An engineer at work is selling his honda alloys which have a Honda centre cap which is about 2" wide in all 4 alloys, im pretty sore these can come out and can be replaced, im just wondering before i buy, would my local fiat dealer or somewhere on the web is there any sort of fiat alloy centre caps i can buy?

cheers

can get from dealer, but thats the least of your worried, pcd, center bore an offset comes first

first of all, i thought they just popped out and what does pcd, center bore an offset mean?
Im not uptodate on my jargon

they do just pop out, but different car manufacturers attach wheels to their cars differently... for example Fiat use a 4 stud pattern (4 bolts) whereas others use 5 etc. your PCD is the spacing between them, so Fiats are mainly 98 or 100 (the 2mm difference can be solved with things called wobbly bolts) whereas another manufacturer may have a PCD of 110..

Therefore you can only get alloys that are made for Fiats to fit your fiat. Hope that helps

actually the centre caps are just round and dont cover the studs, ive just fitted one alloy to my car and the centre cap is about as bigg as the inside of a CD, ill take apic and post

no i dont think you understand, the wheels wont be sitting dead center as they dont have a pcd of 98mm or a center hole size of 58.1mm and will rub on inner wing if off set is too great

ive tried these alloys on my car and they dont rub on full lock and opposite full lock which is good. here is a pic of these alloys.

Just because they don't rub on full lock doesn't mean they are safely fitted, the centre bore will most likely be wrong on them so all the weight of the car will be on the bolts instead of the lip that protrudes from the hub, this is dangerous and it means they could fall off.

Also if the centre bore is wrong they won't be sitting on the hubs dead centre which again is dangerous.

o thanks for the word of warning. i fell like a right numpty now sorry for being one.
my offset is positive i think, but i dont know how much, ill go check the measurement between the studs

its 100mm for the measurement of where the nuts go and i have a 40mm offset, these measurements are off my new alloys, my centre bore on the steel wheels is 58mm (hard measuring from a tape measure as my metal measuring tool was too bid to fit inside) and the alloy is 62mm (not that accurate again off a tape measure). is there such a thing like a 4mm ring i could get to put onto the alloys to take the strain off the nuts and i would have to get wobbly nuts

I've just looked on Google and it looks like Honda wheels are 4x100mm PCD and the centre bore is 64mm.

FIAT uses a PCD of 4x98mm and a centre bore of 58.1mm, therefore you will need wobbly bolts (aka variable PCD bolts) and a set of 5.9mm spigot rings, any alloy wheel shop should sell these spigot rings.

I think the offset of standard Honda alloy wheels is 38, this should be fine so no spacers should be required.

Hope that helps.

yeh thanks rockbottom, tris and dave for your help towards me the numpty, ill go into my local halfords and see if they do the spigot rings

ive found some spigot rings which are 58.1 - 63.4mm coz they are 0.6mm out will that affect the positioning that much its a danger to drive?

I wouldn't risk it, try contacting http://www.performancealloys.com/orings.asp

They should be able to supply spigot rings in the exact size you need.

performancealloys suck though, must be some where else

I've found them to be alright, just a bit overpriced.

Guess you could try http://cgi.ebay.co.uk/SPIGOT-RINGS-...yZ122154QQssPageNameZWDVWQQrdZ1QQcmdZViewItem never used these people before though.
