koni shocks/ tire size for rear

i have a set of koni single adjs with stock springs and i was wondering how to adjust the shocks they feel great now but can i get more from them


now for the tire size issue im running 275/40/18 on the rear and they tend to rub when i turn real sharp and when i hit some bumps my rims are 9.5 wide what size tire can i run with out scrubbing.

You got a 17" or a 18" wheel? 275/40-17 fits no problem at all. Is it one side or both sides?

The SA's only come with adjustable rebound. Although my stock springs are softer, I run my front DA's at 6 sweeps from full soft, and the rear DA's at 1 5/8 turns from full firm.

Start at full soft rebound at all four corners. See how that feels, then turn up the rebound 1 sweep at a time at both front wheels until the front starts to understeer instead of giving quicker response. Then back off the front rebound a 1/4-1/2 turn. The rears are done similarly.
