Amazing build... very nice work.
Are you going to upgrade your suspension? I have KW V1's on my dd and TC Kline Double Adjustables on my track car and they performance isn't even close. The KW's aren't bad but for all the serious power and performance capabilities you are giving this car, don't ignore one of the most important handling components to keep it shiny side up!
