    Can someone tell me what size wheel bolts my 1984 308 with factory wheels (actually Superformance Repo) require? The factory spare parts catalogue lists 2 different part numbers. Front and rear? HR Bolts lists 2 numbers also but not specifically for a 308. They list 60mm and 70mm lengths X M14x1.5. Do these sound like the correct bolts for a 308QV? If not what are the correct lengths? Thanks...

    Thanks for the link. It looks like 44mm fronts and 35mm for the rears might be what I need. I'll measure the hub/rotor and wheel tomorrow to be sure.

    Lou,
    The 16" QV wheels (as well as the replicas) use the standard bolts that are factory with the 14" wheels. Not sure what year your car is, but the factory bolts work. I don't know the lengths, but the fronts are a tad longer, not because of the wheels but because the front hub has a deeper hole before the bolt engages the threads.

    There lies my problem. The previous owner replaced the factory wheels with BBS RS wheels. In doing so he also replaced all the wheel bolts with studs and wheel nuts. Therefore I have no bolts but lots of nuts, so to speak.

    If someone hasn't already done so, or if someone doesn't post what size they actually are I will measure the wheels and hubs/rotor tomorrow. Thanks...

    *smiling*

    I have both setups for #22641....have never used the BBS studs..

    I also have a stock set of bolts for OEM wheels on #22127......not easy to find and d@mned expensive..if no one will sell you nice used ones I'd go with Hill Engineering repros......

    He'll know correct length or I can measure my loose ones...
