redls1T/A

So I recently started getting more into suspension tuning with my T/A, my buddy's shop gave me a good deal and bought myself the KW variant 3's. however, I didn't realize the rebound setting was on top of the strut and when installed, its pretty much impossible to adjust since our cars don't expose the top of the Coilovers in the engine bay. Has anybody had any ideas on how to adjust while on-car other than drilling a hole or unbolting the whole thing. just to set the clicks...? btw my car feels like a beamer now, suspension wise..
