Nice pic Jimmy, you are too smart for your own good!

Looking at the pics you can see a distinct difference in the XX4 against the 501x, the XX4 has its heavy components more central and closer together. The 501x has them further back and it has the metal centre bulkhead housing he slipper. The weight further back on the 501x does give it superb rear end grip and traction out of corners, it also make it understeer, ideal for JIM D!

As you know I like running my 501x but there were around 4 or 5 501x's running at Bury last sunday and none of them were good on the sleeping policemen jumps.

I tried a direct comparison same tyres etc on the XX4 and it jumped a lot better, I could nail it everytime, however I must admit that the XX4 had way too much acceleration (my fault as to cope with crap cells at the start of the Nationals i turned the wick up on the speedo, my new cells now caused a certain amount of too much wheelspin)

I did consider cutting the gurney down on the wing and to be honest I didn't get round to it.

If there is a next time at Bury I will try the wing mod you suggest.
