AlbatrossCafe Posted October 21, 2017 Share Posted October 21, 2017 (edited) Hey all, bought a pair of wheels with some positive offset, so I got a set of 25mm wheel spacers all around to make them fit. I went with the pair listed at zcardepot: https://zcardepot.com/wheel-spacer-set-pair-1.html I was hoping this would "ensure" that they fit all around (since zcardepot specializes in z-cars) but alas, the fronts do not. On the front (stock) hub, it seems that rubber-ish (might just be gunk lol) piece sticking out doesn't clear the center bore of the spacer. I need about 1/8" more clearance. See the following pics. Should I have expected this? Is there just gunk build-up on my car that needs to be cleaned off? What is this rubber extension anyway? Am I screwed unless I get new hubs? FYI - the wheels themselves have 73.1mm inner bore (~2 7/8") and would likely fit on the hub if they were correct offset. I have to use a hub ring to properly center them on the spacer outer edge. Gap when fitted: The center bore appears to be machined out to compensate, but it is just a bit too narrow: OEM wheel has 2 7/8" inner bore: Spacer has 2 5/8" inner bore: Edited October 21, 2017 by AlbatrossCafe Quote Link to comment Share on other sites More sharing options...
AlbatrossCafe Posted October 21, 2017 Author Share Posted October 21, 2017 Could I have a machine shop bore out the center just a bit more so that it fits? Quote Link to comment Share on other sites More sharing options...
JSM Posted October 21, 2017 Share Posted October 21, 2017 Geese after all that. I don't know why machining would hurt. Just go a little down and out, but I agree it should fit. You want me to measure the ones I have? Quote Link to comment Share on other sites More sharing options...

I found there was a machine shop that specializes in auto stuff and especially on wheels so I'll give them a holler and see what they recommend.

Mark N Posted October 22, 2017 Share Posted October 22, 2017 It's hard to tell from the photos but are you sure that rubber extension you mentioned isn't an old spigot ring stuck to the hub? Quote Link to comment Share on other sites More sharing options...
NewZed Posted October 22, 2017 Share Posted October 22, 2017 Remove the gunk. Everything in that area should be steel. You don't want any gunk between mating surfaces of the wheel and/or adapters. Verify that it doesn't fit. Call zcardepot and get them to send you the right part. Why accept the wrong part from a zcar "specialist"?

I don't think so... I scraped off the gunk from that inner bit with a flathead screwdriver and that flathead wasn't getting caught on anything. Plus the previous owner left this car 98% stock so I doubt he would have randomly added a spigot ring (especially for OEM wheels). Gonna try to really clean off everything really well as @NewZed said and see one more time if I can make it work.

AlbatrossCafe Posted October 23, 2017 Author Share Posted October 23, 2017 Got a response back from zcardepot... "Some years have to be machined on the inner lip to a larger bore. You can send it to a machine shop or just use a die grinder." So I guess I am expected by them to make this modification if I want to use the spacers Oh well.

cgsheen Posted October 24, 2017 Share Posted October 24, 2017 (edited) That's weak... Die grinder?? This isn't something new - early Z's have a large front hub. You can fit anything on the rears but the fronts can be a problem for modern spacers and wheels. Super disappointed that Zcardepot would screw you over like that...
