Not sure anyone's reading, but I'll put it out there anyway.

I just got back from successfully installing my BC Racing coilovers, and slapping a quick alignment on my GXP.

I have to say this is a very worthwhile mod, and the BC's deliver a whole lot of performance for the money.

...

We used a hole saw to cut a little hole in the trunk so that the rear adjuster dials were accessible without removing the wheel.

Conveniently, the carpet was already cut in that location.  I will clean up the loose fibers and probably make a rubber grommet later.

(Image removed from quote.)

Anyway, a very worthwhile and enjoyable day.  I really believe the BCs are steal for the money.  The handling and neutrality of the car (and now adjustability) is really light years ahead of where I started.

Ben L, I know it's been nearly two years since you posted your great message about your BC install, but I'm hoping you can help me with mine.  I just had mine installed last week, and I haven't had a chance to drive it much yet. (Obligations and rain.)

I see from the pics above in your message that you cut your holes in the trunk bottom in the little bald spot (no carpet) next to the gas tank hump.  I believe that my adjuster knob on the BC's is touching, or close to touching the bottom that surface. Did you cut the holes before or after the shocks were installed?

I am afraid to just start cutting with a hole saw. Or even if a hole saw is the best tool (as opposed to a Dremmel or mini-jig saw??)  Of course I want to have the hole centered over the adjuster knob, but I don't know how to measure or position the saw.  And I don't know what the optimum diameter of the hole should be.  I'm guessing that the center of the hole should be just about at the edge of the carpet about midway in he 90 degree of the curve.  Would you agree?  Did you find the location to be close to identical on both sides, or did manufacturing differences cause the location to be slightly different on either side?
 
Can you give me any pointers?  Also, how did you finally decide to make a cover for the hole?

Thanks.

Don

Randy cut mine, and he used a hole saw.  It has to be big enough to get you fingers in there to do the adjustment.  We did mine after the install, and it is the back half of the bald area and the same amount from the carpeted area.

I actually bought these coilovers off of Ben :)

I put the coilovers on BEFORE cutting the trunk.  When I went to adjust them for the first time, I realized that the knobs were right up against the trunk liner.  That's when I ended up cutting it up.

I have cut the holes in the truck also after installation of the KW V3 coilovers.
