You needto make your inner arms straight, so you to either flip your XA to A and go A-A, or get an XE/E split mount and go E-E. A-A will be 3mm narrower track than E-E, and A-A will be almost the same track width as you have now so if you want like for like handling that is probably the best option. I learnt heaps on this subject from a blog on thercracer.com.
