Audi RS5 2019 with 15mm spacers?
 

Hello,

I had bought a 2019 RS5 with spacers installed (spacers are 15mm, 3.5x45), the problem is that the lug nuts are stock, I believe they are 33mm to 38mm or something like that.
For a reason I know that I need M14 x 1.5 with a 48 mm or 55mm but I am not sure which one I need exactly.
Is there anyone who could guide me throughout choosing the right ones ?

thank you in advance, I will post some pictures with the lug nuts and the spacers.

Thank you !

you need a wheel bolt that has 15mm more thread length on it than a stock one if you have 15mm spacers. end of story. measure the length, then add 15mm and call it a day. hope this helps. what you have right now is definitely unsafe to be driving around on.

Stock wheel bolts are 27mm (measured from the seat to end of threads; not the total bolt length). As mhoran89 stated, add the spacer length to the stock bolt length. With 15mm spacers you'll theoretically need 42mm bolts (14x1.5x42mm). You can double check bolt length by going to ECStuning and checking out the length of the wheel bolts they include in their 15mm spacer kits. It looks like they include 45mm bolts (likely because they don't sell 42mm bolts). A few mm longer bolt is safer (as long as it doesn't hit the hub) than having too short of a bolt.

I have a 2019 RS5 SB with 12.5mm front and 15mm rear spacers. The 12.5mm spacers came with 40mm bolts and the 15mm spacers came with 45mm bolts.
