Well i've had the RC lift paired with bilsteins front/rear for over a year now and absolutely love the ride. However the rear did start to sag slightly, give or take a 1/2". It was enough to really start bothering me.
So after reading alot about peoples experiences with the LL's I decided to pull the trigger and get a pair. I went with the WK versions (part# 58646) because i wanted to avoid the raked look and the stiffer spring rate. After the install i gained that 1/2" + back and she sits perfect IMHO. As far as the ride goes, they def stiffened things up a bit compared to the Bilsteins, but its in a good way. My cornering improved and going over bumps/pot holes is almost a night and day difference.... I was pleasanlty suprised
As far as price... i got mine for $90 out the door from my local Advance Auto. I used a promo code (retmenot124
) at checkout which saved me $40!
Hope this helps!
