After Jambo and seeing the limitation of the tyres on my TJ (31'' AT)

I am looking at 33" MT tyres.

after playing on the test track and travel ramp with my current tyres they just clear the guards so with 33 I would need to put in bigger bump stops limiting the upward travel

I was thinking instead of doing the bigger bump stops i was thinking of putting spring spaces in 2'' or 1.75'' would this work? (Much cheaper than new springs)

I am currently running Rancho 9000XL shocks, I have spoken to the supplier and the ones i am running will allow for the extra travel as they are used in the 2" and 4" kits

Any suggestions would be appreciated
