Resurrecting this thread. Ordered KYB AGX fronts and rears. I also ordered the rear upper mount kit and the boot kits. The bump stop/boot kits are SB101(front) and SB107(rear). Can anybody share how the rear bump stop/boot goes on the shock? The center hole at the top of the bump stop is just large enough to squeeze over the threads at the top of the shaft, but not over the stop. The instructions(next to useless) mention soap and water but it still seems too small and begins compressing the shock. Is this bump stop supposed to go below the stop? I would assume it has to below the stop, if it does not the assembly will not be stable up top when assembled into the mount
>shaft stop |bushing > sleeve (inserted through mount) < bushing < washer < bolt.
Should I drill the bump stop out slightly or is it supposed to be that tight?
The opening on the bump stop is tapered to 5/16"(approx 8mm), while the stop is 5/8"(16mm) followed by a ring that is approximately 23/32(18mm). The shaft itself above the stop is just shy of 1/2" (9mm) so its already a bit of a squeeze. I just see how the bump stop is supposed to fit over that stop.
The picture is of the rear shock (741014) and rear boot/bump stop (SB107)
Another couple of questions.
The front mount is an OEM.
The rear KYB mount kit (SM5091) is being assembled into an OEM EVO mount housing. Is there any reason why there appears to be 1 extra grommet in the kit? The grommet in question is the one on the upper left. The grommet is similar in design (same diameter and bore) to the one on the lower left except thinner and a larger taper. Is this simply an alternate bushing based upon application or does it go into the assembly somewhere?
One notable distinction is that the KYB instructions show the top bushing inverted from what the service manual shows. Of course both diagrams are iffy at best. I will be comparing the old shock assembly when I disassemble it from the car.
Assembled on shaft with the actual mount housing and upper spring pad omitted.

Is there supposed to be any type of lubrication applied to the mount parts upon assembly or do they go together dry, front or rear? If so, what type?
I'm taking detailed measurements of all parts independently and will be posting diagrams and tables of the entire shock/strut assemblies to hopefully take some of the guesswork in calculating height with various springs/mount/shock combinations.
