Cut my springs, thump, and bumpy ride.
Hey all!
In an attempt to get rid of the horrible wheel gap my XF had when I got it (at 65k miles, now at 75k), I cut my springs. I took one coil off the front and 1.5 coils off the rear (the rear gap was almost 6 inches).
The car now sits much flatter -as opposed to the huge rake it had before- and more flush. It doesn't look like its rubbing in the wheel wells, but I have a few concerns after my shakedown test.
A) I went over a good sized bump getting onto the freeway (stopped at a light, turned into the on ramp, which has a 3-inch dip across the width of the road) going about 5-10 mph. Heard a pretty good thump from the rear of the car. I haven't heard it since, but I worry that I have overlooked something back there that could bite me in the *** (pun intended) later.
B) the ride is considerably bumpier than it was before. I understand that cutting springs will increase spring rate, but now even slight bumps have me literally bouncing in my seat. Would replacing shocks help this? Or did I just make my car stiff as hell unless I get stock springs?
I'm a base model 2005 NA. All stock, except the rims, but they are the same 18/19 stagger.
Thanks everyone!
