I will be doing a lift with the typical FJ coils and 5100's front and rear. I did search and read 80 pages of the compiled FJ lift thread but didn't see an answer to my questions. In order to end up with a level ride I'm told I need to use a 1.5 spacer on the rear coils. Do I order spacers for the FJ or for the T4R? I was surprised that the T4R spacers are 2 to 3 times more than the FJ's. I assume when it comes to the new top hats I need to use the ones for an FJ correct? I want to take my front coils and struts to a shop that can assemble them for me so I don't have to mess around with the coil compressors.

Also is there any brand of spacer or top hats that's better than another, any brands to avoid? I have seen spacers made from aluminum, poly urethane and rubber, which material to you suggest? Thanks for your advice and have a great day.
