Can we use the regular CTS 5 lug hubs...?

the base CTS is 5x115 whereas the V2/camaro/vette stuff is 5x120.65. therefore the wheels and brakes would no longer work, but you need to machine the rotors (or hubs) anyway so drilling another set of holes at 5x115 would be easy. the good thing here is that there are way, way more wheel choices with that bolt pattern than 5x120.
however, i don't know if the CTS hubs bolt up the same way as the vette/xlr hubs do. there's only one way to find out. if this is an options i'd love to go that route since the 5x120 bolt pattern kind of pushes you towards really low offset wheels when you go wide since it's a BMW bolt pattern.
try it out. report back.

comparing numbers on rock auto for the timken bearings (V: HA590077, HA590082; CTS: 513186, 512223) the dimensions are exactly the same minus the stud count. the only thing that's different is the flange offset and it's 1.656 on the V versus 1.661 on the CTS....so the same.
why do these not fit again?

Wow, there ARE a ton of choices for that bolt pattern. Anyone know the offset needed or point me where to find it? ebay search shows +38mm and +35mm... http://www.ebay.com/sch/Wheels/43953...p2045573.m1684

5x115 is a pretty oddball size, only used by a small number of GM platforms. When I've searched in the past for wheel options for the V6 guys I found the selection was shitty.

Apparently quite a few Dodges and Toyotas, among others, use that bolt pattern. In any case, FWIW: there are 3600+ in 5x115 just in 18s... http://www.ebay.com/sch/i.html?_from...p2045573.m1684

Based on the database I use, 94 modern car models use 5x115 and 98 modern car models use 5x120. So it's almost a 50/50 split. Most domestic cars use 5x115 and most imports use 5x120. The important thing to look into is whether or not your preferred set of rotors and wheels are available in the bolt pattern you want.
Regardless of which you choose, things will be a lot easier with a 5-lug wheel hub. But based on my research, you'll find a lot better wheel bearing options (including the vaunted SKF X-Tracker), wheels, and rotors at the 5x115 size. The 5x115 wheel bearings are likely to be drop-in replacements (whereas the 5x120 will have to be machined), due to the wide availability of parts with the correct hub dimensions for our spindles and their use of passive speed sensors.

using 5x115 as your limiting factor instead of 5x114.3 for wheel is kind of naive. they both will fit an 5x114.3 is the most widely used bolt pattern for wheels across literally every wheel manufacturer.
even the manufacturers of the wheels consider 5x114.3/115 and 5x120/120.65 interchangeable.

confirmed. you can use base hubs and redrill rotors for the more appropriate 5x115/114.3 bolt pattern. i'll have to update my information in order to reflect that part interchangeability. they're 100% bolt in.
