People have written similar things here before, but allow me to gush over his service as well. I'm racing Sunday morning and have had a 575 on order for a few weeks. My payment posted only days ago, meaning that the wheel was ready to ship. Worried that the wheel would arrive a day late to race on, I called Renn and asked if they could let me know what was going on with the shipment. Next thing I know, I have a voice mail from Frank letting me know that the wheel is sitting on my doorstep. I hope I can do it justice in Philly tomorrow.
