Note: You can reuse the pads from your SC calipers because they are the same as the ones used on the Carrera brakes.

Ah, yeah . .. that changes things. Planning for tires is not what i read.

What I had read, was that he was that he had no problems, has a now lighter car, AND found braking improvement with those extra 4mm. (!?)

--extra cost,
-- extra rotational and unsprung weight

-- knowing that it solves a problem that doesn't exist . . . but might solve it if it did exist --because bigger must be better. ...priceless?

I should have been more clear Island. I was having brake issues, my SC brakes were cooked not only through the dust shields but the freshly rebuilt calipers had become stuck in less than a year of use. So I guess I did have some brake issues, but I was under the assumption that overheating brakes were more akin to fluid boiling problems which I never had. It was hard and firm the whole session, infact I could finish and run another session and it would be just has hard. ;)

Plus, if I was all about the show I woulda painted those calipers pink or magenta. :D

The Carrera rear pistons are a tad large and need to be toned down, the factory 33bar p/v that Kevein showed you is the stock one on a Carrera, an adjustable one would be a nice touch.

You can run w/o the p/v by just doing the Carreras on the front and leaving the stockers in the back. The front is the place that needs the help.

Bill, I know you are a wealth of knowledge here. Can you point me in the right direction for a adjustable p/v? Are there some good threads on this? What is the cost like? I woulnt mind an adjustable one if the cost allows for it.

There are all sorts of them they run ~$50 - $100 new
If you want you can have this new, never opened the bag, thats been sitting here for a while. $25

I'm repeating that for emphasis. The fatter rotors aren't really needed on the rear and if you do them you must do the PV as well.

You can drive the car as is now but I wouldn't track it. You'll find those who say you can but the rears will be prone to locking up.

Bill, that bad boy looks great. I would rather it in black but for the price I cant argue. lol. (sent you a PM)

What else is needed for the install and where/how do you install it? Im sorry for the 20 questions but this isnt something im well versed in.

Bill, I also saw some that offer gauges with them when I was searching online. Is adding a gauge in line with it recommended or useless?

Tod, thanks I hear you. I definitely want to finish this all up before I hit the track.

For those of you wondering what valance I am running, I think we got some answers.

Pretty much useless, some of the pros mount ports on the different circuits when they do development work. But the drivers feel is the ultimate determinant.

Kevin,
Why is the prop valve needed? Is it a matter of piston sizesor weight, sc vs carrera? Thanks. Paul.

The valve is a pressure limiting device that limits the amount of hyd. pressure applied to the rear brakes.

The Carrera rears have larger pistons than the SC rears, and apparently under heavy braking (like when you're burying the pedal at the track) the rears can lock up. That's not what you want to happen.

Bill can explain the details better than I. I just know how to swap parts and read message boards......... :p

Thanks Noah,

I have no clue on the mirrors, all the real body parts of my car were on long before I bought it. They fit excellently though one screw did come off on I-94 at 80+mph leaving the mirror flapping for its life! haha. Since I have used epoxy to hold the mirrors on as well as the backing screw but when I had them off I didnt notice any kind of marking or stamping. Sorry bud.

Nice work, Matt!

She is a beauty - so why the gloomy look ? ;)

They also make a 55bar p/v unit, that's what I'm using.
j.p.

That's not a gloomy look, that's a 'I'm cool, heroic, tragic, and suave all-at-the-same-time' Jack Olsen kinda look.

Nice work Matt, now you get all the benefits of the bigger brakes without the @#$%! brake pad wear sensor nonsense. Plus, you're assured of further tinkering with the PV!

Thanks Ianc! Yes, that is the look of a man who is victorious after a long night of battle with rear caliper bolt access. :D

Im really excited for getting everything back set up for the track. People have been giving me a hard time for going with an adjustable P/v but the way I see it it was just as cheap as the stock type ones and gives me the ability to mess with the bias especially because I run less weight over the front brakes due to not running a spare tire. But hey, if I end up leaving it at the stock type setting, im out five extra bucks.

You could try the brakes without the P/V installed. I've been racing for 4 seasons that way. There maybe a little more rear bias that optimum but I think it's closer to perfect than the stock SC brakes are.

Try it and see what you think. Just be aware of the extra rear bias the first time you brake real hard. If you find it's too hard to handle then you can put the P/V in.

I was following up on this older thread which helped me out with finding and installing the Carrera PV I sourced from another Pelican.

My car started life as an 83 SC. The PO of my car had put 964 calipers on the front, carrera's on the rear with carrera 24mm rotors all around and had not upgraded the MC. Based on Bill's advice, I pulled Carrera fronts off another project, rebuilt them, sourced the hard lines and PV from another Pelican for a whole $50 bucks and got it all bolted up on Sunday. I had run without the PV for one track day with softer rear pads but still didn't like the feel of the pedal and it seemed prone to early lock up in the rear.

How has your setup performed over the last year. Any issues with heat build up, etc.? I do have cooling ducts to the fronts.
