DIY : Spring install

[detroiter]

Does installing the springs void the 60k factory warranty?

And one last question is can you take the TRD lowering springs, install them then get an alignment and your done? Or do you need one of the lowering camber kits or something like that.

I was reading a story about someone who installed some eibachs I think it was and they had to order a specific camber kit or something so the shop could do a proper alignment because they could not do it without it. I'm kind of confused by that story of the person and then about how it says the TRD lowering springs does not change the vehicles suspension and handling geometry.
