Evo 8-10 Brembo Calipers DSM Conversion (for 1g too)

Well I've got the talon version of the gsx mc. Same thing and it's actually still mushy. The upgraded mc is gonna have to go in to fix this issue.

Is it as bad as it was before or you did not feel any improvement.

Do you have SS lines all around?

 

[bsbllfit7]

It's worse after the install and have had the brakes professionally done after I thought I was at fault for the mushy pedal. Yes all the lines are stainless. The pedal is not as firm as it originally was which is why I'm on my quest for the firm pedal.

Ughhhh... Is there anything more unsettling than a mushy brake pedal?

Anyway, please keep us updated on what you find out. I have the setup in boxes ready to install when my chassis gets to that point.

Yes. A mushy brake pedal and screaming Brembo's slowing from 5-0mph barely touching the pedal.

I'm still trying to figure out why my front driverside screams like a banshee after its warmed up from a few stops.

 

[bsbllfit7]

haha that sound is very annoying and it is only at low speed braking

I PM'd EclipseGSX1726.


He is using the stock BB and MC but he upgraded the brake lines. He is also using a Willood proportion valve. I believe he's using 4 piston Rotora calipers and discs in the front,(if that's the correct name) and Evo Brembos in the rear. He says the stock GSX MC and BB feel and work fine. Go figure!

 

[ACM]

It's not the number of pistons in the caliper, but rather the cumulative diameter...

 

[bradikus7]

I am still wanting to know if the FD Rx7 16's will fit over Evo X calipers on a DSM? If not what would be my drag radial/slick options?

 

[cait sith]

No, and why would you need Brembos on a drag car?

Check out Paul Volk's (99gst_racer...I think thats right )set up he has in his gallery.

This we know,just need to know whose setup is working right with a good pedal feel and with what parts.

 

[bradikus7]

Why are you worried about what I need on "MY" car? It is not a drag car, it is a street car that I drag race.

Thanks for the tip agarc023, I will check it out. I know the rims I suggested will clear Evo 8/9 calipers with the 20mm hub centric spacers, but the 10's have slightly taller ears so I am wondering if they will clear. I'm wishing someone with actual experience trying to fit them would chime in instead of people worried about what others want to do with his/her own car.

 

[SOADweskey]

My 17X8 +33 Gram Light 57 Maximums barely clear my EVO 9 brakes. I would be amazed if any 16s fit over them.

 

[ACM]

Another data point - my 16x8.5" Kosei K1s fit over the 3K VR4 brakes on my a/x car but do not fit over Evo 8 front brakes (regardless of whether they're on an Evo 8 or a 2G).

Supposedly, the Koseis have some of the best brake clearance going for a 16" rim. I don't know this as a fact, but they do fit an awful lot of brakes that no other 16" will fit.

This is good information, do they not clear because of the spokes or the barrel design of the rim? If it is a spoke issue that can easily be solved with some 10-20mm hubcentric spacers. Please report back.

No, this was the OD of the caliper hitting the inner rim, long before the wheel was even close to home. I just measured the two calipers - even though the Evo Brembo is huge compared to the 3K VR4 caliper, it is actually slightly slimmer - 5.7" vs 5.8" wide for the VR4. So if the Brembo was on a smaller rotor (VR4-size, for example) it would fit inside the Kosei, but might not need a 1/8" spacer, unlike the VR4 caliper.

My front hubs last 1.5 seasons of autocrossing before the face plate shears off the hub body. I would imagine a 20mm spacer would kill the bearings or the face plate just as quickly, particularly if you use the braking potential of either of these setups.


Hope this helps.

16 inch would clear regardless how wide the rims are. The offset matters the most. +35 and lower on 16 should clear the caliper.

Just installed mine. Looking fresh:

Sort of. The Koseis are only the best for brake clearance when you don't want the wheel to self-destruct. If you don't mind a wheel that has a non-zero chance of falling apart at speed, then Rota Slipstreams have better clearance and have been used with OE Evo 8 brakes.

ps. if you do decide to get Slipstreame, please PM me your full name, social, marital status, and whether you smoke; then give two working days before you drive the car. I thank you and my kids' college funds thank you.

I am only looking for a 16 inch wheel to run at the track just a few times a season, not on a daily basis. I appreciate your info though.

 

[jtmcinder]

If "track" to you is a drag-strip, then that's the only defensible use for a Rota Slipstream and they are quite popular, not only for their clearance, but also for their lack of weight.

Yes, I should be more clear I guess. The drag strip is where I need them. I'd love to run 10's on street tires on 18's but I bet it would be easier with some 16s with slicks.

I will look into them.

I remember reading an article in a mag a while back they took a Honda with slipstreams around the nurburing. They had to come in after two laps. Car was making grinding noises. The wheels had warped and twisted. 2 laps and they were a throwaway item. They are pretty light. I think 9 pounds in a 15x7. Won't see them on my car... Period

The soft pedal you're feeling is because the brake master cylinder size, you'll have to upgrade it to something similar to the Evo's. Some have tried swapping in a Evo BMC with no luck because the fitment, below are a few pictures that Matt Laplante took of his Evo BMC install. What makes it even worse for me, since my car still has the GS-T BMC on it, is that its even SMALLER than the AWD's.
The sizes are as follows:

2g GS-T - 15/16" (0.937")
2g GSX - 1"
Evo - 17/16" (1.062")​

Beau Brown (EclipseGSX1736) found that an easy solution to this is picking up a 300zx TT BMC which is the same 17/16" as the Evo's. Pair it, with the larger 3g GT brake booster and your pedal feel will improve.

'91 300zx TT 1.06" MBC
'03 Eclipse GT 9.75" Brake Booster​

You'll have to bend your own hardlines but your mushy brake pedal will disappear.

Here are the shots of the fitment issues with the Evo BMC.

Joining this party a little late, but after referencing the part numbers, the 3G BB appears to be the same part specified for all 2G and 3G Eclipses.

Perhaps the original 2G BB was superseded? Checking a couple online parts catalogs shows Cardone 532731 listed for 1995-2005 Eclipses.

EDIT: Hmm, also finding that Cardone 53254 is listed for 1G & 2G DSMs. Interesting. Not sure what to make of this, if it is a parts catalog error, or the 3G BB is just backwards compatible and listed as such.

Since when do you even come close to similar brake heat from extended road course work that you would on a drag strip?
