EVO8 Brakes on 2g GSX!!

[suicidal2af]

Nope. There's a third factor that not enough people pay attention to: viz, brake bias. If you take a well-balanced car (in terms of bias) and stick larger front brakes on it, you could well end up with a car that takes much farther to stop (because you are no longer getting much if any help from the rears). There was an article in one of the popular car mags in the last few years about how a fancy front kits hurt braking performance because the car was too front-biased.

An arguable fourth factor is the interface between the driver and the car. If you put on a huge set of brakes (which almost always increases the braking torque for a given amount of line pressure), but make no changes to the master cylinder, you might find that you can no longer find the threshold.

Excuse me, it's been too long since I've talked about older cars. Yeah, bias is a big factor also, although tires are arguably still the most important factor.

I'm used to these fancy electronic brake force distribution systems now which pretty much take bias out of the equation and adjust it on their own, ugh. Electronics are icky.

That being said, my point stands that tossing bigger brakes on are not going to increase your ability to panic-stop from legal speeds.

I know it's a little past the 'bolt-on' stage, but couldn't the brake bias problem be solved by a simple proportioning valve from somewhere like... Pegasus?

Sort of. The first problem is that you need to increase line pressure to the rear, not lower it, so you'd have to delete the stock prop valve. The second problem is that our cars are corner-paired from the master cylinder, which is the safest way, so you'd need two adjustable prop valves, instead of one. Much easier (although maybe a little more expensive) is to do the math to choose a new rear set-up that will put the bias where it needs to be while retaining the stock hydraulics.

As to EBF systems: not really relevant on a DSM site, eh?

My friend put the EVO brakes on his 1g. Just made a braket.

you or your friend wouldn't happen to have any pictures of the bracket?

 

[Artago]

The brake upgrade looks sweet. I wanna do it too now . Tom.

 

[ceedawg]

OK! I have purchased a set, the whole rotor and caliper setup from a 06" Evo.

Right now my car does have Baer brakes with the 13" Eradispeed 2piece rotors in front, and the 2g stck calipers with powerslot rotors in the rear.

Here is the question.

Should I just replace the stck rear caliper and powerslot disc and use the whole Evo rear setup with my Baer brake setup in the front?

or

Should I take off the Baer brake 2 piece 13" Eradispeed rotor and caliper setup I have in the front and just use the whole Evo Brembo caliper and Solid rotor setup on my Talon front and rear?

The calipers on the brembos will be better but the 2-piece rotors will save a ton of weight compared to the Evos heavy-ass rotor unless your gonna replace it with Evo 2-piece rotors at 600 dollars for the front set. I say keep your bears for the weight, it offsets any gains fo a 4-piston opposed caliper.

So you like the Baer's in the front and the brembo's in the back setup. That's what i'm thinking. I guess as long as the braking performance is there with this setup,it will be the way togo and will save me 500.00 bucks from buying the Galant JDM control arms.

So

1.
Baer brake setup FRONT(Eradispeed 2 piece rotor presently on my car)
Brembo setup REAR

vs

2.
Brembo FRONT(solid rotor 4 piston caliper)
Brembo REAR (solid rotor)



#1 possibly being superior?

 

[D_Eclipse9916]

in terms of performance, just keep the Baers and sell the whole setup.

In terms of apperance, two kinds of appearance, trying to stay light, baers up front, brembos in rear.


PURE BLING!! BREMBOS ALL AROUND!!!

Sell the whole front Brembo setup you mean. Also I could'nt care less about BLING. My thing is performance and safety.

I'll probably just get Todd's professional advice. because we are talking about a situation with a floating brake cliper setup in the front and a fixed brake caliper setup in the back as wel with the mix matched setup.

 

[siceclipse]

Sorry to bring this back, but my friend just smashed his Evo and i was wondering if I could just take his Stering Hub's off the car and use them insead of ordering from overseas.

 

[mitsumissile]

You can't use the steering hub off the EVO.

I read that article as well. It was a modded rsx I believe in the back of a SCC. That came right as I was looking to do this. I freaked out when i read how much difference piston diameter could change the rear proportioning. I'd love to stop shorter. Power slots, better pads, ss lines still aren't enough for me. I even have the factory rear vented (and now slotted thanks to RoadRace) rotors. But after reading that article I decided to go more aggresive on the front pads and get the Power slot larger rotors to get the better fade protection without disturbing the front/rear bias and not having to think about things like larger Master cylinders.

I thought I would post up these beauties. Brand spankin' new Brembo OEM 2G GSX rotors versus used Evo 8 OEM rotors. Time for sex.

I didn't get a great measurement, but the diameter of the Evo 8 rotor is roughly around 12.5 inches, compared to the OEM GSX rotors which measure at 10.8 inches. Sweet. The width (only measureing the discs and vented sections) of the GSX rotors measures at roughly 25mm, while the Evo rotors measures at about 32mm. Huge difference.

And you thought this photo was scary.

 

[GRNDSM]

Actually, EVO rotors are 320mm, which is 12.6". That seems to be a popular "big brake" size for newer imports. WRX STI and 350Z also have the same size rotors.

I used EVO rotors on my TR7 project with Viper calipers:

You want 'em? I got 'em. Just can't find them right now.

 

[DSMunknown]

Nevermind. They somehow made it into my Recycle Bin. I'll post them up tomorrow if everyone pleases.

I'm going to bed. Nite.

 

[GRNDSM]

I do not really need these photos yet (though, some day I might do EVO brake conversion to my yet to build AWD Spyder ), but the fact that these photos are missing making this thread rather useless .

 

[theallpowerfulm]

why can this not be done with USDM galant knuckles? Also, instead of getting an OEM set of evo brakes for a little less than a grand, why not spend a bit more and get an aftermarket evo brake setup (usually better than anything offered for dsms)?

I actually made a mistake before. I said the rotors were off an Evo 8, but actually they're off an Evo 9. But they're all the same. Here are the calipers. The calipers are, in fact, off an Evo 8 (they are 4-pot calipers, for those who didn't know). The other calipers in the photos below are used OEM 2-pot GSX front calipers.

In the last two photos you will see the rear calipers off the Evo 8 (which are 2-pot calipers) compared with the same OEM GSX front calipers, just to give you an idea of the size difference.

Here aer some more photos. I realize that the second and third photo in the post above both Evo calipers were slanted at an angle, so I took the liberty of placing something under each of them to get the full effect.

The first two photos are a comparison of the rear Evo 9 rotors to the front Brembo GSX rotors. The rear Evo rotors measure at 11.8 inches. That makes the rear rotors off an Evo 8/9 a full inch larger in diameter than the Brembo GSX front rotors. Amazing.

Thats sweet im hella jealous, good luck though

 

[AndrewD5418]

On 1g, it won't bolt on unless you got braket to fit it.

You would also lose the use of the handbrake .

 

[DSMunknown]

I also forgot to mention that the rear calipers are 2-pot (aka dual piston) calipers. Just in case you didn't notice.

 

[VanIsleDSM]

what year of gallant are those knuckles from? part number possibly?
