Ok that make sense given the location of the radiator in this car. Where did you learn and is it necessary? At speed wouldn't just find its way thru fan, maybe at the expense of a little aero or downforce loss?
BTW been following your build posts and have more questions. I've been working on our build for 5 years now, on and off...but mostly off. Every time we start working on it again, my buddy Chris that I'm building it for makes changes and we end up 2 steps back. I recently agreed to finish it this year, under one condition. No more changes except for cosmetic or bolt on stuff he can update at final assembly! One item that is going to conflict is that he wants to redo the roll cage. I don't disagree because the RCR is crude and doesn't fit well. I told him I'm finishing the body work with the RCR cage and he'll have to work around that when we are done. I noticed how you redid your cage behind the firewall and starting me thinking about the advantages to that. Can you elaborate on the benefits of that?
