Bump stops with GC coil-over kit and Konis?
I bought a set of helper springs (which interfered with the shock collars on the bottom, and didn't fit well over the rubber gasket on the top, as well as some 14mm (??) rubber bump stops from TrueChoice, which didn't fit over the welded on flange at the top of the shaft of the Koni shocks, so I returned everything unused. 2 months ago. Still waiting to see my refund. 
In the meantime, for people with the GC kit and Koni yellow sport shocks, what did you do for a bump stop? Did you cut the stock dust boot and cut off the bump stop as shown in the instructions you received in your kit? I figured I'd sell mine, since they're in very good condition, so I didn't want to have to cut them if I didn't have to.
Is there an aftermarket solution to the bump stop problem?
Thanks,
Jim

Jim, I couldn't quite tell from your post whether you tried this already, but my Truechoice catalog shows that they sell four sizes of bump stops (differing lengths, ID, and hardness). The catalog is from 1999, but I would think they have got to carry this kind of stuff currently. Listed at $9 or $10 each.

I told TrueChoice what I had, they (supposedly) sent me the correct bump stops, but they didn't fit over the "collar" that is welded to the shock's shaft.

I bought my GC coilover kit used, so I didn't get any instructions with it. I simply cut my stock bumpstop, and that seems to work fine. Could somebody scan or take a digi-cam pic of their GC coilover instruction sheet? Cause I am not sure if I put everything on correctly, and its worrying me a bit. I had to use a grinder to make the threaded collar fit down over the strut.

"Welded to the shaft" Okay, now I understand. I have the M2/AD coilovers, and it looks like everything that is attached to the shaft threads on to the end of the shaft, so that installing bumpstops would not require any stretching (my coilovers came preassembled with bumpstops, so I didn't need to reuse any parts or take apart the stock coilovers). Glancing through the rest of Truechoice's catalog, some of the coilover setups have bumpstops and some don't. Of course you can always increase spring rates high enough to prevent bottoming out, but then you may be out of the ideal spring rate range. Did Ground Control have any suggestions for you?

Okay, 2 more off-the-wall ideas:
1. Cut the stops vertically with an exacto knife, but in stagger the cut line back and forth, so that you end up with a finger-joint (or dovetail if you have the patience). After the stops are on, use glue to lock the joint (there must be some kind of glue that works on cellular urethane). My coffee-induced theory says that on compression the stops will stay together instead of simply getting pushed off the shaft like they probably would if you cut a straight vertical line...
2. Get some K-Y, lube them stops up, and use that bad boy 20-ton press!!

Good ideas. I don't know if I will have to have bump stops or not or where coil bind occurs, because I've been too busy to bother with my suspension lately.
