You have plenty of room...its adjusts so no problem...Never really noticed a dif in the ride...it hooks pretty good...thats one of the reasons i got it....kinda helps out both areas...i pulled 1.9 60s with Kuhmos...so it does help there..
I took the upper stop off when I removed the dogbone, so it just hits right on the rearend..i never really thought much of it when i removed that plate...its what the snubber uses as a stop...
My first adjustment was to low, as the rear "bottomed" out...i kept moving positions til the ride came back over bumps....
