What's up guys,I recently put on my lorinser wheels and I have 7mm spacers on them and I noticed that my lugs seem to be to short.
Can you guys recommend a shank size that would go perfect for the 7mm spacer?thanks

That's not something you buy based on recommendation. Its not childs play, There is a math to it to make sure your safe. You have to measure the thickness of your center bore from the out side of the lug hole to the back of the center bore/ wheel hub, then you add the width of the spacer to that number. After that you have to add additional length to accommodate for 6.5 minimum turns of the lug nut before it locks in to place and you can't tighten it anymore. You get those 3 nbers and you have your lug bolt size.

Well the rims offset is et38,fronts are 19x8.5 and the rears are 19x9.5.I fig that was enough to post knowing that many of us own clk with aftermarket wheels and also use spacers.

the offset is not an accurate measuring point because every wheel company makes their holes at different thicknesses which means some the lugs sit deeper in and some they sit further out. you cant make a guess it by the offset, you have to take it to a wheel shop to measure it or try diiffernt lug bolts and see which one fits best.

A good place to start is 28mm and go from there. Add the 7mm for the spacers and you'd need a 35mm shank length.

But like Ash said, have a wheel shop verify you have enough thread engagement before spending too much time on those lugs.
