Never knew Bilstein had a document recommending heights. That would have saved me time and money.
I have the b14s and have run them at a range of heights.
I found personally that the best set up for me has been 1 cm lower front and rear from the 197 cup chassis height.
It takes bumpy roads like a champ and does not get unsettled over bumps, and dare I say it more compliant than the 197 non cup shocks and springs the car came with.
You do have to cut some length off the rear bump stops as mentioned previously, as even at the highest ride setting in the rear they sit on the bump stop already.
Its pretty easy to take apart and cut.
Front ride height from bottom of the rim to the guard at my happy set up is
575mm
And rear
585mm
I live on bumpy roads all around me and daily the car and really like the set up now in the b14, whereas previous I hated them and wanted to get rid of them. I run standard wheels and tyres and just adjustable sway bar links.
Attached is a pic of the cut rear bump stop. It's super easy to do, just try make sure you cut it straight haha.
Hope that helps as I asked on fb groups for recommendations also and got the usual "yeah bro, low but not too low" that page shits me no end haha.
