Lowering my BU

Guys i have a question is there a science to doing this as far as rims and springs .What i mean is I just brought a set of 17'' rims and im going to buy a set of 225/45/17 tires and i was thinking i have to put them on first then lower the body by getting 1.5inch lowering springs .Or can i drop the car first then put the rims on?? is there any way that this could backfire on me if i do one before the other ??

there is no wrong way, i bought my 18s b4 my springs

yeah the rims and springs are completely unrelated but be sure to get an alignment after you ge the springs or your tires will not wear properly

Thank you guys this week im working Over time just to get my springs and thangs ...lol

One more question guys do I have to replace my stuts when I install my lowered springs or can I do them at a later time ?? The reson im asking is to delay spending so much cash at one time $$$$$$ lol

i still have my stock struts but i am getting kyb by x-mas
