whats stoping me? (break rotor question)

I am in the body repair process still.

I notice that everyne on the forums is saying that its hard to find rims with the 110 bolt patern. I got 4 wheel disk break cus I got a '82 gsl.

What are some of the things stoping me from finding a rotor size thats the exact size as the stock ones.. but with a differnt bolt patern?

I haev tryed to do some searches on thins.. and come up with rotor as being all most all the time from the engine.. and tons of info on swaping stuff from an 'se or gsl. I have been trying for a while to find this info, any help would be appreciated. Yeah, I need new rotors.. and also to rebuild the stock calipers, and all the cylinders that pertain to breaks and clutches.. but then again it might be cheaper to buy new stuff. Will I need any special tools to rebuild any of those?

Your lug bolts go through the rotor and into the hub, so just swapping the rotor wont work.

ok then.. so your saying that some drilling is needed.


possible options
1. buy a size of rotor thats the same as the ones I ahve now and then have them drilled at 110.. for set screws?

2. buy a set of rotors and have the hub redrilled..?

3. what you thinking would be good?

Just buy some stock replacement rotors, do an eBay search, no drilling required.

because of the lack of wheels that are made in the stock bolt patern. Funny you should mention ebay I was just looking there to see of I could find the size of the break rotors.

You have to replace the spindles/hubs and rear axles as well as the rotors to change the bolt pattern, becaus ethe wheels don't mount to the rotors. The rotors are sandwiched between the wheel and the hub, and the lug bolts/studs go through them. The easiest way to change your bolt pattern is probably to swap the spindles and axles from a GSL/SE into your car. It's not too hard to do but sometimes finding a doner car can be a little tough.

In my region seeing a 'se is hard enough... let alone a donor car. I don't want to pay outrages shipping prices when someone has one for sale or compete with someone else thats looking to do the same thing on ebay.

I just want more options for wheel sizeing. I guess having them redrilled is also a posibility.. but how much would something like that take? I think I am going to ask the tirerack if they would do something like that. I saw some wheels on there I would love to buy. I sure wouldn;t want some adaptors made, I am afraid them might break. I wonder how much do those cost.

There was a place making new brake parts for our cars. Theraceshop??? or something like that. they were making new rotors that would fit our spindles. they could then easly change the bolt pattern for you.

from what i've heard, redrilling the wheels costs about 50 bucks each, and to get adaptors, you're looking at at least 240 bucks total. so if you're scared of adaptors, i'd look into redrill ing wheels

Not to be too much of a smartarse, but try the search spelling it "brake" rotors.

First gen front brake rotors are built into the hubs. The only bolt on solution is to use "SE" parts. You will need to swap the entire set of struts as well as the entire rear end due to your car being an 1982 model with small bearings front and rear.

You can use adaptors.

You can convert to second generation brakes by purchasing a kit. You would still need 84-85 strut housings to do this.

You can go the racing store's route.

You can save your money and purchase some wheels that fit the 110 pattern if you look hard enough for them.

I spelled it like that only this one time; however, whensearchingthe forums I searched with "brake rotor", " brake swap" , "brake options" and a few other ways. I think that the search system should be revamped to include better search terms for instance in ebay you can search more precise for rx7 1st gen parts if you use the advance search options. When I search for parts I need.. say a short shift for my car I do.. rx7 shifter -(stock, bushings) more of the time nothing comes up cus I don't think they make short shifters for 1st gens.

thanks for the links guys

when I read the discriptions it says "Very easy to install, you simply remove your factory hub, rotor and caliper and replace them with our Billet Hubs, Billet Calipers and brackets." taken from: http://www.theracingstore.com/brakes_4piston_bkit.html

so then useing my rear end.. all I will need is axels.. that sound about right?

well I gave them a call and I was told they only make fronts. no rears..wow, maybe I understud that wrong.

Maybe cus I got a '82, he said he doesn;t make them. I am not sure for the 'se in 85 though.

Anyone know if I get the 9" rear with brakes from the yard, what size wheels I would have to end up buying..? I am looking to get into something in the 17" world somthing nice and wide so it can hug the tar when I rip off in 1st

There is a certain Canadian firm that sells a collar for the spindle and caliper bracket so that you can upgrade to Gen 2 brakes along with the 5 bolt pattern.

Problem is the reputation of this firm is such that I don't dare give out the name for fear of flaming and bannishment.

I think that to place an order you should call to see if it's in stock then forward your money to someone who lives near so that they can pick it up and ship it to you...

It's pretty much standard for big brake kits to just upgrade the front brakes.

sevensonly kit and also the respeed kits are front only. Did you ask what calipers they use? is it just wilwood or a good brand like stoptech or brembo?

nope, I didn't ask what they were. The thought of getting a set steped out of my mind when they said they didn't have the rears. I guess I should have asked for more info on them and posted it for everyone else to read. You can send them an email to find more info from the link that was posted.

So my options are to swap for 'se set up.. or what?
