hello there.

Im new to this. I bought a 2006 IS250 AWD in September 2016. Lately, I've been thinking about modifying it. It is my daily vehicle and i have a baby on the way so i would like to keep as close as stock feel as possible but eliminate the wheel gap

My questions are:
1) Which lowering springs is the closest to stock feel?
2) is anybody running H&R lowering springs on 18 wheels? That is the set up im planning on doing..May i please see a picture if you are running that set up that would be a great help
3) i live in edmonton, canada. does anybody know a place in canada where i can get parts? i dont mind getting them anywhere but shipping wise i would like to save money on shipping while getting parts.

im sure there was a post like this posted before but like i said im new to this so please be nice to me lol.

thanks in advance
