RPS Max pressure plate with a spec disk?

[streamlnauto]

Just curious if I would be able to use my RPS max pressure plate with a stage 3+ disk? I can pick up the disk alone for $260. The only think I am worried about is the thickness, I know the clamping force of the max pressure plate is very close to that of the Spec pressure plate, which is rated at approx 3000lbs vs. 2900 for the Max.

I am assuming this will work since other people have made hybrids of clutches before such as the RPS and DXD combo.

What would probably help would be if someone knew the thickness of the stage 3 disk?

anyone?

it can be done. The DXD however is a better clutch than either of them In my opinion.

The 3+ disk looks almost identical to the FE disk that Southbend offers, and I have held the 3+ disk in my hand and the material looks to be the same as the DXD-F.

I have had the whole line of DXD clutches, I am sure their tech has improved since then but their clamping force was not great enough to stop the wear, I had a DXD-F that did last quite a while though. I had the regular dxd, then the dxd-c, neither of which lasted for more than 5K.

The new southbend pressure plates are 2750 lbs of clamping force, 3000 for the spec, so the 2900 lb rps plate should work pretty good then.

i have heard that but havent experienced any problems from the dxd. The same could not be said for the others. Spec has the worst disk in my opinion. DXD being the best and the rps pressure plate has never given problems. Hmmmmand rps max pressure plate on a dxd fe disk would be interesting

I had a dxd six puck and it fried after about 8k. And chattered most of the way. I have a max with the street disc(Factory mitsubishi) and engagement is smooth and no slipping. You could look at the comparison and see how much better crafted the factory mitsubishi disc is. That setup is good for as much hp as a spec stage 3+. So I opted for the rps and love it. I pushing about 450hp to the wheels.

Spec's other disks may not be great but I have yet to see one reported problem with the 3+. I had DXD right when they were first being made for our cars, so they really didn't offer much for a higher clamp load pressure plate to go with it, my pedal pressure felt about 1/2 as heavy as my Spec or my RPS max did.

The thing is, MOST of these companys, SBC and Spec included are not a manufacturer, I wouldn't be surprized if the FE disk and the 3+ disk are identical, they definitely look like they are.

The street disk will not hold anywhere near as much power as the carbon-metallic full faced spec disk will. The spec stage 3+ is rated at 720 ft-lbs. I always thought that they needed to offer a higher end full faced disk for us and now there are finally a few on the market. The thing is the disk compound on a street disk does have a tendency to slip once it overheats and can easily glaze over. I know this because I have done it. But its a great combo for mildly upgrade cars. I have TD05 power now to deal with so I dont want to risk that.

actually this information is semi correct. SBC manufactures their clutches in house. Them and unorthodox are the only companies to offer ferramic material for our cars disks and sbc charges the least for it to the end user. Everyone else uses cerramic or iron. SBC has come a long way. I was the sbc test car for several of the prototype clutches when eddie was there. The clutches were good back then, but even better now. Little did anyone know that eddie was slanging clutches on the side to fund his huge meth lab. While i cannot argue with any of you about the pressure plate clamp load rating on the dxd stuff being as good as spec or rps, i can argue that for the money and the materials used in production,dxd f and the dxd fe disks are superior to all of the single plate clutches for these cars. Unorthodox uses a similar disk and the same material, but their price reflects it and most 3s people dont want to spend that type of money on that type of clutch. A spec stage 3 + pressure plate on a dxd fe clutch would arguably be the best choice for a single plate clutch due to the materials used and the clamping force of the spec pressure plate. my 2 cents

Hmm, I have heard otherwise, perhaps they manufacture their disks in house and outsource their pressure plates?

Now looking at their FE disk it is clearly a different design.

I have an account with spec, maybe I can get hooked up with SBC too.
