I am interested in installing hub centric adapters ( spacers) In searching the list it appears that widths of 15 to 20 mm are used. In some cases two spacers are 15 mm and two are 20 mm. My question, what size should I get? Are the fronts a different width than the rears?. Finally who should I purchase them from. I have a 2007 Vantage with front tires of 235/40/19 and rears of 275/35/19 on stock wheels.

 

15mm front, 20mm rear..

Just get the right studs sent!

Look in the AM Classified section... several vendors too.
