Welcome to the forum and the addiction! I appreciate the compliments on my mods and X5, I love it as well.
As to the RC vs JB4 debate, I am sure you've read all the comparisons, pros/cons available. I haven't tested a JB4 so I can't speak to that but I will tell you that I have used a RC Ultimate and the GTS Black. I am still happy with it and glad that I upgraded from the Ultimate to the GTS. I recommend you getting in touch with
r33_RGSport ASAP and request a quote on a list of mods, you know you want them! He delivers in many ways, great products and prices, as well as advice and support during the actual installation/mod process, whether it's the knee-pads or the RC install. Go with Ben.
You arent too far at all, I have made several trips up there this year to meet up with fellow Lone Star members,
P1et and
TallGuyX5, so you're in good company.
I think we need a central Texas meet and greet, who's down?
Cheers!
