hi guys, i just bought a 2000 silverado 1500 2wd rcsb. i am about to buy a new set of enkei rt6 wheels. before i do, i need to be able to pick between the two different bore diameters. here are the choices the enkei website gave me. 78 or 108 bore diameter? any info will help. thanks

the two different wheels posted on the enkei website
25229083SM 6 x 139.7 108

25229084SM 6 x 139.7 78

 

78mm bore
