Hi all,
I've gotten a couple of calls over the past few days regarding our upcoming 4 wheel 13" kit. I met with engineering last night. We are now looking at a release date of late March or early April on that kit. One of the design objectives is that the rear calipers work with our current front 332mm kit. In other words, you'll be able to add-on the rear calipers to the existing kit. The new rear caliper will be a billet aluminum 2 piston opposed...more than sufficient for the rear of the Z. This will be a version of a caliper we are building for our World Challenge cars. It will give more pad area than the current non-track stock rears, and will allow the use of stock 17" wheels (and other 17's as well). Pricing for this kit will be similar to pricing for our current 4 wheel 355 kit. It will be a bit lighter weight than that kit, and will offer more choices as far as wheel fitment, R compound tire choice, etc. Ye ask, and ye shall receive.

 

So I'll pass on swapping rear rotors!

Will the rotor be 2 piece? How much $? What other cars use this pad? I need a track version pad availability.

Count me in........IF...............(see prior messages.)

 

J Ritt....will stoptech be considering other makes for this type of kit? I'd love to compliment my front on the S4 with a two piston rear.

Ah yes, the rotors...rotors will be our 2 piece floating AeroRotor design...same as what is on our kits now. There isn't a rotor out there that will flow more air. Also, most rotors in other kits have a fixed hat...they don't allow the rotor to expand when it heats up. Based on our current pricing structure, our replacement rotors for this rear kit would be roughly $185-249.

As for pads...it's looking like we'll be using the same pad shape as the rear Brembo's on the track model.

dvlad...is your S4 the new chassis with the V8? This caliper will be put into production on other vehicles as well. I'm not sure about the S4. I can't give too many details...the WRX is a sure thing...not sure what else at this point.

 

what about that FD?

 

Thanks for the update. I'm relieved to hear that the expected release date is so soon, and that the rears will be separately available and compatible with the currently available 13" front kit.

I have to ask, though; will the front calipers/rotors that ship with the 4 wheel 13" kit be identical to the currently-available 13" front kit? Thanks again J Ritt, and a huge thanks to StopTech for responding so quickly to a market need.

Gary

 

Cool, thanks for listening to us

 

I look forward to selling some of those

 

J,

You will sell the rears alone, right? For your current customers like me that already own, love and constantly praise the front 13" kit, this is a no brainer.

Sign me up. Put me on the list. I want one of the first production sets.

P.S. Please make sure that I can get HAWK compounds in that pad size.

 

Thanks guys. Yes, the rear will be available for separate purchase. They will bolt up just like our front kit, and they will be compatible with the current front 13" kit.

Droid, thanks for owning, loving, and constantly praising. You'll have one of the first ones...i'll put it on a shelf at my desk.

I'll have to talk to hawk and see what they have in the pipeline. I'm pretty certain they have an HPS in that compound...which would work well on the street...not sure of race stuff.

Patience, patience.

VQ- RX-7 is showing up for measurements at 5pm today.

 

J- Great news I'm in the same boat as droid- you can put me down for a rear set as soon as their released. Do you have a ball park on what the rear kit will run? Also I assume the rear kit only will be available in black (mine) and red.

Thanks again for listening to all of the current 332 kit owners- just goes to show the excellent level of customer service and support you get when you purchase StopTech- I have had nothing but great experiences with the hardware and the people.

 

^^ bump^^

J Ritt, do you have any updates for us?

 

yeah any update on the FD kit?

 

So, the pricing will be the same as the 14 inch kit or the pricing structure will be the same as the 14 inch kit? If they are the same price why would anyone, except those with 17 inch rims, buy the 13 inch kit?

 

Ya, I hate to be negative, but the pricing does suck. The 13" Fronts are 500 less than the 14", I would think you would save something between 750 and 1000 for the 4 wheel 13" kit.

How much are the rear onlys?

14" 4 wheel kit, 4500
14" Front only, 2500
13" Front only, 2000

Now if the 4 wheel 13" kit is 4500 also (like you said), that means the rear only kit has to be 2500. Otherwise, I would buy the front and rear kits seperate. If this is the case, charging more for the rear is really, really dumb.

What is the pricing for the 13" rear only kit?

It's a fair bet that we're still a couple of months away. One of the design goals is that it is compatible with the current 332mm (13 inch) front kit. That means, if you really need something for track season now, you can buy the front 332mm kit and add the back later...that's what I did. I'm hoping for a late March or early April release.

As for the FD kit...that one will be sooner...possibly late Feb., but more likely in March.

The pricing structure will be similar to 14" 4 wheel kit. The reason why this kit will be as expensive (despite smaller rotors), is because the rear caliper will be a billet piece, rather than our squeeze forged model. The billet piece is more expensive to manufacture. The benefit of the 13" kit (as dictated by demand here and elsewhere) is the ability to run 17 inch wheel and tire setups...cheaper, lighter, etc. For optimum performance, the goal is to only use what is necessary to get the job done. You want the lightest components that will get the job done...that's what this kit is about. Not everyone cares about the bling factor. I care a little bit, but not enough to prevent me from preferring the 13" kit over the 14" kit.

 

Jritt,

So I guess I'm really curious now, based on the fact that the 13" Front kit is 2000, and you are hinting the 4 wheel kit is around 4500, are you saying the rear only kit is 2500? Obviously you cannot sell the 4 wheel kit for less than the sum of the Front/rear kits.

That seems to be impled by what you said about the billet vs forged construction... It just seems really odd.

I guess the 13 inch rear brake kit will be the most expensive one when it should be the cheapest. Sort of forces people to buy 14 inch and screws the people with 17s. IMO of course. I REALLY wanted a four wheel 13 inch kit but since they are way overpriced it looks like I don't want it so bad anymore. Time to shop for other brands. Thanks for all the help though JRitt.

 

Ya, if the forged rear is so much cheaper, use that on the front and back. It seems kinda silly to use a MORE EXPENSIVE caliper on the back, especially since we talking 2 piston now instead of 4 piston.

J Ritt, thanks for the info. What are some of the benefits of the billet rear caliper over the forged? Is it lighter/stronger/more reliable/etc? Does it allow for a different rotor that dissipates heat more effeciently?

I don't mind paying for quality, but I'm curious about the differences between the calipers. I am seriously considering this kit (particularly in light of StopTech's reputation for quality R&D,) but I would like to know as many details as possible about the caliper choice. Thanks!
