SRT-4 brake swap

[slow99eclipse]

I was wanting to put the 4 piston Brembo capilpers and 12.5'' rotors. Does anyone know if those will work on my 99 GS? I can get them from my buddy for $680 so it's a great deal but not if they won't fit. I know I will have to get a braket made for them but that shouldn't be too difficult. They are going on all 4 corners too, so will that mess up the braking of the vehicle? Please let me know what I should do. Thanks Tim

You'll probably lose emergency brake function unless you do some pretty heavy modification. The stock rear brakes are based on a drum design within the disc. Unless the new calipers and rotors can accommodate this configuration exactly, you're going to have to find a way to connect the e-brake cables to the new calipers. You'll also have to remove the old assemblies and retrofit a new hub that will accept the new rotors (without the old e-brake assembly, obviously) with proper clearance.

Also, bracket fabrication isn't as easy as it seems. You have to take into account several factors, including wheel clearance, offset, etc. Good luck though.

Brembo doesn't make a caliper or big brake kit for the rear.

Why don't you just do a gsx/3000gt sl brake conversion.Dual piston,direct bolt on,and with some SS brake lines,more brakes then your 2g will ever need,unless your building a race car.

Agreed. If I were as concerned about stopping as I am about getting moving in the first place, that would be the route I would take.

Wonder if this does or doesn't work since it appears to fit the 3000GT SL

The 3000GT calipers rest on different brackets from our cars altogether. The brackets from that link were designed to simply upgrade the brakes on a NA 3000GT/Stealth. In theory, thus, they should not fit our cars at all (perhaps the GSX, per the site, but even they don't offer any guarantees on that).

If anyone wants instructions or guidance on how to install 3000GT calipers, Wret did a write up on it, including the template he used to make the brackets.

HHMMNN intersting topic.

Your saying the N/A 3kgt front Dual piston calipers are not a direct fit for the FWD T/E? Accordign to parts stores a loaded caliper is the same for both. I will soon find out since I have a set from a 91 FWD stealth. I eyeballed a 2g AWD caliper (i have one in the attic of the garage) briefly to compare and the appeared to be the same. I was in a hurry and could have missed soemthing i guess.

Now if the FWD calipers and brackets are the same as the GSX setup, i dont see why the brackets listed above wouldnt allow you to mount a set of 3kgt VR-4 calipers. Unless your saying the actual caliper and mounting holes arent the problem and the Caliper location iis the key. I havent looks at a 3kgt to see if the calipers are mounted in the 10 o'clock position.

Perhaps you're right. I've never invested enough time to determine whether or not the NA 3KGT calipers would fit a FWD T/E. If they do, then those brackets might work.

What bothers me, is that it says they've had success with the GSX, but ran into problems with the AWD Talon and GST. From a technical standpoint, problems with the Talon don't make sense.

As for the GST, I always thought GSX caliper conversion kits included new brackets, meaning that perhaps GSX/3000GT N/A/Stealth calipers are interchangeable, but FWD T/E calipers aren't. That could be why they've had problems with the GST. I am not absolutely positive about this, though, so if anyone else knows about eh GSX conversion kits and whether or not they include brackets, please chime in.

 

[Talon ESI-T]

Dont take this the wrong way but, if you dont know for a fact that the non turbo stealth dual piston calipers will or wont fit on the 2gnt FWD as a dual piston upgrade, then why post that they wont?

In fact the 91/92 non turbo stealth/3kgt dual piston calipers and brackets are the same as the 95-99 GSX dual piston setup.

Read first few lines here.

I have looked at mine and they are the same exact thing as the 95-99 AWD dual piston caliper/bracket assy.

Why doesnt the above adapter bracket work? Maybe we are thinking too much. Perhaps its the Rim that causes issues. That bracket doesnt have any offset to it. Meaning the caliper will be positioned out towards the rim. The amount the caliper will be moved will depend on the thickness of the bracket. Remember in 98 the Talon Rim changed. Just a big "maybe" but your higher production kits have an offset bracket so that the centerline of the caliper is still centered on the rotor. Who knows till we try it i guess. The fact that its not offset makes me think we need to put a spacer behind the rotor to make up for the caliper moving outwards towards the rim.

What I originally said (or meant, excuse me for being unclear) is that the 3000GT turbo calipers lay on different brackets altogether.

I didn't understand your link right away... but I'm assuming this is what you meant to post;

About the brackets fitting; I think the rims must be the "issues" they're referring to - I can't think of any other reason why it wouldn't work on a Talon AWD or even a GST.

 

[Talon ESI-T]

Ok i misunderstood you. I thought you were saying the Non turbo setup on the 3kgt was different than the GSX awd setup.

You correct about the Vr4 brakes, they are much different as you said.

It looks like the 4-piston calipers have the same bolt-to-bolt spacing as the TEL calipers. Can anyone confirm or deny this? I also want to bolt the 4-piston Mits 3000GT VR-4 calipers onto 12.5" rotors -- mine are AEM's and I have their brackets.

 

[Talon ESI-T]

In order to use the VR4 calipers you would need to make an adapter bracket. The AEM's wont do you any good.

The center to center spacing is off or the height off the spindle center is off?

I am not really sure, but gst rims at 16 and gsx are 17? talon are 15 swirly?

 

[VelocitàPaola]

The "center to center" spacing is off - meaning the calipers need to spaced further from the hub in order to accomodate the larger rotors.

Good catch napkinthief, larger brakes probably won't work in any rim smaller than about 16". 17" is usually the bare minimum for most aftermarket upgrades like the AEM or Baers.

Isn't the srt-4's bolt pattern 5x100?

 

[Jon Lane]

I think I need to be more clear. By "center-to-center I meant the distance between the caliper's two mounting holes. In other words, is the 3000GT/VR-4 caliper longer (or shorter) between bolt holes than either a 1G T-E-L caliper or a 2G AWD E-L caliper? From the pics in that conversion link, it doesn't look like they're longer than 1G calipers...

If not, I assume the 4-piston Mits caliper just needs to be set from the hub center a comparable distance to clear the outer edge of the rotor, in which case I wonder if the the AEM bracket (which accommodates the 12.5" AEM big rotor) would work.

If the bolt-to-bolt centers between 2G AWD and 3000GT/VR-4 calipers are the same, than the only issues will be properly spacing the caliper from the hub (or from the outer edge of the rotor) and offset/wheel clearance. Assuming there's no grinding on a 2G AWD E-L conversion that wasn't needed for the 1G T-E-L conversion, that is.

Good catch napkinthief, larger brakes probably won't work in any rim smaller than about 16". 17" is usually the bare minimum for most aftermarket upgrades like the AEM or Baers.

In my case I have both OEM and aftermarket 17" wheels and the AEM relocation kit clears the 2G AWD caliper in both.

 

[Jon Lane]

Damn, I'm an idiot: Just looked at the conversion link at http://www.electronicauto.com/products/2gttbrakeconversion/brackets.htm and the 4-pot calipers are clearly longer. Right?

So the question for me is this: Are the 1G and 2G AWD T-E-L calipers the same distance between bolt holes?

Yes, if you get an awd caliper assy from a 1g it will fit your 2g.
