Roush Rear Disk Brakes - 95 S351R

[95-S351R-029]

Was looking at the rear disk brakes on the ole' beasty and it seems they are the stock Mustang Rotors & Calipers.

I looked on Saleen's site, but it seems they only provide a 13" Front Disk Brake upgrade system. I'd like all four to be the same, maybe that's not possible.

If I can't put a Saleen set on the rear, what would be the recommended upgrade?

Thanks.

....I'm sure a company or two make a 13" rear brake kit however it might be overkill as those rears don't do much of the brakeing compared to the fronts. There are two different routes that I have been thinking about on the speedster myself.....

1). doing the 12" Cobra rear brakes would be the simplest route and most likely the best performance
2). Bear makes a 13" rotor for the rear that uses the existing caliper and pad that makes the brakes look symmetrical to the fronts and is really inexpensive...

I'm sure there are other systems out there that I'm missing that someone else will bring up and make me regard, once again, jumping in to reply first

I thought about a Cobra setup, but the symmetry you spoke of is a conceren, all bit it not a major one, as that is blown as it stands today. More importantly though is their functional operation. Once I get the beasty rolling, I want to make sure it stops !! Granted, the front breaks take care => 70% of the work in stopping, hence the seemingly never ending supply of "Break Dust" congregating on my front wheels

Re: Bear Rotors: That's seems like a reasonable compromise, Bear Rotors + After-Market HD calipers.

I guess it all comes down to "How Much Does One Want To Spend"

Be advised that the Baer 13" rear rotors are solid - not vented. May not matter on the first stop, but I could see that being a problem with repeated hi-speed use. The 12" Cobra rears are vented...

...I'll have to call you out on this one Bob, as I'm sure the owner of the car who has the 13" Baer Kit on his Saleen will back me up. Not more then 48 hours ago at the Knott's Show did I see the brake setup and you have a few options on the rotors: solid or vented: cross drilled or slotted. Todd (gonen20) has the slotted (can't recall if they are solid or vented) 13" rear upgrade on his 2000 S281SC vert and it looks, IMHO, very good. Again, not sure on the performance of this particular setup but it does look very impressive( matches those front sexy Alcons he's got).......

No problem - I should have probably clarified the above post anyway... I was speaking of the Eradispeed Plus 13" rear upgrade, as it's closest in cost to the Ford Cobra 12" upgrade (which can be bought as cheap as $175). I think the Cobra setup is tough to beat for the money.

Baer offers a couple different rear kits.

The 13" rear "Eradispeed Plus Rear Upgrade Kit" that you see advertised on Ebay for about $300 does use solid rotors. Yes, you can get them drilled, but they are not vented. I've heard that those are noisy as well, since super-heated air gets trapped in the drilled holes as the pad passes over the hole. When the pad is past, the air escapes, giving a "popping" noise...

The next step up from that kit is Baer's "Sport Rear Disc". Nearly identical to the 12" Cobra setup, and $1000-$1200...

Finally, Baer also offers a "Track 13" Rear Kit", if you're willing to part with $1400 - it DOES have vented 13" rotors...

Here's a link to the Eradispeed Plus kit that shows the rotors pretty well: http://www.speedconcepts.net/product_info.php?products_id=694

You'll note that they are slotted/drilled, but not vented. If I'm missing something here, or there's another Baer kit out there, please edjumicate me!

I have the Baer Kit in the front (GT kit) with Eradi Speed rear Rotors. I'd do it again cause Baer is affordable. I haven't had any problems. All my rotors are drilled and slotted. 13" front and rear.

Sorry, but the rear rotor in that picture is a drilled and slotted solid rotor, not a VENTED rotor.

There seems to be a misconception of what a vented rotor is.
this is a vented disc rotor:

This is a cross-drilled, slotted, solid (non-vented) rotor like the Eradispeed kit uses:

The solid (non-vented) rotors are only 3/8" - 1/2" thick, whereas a true vented rotor will be 3/4" - 1-1/4" thick (depending on application).

I have the Baer kit on my car, both rotors are cross drilled, slotted, and vented rotors. come to think of it though, I don't believe that I have the eradispeed rotors. Mine were different.. I don't know which ones I have but I don't believe that they are eradispeed. Just went to there website, www.baer.com, click on complete systems and there track and track plus systems shows a picture of the rear rotors and calipers that they come with, it clearly shows the rotors being cross drilled, slotted, and vented rotors. there yea go...

Here is a picture, but not a very good one because I'm in guam, it's cropped from some pictures that I took when I went home a few months ago.

If you are looking for opinions...... well

If your Alcon's ( front brakes ) are working properly your car will almost do an endo no shi*. I know that big rear rotors look awesome but when you actually compare stopping distances between cars with aftermarket rear set ups the cars really don't stop much in a shorter distance with larger brakes out back. This of course for a street car that's hardly balanced like an S351. Don't worry, I'm not picking. I'm a former owner.
If you are doing open track weekend work with the car just give your car a couple of runs with the Saleen/Alcon stock set up. I know, I know the rears look wimpy through those beautiful Speedlines but if the look really bothers you just throw some drilled rotors in the back for the look and save the rear brake setup dough for your next engine rebuild.

+1 for the Cobra upgrade, it is what I have on my car. All you need are new pads, the rotors, caliper brackets, and anti-moan brackets. You can get nice Brembo rotors and paint the caliper and brackets to match the front.

Now you have tons of pad and rotor options, and OEM parts availability. A 12" vented and slotted rotor will be plenty stopping power and it outperforms anything under $1,000 easily. The baer 13" upgrade mentioned above just uses a non-vented rotor in the rear, which I feel is more for looks than performance.

The install on the cobra rear is pretty easy, hardest part is pulling the axles.

Thanks for all the feedback !!! It looks as though there are many more options than I first thought.

I took the beasty into the Wheel shop today to get a face lift on all four wheel's. Took it down to Wheel Techniques in Santa Clara, CA.

Web-Site ==> Wheel Techniques

Going up to Half Moon Bay Sunday, leading of course, a parade of SS 396 Chevelle's Should be a good show !!

See you there !!

I have the bear 13' rear kit eidraspeed and to clear things up a bit, there NOT VENTED, but they are sloted and drilled, to become a vented "kit" you must change the caliper ie: the 12' cobra kit or the all out bear kit that comes with new calipers and costs around $1000.

 

[deezbluballz]

I had a little typo I meant drilled and slotted, not vented on the rears. Ooops. Fixed it in my post. Go Baer, go Cobra or do whatever you choose. It all depends on what is in your budget, anything is better than stock!

 

[98 Saleen Cobra]

Just to confirm. I have the full out baer kit on my car. It does have slotted, cross drilled, and vented rotors. It ran me about 1100 a couple of years ago. I just checked invoice. Hope this helps

To upgrade to the cobra spec rears, you do not have to change the caliper. They calipers are the same, and the cobra pads are thinner to compensate for the thicker, vented rotor. This is why it is so economical. You just need the larger caliper brackets that attach the caliper to the axle, as well as the anti-moan braces (not essential, but does keep the noise down and leads to less flexing of the brake bracket), and the rotors. You don't even need to disconnect the brake line to install the upgrade, although you do have to pull the axles.
