Anybody using the R5/P7 for racing?

I just wonder if everything will even clear in the car. I dont want to put a tubular front end at this point....? Transmission issue is a concern as well. I have a motor found, so Im ready to pull the trigger....
I went with a tube front end just because the headers will be much easier to fab up, pics are in the current projects section, click the website link www.innovativemetalworks.com
