I'm bored and decided after reading through some of these post to upgrade the front brake system on my RX3 from 4 lugs to five lugs and bigger rotors!!! After all it sounds simple and with budget in mind OK let's go for it.According to several post I need 85 big bearing spindles with dust cover and perches,two front 4 piston TII calipers and rotors.I do work on cars as a hobby not professionally and I know things not always goes smooth as you expect, the simple things becomes a pain in the rear sometimes.Anyways I take all my parts and right away I notice a problem with the rotor inner bearing is too big for my spindle,outer bearing is ok and the caliper bracket looks fine. Before posting I read some more and I hope I don't have to buy a 200 re-speed big brake bracket because is that's the case this is not a low budget big brake convertion.I know you guys are probably thinking GET to the point, well what's the solution to make the TII rotor to fit properly into the 85 big bearing spindle.Is there a spacer I need to buy if so who sells it and I hope it's not 199.99 (LOL) I want to thank you in advance for any help. email me angel71171@gmail.com

there is a spacer thing, came with the kit from respeed, it was a pain to put on tho... as for the bracket, you might be able to make it or have a machineshop make it, but you wont be able to mount the calipers without it. in short, you will need the respeed part or equivalent...

why are you trying to be cheap? brakes are very important, and quality is even more important. the quality of respeed's products is top notch, mine even came with free funnies.

i blew my master cylinder when doing the conversion too.. so yes be prepared to spend more money

thunkrd I know a relative who works on a metal fabrication plant so the brackets I can manage.That spacer you're talking about that came with this kit why was a pain to install did you needed a press or take it to a machine shop?Do you know if they sell that spacer separate?? About being cheap, I've been working on this drag racing RX3 for three years and have invested over 40,000 NO BS and I don't have a rich daddy or make easy money I worked for a living until I got laid off three month ago. I don't want the car to be unsafe because of short cuts but the fact is I have spend over $400. on this low budget but efficient big brake upgrade a few more dollars I would have gotten one from the racing store brand spanking new and shiny too.That's what I'm referring when I'm talking about this is not really a low budget brake upgrade.Thanks for your respond,Angel

Go to http://re-speed.com/forums/index.php?showforum=11 and ask Billy. He will help you out, even if you don't buy his products. Great guy who loves to help out.

Also, they are working on a lot of upgrade parts for the older rotaries, things that aren't available anywhere else that I know of. So he may be your new best friend.

Thanks everyone for your info,I've received several emails and it comes down to buying the re-speed bracket and spacer.I'll do a couple of side jobs and buy them in a couple of weeks.I was under the impression you can do the upgrade without the kit.All clear now!!!

Angel,

Billy at re-speed now has one of my Rx3s specifically so that he can develop excellent products for guys like us, I know you are trying to do it on the cheap, contact him and see if maybe you can work out a deal for some sponsorship or something, aside from that I will say that his stuff is well thought out and very safe

it was a pain coz i had to use like 10 tons of force to get them on

angel71171

thunkrd did you took the brackets/spacer to a machine shop to have them press on or do you have a 10 ton press at home or are you being sarcastic and mean you had to use a hammer and fight with them for a little while?? I really want to know since I'm planning to buy these,I don't want any more surprises.thanks

from what ive seen, why don't you just get a new bearing that is the OD of the spindle and the ID of the rotor?

angel71171

Keeble that was the answer I expected,I figure one of so many members doing this low budget upgrades came across this problem and perhaps would tell me hey that happen to me and I got this bearing from this place that took care of the problem and this is the bearing number and where I got it from.I've grew up involved in drag racing and car clubs and that's what happens when you run into a problem someone that already went through hell helps you and tells you their experience so you don't go through the same sh__t.I want to make very clear I'm not putting anyone down or don't appreciate everyone's comments but it seems everyone on this website ran to re-speed and got their problem fix so I'm planning to do the same but it comes down to getting a bearing that is the OD of the spindle and the ID of the rotor that will fix the problem.Florida is not an industrial state,If I was in Cleveland,Ohio from where I grew up I know a few places that customized any bearing you'll like but try explaining that over the phone and I rather paid the money for the brackets and spacer.I like challenges but I'm giving up on this one unless someone tells me where can I get those bearings.Thanks for the input,for a minute I though I was thinking crazy but I guess not.

You will not find a bearing that will do the job. We looked while doing the RnD for our kit. The difference in ID and OD between the two years is huge. Besides the fact that the OD / ID change is only a part of the difference.

What are your goals for the front brake system? Is it for better bolt pattern or actually more stopping power? Are you stuck on a 5 lug solution?

Billy I had the car for 13 years .The car had a 12-A carb stock,then we went to a bridge port with 650 Holley then 13-B etc..... I do this as a hobby and my family specially my son loves it because you know how kids are he goes to school and tell his friends my dad's tiny Mazda is faster than your dad's big Camaro,mustang and so on.As you probably know it's an expensive hobby and you always wants to go faster.If anyone on this thread said otherwise their full of it.I originally was happy doing mid 12's with straight gas from BP.To make the long story short I upgraded many things on my RX3 to make it faster and safer for the last 3 years and I'm almost complete with the project except front brakes ,parachute,turbo exhaust pipe,updates on roll cage to get NHRA certified.I work on it myself,I'm type of handyman and like to mess and custom built things for it.It's fun but until I got laid off from work and I'm anxious to Finish the car but Family is priority I know many racers who rather go hungry to buy a part on summit racing than stop at corner store to buy a gallon of milk,F--K that!!! To answer your question I need more stopping power.I don't want to list everything I have in the car because it will take too long and I'll look like a show off and I'm not like that.I'll post a couple a picture so you can see and everyone that keeps sending me emails stating stop being cheap!!! If I was cheap I never would have been able to built this car it takes alot of money and labor hrs to built this cars and you might know some thing but you can built the whole car alone,no way!! The car should run fasst on the track,let me know what you think.

Certainly a beautiful car!

What bolt pattern is the front currently?
What front strut housings are on it currently?
What is the rear brake system?

-billy

angel71171

Billy Thanks for the compliment, currently the whole front suspension on the car is stock,I replace brake calipers,brake pads,tie rods,rotors,wheel bearings and ball joint with new ones that's it. It has the original 4 bolt pattern,stock front housing.I have a 9" Ford rear end with strange center/pumpkin big bearings inside all the good stuff,I bought a disc brake complete system for the rear end from a Mustang website and I replace the original brake master cylinder with a 1 inch bore tilton cylinder.Front breaks/suspension was one of the last items in my "things to buy list".Trust me that list three years ago was looong!My wife bitch for the longest I told her I stay away from your kitchen you stay away from my garage and I put a lock on the garage ,end of story!!! (LOL)

Ok that helps allot.

The rx7 strut housings will bolt on but they have some inherent problems when bolted to a Rx3. First, the height of them is different. 1979-1980 housings drop the front of an rx3 by around 2.5 to 3 inches. Later model housings will lower it more. Second the king pin inclination is different. This means when bolted on you will have positive camber unless you install camber plates.

So even if you figure out a way to convert the brakes without the use of the Re-Speed kit you will need camber plates and spacers in order to fix the camber and height issues. I have some parts in the works that fix these things but seems you are not looking to add more cost to the brake swap.

You already have 4x110MM front wheels. Your cheapest way is to adapt another rotor onto the stock Rx3 spindle. This allows you to maintain your wheels, strut housings, struts, top mounts and such.

-billy

angel71171

Billy I'll be buying the brackets and spacer from you in the next couple of weeks,I have the camber plates handle and I can also work with the height of the front suspension.You confused me about adopt another rotor using the same rx3 spindle.I'm sorry if this is a dumb ? what exactly do you mean by that? What's the benefit on doing that and how??? My goal is to use the 4 piston TII calipers for better stopping and bigger rotors.Once I get your kit if I run into some issues I'll be asking for your help.Hopefully everything runs smooth.

angel,
with a 1" bore MC, how does it feel without a brake booster.

thanks

angel71171

It stops on a dime,it feels good.This tilton master cylinder are use by nascar and I was told to install it on the car by a well known racer in P.R who is running low 7's.But his not running his stock suspension and break system obviously!!!

As an alternative to our kit as well as to over come the issues I listed.

The idea is to mod the stock hub to mount another rotor that has the correct diameter and thickness for the TII caliper. Would take you a bit of searching for the correct rotor and to make the brackets for the calipers but you seem to like to tinker.

BUY IT! His stuff is the best! Thanks to RE-SPEED i was able to put my favorite rims on my RX3 MS-01's

angel71171

Everyone I have not question the quality or craftsman of re-speed brake kit.Billy sounds like a nice guy and he knows alot of what he sells etc.... My issue was I ran out of my rx3 budget.I'll be buying he's brake kit and possible more in the future so stop making it sound like I don't like what the guy is selling or is not worth the money.I've never said that!!!! Once again I'll be buying the kit so everyone get off my a_s and stop making statement about how cheap and I should buy the kit etc.... I get it,Unless your wealthy don't tell me anyone in here have wanted to buy something but couldn't at that time and had to wait until one or two pay checks to get it!!!!

there is a way to use a booster that is larger than a stock RX-3 (or any old school) with a mazda factory 1" master cylinder. Its currently in the works in my garage. Hope to finalize it within the next few weeks.
