Axle bending - yeah it will happen. Cheapest option is to buy a spare and suck it up. Same for the chunking of the tyres, get some spares and live with it. Shoe Goo will only get you so far, if you run them out of the packet they will be more prone to chunking than truing them down. There's always another way - stop hitting things!!
Your driving progress will be measured by reduced spend on tyres and axles!!
The JFT option is fine but then you need new front axles and/or bearings so you can fit the JFT fronts. I'd stick to Contacts (reasons given above) and just try to curb your natural enthusiasm! With foam tyres, the best times are when you drive slower than you think you need to, so go slower and practice getting the right lines as close to the markers as you can at the highest corner speed you can maintain.
@Mark - on here we have quality, on FB you only have quantity!!

Only kidding pal, each has their uses and it's nice to have some different uses on here.
