Too many "free" deals at the end of the transaction/

Order # 26695 I ordered an EGT and a gauge pod. It showed up at my house 4 days later exactly as I had ordered it. The Prices are unbeatable!

seemed a bit hard to find products, but the prices were great and delivery prompt

This is the first time I've ordered from this site, but things look good from what I can tell so far. They had the parts I was looking for (including a fairly specialized racing part) for a price slightly lower than other places I had looked, and my order shipped the next business day. At the time I wrote this, they were also offering $5 back on my order for writing a review. ;-)

Thanks for you swift respond for the email and your accurate information and i hope to deal with you again

Great prices and super fast shipping. Good job.
