I am changing my spacers from 25mm to 17mm. My friend gave me the smaller set but it didn't come with bolts. I think the 25mm spacer used the stock boxster bolts. Can I use the stock bolts with the 17mm spacers also? With the 25mm spacers the lug part was recessed more than with the 17mm. See pics below of 17mm. Is the stock bolt ok to use? The wheel does fit over the bolts as pictured in the second pic. Thanks.
