Second question - in order to fit OZ Ultraleggera I need to fit wheel adapters, is this one ok? https://www.ebay.com/itm/5x130-to-5x4-5-5x114-3-US-Wheel-Adapters-1-thick-14x1-5-studs-71-5-Bore-x-4/171952702245?hash=item28092e0325:g:WRsAAOSwb3laJDX ~

It has 14x1.5 and 71.5 mm bore which should be ok for Boxster. As they are 1 inch wide, will those wheel adapters do the same thing as 1 inch wide spacers?

Thank you,

Darjan

First Answer: The discs will... but S discs w/ any caliper likely no and since you'll want calipers to stop then you need at least 17" wheels to make fit... not to mention will be cheaper/easier to find 17" tires in long run which are getting increasingly difficult to find abundantly.

Second Answer: 5x130 is correct size pattern for Boxster hub/wheel bolts. If OZ wheels are 114.3 dia then that is correct right SIZE adapter BUT image shows 5 stud where as description says 4 stud. Neither explains there is a difference to help you know which is correct. As to style, yes that set-up will act as a 1" spacers. That design 'spacer' is better b/c you would never want to use 1" 'sandwich' style spacers as longer wheel bolts, even if correct length & pattern matched, could not adequately handle the load. No idea on the quality of those and with any spacer over 5mm you really want them hub-centric...

My recommendation... particularly since track focused, you want to keep the set-up as simple as possible. Buy 17" wheels that fit w/ the correct offset and wheel pattern to begin with and avoid spacers all together. At very least, buy a complete package deal from one reputable vendor from start. Then proper fit is on them to make right. Otherwise not only might you be compromising safety but you could be stuck trying to return (not likely) or sell at a loss ill-fitting parts bought wrong.

Good luck
