I remember dad had a dunlop 60 series rear on at eastern creek once and it did head shake out of turn 5 a fair bit so yes it does affect stability.I,m all for raising the bike in preference to lowering the front,perhaps you can drop the forks in the clamps 5mm as well as putting the 60 series rear on.This gives a higher centre of mass at the front,better ground clearance,better tip in as the back will be 10mm or more higher,and your still tall enough to touch the ground,lol.Look at all the superbikes,they're all taller,as are there tyres and alot of them also have taller seats in them.Taller bikes stay on their sides and hold a line better.Having adjustable lowering links and fairly flat back tyres for the drags,with a low seat and converting that back to a stock seat,at full height with a 55 profile rear gives you a good comparison of the extremes of how the bike steers.
