Be aware if fitting Boosts on 30mm spacers that the corners of the hexagon heads of the drive flange bolts will foul and gouge the inside of the Boosts unless the heads are aligned precisely so that a flat parallels the circumference of the flange.

An easy solution to this is to replace the hex head bolts with hexagon socket-head cap-screws (what people tend incorrectly to call "Allen bolts"). The originals bolts are specials since they are grade 10.9 (rather than the usual 8.8 for 'standard' HT bolts and screws) but socket-head caps are 10.9 as standard, so easy to obtain and much cheaper.

You can see this in my photos earlier in this thread.

Thanks for warning blackwolf. But i guess damage is done already. I'll check.
Keeping hex head bolts which have been aligned precisely as you recommended would be wise solution when it is compared to replacement with socket head cap screws. Because by this way, drive flange bolts won't ever loose again. Smile
