Need help with an 18" Weld RT-S setup. Any vendors?

[pickles]

I'm looking to go with an 18x10 squared, or staggered 18x10/10.50" RT-S wheel setup for the street like this > http://www.6speedonline.com/forums/american-muscle/226160-titan-motorsports-2011-5-0-mustang.html

But I have a few quetions.

1. Will I have any issues clearing brembo brakes?
2. What offsets will I need for nice fitment?
3. Any Weld dealers on here willing to give me a quote on wheels and actually follow through with it? If so, please PM me.

Thanks!
