Well, yes.... if you wanted to pay that much... which none of us do. That is why we're all looking at this thread

How does Baer do it then?
Or the people who use the 13" cobra setup?
Do they just work cause the PBR caliper is lower profile?

The PBR's are a two-piston floating design, similar to original equipment. Since the pistions are on the inboard side of the rotor, they do not have the same clearnce issues. The fixed, four-piston calipers have a pair of pistons on each side.

I dont know if this is common knowledge or not, but the first production runs of the 2g eclipse gsx and talon tsi awd had larger rear rotors that where vented, and the calipers sat a bit taller to compensate. these are a direct swap to the later ones with the solid and smaller rear disc as well.

just seing the pics of the rear TT wret posted looks basically just the same. no bending or adding of spacers needed.... but i havent yet measuered the piston sizes yet to see if they are the same or not.

Never the less, I'll match or beat a price if someone wants to buy calipers, pads, hoses...

Todd, I may have missed something reading thru this thread, but whose product are you meeting or beating? Is that someone specific or anyone who is selling calipers,pads,hoses?

It's ok... just wish I knew the hub was wrong before I ordered on. doh!

Does anyone have specs on the AEM rotors? I know the GSX version is 12.5" in dia, but I can't find any info on the offset and the thickness.

Click to expand...

They're 24mm thick and the hats stand 30mm off the hat-side face. I have artwork for the Wilwood FSL caliper with these and can develop it for others if you have precise caliper dimensions.

What do you guys think of those upgrade "kits" that basically re-use the oem calipers with spacers to supposedly give them more torque? Looks like other than that they only use large rotors and other hardware.

I was talking to Garry Marsh once when he was working on a guy's car who had huge brembos on his 2G. Cost in the area of $4000 for his front/rear setup. Garry said this was gross overkill and a waste of money as the stock brakes are good enough. If this is true, perhaps aftermarket calipers are not necessary if one simply upgrades to a large rotor and comparable pads with ss lines?

Can someone confirm the radius of the stock caliper mounting point's centers? IOW, the radius of the big blue circle? It's been awhile and I want to confirm some of my earlier drawings.

autozone has pic of all rotors with measurements but I can't scale them or fix them to be able to read them. any one know how? http://www.autozone.com/R,APP119038...partType,00854/shopping/partProductDetail.htm

I get some weird error. Where can I find it on their site?

goto autozone.com pick any car and look at the rotors. they have pictures with all the dimensions but they are 200x200.try this one http://www.autozone.com/images/products/aim/aim31002003.jpg

I found some better pics at this site with good dimensions http://catalog.brakewarehouse.com/i...ID=25G145ZGM25G146IR1&clientid=brakewarehouse
eclass rotors look kinda promising nm only 11.3 inch
http://catalog.brakewarehouse.com/i...ID=25G145ZGM25G163HTN&clientid=brakewarehouse
I need to reread this thread to get a better understanding of the hat offset I need to make this bolt on

Has anybody looked at 350z, g35 rotors and calipers? they share the same bolt pattern with us.

I think those calipers are the same as the EVO's...

You are right on track.

Brakes dissipate heat-energy primarily through convection (search my old post on brakes). Rotor surface area (diameter) is required to improve convection h=qAv for those MECH-Engineers. Next comes premium lining material (not organic - fade resistant - good mu). Cooling can be helped by ducts, rotor fin design, holes, slots, wide gap rotor (32mm wide), and open style wheels. Keep in mind that power input to rotors by braking is ten times your ability to pull heat out of the rotors through cooling.

Fixed piston calipers can provide minor advantages for things like taper pad wear. The main thing is they look cool.

I put Nissan 300ZX calipers & Wilwood 320x32mm 2pc rotors on my car $150 ebay calipers 2x$60 aluminum hats, 2x$70 rotors... roughly $400-500 for the whole deal. I fabbed the adaptor brackets.

FYI: Wheel offset plays a huge roll in caliper clearance. Stay away from spacing with washers... does it work... yes... but you can also eliminate the saftey wire on your 2-pc rotor hat-bolts and that works... right?

wret said:

2g 3000GT VR-4 rotors are a direct fit but they place the calipers so far out that you need spacers to fit your wheels over them. The Audi rotors mitigate this clearance issue but they are not a direct fit--you need to reduce the hub size to make them fit.

The dimensions of the brackets in the first couple pages of this thread are as clear as I can make them.

I am gonna give it the old college try. I have the wheels from the buyin mitch done a while back. 17x9 with big offset. The 275's appear to clear fine with the car sitting still, and the space you have for these 3000gt calipers is crazy. Mine should be here to do some test fitting next week. I am gonna put them on with the 13" cobra rotors to start with and see how it fits. I will let everyone know how it fits when I am done.

Let me know how that works out, it'd be nice to ditch the wheel spacers.

Take pictures of the 17x9 and what offset on the road while your at it too!

Looking great!

Congrats for a job well done. im looking forward to the write-up.

I know that, I'm bringing this thread back from the dead, but I have a question.

Coil-overs, 17x9 wheels with 27mm offset, and some 13.1" rotors of Cobra rotors(which year specifically???), with 1G 3000Gt VR4 calipers

Would this combo work on 1G AWD? Also is there any secific write-up on how to upgrade brake booster master cylinder? Thanks.

Does anyone know the thickness of the spindle's caliper mounting ears on the front of a 2G? This is the meat surrounding the two holes where the 12mm bolts pass on their way to the OEM calipers.

They are 7/16ths thick, and 1" overall DIA. Do you need it more exact than that?

I had some adapters made for Camaro/ Corvette calipers
On my black cherry I have Evo rotors with 2g 3kgt vr4 calipers.
Also, you can use the 3kgt spindle and Evo struts and that setup does not require an adapter.

How do these compare to the 3kGT calipers?

Is your black cherry a 1G or 2G DSM? What kind of caliper clearance do you have with your wheels and what wheels are on it? Size, offset, spoke thickness?

Those are bolt-on? I'm not familiar with the 3kGT suspension, so again: are we talking bolt-ons for 1G or 2G DSM?

delta448 said:

I'm pretty sure they're about the same size. I know they fit under 15" rims. The Corvette ones range from 38-43mm dual/ 3 piston.

mine is a 1g. I have +35 17x9 wheels.

Doesn't matter, just use the Evo suspension with the 3kgt spindle.

I have been waitin for somebody to bring this back from the dead. I have the cobra rotors at home and I have the 3kgt calipers. I fabbed the rotor and caliper on the car and I definitely need spacers. I run 18x8 TSW with a 40mm offset, so I cant run spacers, they would stick out to much. I am now looking at the audi a6 rotors. When I went to autozones site they are showing them as being a 6 lug. Is this right?

what year evo suspension? do the ball joints and tie rods and axles line up good? did you have to use spacers on your wheels
