Viking Speed Shop is great, Alan knows his stuff. I was looking to buy KWV3 and his price was $300 lower then anywhere else, long story short I found out that VSS can get pretty much any part you want even if it's not on their website, I ended up purchasing about $6K worth of suspension/drivetrain parts from VSS at great prices (price match + a bit more of a discount). I was also suggested alternative parts I should consider over my choices with explanation as to why it would suit my build better then what I choose.
I feel that I received above average customer service, and best prices when shopping for parts at VSS.
