iv just seen these spacers on ebay which can be used to convert 4stud wheel hubs to 5stud??? is this possibale??

yes like my 5 stud porsche wheels to 4 stud ibiza.
but the spacers are about 20mm thick which means the wheels will stick out 20mm further catching on the arches you need and offset of about 50 to allow the 20mm spacers to be used.
also dont buy cheep **** spacers as you get wheel wobble like crazy. get good fk ones aorund £200 a set
 
by time you get the 20mm adaptors on they will be an offaset of about 18 and will stick out past the front arch by a mile and look stupid. plus by time you've got the adaptors at about £200 (yes you can get them for about £100 but they give alot of wheel wobble and are really heavy, the fk ones weigh next to nothing)
 
Ye but will these alloys fit the reason i want them is because there local 10mins max! these alloys are just for time being intill can afford abit more money.
 
so these alloys wont fit!

It says offset without spacers is 38? So I would think they would. If not get the right size spacers.

Or if your worried, ring a wheel dealer and make out your intrested in buying wheels from them and confirm what offset you need. If they confirm they are 38 then I would imagine they will fit.
