Recently did the Brembo retrofit to my 2001 WS6 and used the Eibach 15mm Pro Spacer kit. They came with extended studs that I measured to be 2-5/8" long from tip to tip. Unfortunately the 15mm spacers only give me about 1mm of clearance so I recently got custom 18mm spacers. For street car purposes, will the 2-5/8" studs I have on there from the Eibach kit be adequate for the 18mm spacer or do I need to go longer? On the 15mm spacers these studs get 11 turns and on the 18mm I get 8 turns until the torque wrench clicks.
