At 180 lbs you would be in the 18-19 kg range if i remember correctly(stock is 15.3 kg). Yes i would try slapping the spring on and installing the shock, then play with the damping adjustments to see if you like the results. Even if you have to max out one or both adjustments it doesn't matter if you like it. Ideal, no, but I'm sure it would be an improvement over stock. I think the F4i shock is around 3/8" shorter then the vtec so you have to make up that amount by shimming under the top mount, may require a longer bolt.

Thank you!
Do you have any idea of where I should look for compatible springs? Are there any OEM springs that would fit the bill?
