Chris Wilson Posted May 6, 2014 Share Posted May 6, 2014 Looks like there is already a ring stuck on the wheel hub in the photo. I have to say this, proper wheels do not use spigot rings, some serious forces are transmitted from the wheel into the nose on the hub, and the fitment is critical for wheel concentricity. You will never EVER see OE rims that use rings to match the wrong bore size rim to the hub. For that reason there's a huge number of cars around that have odd issues with steering shake, premature damper failure, and strange tyre wear issues.

gt4tosupra Posted May 6, 2014 Author Share Posted May 6, 2014 Cheers Chris. I know what u mean about the right size being best of course. But these wheels are really nice and I got them at a real good price . Thing is, when I first got them I used the flat nuts, and got real bad vibration. I then got cone nuts and it's much much better but still not perfect. Wheels have been balanced btw. I'll check if that is a spigot then. If so it's come off the wheel, as this was a std car before. From my pics I was wondering why the centre bore of the wheel slopes in from about 70mm to about 60 ? Quote Link to comment Share on other sites More sharing options...
gt4tosupra Posted May 6, 2014 Author Share Posted May 6, 2014 Ok that isn't a spigot, it's just a build up of copper grease from the way the wheel sits. The wheel I'm sure now doesn't need spigots, they only move in a circular motion, not up or down or left to right.So I'm thinking now it must be looseness in my suspension bushes, being highlighted by the bigger wheels and offset?

Chris Wilson Posted May 6, 2014 Share Posted May 6, 2014 Vibration as such is nearly always caused by wheel or tyre imbalance, a buckled rim, a bulge on a tyre, or a wheel that is not running concentric to the hub bearing. I would suggest you concentrate the efforts there, before looking at suspension bushes. A dead, or near dead damper will allow even slight imbalance to be felt far more strongly at certain road speeds. Does the car vibrate at given and repeatable road speeds?

Chris cheers, that's very helpful. yes it seems to vibrate at 85+, and I haven't taken it over the ton. Now that's interesting when u say about knackered shocks, as in the other thread I started, I have removed this As it is allowing the rear passenger side tyre to touch the arch on bumps in the road, but the driver side is fine.

Chris Wilson Posted May 6, 2014 Share Posted May 6, 2014 It doesn't appear to have been leaking, but it's certainly not an OE type. Have you got the original rims and some usable tyres on them? that's always the ultimate check, put OE wheels and tyres back on, if the problem goes you know EXACTLY where to look Quote Link to comment Share on other sites More sharing options...
gt4tosupra Posted May 6, 2014 Author Share Posted May 6, 2014 Right I'll do that Chris. Swap two fronts first and go for drive, then do two rears. Suspension is kyb btw Quote Link to comment Share on other sites More sharing options...
Nic Posted May 6, 2014 Share Posted May 6, 2014 Ok that isn't a spigot, it's just a build up of copper grease from the way the wheel sits. Are you sure that's not a spigot ring fitted in the wheel? Quote Link to comment Share on other sites More sharing options...

garethr Posted May 7, 2014 Share Posted May 7, 2014 ...From my pics I was wondering why the centre bore of the wheel slopes in from about 70mm to about 60?The chamfer makes it easier to locate the wheel on the hub spigot. Quote Link to comment Share on other sites More sharing options...
