2 i6 engines welded together 2.1

what we need is big tyres that are too small on the front.... just pretend that they're 90% rubber and 10% air, whilst the wheel is 2 inch thick iron lol

basically this gives drag tyre options, wings, and a giant supercharger

it now uses the new t-series models, I've also added a dual front axle extension, and giant drag supersingle rear tyre. I made an open wheeler race variant too.
