Big Rotor Upgrade, pre-facelift..likely to work ?

[EdmundVR4]

Got these part #'s from my part supplier. (knuckles, aka hub carriers, spindles ?)
EC5A-0300627 (Facelift model)
#32300L, PART #MR369425, KNUCKLE LH,
#32300R, PART #MR369426, KNUCKLE RH,

EC5A-0000234 (pre-facelift)
#32300L, PART #MR223628, KNUCKLE LH,
#32300R, PART #MR223629, KNUCKLE RH,

^^^ The pre-facelift knuckles have the same part number as the 95'99 USDM Eclipse. If this is so, PowerSlot has "the affordable big brake system"

http://www.powerslot.com/pages/power_slot_plus.html
Introducing the Power Slot Plus Big Brake System. The Power Slot Plus system uses a larger diameter, premium quality Power Slot brake rotor combined with your original factory brake calipers. Our patented caliper relocation brackets space the factory caliper further away from the hub to accommodate our oversized brake rotor. This increases brake torque force without affecting pedal effort or travel. The larger rotor is also a more effective heat sink, absorbing the heat generated under heavy braking. This greatly reduces brake fade and provides consistently shorter stopping distances, especially from higher speeds.

NOTE: All Power Slot Plus brake kits require the use of larger diameter wheels. Check the dimensions of your wheels carefully before purchasing.

KEY FEATURES:
· Premium quality, larger diameter Power Slot rotor
with Vac-U-Slot technology
· Relocates the factory brake caliper for increased
braking effectiveness
· No special brake pad sizes required. Just use an original equipment-
sized high performance pad (sold separately)
· Patented design U.S. Patent # 6,305,509

What do you guys think ?

i heard/read..
..
the us galants all have facelift/brembo spacing on there hub carrier mounts,
so the adapter to move the caliper wouldnt work on our prefacelifts?

should be fine on the facelift model thou?

where did you get the us part numbers form because i thought there 8g galant had a different suspension to ours,
but the 7g galant/eclipse is the same....

im using 7g eclipse camber kit in my legnum.

[EdmundVR4]

^^^My post said that the USDM ECLIPSE knuckles are the same as pre-facelift VR4's. (same part #'s) So, it should work & yes the Eclipse & VR4's (7G&8G) suspension are virtually identical.
I got the US part #'s from CAPS (US version)

Spirit posted a link to National Brakes Catalog:

http://www.clubvr4.com/forum/showthread.php?t=15730

From the catalog the Eclipse you mention seems to have discs that are 276mm diameter yet the Facelift VR-4 has 294mm diameter at the front (no mention of Pre-Facelift VR-4s). I thought the discs from Pre and Post Facelifts had the same diameter but different hub carriers. So that would mean the Powerslot kit for the Eclipse wouldn't fit surely?

^^^ If the Knuckles (hub carriers) have the same part # (Eclipse & pre-facelift VR4), won't the disc bolt up (276 or 294mm) ? I don't think the difference in disc size matters.
And yes, I think the PowerSlot kit will fit.

[Nick Mann]

Anyone know of an eclipse owner that would remove a wheel and measure the bolt spacing? It's the only way to tell apart from someone buying an eclipse hub carrier and comparing it.

[phosty]

I thought that the Powerslot caliper adaptor would have be specific to the disc size that was originally fitted?

So if the discs are not the same size on the Eclipse & VR4 Pre-Facelift but they share the same Knuckle/Hub-carrier then the calipers on the Eclipse and VR4 must make up the difference.

So that would mean Powerslot make an adaptor to move the Eclipse caliper to the required position for the new bigger discs. Which means they probably won't work if the VR4 calipers are different (since the VR4 caliper has to place the pads 18mm further out to fit the normally bigger VR4 discs).

Can you check CAPS to see if the caliper part# is the same between the Eclipse and VR4 Pre-facelift? Or does one or the other use an extra adaptor piece? I can't see it working otherwise.

Unless of course the Pre-facelift disc is smaller than the Facelift (and the same as the eclipse)? Anyone know that? The National brakes catalog had no info on the Pre-Facelift disc size.

[EdmundVR4]

Good points phosty.
I only have US CAPS & the 95-99 Eclipse (D33A) part # for Caliper Kit...PNC 51023L / Part # MB950176.
Can anyone check the EC5A VR4 Pre-facelift part # ?

I own a 1995 Eagle Talon (Same thing as an eclipse here in the US). The bolt spacing for the brake caliper bracket IS 130 mm. I am not sure about yours, but i think it is 160mm? Can anybody confirm this? I am actually trying to switch to an 8g galant knuckle right now so I can use evo brakes in front. The problem is all the US galants have mcphearson struts where as the 95-99 eclipse/talons use multilink.

More info here: http://www.dsmtuners.com/forums/articles-suspension-brakes/260580-diy-install-evo-brakes-brembo-g2.html

[Nick Mann]

Facelift 8g Galants do have a bolt spacing of 160mm, as per the Evo's.

I guess 130mm is the pre-facelift 8g spacing. I can't tell you for sure at the moment!

[redleader36]

Hmm . . interesting . . Would anybody like to trade a set of used knuckles with the 160mm bolt pattern for my used set of knuckles with the 130mm bolt pattern?

Attatched picture shows Galant knuckle on left, eclipse knuckle on right (borrowed from wbed)

[Davezj]

yes 130mm is about right 128/130mm is all in the measurement.

I doubt you will get any luck... swapping for brembo compatible hub carriers is a very commonly wanted upgrade and as such any facelift hub carriers usually get snapped up very very quickly. :(

[phosty]

I measured up my caliper bolt spacing a while back and measured a rough 130mm spacing (I was unable to unbolt it to measure precisely). Its a 1996 Pre-facelift Legnum VR4.

I later enquired about big brake upgrades from KAD and they told me the spacing on their drawings was 128mm for the pre-facelift so I wasn't far off.

[redleader36]

Do you guys have any suggestions on where to get an 8g galant knuckle from? i would need it shipped to the USA, obviously.

[redleader36]

(you guys probably know this already) also, in the us, the galants have mcphearson struts, so the knuckles look like this:

[Nick Mann]

You can buy them from mitsubishi dealers in the UK. That would not be a cheap option though!

In the UK they are in demand anyway, because many owners of pre-facelift cars want to have an easy Evo Brembo upgrade. So second hand from the UK would be difficult too.

I'm not sure if they could help, but www.rhdjapan.com are good for sourcing parts for the 8g VR4. They may be able to help?

Second hand, your best bet would probably be New Zealand - a place called Kempy's. I think they have a web address, but you would need to search for it - I don't know it offhand.

If you need the part numbers, let us know. We could certainly get you that much info!

[redleader36]

I might need the part numbers. I've heard they are MR369425 for the left knuckle and MR369426 for the right one. Can anyone confirm this. I don't have a euro copy of caps so I can't look this up.

if both model's hub carriers were the same, then that would also mean we can use the eclipse's big brake kit.. which can be bought "off the shelves"

[phosty]

A 12.5" rotor should give roughly a (12.5 x 25.4)/(294) = 1.08 i.e. 8% increase in stopping torque. How much improvment do just upgraded pads / rotors (of same size) give? I realise there are other things that affect stopping power too but I'm just trying to think this through a little.

I agree as we share the same knuckles we probably could use a normal full Eclipse big brake kit - one that provides a new rotor (330mm or 356mm i.e. http://www.ksport.co.uk/order.asp?id=239&loc=2 ) and caliper (6pot ? 8 pot ?) and caliper mounting bracket. Big money too!

However the Powerslot system uses the OEM caliper and moves it out a bit to fit a bigger custom rotor. So I suspect only if the knuckle AND the caliper are the same part numbers (or more importantly the same size) would their Eclipse kit work for the prefacelift VR4s.

We have confirmed the knuckles share the same part no. How about the calipers:

EC5W-0012063 (Pre-Facelift):
MR370775 (PNC 51023L) Left Caliper Kit, FR Brake
MR370776 (PNC 51023R) Right Caliper Kit, FR Brake

Can you confirm the 95'99 USDM Eclipse AWD caliper part numbers? I tried looking up Eclipse data in my copy of CAPS - it lists a 'D27A 2000/4WD' Model code. However the caliper and knuckle part numbers are:

MB699705 (PNC 51023L) Left Caliper Kit, FR Brake
MB699706 (PNC 51023R) Right Caliper Kit, FR Brake
MB518225 (PNC 32300L) Knuckle, LH
MB518226 (PNC 32300R) Knuckle, RH

So this probably isn't the USDM Eclipse we're talking about.

Don't get me wrong - I might be tempted - strong £ and all that.

They don't seem to have any UK/European distributors listed on their website.

[naughtika]

as far as i know 2g eclipse (95-99) came in different variants..

GS - Front wheel drive and non turbo
GSX - All-Wheel-Drive and non turbo
GST - Front Wheel Drive and turbo

can someone cross-ref between the different variants..

[redleader36]

a 95-99 eclipse is a d33, not a d27. let me see what i can find for caliper part no.

[naughtika]

any updates one these?

[phosty]

I sent the Powerslot guys in the US an email before Xmas and they replied in January to say they were looking into this for the VR4's. BUt I haven't heard from them since.

I'll checkup with them.

[gee118]

Any update of what you did here in the end?
Looks like I need new discs on my pre-facelift and i now want the cheapest and best and easiest upgrade.... if those three are compatible in any way

[phosty]

I never got a reply to my emails.
