Rear Brake total weight savings is 3 lbs per wheel. -4lbs rotating weight from the Carbon Ceramic 380mm (15") rotor, and +1 lb for the larger ZR1 caliper, brake pads, pins etc.

-6 lbs total weight loss for the rears.

Stock iron rotor was 20.16lbs, the Brembo CC 16.16 lbs. Can't find the picture right now, but is is exactly 4 lbs lighter and much larger.






The front stock rotors are suppossed to be 26 lbs. The ZR1s will likely be around 18lbs each since they are slightly larger 394mm (15.5") than the rears. That should save 8lbs per side, with a loss of maybe 1lb for the larger calipers or a net loss of 14 lbs in the front.

This is estimated until we get the parts in. If my calculations (estimates) are right, that will be a total weight savings of 20 lbs front and rear, with 16 lbs of rotating weight.

The front wheels and tires are -4 lbs lighter than stock, and rear wheels and tires +2 lbs heavier due to the larger wheel/tire combo. Front and rear tires are all much lighter than the stock run flats.

Front wheels are 21 lbs each. 26 for the rears.

The caliper bolts weigh in at .38lbs for the pair. We'll be shaving off 56% of the weight of many of the stock bolts with titanium replacements soon.

We'll have Titanium Kits that will work on all applications.

You took 20 pounds off the Air Bag Switch Actuator? Now we know that you are truly committed. Or at least, should be!!! Like they say, when you are out of horsepower or traction, the only way to boost performance is to reduce the mass. This is getting good.

Jim - are you still running the Meziere Electric Water Pump? If so how much weight did it add / save?

fperra

OK, I give, what's the weight savings with the pretty Ti bolts? I'm guessing about 2 lbs total. Do thry work with Brembos?

Halltech

No, it is for sale.

Halltech

I don't know. If the stock caliper bolt are used (14mmX2.0X45) then yes.

They work with my Brembo ZR1 calipers.

Bolted the front ZR1 caliper on tonight. Fits perfectly.

So far, the ZR1 Brake system is a bolt on to the stock Z06 hubs and caliper mounts.

I cannot imagine any reason why they would not be a perfect setup for the Z06. I am looking forward to these babies stopping a 2900 lb Z06.

The 8 bolts save under 1 lbs. You have to lose you marbles to buy them according to Jason. That's is probably true, but in the end when you hunt for lbs. this is what it takes.

The pricing is $299 for all four brakes. Not cheap.

We did a weigh in on the stock rotor tonight. 26 lbs with 9200 miles on it. The ZR1 front rotors should be just under 17 lbs each.

The rear rotor, off the car was 9.6 lbs, with about 1/2 the pad left. 10 lbs easy with new pads.

What happened?? If you don't mind me asking.

Do you already have a zr1 roof/halo? I think I heard its 7 pounds lighter or so.
Also, do you find that your car runs hot or cold? I ask because I assume that, because your car runs on ethanol, it might run significantly cooler. On the other hand, you are making alot of power...Anyways what I'm getting at: smallest front radiator you need to dissipate the engines heat. Not only that, but its way up there in the front.

For the record, Caravaggio Race Seats will save you 30 lbs for the pair.

This is gunna be interesting because currently, per my accounting, I've got around 70 lbs of savings beyond what Jim's done to this point, and with a half tank of gas my '06 came in at 2935. So keep up the great work Jim because I'm dying to see how to get a Z06 under 2900 lbs.

Cheers, Paul.

PS. The Meziere EWP with ADD 5 lbs compared to the stock.

Gotcha

It has been posted that the front ZR1 rotors weigh 13 lbs each

Do you mean the rear caliper was 9.6 lbs?

Halltech

The front rotors will be close to 17 lbs each, not 13. Our scale is a certified scale, and is very accurate, to the 1/100 of a lb.

The rear 15" weighed 16.16 lbs, so I doubt that the 15.5" rotor for the front would weigh 3 lbs less. We should have the front rotors this week, possible today. They were not in Lansing, MI, so a search is underway.

Finished the rear calipers/rotors yesterday, waiting for our Titanium Caliper Mount Bolts to finish (Thursday), and mounted the front ZR1 caliper last night. Perfect fit.

We will be selling complete bolt on ZR1 Brake Systems for the Z06 soon, which will include the titanium caliper mount bolts (8 per set) and have optional titanium bleed screws for cool, not weight.

Yes, the 9.6 lbs was the stock rear caliper weight, but the pads are down 50%, so 10 lbs per caliper is right on the money with new pads.

How much is your kit going to possibly run? It doesnt have to be exact, just want to know how much to set off to the side when it is available. Thanks

That may happen, but it will be painted. I do not like the two tone look of the roof on anything but the Cyber Gray color.

We'll have the hood, top, and something else by this Fall.

Halltech

Weighs too much. Voids the Katech Engine Warranty.

Painrace

I hope you can feel 1#! at $299 a pound that is $5,980 per 20 pounds loss. Even us dumb A** racers can't afford that.

GREAT Thread and project. I look forward to seeing what is new every day. I can't wait to see it at Track Attack. By June it may weigh 1,500 pounds and Debbie will still ride in it!

Jim

Gotcha

The front rotors dont have to accomodate a parking brake, so they should weigh less than the rears...

If the ZR1 front rotors weigh 17 lbs, they will be heavier than the AFX 2 piece Z06 rotor which weigh 16.25 lbs

Anyway, cool project on a top shelf car

What wheels will you be running?
