3/s 4 piston calipers, who's using them?

[Constant_Project21]

So I'm just looking for info or maybe some feedback from people who have done the 3/s front brake conversion. I know that they require a custom bracket for them to work and bolt up.

Guess what i'm looking for, is has anyone used these? Anyone have the brackets (would like to take a look at them, maybe see if a local shop could fab them up)? Anyone heard of any problems people run into while using them?

Just looking for some input, seems like a pretty nice big brake upgrade, that could be done realitively cheap.
Thanks ahead of time!

Oh and I realize there's kits out there, but I do not wanna spend $115 for 2 brackets.

I can't comment on the 3S ones, but I did do a write-up on here for using the Mustang Cobra brakes (nearly identical to the Baer upgrade kit). Might be another option for you to chew on.

[Constant_Project21]

Yea I was following your write up on that, did you ever have primo look at those brackets to see if they can fab them up?

I know that NT 3000gt SL brakes (dual piston) are bolt on for dsm's, but I would just do 2g gsx brakes up front if I wanted to be simple..but I'm obviously trying be difficult.

Also read up on tuners a bit, and saw that the stock offset on dsm rims, don't clear the vr4 TT calipers, but evo 8/9 rims do. Just posting what I know lol.

Also, try to refrain from jumping on the "more pistons = better" bandwagon. Just because one has more pistons, does not make it better.

I do remember hearing about rim clearance issues with the mitsu 4-piston setup. It's those 2 outer pistons that make em so damn wide, you might have to run spacers with certain rims.

Yes the cobra/baer setup is 2-piston, but keep in mind not all 2-piston setups are equal. The cobra/baer setup adds a much larger rotor, which is a good thing because now you have a larger "lever" (think about how a breaker bar works). Stock 2-piston calipers on a stock rotor is a decent setup, but a larger rotor will allow for better braking torque, so make sure to keep that in mind.

As for the brackets, I completely forgot about working with Primo about that. I'll have to give them a ring because I realised I put the calipers on wrong. I put the bleeder nipples facing down, and they are supposed to face up (because air rises and you want to bleed out the air, so they should be at the top). So when I do that swap, maybe I'll pay them a visit, they're minutes from my work

[Constant_Project21]

I wasn't necessarily thinking more pistons the better, that's kinda why I was looking for input to see if it was at all worth it.

The cobra kit is on the brain as well, and I posted something up in primo's section as a little reminder to them. Keep me posted on any developments on that!

[Halon]

Will do man!

Guess I can be open to other big brake conversions. I'm just looking for a cheap effective upgrade. So anyone else do a different upgrade? 2g twin pistons, been there done that, so just looking for other options.

Sorry about half answering and then falling asleep yesterday. The 3000GT brakes on my VR-4 are from a standard 3000GT. Elite Autosport actually fabricated the brackets for the conversion, so you may want to give them a ring.

^^like I've been texting you, almost positive you have the twin turbo calipers. 3kgt vr4 calipers are 4 piston, and have those neat calipers that say mitsubishi on them, correct me if I'm wrong?

[Chim55117]

I called my brother. Yes, they are 3000GT VR-4 4 pistons. It says Mitsubishi on each caliper.

[Constant_Project21]

Sweet, I might have to stop by and take a look at how those are set up...

Anytime. Give me a text sometime and I'll let you know if I'm free to show you the VR-4. It's in storage in Arden Hills.

[Constant_Project21]

That's kinda shitty, all I really need to see are the brackets, but that would require disassembly...Hmm

[s1ngletracker]

me. on my 3/s

But really, someone should take a set to primo and have them do some low-cost reproductions for the rest of us!

[Constant_Project21]

That was kinda the plan. That's what halon is trying to accomplish with his cobra brackets. I just need the brackets!!! I found some calipers pretty cheap, soooo just need cheap brackets

[s1ngletracker]

dude, you dont even have a running car. Why you spending money on brakes? :P

[Constant_Project21]

It's planning Paul, I haven't bought anything, I'm just researching for when I get to fixing. Figure since it's not moving, I might as well go through everything this time, and make sure the maintenence is all done. I know I need front brakes, so why not make um better while I'm at it.

Have quite a few plans for it before I toss a motor in it, cause if I can't drive it, then I won't be tempted to cut corners like I have on my other dsm's...haha.

[Halon]

I fired up the heater in the garage. I'll be taking them off today. I wrote them a message in their vendor forum, but no one ever said anything back???

[Constant_Project21]

I did as well, those primo guys are sometimes too cool respond (jk'ing guys). Sometimes it takes a couple reminders.
