Hello mate and welcome to the site. Its great to see any International intrest on here and especially for someone who is planning to use their car for competition. If you have a build thread on another site you could post the link in the Members car section or even better copy and paste it into a new thread on there so everyone can see it. Here is a quick link to it mate, you just click on Submit members car and fill in the blank space below. You can come back anytime and edit it, add to it or change it.....

I looked through your build thread and you seem to be coming along well. Its a time consuming process we all know, but you are not really getting sound advice form people with experience of building EP time attack or drag cars. If you look through the TM Devlopments section in the Traders forum or The Peformance Zone section of the Specific forums you may find what could work best for your needs.
I hope you can get something from the site, either information or contacts that will help you reach your goal. We all feel proud at a members success so keep us informed of whats ahead please.
