Currently i would clear the 4 piston caliper if the measurement is 1.37 inches. But who the hell wants a 4 piston when you can have the 6 piston. Hope this helps. Now anyone with offsets of +38 should be fine on their G sedans. Dave do I at least get a discount for all the hard work?

Hey, I'm going to get the 4 piston caliper! Seriously 4-piston is plenty even for my tracking duties. Good work and your investigation just confirms the work I did with my wheels. Remember, the most important thing is the offset AND the spoke design.

I just finished measuring against my 5Zigen FN01R-C 17x8 +43 wheel. The 4-piston caliper will fit with 3-4 mm of clearance. As suspected the 6-piston caliper will touch. The 6 piston or 4 piston will fit with my +38 wheel.

Looks like the 4piston front is more affordable still!! How does the CALIPER look for the 4piston... Dave do you have any shots of the 4piston fronts? Are teh rotors small and the caliper smaller than the 6 piston?

The only difference between the 6pot kit and the 4 pot kit is the calipers. Everything else is the same including the rotors. The 4-pot caliper is the Forged Billet Superlite. This caliper is forged whereas the 6 pot is not. The 4 pot caliper is a bit smaller in dimension. Look here for a pic and a lot of info.

19" oems

Dave said the coupe wheels looked like they had enough room. Does anyone know for sure if the 6 piston will clear the 19" oems? I have the wheels on an 03 5AT Coupe.

Thanks,

Les

If your Offset is +38 on those wheels, you will be fine.

Offsets

Can anyone verify if the OEM 19's are 30mm offset on the fronts and 33mm offset on the rears? I read that on the fresh alloy site.

I know squat about offset and what they mean, if these numbers are correct, will the OEM 19 clear the Wilwood 6 piston caliper?

G35Sedan, how does a 30mm and 33mm offset compare to the +38 offset you mentioned?

Thanks,

Les

Les,
I could write a lot, but here's this link that can help you understand it. http://www.discountedwheelwarehouse....ment_Guide.cfm
Hope this helps you.

Went to that link thanks.

So if I understand correctly, a wheel with a 30 or 33 mm offset has the hub mounting surface closer to the wheel center than the 38 mm offset which you mention.

Also, those wheels that have a deep lip tend to have a negative offset and would definitely have problems with the Wilwood caliper.

So....if the 19" oem wheels for the coupe only has the above mentioned offsets, they won't clear the caliper???

Did I screw that up totally????

the more i learn about brakes, the more i worry about brake bias if
i just upgrade front bbk only. Either upgrade rotors, pads only or upgrade
both front and rear BBK

That's not entirely true. Stoptech makes the overall piston surface area equal or smaller to the OEM piston surface area to offset the bias of the larger rotor with their front kits. There are ways to maintain or even reduce the factory bias with only a front kit.

Can we order different ROTORS from ARIZONAZCAR? Like maybe DRILLED vs. SLOTTED?

I spoke with dave on Friday and asked the same question. He is not a big supporter of drilled rotors, he has his reasons for it, mainly rotor life. i'm sure he has the means to do it, but he prefers to sell slotted rotors due to all the research he has done comparing slotted vs drilled. Send him an email or call him.

Okay, sorry to bring back an old post but I think that this is a very informative post.

I think that I am definitely going to purchase the ARIZONAZCAR'S six-piston caliper BBK. I just have a question.

My wheels are 19x8 with a +40 offset. I just called and confirmed with the wheel company. I measured it from rotor hat and it measured 1.6 inches. I also measured from the caliper surface and that measured like 1.1 inches.

Am I going to need a wheel spacer and if so what wheel spacer should I go with?

Well looking back at post #54 of this thread by Dave, he said you need approximately 1.5 inches from the rotor hat to the inside of the wheel spokes for the 6-pot caliper. So sounds like your fine. At the worst you'll probably need like a 2-3 mm spacer. I bought myself a set of spacers that are about 1.15 mm just in case my 4-pot kit didn't fit but ended up not needing them. With a small spacer like that longer wheel studs aren't necessary.
