I don't think people get it. A first gen weighs like what? 2300 lbs? 2500 max. You put 4 wheel disc on a car that light and it'll stop quick. I've noticed some fade, but if you're a racer like me, then you'd know that a set of slotted rotors on the front, and ceramic pads all around, and steel braided brake line, and high temp fluid are all you need. With that stuff alone, the car will stand on it's nose. Most brake fade is caused by boiling brake fluid anyway.

My 2 cents to try to save you guys some money and hassle.

It's a KIT people. why spec out every little nut and bolt for it? Why would you need a list? You going to compare it to other kits? Look at the Sevens Only kit, there is even less info on that kit. Why not just have them post up some blue prints of everything, would that make everyone happy?

Look its a kit to put 2nd gen 4 pistion brakes on a first gen. whats in the kit is not all that importain. If it has a doo dab or a dibble flab, it still bolts on the brakes.

Well I am DEFINATELY interested. This is what I wanted. I want to be able to mount OEM TII Rotors and Calipers on my car with NO FABRICATION.

This means I can go to any auto parts and order new
rotors and pads without having to spend more money on Disc "Blanks" - (like custom made Brembo's or *maybe* even the Seven's only kit.)

I don't mind getting the OEM parts myself, but I would like to know what IS included. I don't mind paying for Research - If the product is right.

Hopefully CP will give out a little more info, so I can place my order soon. My Rear End is going to be replaced soon anyway, so I am looking forward to 5 lug wheel options all around.

It's not about specing every bolt, it's about actually seeing at least one part you are going to buy.

I'm unfamiliar with the sevens only kit, but my understanding is that it is actually a "big brake kit" NOT a "brake conversion kit" being labeled as a "big brake kit".

Check your part numbers for oil seals and bearings.
The 84-85 GS, GSL and GSL-SE front spindles are larger.
You cannot use a 81-83 rotor on a 84-85. No worky.

I was going to do this conversion myself due to the fact that I have a TII front and rear rotor and caliper set on the shelf. The price they are asking is reasonable for anybody that cannot manufacture their own stuff and not kill themselves on the first curve they take on the test drive. Drifters will want all the brake power that they can get due to the high speeds and hard braking that is involved.

CP is a very small shop that is trying to create a niche in a market that historicaly is low on cash and is willing to bet their lives on bailing wire and duct tape. These conversions and parts are for the most part cheap compared to the same parts for a FC or a FD.
Stop crying and get a second job to feed the FB!

Long live the sideways life!;)

All 84/85 spindles are the SAME regardless of 12A, 13B, left OR right....

Even after buying the kit you have to match the rims front to back. You now have 15 in the front and 13 or 14 in the back?

which pattern would you guys rather have, the 4 bolt or 5 bolt? I think the 4 bolt would be easier for wheels wouldn't it? Also, how would you convert the rear to the 5 bolt?

Sorry dude you just made me laugh, its a kit huh? You sure do have to come up with alot of parts on your own for this to be a kit. If you send me two brackets I would necessarily consider that a kit. Thats two brakets. I consider the the photo of the wilwood brake set up in the begining of the thread to be a kit. Big brake kits on ebay sell in the range of 600.00 to 700.00 for other cars. So, if I have to come up with every other part conceivable already. WHY CANT I KNOW WHAT MY 350.00 to 375.00 is going to?

Can anyone get a price break down on NEW parts that it would take to get this done? $$$$.$$?

Course most of us are just going to rip out the front struts of a 2nd gen in the junkyard. but used 2nd gen brakes agains NEW 1st gen. 400.00 is more than enough to fix up all four corners on the 1st gen. I threw on another 50.00 for the money you would spend on the front brake assembies at the junk yard if you were luck to get it cheap.

As for 4 or five lug. depends on your car. If you have the GSLSE get the 4 lug. keep your 15 inch tire set in one bolt pattern. If you have the gsl get the 5 lug and the 160.00 cp bolt pattern adapters for the rear and get a set of five lug wheels of the car you got the brakes.:)

BTW this thread is getting old. hope CP sees it sometime in the future.

Even funnier is I bought a "Kit" to convert my factory radio to an aftermarket CD Player, and you know what, it was a bracket and some bolts, and they called it a kit. I had to buy a CD Player and a wiring harness for it to work. :)

All kiddin aside. I'm just trying to say they are selling the parts you can't buy off the shelf. So you can use parts off the shelf. I'm sure they could sell a complete kit with everything you need. but they know we like to bargain shop, or that some of use already have most of the parts laying around on some shelf, or some corner.

I won't be purchasing the kit as I got to much $ in my 4 lug setup to change to the 5 at this point.

ha, this thread is getting totally out of hand. I like the fact that you can use factory parts and still have better brakes. I don't think its too much to ask to have a parts list. And its definatly worthwhile to replace the stock brakes, especially if you have more power than stock. I would think you'd want 5 lug wouldn't you? Seems like that would stronger, and I'm sure theres plenty of wheel choices. I might have to get this kit someday when I have the cash for wheels that will work with it.

would it be possible to use this on the rear brakes aswell?

Do you often spend money without knowing what you're buying? I've got a filing paper organization kit that I could sell you for $20. It's a paper clip sitting on my desk right now.

Here's my message back from Guru racing in Australia regarding there brake kit.


Hi John , the kit will be for the series 4-5-6 callipers , it will be a
total bolt on with no modifications , properly a couple of months to
completion as these centre
bearing cranks are taking up all the machine time at the moment
Seven Stock 50/50 chance hope to be there !!
Cheers Rohan

Subject: series 3 rx-7 brake conversion

Hello,

I was just wondering if the Guru racing brake conversion was complete to use
the Series 4-5 4 piston calipers/rotors on the series 3 rx-7? If so, do you
have any more info on it as well as a price? Are you guys planning to come
down to the USA for sevenstock this year? It will be the last Sevenstock
and it promises to be huge!

cheers
John

What does this do for the offset of the rims? If it is still the same width as stock non-se suspension you will need to find some rims with funky offset to work. And if it changes the width it will make it hard to find front and back rims to work.

Later

We have been directed here by forum members wishing the fire to go out...as per the original thread....please email all questions to info@cpracing.ca or sales@cpracing.ca and someone will answer your questions. As we can not monitor the forums.

For those that are in need of more information, here it is,(we should have put this in the 1st thread, sorry all) the kit mainly consists of 2 spindle adpaters, 2 caliper brackets, 2 custom brackets, hardware and some other very necessary magical, secret componets that we are not posting autocad drawings of online at this time. As much as I wish it was a spacer and a brake line, that is not the case. The kit does work with the factory brake lines by the way.

80-83 spinldes are small than 84-85 spindles for the record, and the 4 or 5 bolt option is there just to be that. Braking after the kit is installed can not be compared to factory braking...at all, braided lines and hawk pads or not.

Re: rim offset- your wheel ends up in the same place it started, no crazy wheels or offsets required. Hope this helped, Cheers

THANK YOU!!

Yes, thank you

Randy

Thank you, now I can see the reason for the price. Sounds like a good upgrade.

Oh you get magical, secret componets. No wonder!

Thanks for the info, thats really all it takes to keep me happy reguarding things like this. Although that magical secret thing has me a little confused. Thats ok though, I be it makes a huge difference, wish I had the money for it.

OK, the ad copy says that we supply "T2 brake rotors and callipers, 5 bolt(T2) or 4 bolt(base model) hub assemblies (including wheel bearings/seals/races), brake pads."
So, how do the T2 rotors work with the 4-bolt hubs (I have a GSL-SE suspension in the '79)?
T2 rotors are bigger than base model rotors, besides having 4-piston calipers, right? So you can't just use base-model rotors with the T2 calipers and CP brackets.
I have an idea given to me by some Chevelle guys over on chevelles.com - they're upgrading their front discs to 13" Corvette discs by machining the braking surface off of the one-piece hub/rotor (like first gens) to create a hub, and then fitting the seperate Corvette 13" rotor onto the hub, and fabricating brackets to mount the matching 4-piston caliper.
I see no reason that this couldn't be done with FC rotors and calipers on a GSL-SE hub that's been machined down. The only sticky bit is the whole T2=5-bolt thing. May be able to use T2 calipers on base rotors... lose some braking force that way, though. Shouldn't cost much to have T2 rotors redrilled, I imagine.

Just a comment about product pricing in general - say the following phrases to any ambulance chasing lawyer and see if his/her eyes light up like an electronic cash register - "auto accident", "sports car", "after market brake conversion kit".

Research and Development is expensive. But Product Liability is what you're paying for, if you expect the company to back their products that is.

I think everyone here understood R&D costs, and appreciates the effort, but really wanted a parts list, which has now been given.

Frankenrex, the hub and the disk are separate on 2nd gens. So it is conceivably possible to use base hubs and 4-pot discs (note TII's aren't the only ones that came with 4-pots on the front, GXL's in the S4 and GTUs in the S5 IIRC also came with them)
