Cadillac CTS-V - How wide can we go when widening stock V wheels?

I know a few members have done this and I'm considering having a pair widened myself. I'm assuming 10" is the max width in the rear? Anything else need to be done or changed to allow this to work?

I'd like to be able to run a 295/35 comfortably out back and have the wheel fill the wheel well nicely. I want to go as wide as possible without causing any clearance issues.

Thanks in advance fellas!

That's a good question I would like to run 305 or 315's im thinking of swapping hubs and running some C6 Zo6 wheels

I considered doing a 5-lug swap myself but I like the look of the stock wheels and don't really wanna mess with all that. A 315 would be nice but anything 295 or wider, I'd be happy.

You'll need 5mm spacers and different trailing arms. I posted a thread in the CF what i did to mine
I think anything more than 10" you'll run into problems, you'd definitely need a bigger spacer, then you would need longer wheel studs (with anything over a 5mm spacer)
Also any further out you'd probably rub the fenders even if rolled, if you are lowered.
I may have even posted a thread here on it too.
315's lowered forget about it.

Sounds like I'll just widen them to 10", run the 5mm spacer and swap trailing arms if needed and stick with a 295/35 or something like that so I can still lower it without any issues.

You still have to do some slight grinding here and there. My old thread covers it I'll try find it for ya.

Ok sweet! I rarely get on CF but i do have a membership there so that would be great. Thanks!! :cheers:

Appreciate it man! Thanks!

Call Eric Vaughn Machine in Monrovia ca.
He really knows alunimum wheel widening you won't see scabbed in sections
or poor quality welds he does it right and usually less than $500 pair

Ok, I'll give him a shout. I was told $150 a wheel initially but I want a quality job.

On their site they say they cant do steel wheels. Mine are chrome, does that mean they are steel? I didnt think you could chrome aluminum
