porsche adaptors...

following on from my experience with the AA a while back where one of my 4x100-5x130 adaptors came loose from the hub.

IT HAS HAPPENED AGAIN.

i was giving it some beans around denbigh way this evening, brakes and tyres nice and warm lol - when i hear a clattering.

im not overly confident with the old adaptors of late so jacked it up and found the wheel loose again, this was after progressively tightening (diagonally) with the use of a 1.5 foot bar.

rather pissed off, i think it has something to do with the thermal exapansion of ally compared to the material of the disc/hub and adaptor retaining bolt material.

anyone ever heard of similar.

i was thinking about the power and the way it was used but i discounted that as a factor

I had the same experiance mate, i got my adaptors turned down to 16mm wide to fit my crazy offset BBS's. I had the clattering sound and my wheel had started to come loose.
I had put it down to me not possible tightening them enough (i was not concentrating at the time) but i guess it could be the ally properties of the adaptors.

How wide are your adaptors?

how old are they? Maybe the threads have got worn as the steel will probably wear them down a bit.

I am looking to get wider adaptors after i get arch work done as it might give me a bit more confidence.

the adaptors are new (well were new) its the bolts from adaptor to hub - in just guessing they are shiznit to be honest

Yea that's not what happened to mine, what brand are they?

FK, the bolts that hold them to the hub are not conical or radiused.

poor design i think - i may contersink them and turn some tapered washers - but am seriously thinking about loosing the whole porsche wheel idea

Mine are FK too, that sounds a bit strange. Maybe the porshe type are different.

thinking about some compomotive whee;s

which ones?

the 5 spoke ones, just waiting on the pics off a guy - track slaggieness, get rid of the number plate and jobs a good un

i quite like those rims on it ant, it stands the car out for me

yeah but safety is high on my agenda.

we will see how they adhere over the next week, may try some thread lock

compomotive mo's????? i might think about swappin the turbines for them

you wish ha ha ha..

its blue n its called threadlocker

or just copper grease

the colour depends on the manufacturer and strength of the locking compound - something i have already discussed above^

what benefit will an anti seize compound be, im quite intrigued?



its definetly down to the type of hole used on the adaptor retaining bolts (i.e no conical or radius) and the thermal properties of the dissimilar materials used in the hub/disc/wheel & adaptor..

dangerous i think to be fair.

were the actual wheel bolts screwd into ally? or was there a steel insert to screw into,

The adaptors ive made in the past have always been stainless, ally just isnt a good idea to bolt wheels onto, i'ts never gona be as strong as steel or stainless and also a good chance of cross threading, but mabing getting some steel inserts made to fit the adaptors might solve ur problem

no the wheel to adaptor bolts are not helicoiled (fk brand - TUV approved)

the bolts that keep on loosening are the adaptor to hub.

i did have steel adaptors before but they were poo, they added massive amounts of weight to the axle and thus affected the cars performance and wheel balance.
