I see that you can level out the front end with a pair of 2.25" front level spacers. My question is: should I just go for a 3" lift kit? I plan on running the stock tires till they are worn out, them maybe I will go with a 33" O.D. tire. Any suggestions? Thanks.
Depends on what you are planning to do with your FJC. Spacers are fine for leveling out the vehicle and providing clearance for larger tires, but do not have any positive effect on the performance of the FJC. Coilover suspensions give you more strength to handle the additional weight of larger tires / wheels, more suspension travel / articulation, and reduced droop when braking and liftoff on acceleration, along with reduced sway on turns. Spacers add stress to factory suspension by allowing the use of heavier tires/wheels with springs/shocks not designed to handle them.
So, spacers are better for your wallet in the short term, but if you plan on using your FJC for more strenuous off-road adventures, a true suspension upgrade will be worth the additional money in performance and reduced stress to OEM components....
