What If Build Ideas...for Land Speed Racing

I get why you were keeping an eye towards 200 mph, and is a good idea to but sometimes It makes it so daunting that stops you from even starting and accomplish an achievable goal,
which to build from.
the daunting part was... is what I have ok to build off of or start over. From here, going to get another 40ft of 1.75x0.120 DOM to keep on working. Too much cage and support is just enough it seems. Not sure about when a funny car halo comes into effect.
