Thoes are the shocks and springs I have.
I like them.

My wheels are 17" with 45 series rubber. I find the tire/fender gap to be perfect. The ride height is acceptable too - entering complexes and speed bumps are not much of a hassle.

I'm not sure how well the 18" will fit.. I don't really have much room to spare with the 17".

Not much more I can say since I've never had anything other than that and stock.
