I am trying to decide on what brakes I am going to run, I have been looking at the KORE kits recently, I had it in my head that I was going to put Wilwoods 6 piston kit on the front untill I learned about the Kore kits. I have the C5 setup on both of my 4th gen F cars, they seem to work decent. I have a couple friends with Wilwood kits that I have driven, I really like the pedle feel of the Wilwood kits.....

I plan on running a 17" wheel either way, probably a torque thrust II or
simular so the brakes will be seen so looks will be a consideration.

I can have the 6 piston Wilwood kit for about the same cost as the KORE kit so cost really is a non Issue. Anyone have pro's or cons for either kit?

I installed a Kore3 kit (C5) on the front of my '66 convertible (i SOLD THE CAR IN 2007).

The kit was GREAT, a true "bolt-on", although, at the time Kore3 actually machined my hubs down, which I think they no longer do.

Kore3 also had GREAT customer service... I spoke directly to Tobin MANY times (both email and on the phone, mostly with questions BEFORE I purchased the kit). Always a quick response, always willing to listen and talk... Great product and a competative price... The kit was pretty much complete, and an easy bolt-on in my garage...

The only "con" I had, was that Kore3 did NOT offer a master cylinder with the kits (As I recall though, Tobin and I discussed what bore size I'd need, etc)

I wouldn't hesitate using Kore3 again...

One word of caution: I was using Vintage Wheel Works V40 wheels, and I had to run a thin spacer (~1/8") so the calipers would clear the back of the spokes. I didn't mind, but I know some people are totally against spacers. With the 17" rim, the caliper was also close to the barrel of the rim, but it cleared... Might be different with other wheel brands...

Spacer deal was the same on one of the Wilwood kits too, was supposed to clear a stock 17" SS wheel, it touched JUST enough to scrape the powdercoat off the calipers...I just chalked it up to aftermarket....

I have the older 4 piston Wilwood and use a standard master cylinder (1-1/8"). I have had them for 10 years, lots of track days (VERY heavy break use) and no problems. I had some spacer issues also, finally got new rims and got it all corrected however.
The first set of calipers were bad (real load squeal) but Wilwood replaced them under warranty, no charge. I have had to replace the rotors once, they were just used up, had a couple of hard spots etc.
I don't know about the Kore product.
I would buy Wilwood again.

I know the Wilwood stuff is good, I know the C5 stuff is proven..... I guess I am just looking at pro's and Cons..

C5 stuff pro,
I have some stuff already
parts avail almost everywhere.
Cheap

con?

Wilwood pro's
6 piston so maybe a little better feel
many pad options
Looks?

Con?
parts not as redily avail
there is a small added cost.

Are you planning on a hydroboost, too?

Kinda tough to do pros and cons since most guys would likely have one or the other. Pretty pricey to have tried both. I have Wilwoods - 6 piston in front and 4 piston in back all under 18" wheels. Teamed them with a Hydratech hydroboost and everything is working great! Stops like a new age sportscar. No rubbing or other issues.

I have no experience with the others.

Wow for me the waters keep getting more and more muddy! I was researching upgrading the front suspension and found the SC&C stuff, and then the AFX spindles, its really not that much more to get the AFX spindles over the Stage II kit, and then the C5 brake stuff seems like a no brainer as the C5 stuff bolts right on the AFX spindle! The cost can hardly be beat PLUS the AFX spindle gets the bump steer issue under control....

ARRRRRRRGGGGGGGHHHH!!!! :clonk:

So what do you run on the rear with C5 stuff on the front? I want to retain the ability to put a 15" wheel on the rear for some drag strip action as My car will be more "Pro Driver" than "Pro touring".
I have most of an LT1 rear disk kit and most of a LS1 Rear disk kit. I know you can get 15" drag wheels over LS1 stuff IF you grind on the calipers, wich I dunno if I wanna do. I assume 15" Wheels fit over LT1 rear brakes with no mods... Maybe that is the way to go....... choices, choices, choices!!!! :wacko:

Carnutz,

With the C5/ATX AFX Spindle setup up front I've kept the Baer EradiSpeed setup in the rear. I have not had the chance to go out with the car and balance anything yet due to the weather here in NJ...hopefully sometime in April. I believe the EradiSpeed rear brakes should be sufficient with the C5 setup. Anyone else care to comment?

I'm also running 17" wheels (Cragar SS) front and rear. Note that I had to add a 1/4" spacer to my front hubs in order to clear the larger C5 caliper when it compresses on the rotor. Also, be certain that when you do order the ATX AFX spindles to specify the stud, I did not know at the time and ended up with (If memory serves me correct) 1.5 X 12.5 mm. I ordered a set of lugs to match the studs and I was all set.

I stayed with the C5 calipers in the rear to match my fronts. I kind of liked the idea of a matching set - where emergency parts could be found at the local napa. It turns out that the calipers are a direct match to those installed on late model F-body cars, so they bolted right up to the backing plate. For your 70 they would fit without any parking lever mods, and since the rotors are only 12" - they should fit within the wheels you mentioned.

I know what your real dilema is. You have too many toys. Please send atleast 2 of them to me. It will help you, I promise. :D

I dont think they will, the LS1 camaro rear stuff needs the caliper ground smooth to clear 15" welds, I thought the C5 calipers were a tad bigger yet.... I cant say for sure but that is what I have been told. Hmmmmm

I can promise you they are not bigger - page through this post - I did a side by side comparison last year.

WOW that is cool! so the LS1 F car brakes are essentially the same as a C5 ??? Hmmm I have the C5 stuff on my 95 Bird and LS1 stuff on the rear, maybe Ill swap calipers in the spring so I can run all the same compound pads........How did you figure that out?

Is the stock brake "hang out" on a 70 Chevelle (stock 12 bolt drumbs) the same as the LS1 set up? Will LS1 rear backing plated bolt on with out mods or what is required to make them fit? Differnt axles required?

I had several sets of rear F-body setups (long story - just be careful when you tell 3-4 friends to be on the lookout for parts for you - sometimes they are all successful). I felt comfortable enough from research that the PBR LS1FBody/C5 calipers in the rear were the exact same dimensions that I ordered a full set of C5 Calipers and pads, more so they'd match - having them side by side proved it for sure.

the LS1 F body backing plate will mount to any year 12 bolt without mods. On the earlier (64-67) narrow 12 bolts, there is a clearance issue with the parking brake lever. That can be fixed in several ways. See http://www.chevelles.com/forums/showthread.php?t=215679

I'm sorry - I'm not sure what you mean by this - "Is the stock brake hang out on a 70 Chevelle the same as the LS1 set up?"

LOL Moser refers to the brake hang out as the distance from the end of the housing to flange of the axle, that dimention is important to know so your rotor is centered in the caliper "cage" or so your drumb properly engages the shoes.

With that being said, In the time from your last post I found your thread about putting LS1 (now essentially C5) rear brakes on a 12 bolt. Looks like a very simple swap, I have done it on my 4th gen F car (Moser housing and axles) and think I will use them on my chevelle now too. Now I wish I would have not given away the extra set of LS1 backing plates to a friend...:yes:

I am leaning towad the SC&C AFX kit for the front, LS1 F car stuff on the rear (I have some of the stuff already) Looks like a very capable way to go, and with what I have left over from my F car stuff, very reasonably priced!!

This site is great! I have learned more in the last week here than on others in years! Ohhh and Very nice write-up on the LS1 brake conversion!

If you stick with the cage (abutment) from the F body you will be fine - I also did a decent amount of research on the rotors, and the offset of the rotors between the 98-02 F body and C5 are approximately 1/2" different. I assume that some combination of the C5 backing plate and or the abutment makes up for that difference to center the caliper over the rotor.

Thanks for the compliment Matt!

when you do yours post some pictures for others to learn....

This is actually comming together very quickly, I just got off the phone with a F body friend (the guy that got my LS1 backing plates) that JUST changed his mind, he has a 3rd gen F car he is building and called to say he scored a killer deal on C6 calipers and rotors from the dealer (somone backed out ) so I just got a killer deal on his NIB C5 calipers and rotors. :hurray: So I will be talking to Mark again and getting the AFX stuff comming too! Finally a decision and some direction!

Now is time to post in my master cylinder thread so we can figure that out.

Will the stock one work? I have a brand new one on the car now.

My project is morfing into waaaaaay more than planned......

not enough line pressure from an 1 1/8" MC - unless you go with a hydraboost. I have a collection of new and near new 1 1/8" MC's on the bench..... You know if your doing new components at the corners, a new MC, you might as well run new stainless lines and braided flex lines!!! Last winter my new front LCA's turned into a full front end upgrade and replacing every single brake component - that hurt!

FWIW I have already commited to SS braided lines, here again I have waaay to many left overs, I should have 95% of the stuff to do the fronts and If I can find the LS1 rear stuff (easy to do) I have LS1 rear lines from another car I did. I was thinking I didnt wanna destroy my factory Chevelle stuff as its in really Nice shape just dirty. With all the stuff I am changing I probably will replace it all.....the SS part I dunno about tho. Man I am getting a HUGE case of the "might as well's" AKA the "sensuous there's" On the flip side I said I did want to do this right the 1st time.......

Got into this one a little late.. I think the Wilwood setup will out stop the C5 stuff but probably not by a whole lot. I like the fact that you can purchase parts for the C5 stuff anywhere however with the amount most people drive these cars is that really even an issue? You will not go wrong either way and I think you made the right decision by going with the setup off you buddies car as I'm sure you got a great deal.

If I can be of any help to anyone on Wilwood product feel free to give me a ring (number is in signature) I am a factory direct authorized dealer for them and can save you a buck or two!

Happy New year,
