GR86 Post your best update to your GR86 so far

Two things I've done so far:
1) Installed an AAWireless adapter - very happy with that, seems reliable and just makes life easier.
2) Swapped out the stock wheels & tyres for Michelin Cross Climate 2s on 17 inch rims - takes the edge off the ride, and a lot quieter.
Did you go for 215x45x17 tyres may I ask?
