i got a mid '80s carrera frontend with the black struts, so i'm assuming i've got the stock 911 boge shocks.

the car is lowered quite a bit and i was hitting the 3-piece rubber stops frequently.
i was told i could safely cut the rubber stop down to 2 pieces, which i did and it helped quite a bit, adding more shock travel.

but i still bottom out occasionally on a larger bump etc.

so, my question is, for the boge shocks, can i safely remove a second piece from the rubber stop and run a one piece stop only ???

A non-effective (or missing) jounce bumper has a very sharp corner to the spring rate curve... right as it bottoms out.... and that leads to ugly things.

so, what if i:

- jack up the car, unload the suspension completely, move the rubber spacer all the way up on the rod, then measure the distance from the top of the shock to the bottom of the rubber.
that'll be my current effective shock travel.

- then, i remove the shock, i push the rod all the way down, mark it, then extend it all the way out.
that will give me the largest "possible" shock travel.

- the difference between the two should tell me how much of the rubber spacer i can cut off, if any ...

anyone see any flaws in this?

Sounds ok for measuring the total travel of the shock, just dont forget you still need the bump rubbers to do some compressing at the top of the stroke. If not you will still bottom out the piston.

Best case you will destroy a shock, worst case it could lead to very strange handling and punt you off the road (bent teener).

Best solution is raising the spindles and allowing the shock and rubbers to do the job they are intended to do for your ride height. (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)
