I installed a Readylift 3/2 6 weeks ago and am I very happy with the results. Minus the CV boot issues I had the kit works very well. The rig looks good but I read that the FJ cruiser front coils when installed on the 4th gen gives 3/4" lift. I would like to install the FJ coils along with the Readylift 3" spacer to achieve a near level stance.
My concern is that I read the FJ coils are stiffer and with keeping my stock read coils will the ride and handling be an issue?

I would keep the stock rear coils because I understand the FJ rear coils lift the 4th gen about an inch + and I do not want the rear any higher.

Thanks for you input.
