[s-cars] Donkeyitis - A tale of luck and lug bolt laxity

[Joan & Paul]

Ed,

I just bought my wheel bolts from ECS Tuning.  My after-market Milli Miglias required longer bolts - 35mm in length compared to the stock 25mm.  They run about $2.25 each.  ECS Also has different sizes - 32mm, 40mm, and I'm not sure what other sizes.  There is also a place in Washington that I came across on the web that has a great selection of bolts for the URS but I can't remember their url - :(

HTH
Paul
95 S6 (mit longer wheel bolts in the summer)
