rotate or swap the tires.
Just trying to contribute as I have been scraping information off this forum for years, time to give back. Hope some of the info helps. Will update once I make time and do the suspension/brakes.
