Just finished installing mine tonight. This thread has been a big help from start to finish. Thanks to all that contributed!
1. Wear gloves to get a good grip on the stock shift knob to remove it, that really helped me out since that SOB is in there good!
2. I had a difficult time removing the stock base ring from the stock boot, it's really glued in there! Just be patient, once you get enough off the rest seems to come off easier.
3. I didn't glue the M5 Boot to the stock base ring, just need to cut big enough holes around the clips so they can clip in freely.
4. A second pair of hands helped me a lot when performing the final installation. Luckily my wife was game to help me out tonight (thank you baby Jesus! lol). The second pair of hands came in handy when keeping the leather tucked in cleanly and making sure all the clips were securely clipped in tight. If you did this correctly, the base shouldn't pop off without a nice tug like the initial removal.
It's definitely a lower height than stock, but I like it...I can still rest my arm on the armrest and shift no problem. The shifting feels amazing with the heavier knob. 1st to 2nd is definitely improved for me.
Just thought I'd share my personal experiences and opinions, hopefully it'll help some of you out. Thanks again for this thread! Cheers!
