Anyone know of any 4/2 Piston Caliper sets for the G8 on the market, either off another car or for the G8 specifically?

I'd like to buy the car buy brakes are very important to me, Brembo or AP Racing 4/2, etc. setup is a must on a car this heavy.

Holden Commodore SS?? I'm sure they have them for that as it's been out about 2 years now. :)

The standard brakes on the G8 are "World Class" according to some of those who tested the car during it's debut. 60 to 0 was like 109 feet. That by itself is incredible! And that from a car that is 2 tons! What more can we ask for? You can compare those numbers to just about any performance import (BMW, Merc...etc). You would be wasting your money replacing the brakes for anything less that all out racing, IMHO.

I am a race car driver actually. Road race to be specific, so brakes are of the utmost importance to me.

Pete Basica tested his Pedderized Extreme package G8 woth a blower on it today. The brakes were the weak link. OEM rotors looked like the sun, and pads began to fail.

AP brakes in Au are available with a $8k price tag.

Mike Haddad, at Haddad Motorsports is having his G8 test fitted as I type for 6 pisotn calipers in the front and unkown size in the rear.

DBA brake guys are off in left field, and do not know where they are at or what they are doiing in the USA.

So right know brake upgrades are seriously limited

Pete had some major brake fade after 3-4 laps on OE brakes. So tracking your G8 on OE brakes are a major challenge

I take it the CTSV Brembos do not bolt up to the knuckles on the G8? Has anyone tried?

Does anyone know of the Brembos for the GXP will bolt to the G8GT Knuckles?

This will likely be the best bet for folks who use brakes.

Out of curiosity, what track was Pete running? OE Pads? OE Rotors?

I REally do not know which track. It is in the Detroit area, and they run a monthly opne track 1 time a month there. Hopefully Pete will bounce in.

I bet the GXP brakes which are practically identical to Camaro SS brakes (except for rears) will bolt right on same knuckles as GT in front.

I'm not sure, the CTSV brakes won't bolt onto the std CTS Knuckles so it's possible that the GXP uses upgraded knuckles (possibly larger bearings, etc)

Hi Mike,
I'm not sure what you are talking about. Because direct replacement dba rotors not only have been finalized, but have already been shipped to the US. And they also do work on larger rotors/calipers brake upgrade.

I suspect the knuckle on the Camaro will be different than the knuckle on the G8 :wink2:

After running some hot laps at Gingerman, the G8 does need a brake upgrade. Going into the back straight you carry good speed into and out of the straight. That straight leads into a hard right... and a wall / guard rail. Late braking and triple digits don't work with the G8. Good thing they have an entrance into the pits off to the left...

Drive the car before you decide to spend money replacing brakes that are already great.

Spend your money on a Roto Fab CAI, lowering springs, an engine tune, catback, headers or something else, IMO.

My car is at Baer brakes right now. They are setting up a nice brake system for the car. I don't know all the details quite yet.

What I do know is that the front is going to be a 6 piston caliper with at the minimum a 14" two piece rotor.

They are also setting up the rear but I'm not sure what direction we are going with there.

Baer products have treated me exceptionally well over the years in quite of few of my race cars and customer cars. They are 100% made in the USA and they don't price gouge as do others.

I will have more details over the next 2 weeks as for price, availability, and details on the system.

Thanks

I just e-mailed a friend in the industry who told me he was going to put together a GXP brake kit for the G8GT once he has pricing. He has access to all the parts books and compares the part number of the 2 systems to see what is the same (knuckles?) and what is different. hopefully he will have some answers that might help.

What pads and fluid were you using? I would bet a good set of track pads and some high temp brake fluid would make a world of difference.

As you should know, DBA is the distributor for AP brakes. The price for a set of larger calipers, rotors, pads and lines, were $8K, not counting shipping.

That is a ridiculus price. And you are correct, the entire DBA organizatin, here and in Au, do not have a grip on reality and are lost

Stainless lines, I think it was Motul fluid with stock pads.

I don’t know where you get your info but it is not even close to reality

Since official pricing is not released for G8 – VE I’ll just do comparison for GTO

Baer Claw Big Brake System - 6-Piston MSPR $3527 + SHIPPING and FRONT ONLY

HSV / AP-6 Piston LARGE GTS BRAKE KIT $6400 FRONT AND REAR INCLUDES SHIPPING

I do things in the proper order, at least the proper order for someone who drives their car through the twisties, and on road courses...

Tires, Brakes, Suspension.

Lots of driver training.

Some more Tires, brakes, Suspension.

Then and only then things that give more power.

If you can brake later, harder, you don't need to add power to your car to get a faster lap time.

Hee Hee. I run Watkins Glen, the blue-bushes there are fun too.

I tagged the wall at summit point with my racecar going down the carosel ever so gently. Just backed it into the tire wall at like 2mph, but it felt like a lot more!

Nice nice. Although 4800 seems a little steep, I'd imagine after the initial sales we'll see it drop a bit.

Chatted with the guys at BAER this morning. All is going well. They are using their new 6 piston caliper and 14 inch rotors. The normal sets will come drille, slotted and plated. But if you are going to road race, they still recommend no drilling of the rotors, which they can do.

their rotors will come with hats for lighter weight.

Hopefully, Mike will get his G8 back next week if all the stars and moon line up correctly.LOL

This is BAERS new generation brakes.

My guy there says they are getting lots of calls on them, since we have been chatting about them on this forum. So they are now really excited because they can realize the market potential

thanks

Guys, the Harrop brakes have worked extremely well on the GTO, and are great quality. So it will be great to very soon have multiple choices in brakes for the G8 and soon to be Camaro
