    I want to purchase a set of wheels that have been discontinued. I found the rear wheels that fit my 355, but the matching front wheels I found would have to be drilled to fit the bolt pattern.

    From my cursory web research it seems this is a fairly common procedure, but there are proponents and opponents to this process. Has anyone done this for their 355 or is experienced on this matter and wants to give me the pros and cons?

    thanks!

    If the hubs have no bolt holes in them it's fine to do

    Lot's of aftermarket wheel bolt patterns get finished locally at machine shops

    These wheels already have a 5 hole pattern drilled into them. So, the wheels would either have to be refilled, then drilled, or just drilled to accommodate the 355's pattern.

    I know it can be done. My question is, does anyone have first hand knowledge of potential risks or things that can go wrong? Or is it a perfectly normal, worry-free procedure?

    There are wheels called "uni lug" that have 8 to 10 holes built into them. They are the lest expensive wheels for folks to get "that look" that are rated for like 85 mph use.

    Under no circumstance I would do it on a high performance car or any car of mine
    Drilling can safely be done however closing a hole by welding will weaken it greatly where strength is needed.


    Be safe try to find some wheels you like that fit correctly Dr :)

    If the bolt pattern is not too off from the 5x108 but the center hub bore is teh size, you can buy the new bolts that have the swiveling heads. What this means is the the bolt stud will go into the wheel hub and teh swiveling head will adjust and allign itself to fully grab teh wheel. not ure where I have seen them but they do exist.

    I'd personally look in to seeing if I could use a spacer/adapter first before I refilled/drilled the wheel hubs. Get an adapter that goes from the 5x108mm ferrari pattern to whatever the wheels bolt pattern is.

    Thats a Uni Nut, Crager had them back in the 60's
    Nothing but problems with them busting up the bores. Had a big block camaro in the 70's and destroyed wheels

    Don't screw around with these. Either they are 1st time use - you are drilling out virgin material - or you get different wheels. Do you really want to tear around a high speed sweeper on a compromised wheel? Not me brother. ;)
