I am curious if bump stops on the two are different? I am installing a set of ITR springs and struts but am having to use some GSR hardware(including the bump stops). Should I trim the GSR ones?

thanks,

I highly doubt they are different in size. The R only sits slightly lower than the GSR. You can get away with gsr ones

 

man the r sping looks a good bit shorter than the gsr, atleast the 4 door gsr.

 

I have never seen the two compared but I don't see why they would bother using 2 different sizes when the ride height is only slightly different. Chop off the very top part of the gsr bumpstop if anything.
