well after a heck of alot of time i have finally been able to prove that there is no way for the 13" baer track system to fit on stock 91-92 Z28 wheels.

according to baer they will fit some..........what ones and how?

the only way i see to make them fit is to alter the caliper by basically removing the cooling fins.

if anyone has some hard facts to prove me wrong.....please do as this saddens me. i was really hoping to fit the 13" just in case i wanted to ever go with a bigger wheel it wouldn't look funny. there goes that idea. it's either a whole new setup or the 12".

ANDYZ28

How did you prove it?

Thanx,ANDYZ28

with the kit on three different z28 wheels. it didn't fit on these sets; would it have fit if i found a 4th set to try?

ANDYZ28

Sorry, I was just asking.

Did you try any 16" firebird wheels? Maybe the 16" cross laced GTA wheels will fit. When I read about the Track kit it said you'd need 17" wheels. I dont understand why Baer would tell you otherwise but then be so general about it. Did the wheel just not fit at all or was it close? Maybe a small spacer or adapter could make it fit? Sorry it didnt work out.

ANDYZ28, i wasn't directing anything towards you; just asking in general.

CrazyHawaiian, you might be able to make them fit with a little larger spacer but then the wheels would really be sticking out funny. the only way to make them fit would be to file down any type of areas like the cooling fins to help clearance issues. even then it would be dang close.

i really wanted the 13" i've always thought about going bigger with rim size; don't know if i can justify it though because i like my rims. looks like i might just go with the 12". just aggrivating to know for 10 dollars more i could have had another inch.

I have seen the 13" Bear track system fit with the 91-92 style Z28 wheels - in fact they are the ONLY ThirdGen wheel that will fit with that kit.

The kit I am referring to has 1-piece 13" rotors (ZR1 rotors) and PBR twin piston calipers. If the kit is an Alcon kit - they won't fit.

The 13" track kit will not fit with older "IROC" wheels or GTA wheels.

Perhaps they have changed the setup.

RMK

Here's what I would like to know. If you go with the 12 inch setup, what is needed to add 13 inch rotors at a later date?

ANDYZ28

My '82 Z28 w/1LE brake system also has the 1991 Z28 wheels. I looked at it today, and (please don't flame me) I don't see why a 13" rotor w/PBR 1LE type calipers would not clear the wheel.

But apparently it won't. But I must say, "that Karl knows what he is talking about".

Thanx,ANDYZ28

I have seen pictures on this site showing the track kit behind the 91-92 rims.... I have no info on what was needed to make them fit, if anything was needed. Like stated above, maybe something has been changed from the previous design?

ANDYZ28

I did a quick search and found this old post;
https://www.thirdgen.org/techbb2/sho...=13+Baer+Track

If I read it correctly? It seems that the Baer Track 13" system does fit behind the '91-'92 Z28 wheels. But it is rather odd that only 2/3 of the rotor surface is used.

Thanx,ANDYZ28

Why not go to Baer's website, download the wheel templet for the system your looking at and then match it up to the wheels. This will tell you if it will fit or not.

yeah i did that too......

if that's the case then it definately won't clear.

does anyone know someone personally who has this here. i hate to go off of the words and purchase the 13" when i can clearly see it doesn't fit. 3 different sets of rims? just seems odd.

i appreciate all the help and suggestions guys!

Go with a set of 17" rims and be done with it.......

Seriously though, if you really want the larger rotors, why not make it happen and go with a nicer, bigger set of wheels at the same time that will provide better looks and handling in their own right? Disregarding money issues of course....

Also, I hesitate to say anything yet, but I see a ton of board traffic lately related to brake kits and feel the need to throw this out there.

One of my friends in the MNF-body Club and myself are in the design process of working on a bolt-on Wilwood front brake kit with 12" Wilwood 48-curved fin rotors and utilizing their SuperLite IIA calipers (4 piston). This guy is a registered Wilwood dealer and already sells a 4th gen front kit with the SuperLite IIAs and the 12" Wilwood rotor and the pricing is very competative with other options for 4th gens (in the $1100 range) and I see no reason that a kit for our cars will be all that much different in pricing. We would like to set it up so the Wilwood 6 pot calipers and 13" rotors can be optioned as well.

This kit will require cutting some of the 'ears' off the spindles but the plan is to utilize an adapter that will mount the caliper to the existing stock bolt holes in the spindle so no drilling and tapping will be required. The other thing this kit will include is a slip-on two-piece rotor with an aluminum rotor hat and an aluminum hub assembly. So no more of the bearing packing mess every time you want to remove the rotors. The AL hub, hat, and caliper will keep weight down as well.

Well I will keep this site updated on progress with this but our plan is to get it mounted up on my GTA within the next couple of months and be ready for sale before spring. We already have a set of hubs to work with and copy so all that is left now is cutting the spindles and designing the hats and caliper mounts. Unfortunately my partner has three kids in different stages of Hockey and is extremely busy this time of year so hard to say exactly when it will all be finished.....

Later,
Matt

Say Matt, you guys should probably fit them on another 3rd gen just to make absolutley sure they will work on all 3rd gens. I know of a black Formula that the owner I'm sure would be willing to help out.

Kandied91Z: Do you actually have the 13" track kit yet - or have you just been using the "templates" to check for clearance??

I am sure that the track kit with 13" rotors fits with 91-92 16" Z28 wheels (MUST be 16")

Perhaps you have the wrong template??

If you do have the kit already then post some pics of where the interfearance is.

Like I said - I have seen this setup work - as in - worked on the car that had these brakes - taken them apart - etc etc...

ANDYZ28

Like I said before, "Karl knows what he is talking about".

Thanx,ANDYZ28

Matt87GTA

Haha.... Hmmm... I don't know if we are looking for another test mule, but I will let Todd know about your offer.... Although I think you are like third or fourth in line behind myself, Eric, Evan, Mike, and possibly Reis.... I just can't wait to get this going and get some pics of it so people can see it in action! It will be an awesome system .

no i don't have my own kit, i did however use one at the shop i plan to purchase mine from. it was extremely tight.

i tried the template from baer, both the printed version and the original and it was also extremely tight. there "might" be enough clearance with the spacing it sits out on; but it's iffy

i think i'm going with the 13" no matter what and then i'll just upgrade to either the 01 ss style or the new z06 in chrome.

just can't decide on which i like better. i don't want to date the car, yet i want it to look classy and still stand out. if they made my rims in 17" i'd buy them in a heartbeat.

thanks for the suggestions everyone.

I downloaded the template a few months ago...printed it (measured the little ruler on the bottom corner to make sure it was printed EXACTLY to scale.....I happend to be at a salvage yard that specializes in fbodies...and grabbed two seperate 91-92 16" rims....when I cut out the template from baer I had left a little bit of extra space just to be certain...and had glued the template onto some cardboard. The template fit both rims...and left quite a bit of extra space (not alot...but enough...dont remember how much exactly). MAYBE Baers setup changed recently...but a few months ago they fit our rims.

Scott_92RS

The Baer 13" Track kit wont clear my 17" wheels.... At least thats what their templates say The wheels are Borbet Type T.

yeah this topic is really an odd one; i'm going to order my set here in a day or so. i'll just have to find out the hard way. what a pita.

RMK

Where are you getting it from? What sort of price are you paying and how much do the options cost?

Regards

Kandied91z - Definitely let me know if they fit with the stock 91-92
wheels. I was thinking about getting the baer claw sport kit with
the 12" rotors, but if the track kit will fit I wouldn't mind spending
the $10 extra.

Kandied91z

iTrader: (7)

as far as i know they won't fit. i sold my wheels and went larger to make sure as i refuse to pay that much money and not have some large looking brakes!!

should they fit? yes, according to some as well as baer....do they? not on mine, i matched them up to 4 different sets of wheels. as far as i'm aware there are only 3 totaly different castings for those wheels from gm so i should have it covered unless there was one i've never heard of or didn't have.


there are those with pictures of them fitting...it could but you may have to modify the fins or realize it's extremely close....

i didn't want to take that chance since i wanted larger rims anyway it was a good excuse.

sorry guys, maybe someone one day will help you out. although i wouldn't know how since like i said i couldn't fit mine without rubbing..........which was more like grinding the rotor.

Nazzz28

Thanks for the notice. I feel the same as you, and if I am going
to spend over $1000 on my front brakes I would prefer the 13"
track kit over the 12" sport when the cost difference is $10. I was
planning on getting 17" wheels in the near future anyways so
I will probably just hold off for a bit. Now I just have to decide
what wheels . I am looking for something that doesn't
need a spacer so I am leaning towards the ROH ZS's (possibly
with the argent center and polished lip) or the Ronal's. I don't
know about the Ronal wheels since they were originally on
the firehawks, but I prefer a simple five spoke design with a
noticeable lip. Kandied91z how are you doing on your wheel
decision and thanks for the info on the baer kits.

Kandied91z

iTrader: (7)

if you need to know anything else let me know!

purchase your brakes first though since different kits cause the wheels to move out more. for instance the single piece rotor pushes the wheels out .4 so if your going with a certain offset you might look to a different one in the front.

i'm not sure on the 2 piece since no one on this site has 2 piece rotors. i'm calling baer monday morning to ask how much they will differ so i know what amount to have my "adapters" cut.

as far as the spacer, adapter thing....i wouldn't worry about it. in fact i went to the autoshow yesterday and noticed that some of the production vehicles that had performance counterparts were using adapters when they upgraded to larger brakes.

a well made adapter is as strong as the hub itself....if you can break aircraft aluminum you were going to break something anyway. however, i still wouldn't try to put drag radials on them as i would just feel safer having only one set of studs used to mount them....especially with any real torque.

like i said, email me if you have any questions...i ordered my kit right after the new year and they said 4-5 weeks tops so i should have it here soon.

Skweezn87

Short memory... I dont have the 13" set.. I have the 12" .. but w/ two piece rotors...

Kandied91z

i thought i had asked that before and didn't recall anyone posting.

13 or 12 really doesn't matter in relation to how much they stick out.

can you please tell me what the distance would be......? do they have the specs written in the instructions? any info you could give would be great as the baer reps are giving me the run around.
