Thanks! I documented everything as best I can in hopes it helps others in their quest for a lot of Golf R Mods. I have more things going on this week that I'll have to write about.
I love the HREs. They're hard to clean (compared to Cadiz) but I have a Wheel Brush and it does the job. 18s aren't as beautiful. If this car was on a trailer going to car-shows, I'd have 19s or even 20s with rolled fenders but it's a daily driver and track-focused car therefore 18 is far more friendly on my wallet (ding a wheel, cheaper to replace) and the riding comfort (I do 20k miles a year).
I hope my thoughts help. I can PM you a guy at HRE to talk to if you have any product questions. Jurian replies same day.
When I get around to wheels/tires, that'd be great! I'll PM you around then if I feel the need to talk to someone at HRE. In the meantime, keep up the good work!
