revtek suspention lift

I just bought and 2003 SR5 Toyota 4runner. It is my first Toyota and I am very excited. I always liked the raised look of the older 4runners and want the same look and clearance for my 03. Just wondering if a revek suspension lift (3inch front, 2.5 inch rear) is ok? Will I be sorry I did this to my new 4runner? Or is this type of lift fine? I don't do any serious off roading (Gravel roaded and rutted trails) and will stick with my stock 265/65-r17 wheels. I am planning on having the local Toyota dealership do the install. Thanks for any info.
