Re: 2009+ CTS-V brake upgrade

On the backing plate there is (was in ur case) the center ring that slides over the knuckle of the spindle. It centers itself on the spindle and u bolt it down. Well I was referring to just the center section that "protects" the back of the hub from debris and road grime. My thought was to cut just the center off the backing plate and reuse it for extra protection. I'm not sure that I trust just that little rubber lip on the back to protect the bearings.

I will try and get some pics up this weekend for you on my setup. I went thru and replaced all steering components, swapped in poly bushings on the a-arms and sway bar. Then I blasted and undercoated the a-arms, when I get back home from ur neck of the woods, I will remount the a-arms, install Moog constant rate springs, get the spindle back on and try to complete the rest of the brake job.

I think I know what you mean. Honestly I am typically all about overbuilding stuff. But not having the dust shield does not concern me at all. The hub seal is designed specifically to keep crud out of the bearings. I have run my Wilwood brakes for about 2 years now (probably 3k miles). About a week a ago I pulled the hubs apart and everything is CLEAN. Looks brand new. Still I'm sure it wouldn't hurt to keep it. I look forward to seeing the pictures.

Go here to see my small build progress on my brake setup. Start from post #10 and work your way down.

Re: 2009+ CTS-V brake upgrade

That is looking good. Do you happen to have pictures of the wheels? I always like to see 19's on these cars.

Also, I'm sure that wasn't a final install picture, but you have your one caliper on the wrong side.

Re: 2009+ CTS-V brake upgrade

Thank you. Pics of the actual.wheel is coming this weekend.. similiar to yours. As for the caliper being on the wrong side, I pulled the lines and fittings off when they were powdercoated. I put them back on the wrong.ends of.the caliper. I fixed them already. When I get back hopefully I can get the wheels on for a few shots.

Re: 2009+ CTS-V brake upgrade

Got one rear bracket done. Needed a little bit of rework, but should be good to go.

Re: 2009+ CTS-V brake upgrade

You can't have too much brakes - in terms of piston count, pad size, and rotor size; that is for darn sure.

I actually have a set of Ed's brackets for the 9 bolt and CTS-V / 2010+ SS calipers. No e-brake though. Let me know if I can help.

Yeah, school has really killed my progress this year. Fortunately that is done for the summer next week. Going back to school while working was a bad idea.

I am hoping to run Silverstate this year, but stuff keeps coming up and I have a lot of projects to finish.

It is for the CTS/Camaro 14.5" rotor.

Re: 2009+ CTS-V brake upgrade

The CTS-V uses 14.5 but I'm pretty sure the Camaro and others used the 14".. are you 100% certain?

I recreated it in Catia a few months ago. PM me your email address and I can send you a .stp or .igs file that should work in Solidworks. I would print it out 1:1 first on paper, just to make sure everything looks correct.

Again, for everyone's sake, this is for the 9 bolt only. Right click "view image" for larger version.

Got my first front bracket today. Looks like it fits nice. 3/8" steel is chunky.

Ur set up is coming along very nicely. I would gladly like some help with devising a e-brake setup for my 9 bolt. It sucks when u are so used to pulling it after you park or on hills and now its no longer avail.

In the mean time, the car is back together.. Heres a couple shots i took today. Front and rear

Wow, the car looks great. Are those 19's? What wheels?

So you are using the 2010 SS rear calipers and rotors? And want to add the e-brake?

Great looking wheels. I remember looking at them last year and concluding I didn't like them. The problem is all the pictures on Bonspeed's website are of fully polished wheels. Yours look MUCH better with the gunmetal centers. Good job.

Regarding the 9 bolt. The 9 bolt bracket should be very similar to my 10/12 bolt bracket. The 9 bolt flange is pretty similar. I happen to have a 9 bolt laying around. I'll see if I can work something up this weekend.

Dude, u are awesome!! Thanks a million. I felt the same about their website. And although I was originally looking at HREs in the same style, the price diff was about 250 a wheel. So I took a chance. I'm happy with the outcome.

Sorry about the delay. I was working on a set of brackets for someone else with a ford differential. I should have some time this week to take a look at the 9 bolt.

Re: 2009+ CTS-V brake upgrade

No worries John. You are doin a favor for me, I'm not gonna rush you to get it done. Gives me a lil time to gather a few small parts needed to complete the upgrade when u actually have it done and ready to go. Thanks again for ur generosity in offering to fab up something for me.

Hi, where did you get front rotors, do you have part numbers, and how much were they.

Thx Doug

Rotors are from:

They are OEM Cadillac rotors with slots machined in them. They are $214 each from amazon.

Finally got all my diff issues sorted out. Here is the diff fully assembled with the brake components. Hoping to get brake lines bent up this weekend.

Re: 2009+ CTS-V brake upgrade

Hi again folks.

A local shop I do a lot of business with is turning a 2011 CTS-V into a track only car. They are upgrading the brakes on this car front and rear and are looking to sell the stock brakes. This car has only 6000 miles on it. Their are looking to get $1100 for everything. I think that is a great price and wanted to see if anyone here wanted them.

My cost matrix shows the retail price on all the parts to be $2209 if you shop around for the best prices.

Let me know if anyone is interested.

John, question is - what are they going to upgrade the brakes to? They are pretty stout stock...

I know it sounds crazy. They are upgrading to a Brembo GT kit. Basically the same caliper size class as the stock CTS-V but I believe they are a billet machined caliper vs the stock cast caliper.

I wonder if it will use the same 405mm (16") rotor as the Camaro SS kit!

It is crazy - anything that size is just a lot of weight to swing around, plus they will never be able to get enough tire under it to make it work optimally...

Agreed. Especially since they reduced weight on the car by 500lbs.

Re: 2009+ CTS-V brake upgrade

Well, I think I'm going insane. Picked up a Corvette ZR1 caliper to play around with for testing some brake kits, see the link below. Anyway, of course I slapped them inside my wheel and fell in love. I don't have the carbon rotor as they are big money, but this is where the caliper would mount with the 15.5" rotor.

Weather is bad, so only crappy indoor photos so far.

Re: 2009+ CTS-V brake upgrade

For more information, the ZR1 caliper is very similar to the gen II CTS-V caliper. It is about 1.5" longer caliper body than the CTS-V. And of course it has the Vette mounting lugs.

Notice the piston radiators. Very cool.

Re: 2009+ CTS-V brake upgrade

Man those ZR1 and CTV gen II calipers are super sexy!!! My mind is spinning thinking of the brakes I could have LOL!

Got your email... Not sure if my phone replied or not. Its kinda flaky on sending emails.

I hope this was not all for looks ?

For looks ? What do you mean about that ?
I think it would be pretty functional setup not for looks anything above a 4 piston setup is overkill for a strictly street car but the more brakes the better IMO so bring it

Then again people would buy a fisker karma and think they have a supercar now that's just for looks

Hi Jet,

There are a few reasons for this setup. First and most importantly, this car gets tracked. I am a huge fan of low maintenance dual duty track/street use. While the kit is generally considered overkill for a 3500lb 3rd gen, it allows me to run a very friendly street pad on the track without needing to change pads when I get to the track. This also explains my obsession with lock wire and torque seal. It takes almost no time for me to nut and bolt my car before and after each track day. It is primarily a visual check. I am also a stickler for brake pedal feel. The feel of this kit should be exactly what I want, a moderate effort, short travel pedal.

You are correct about the limit of cars on street tires - you can get only so much braking power out of your tires (fronts mostly) and going to some crazy 6 piston 15" kit is not going to make your car stop faster. This is one reason why I advocate those going to 17" or larger wheels run a 275 front tire (or larger) for more braking power - a 245-45-17 tire offers no more braking than a 245-50-16 sized one...

But as John said, on the track, larger kits do offer some advantages in terms of pads and also thermal radiation. But then you have cost and wheel size considerations to accomodate...
