Default bear rotors question

How would one tell the difference between the eradispeeds and the plain baer drilled and slotted?

The Eradispeeds come with a separate anodized aluminum center "top hat" that is screwed onto the rotor itself. There might be other visible differences, but that's the biggest one I know of.

Have a good one,
Mike

Here are pictures of the Baer +1 front and rear rotors. As you can see, they are a two-piece design. If you like what you see, you should purchase them through Shawn at the LAPD...best vendor on the Forum!!!

That rear rotor being half swept looks like butt. Sorry, but any enthusiast has to think the same thing, maybe a different caliper is in order. Some guys have complained about rusting or tarnishing rotors/hats?

Actually, I've never had anything but positive comments about the new rotors. I fully understood when I bought the Eradispeed +1 rear rotor that only half of the rotor would be swept. keep 'em clean and they won't rust! By the way...I am an "enthusiast". This is my 3rd Corvette. 1968 427 tri-power (wish I still had it...damned ex-wife!), 1980 L-82 (yeah it was a dog, but it was still a Vette!)

I just purchased some Eradispeeds and they DO NOT have a separate "top hat". According to the website the Eradispeed + has the anodized aluminum had or a two piece, while the Eradispeeds are just one piece. You can always check http://www.eradispeed.com to be sure.

The "standard" Eradispeed set for the Corvette has a two-piece front and one-piece rear. I just got mine from RG at Exit28. Great price, great service. I believe the set with one-piece fronts and rears are just "Baer Enhanced Rotors", but I may be wrong. Below are pics:

Why not use front calipers on the rear? It would get rid of the 2-tone look to the rear rotors. Maybe use the new 14" Eradispeed rotors w/ZO6 front calipers, front and rear? You'd need 18" wheels all around. :cheers:

Unfortunately, you can't put front calipers on the rear. Although they do fit, they will cause brake bias problems. The front calipers provide about 2/3rds of your braking force and, so far, there's no way to compensate for that.

Default Re: bear rotors question (jw38)

The braking bias can be controlled by the M/C and proportioning valve (about $50-$60), not the calipers. Here is a site that will explain the concept and installation.... http://www.rx7turboturbo.com/robrobi...rake_valve.htm . Just insert the valve into the rear line and dial down the pressure until the desired front rear ratio is achieved. The LPE 650 TT C5 that won the C&D 10,000 HP Shootout had 14" Brembos w/4 piston calipers front and rear. So the 14" Eradispeeds, proportioning valve, and ZO6 front calipers front and rear will work. It will take some effort to get everything installed and tuned...but it would be way cheaper, under $1500, than any other 14" setup. :cheers:

Sorry, I guess my quote was misleading. Baer sells "enhanced" rotors, which are single piece, drilled and slotted. Their Eradispeed rotors are of 2 piece design. The package that Baer sells for C5s typically includes one set of Eradispeed rotors for the fronts, and (I think) a set of enhanced rotors for the rears. That might have something to do with the size of the rotor; the rear may be too small for an aluminum top hat (just guessing here).

The Plus package that Baer sells has a larger rear rotor that is an Eradispeed design (i.e. 2 piece).

Hope this helps,
Mike

HighRPM: My guess is that M/C stands for master cylinder?? When I purchased the Eradispeeds, I contacted Baer directly and discussed the installation of a proportioning valve. I was told that they had tried this set-up but they were never able to get it "dialed in" correctly. It's not just simply a matter of installing a proportioining valve. The computer that controls the anti-lock brake functions must also be adjusted. I really believe that if this is as simple as installing a proportioning valve, it would have been done a long time ago. Just my 2 cents. :cheers: :cheers:

Default Re: bear rotors question (jw38)

Hi jw38....How then does Brembo get their 14" rotor, 4 piston setup to work. Its basically the same as 14" Eradispeeds, w/ZO6 calipers....Alcon has a 13.5" rotor, 4 piston front and rear setup....do these kits use a proportioning valve? I'm getting ready to upgrade my brakes and from what I understand now, the AP setup (14", 6 piston, 13", 4 piston) requires a proportioning valve to work correctly. The AP kit from Mallet uses a valve. As for the anti-lock system, as long as it sees the same relative biasing front to rear it shouldn't need adjustment. Here is a link to one of the options I'm considering: http://www.tradezone.com/vette/apbrakes.html. Thanks for the input..

HighRPM: You raise a great point. It's thre same thing I said to the guys at Baer and they kept on insisting that you can't do this by simply installing a proportioning valve. I took their word for it since they are "brake experts". Maybe someone else who knows brakes (and how they really work) can chime in on this. I'd go with the front calipers on the rear with a proportioning valve in a heartbeat if someone could PROVE to me that it would work!! :cheers:

I think we both talked to the same sales guy at Baer. I couldn't get an acceptable answer other than "we have never tried 14" Eradispeeds on the front". They use 13" rotors on the front so everything fits the stock wheel setup. He said let us know how it works. He wanted to sell me 13.5" Alcon rotors w/4 piston calipers for the front and 14" Eradispeeds for the rear(using ZO6 front rotors). I can't think of a reason why 14" Eradispeeds w/ZO6 front calipers front and rear can't be made to work. I hope someone tries this setup. It should provide great braking for under $1500. As a side note, the stock ZO6 in the C&D shootout stopped 27 feet faster from 150 mph than the the Specter GTR w/15" rotors and 4 piston Alcon calipers. :cheers:
