    Hi Rob. Not sure if this has been discussed but have you seen the issues Bugatti had with tyre valve stems at high speeds. The centrifugal force on the stem amounted to many kilos squshing the stem down towards the rim, in addition the force would open the schrader valve deflating the tyres. Just a thought now you have larger wheels and are talking of 200mph+. Keep safe - CK.

    So for you and Isaiah (sp?) Cutting aluminum with a jigsaw is super fast and easy... But you have to keep the blade clean and not gummed up. Pick up some aluminum specific cutting fluid. I like A9, but there are others. Run a small line of the cutting fluid along your cutting path and I promise you that your cuts will go by so quickly and effortlessly and your blades will last seemingly forever. It's find of ridiculous how much difference it makes when cutting thin aluminum sheet. 😂
