About 2 months ago, I installed a set of VWR springs on my GTI. Now, I ordered a set of the VWR sport damper to go with them. I want to make sure I have everything for the install, tool wise. Does anybody know if the front strut nut is a 21mm nut with a 7mm hex to hold it, like the OEM strut? I know some aftermarket struts use 22mm nuts. When I did the spring install on the stock struts, I used an impact to tighten it down but want to do this install with proper torque specs all around. I can't find any installation documentation anywhere that would lay out which sizes they are. Thanks.
