Alrite guys, I've got an 03 cts 5 lug and 06 cts v 6 lug. My cts v is sitting whilst rotors gather rust and it bothers me. So I was wondering if i can swap them and even the calipers if possible. How long will it take? Any modifications? Pros? Cons?

you will need to swap the hubs, rotors, and wheels but it will all fit and is a bolt on deal

Idahoctsv

Sweet, can I use the caliper too?

Yes, and you would kind of have to, since the stock V6 calipers aren't going to fit over the V rotors.

Idahoctsv

Hmm.. Yea didn't think that one through. Are there any brake lines I will need to add or change?

Wouldnt this be an epic downgrade in stopping power?

I think he wants to put the V stuff onto the non-V, since the V is just sitting.

Idahoctsv

Yea and then once I'm done building it I will either buy new ones or throw them back on.

The base CTS and the V share the same brake lines, however, there is a recall on the CTS lines and you my want to see if you are covered before the swap. Or you can inspect them yourself as well. There is a foam peice that covers the joint where the hose is crimped into the metal fitting that bolts to the caliper. This foam holds water and dirt and causes corrosion of the fitting and eventually the line will fail. This is a good idea on the V as well because for some reason the V was not included in the CTS brake line recall.

Doing a 5 lug swap can't be this easy or everyone would be doing it.

Just to clarify....you guys are saying you can bolt the CTS 5 lug hubs on the V1 then re-drill the V1 rotors, bolt the V1 caliper on and plug the abs connector in and everything works???

Then why is everyone using the corvette hubs??

Who said anything about re-drilling rotors? Of course you can't do that, you have to replace the rotors too.

Ok, which rotor do you use????

I believe what he is trying to do is take his cts v hubs, rotors and calipers and put them on his base cts. He is turning his base cts into a six lug, not his cts v into a 5 lug. Someone correct me if I'm wrong

That's what it sounds like to me.
You would use a 5 lug rotor that matches your caliper. Seems like a pretty simple swap to me.

Well.....it isn't. Do a search but it may be Camaro rotors but I think they have a different lug pattern than the cts 5 lug hubs are going to give you.

MrAkalin

Seems like a lot of work just cause you want V brakes on your base CTS while your V is out of commission

Why is it so hard? Yes, the CTS 5 lug hubs are different than Corvette/Camaro hubs so that combo wouldn't work. This guy is trying to swap out the entire set up so he won't have an issue. If you want 5 lug and want to keep your big brakes I would imagine you could switch to a Corvette hub/rotor, or to a new V setup. But I don't think the new V has the same pattern as the Vette/Camaro.

Misunderstood OP. direct swap all of it from the v to the cts.... Be ready to swap the spindle too

I think it comes down to wheel selection. The V6 CTS has a 5x115mm bolt pattern, which isn't terribly popular - basically, it's a GM passenger car/minivan bolt pattern. By using the Vette hubs you get bolt patterns with much better selection of wide 18/19/20" wheels. The Vette hubs also allow you to use already existing big rotors, whereas using the V6 CTS hubs would necessitate that you modify rotors to work with the 115mm bolt spacing. (With that said, you could probably put a 5x120mm rotor onto a 5x115mm hub without too much effort. The V2 rotors have lug holes sized to clear 14mm wheel studs, so there's a bit of extra slop to work with compared to the 12mm studs on the V6 CTS hubs.)

2 bolts for each caliper, 3 bolts for each hub. Bleed the brakes. Not very complicated at all.

No need - the spindles are the same.
