youve got RS-8's..... watanabe with bolts :(
yep :yes:
turn upside down ,place on matt or something "soft" :hmm:
grab a hammer and a piece of wood and hit the timber with the hammer around the inner edge of the centre
they are press fitted from the factory
hit around until it falls out :)
when you want to put it back in grab a file and give the face side edge a chamfer so the centre will locate and go back in
be careful when filing edge as you need to not touch the face surface :bash:
when reinstalling centre i normally put 1 bolt n nut in it and using an extension on n allen key socket i will put a bolt in opposite side and tap in with a hammer then put on a nut and continue in a cross pattern until centre is in and seated then bolt em up tight :)
2 days driving then retighten all nuts n bolts again... :D
hope this helps................ :hmm:
