how many MM from the face of the wheel to the inside of the rim is a -28 offset?

by face i mean the bit that butts up agains the brake drums

we need to know how wide the rim is?

this breaks down the offset/backspacing thing:

Backspace Method: Measure from the extreme rear edge of the rim to the hub mounting face. Distance "A" in millimetres.

Centreline Method: Measure the overall width of rim (Distance “X”), halve this measurement to find centreline then measure backspace (Distance “A”).

Subtract “A” from “X/2” and you now have the centreline offset, which in Australia is written 35P or 10N to denote either positive or negative centreline offset. In Europe, centreline offset is usually written ET35 or ET-10 etc.

NOTE: The centreline offset measurement is “rim width dependant”, ie. as the width of the rim changes, so does the centreline offset, eg. if you have 14 x 6 wheels with 47P offset and would like to fit 14 x 7 alloys with the same backspace, then the same offset in 14 x 7 is 35P. In both instances, the backspace remains at 135mm.

fuck. i dont know how wide my rims are.

i got a measurement from the center of the tires and they are 53inchs or 1346mm.

give or take 10mm.

and fuck me it leaking oil again from the front seal! mm that would eplain why my brakes are being so shit lately. its driping from the inside of the brake disk gaurd thing onto the rim.

quick question on replacing the seal. the knuckle needs to come off doesnt it? which mean i need new swivel hiub felts?

ina seal no, just take off your wheel, then the caliper, then the 4 bolts and it should just be behind the CV

[brendan]

yup but to get the CV out need need the knuckle off dont you? im talking about the little tiny fucker that the axel slides into. and mounts into the diff housing

He`s on the money!!!

so knuckle stays on? Thank god. Need to replace wheel bears so works out good

your rims should have something like 15x7 jj stamped on them some where. once you know the width take one off put a flat edge on the back of the rim lip (300mm steel ruler) & measure down to the hub face & that will give you your back space measurement. from there you can work out the offset.

take some photo's of the rims, you might get lucky & someone might be able to see if they are 15x7's or 15x8's
