I read it as it was meant to , proves the brain is a good thing! HA , proves i have one i guess hehehe.
The XC will give you a taller cab and the taller rear bit but same as the V60 inside , i can't comment on dynamics , maybe some lower profile tyres would help it , use same as the V60 has maybe unless you want more comfort.
Lots of tuning stuff for them but the basic and cost effective way is a flash of the ECU tune , a big downpipes , after that its incremental and expensive. If you see the induction side upgrades they are very expensive for little gain , its a turbo , it would benefit more from the bigger turbo and maybe then doing the inlet side of things. Intercooler doesn't seem to do too much in reality according to some , on paper yes.
There is a new intake mani by Elevate , all along i have asked for flow bench figures and no reply only CAD simulation which to me looks like a dumb waste of money , a LOT of money....
Peeps and their money are easily parted when bolt on bits are touted!
