StopTech brake kit is nearing completion...
 

Hi guys...just wanted to give an update. The StopTech BBK is nearing completion. Engineering parts are off of the drawing board and into production. The initial offering will be a floating 2 piece 332mmx32mm slotted Aerorotor (drilling will be $50 more per rotor), mated to our ST-40 squeeze-forged calipers. The kit will ship with these parts, as well as our own DOT compliant stainless front lines, Axxis Ultimate pads, and all associated brackets and hardware to bolt it on. It will work with all of the factory componentry in the rear, master cylinder, etc. This is the exact same setup that many of our race cars use, including the Istook/Aines Audi S4 in the Grand Am series.

Pricing for the kit will almost surely be in the $1795-$1995 range depending on options...this is where you all come in. Would you rather see a black anodized caliper at the lower price, or a painted caliper at the higher price? We may just keep the line simple and start with one...so please state your preference if interested. Then again, we may offer both...not sure yet.

We already have a chart up to check your wheel fitment.
You need to print this template out, check with a ruler to see that it is to scale, tape or glue it to a manilla folder or cardboard, and place it inside the wheel. The directions for use are here:

We are moving forward with a front-only kit to begin with. A 4 wheel kit could be a possibility in the future, depending on demand, feasability, etc.

Feel free to email me at jeff@stoptech.com if you would like to be put on a list for updates. As far as a timeline goes...we should have engineering parts on a car within 3-4 weeks for testing. Production version will be released shortly after the testing is complete. I think a realistic expectation is that we can have parts on your car within 8 weeks...just in time for Spring and track events. :D If anyone wants to place an order...this time frame could shrink... :)

I'm doing my best to get it done guys. Thanks for your patience, and let me know if you have any questions/concerns.

Every time I see one of your posts, I visualize you holding a steak at some wild crazy wolves. haha

Question. If the drilling is an added service, are the rotors designed/engineered so that the drilling of holes will not cause excessive stress to the rotor (such as increased possibility of cracking)?

I would strongly vote for the lower-end annodized kit for several reasons:

1. Annodizing offers no performance disadvantage, and still looks great.

2. You can always paint or powdercoat a set of annodized calipers if you want to, to get the higher-end look, but you can't work in reverse.

3. At almost $2,000 your kit will have alot of competition from AP kits and such. At $1700 and change you're significantly undercutting most of whats out there, with no degradation of performance.

Anodized black or satin silver..

Anodized Black sounds good..

yeah black or silver NOT red like everyone else

I want my calipers red with the "stoptech" letters in white. That would look bitchin with my black ce28ns.

DomFD3S,
Heh...that's pretty much how I feel! :D You know how FD owners are about their cars...fanatical probably is an accurate description. Now imagine people with M3's, Supra's, 350Z's, Porsche's, Civics, and Pintos all harrassing you to get them the perfect products for their cars...that's my general day-to-day challenge! It could be much, much worse though...since I'm a car nut too. :cool: Even the Pinto guys need brakes! :p

As for the drilling...we don't recommend drilled rotors to anyone for anything other than street or show. I don't care what anyone tells you...they will not hold up as well as slotted under stress. To my knowledge, we don't have a single pro race car running drilled rotors. If you want performance, go slotted...period.

ptrhahn,
We just may have to offer both kits. That will solve the problem, and still give show guys the option of paint.

It's interesting...people are fairly sensitive to a couple of hundred dollars on these things. Personally, I spend the extra little bit for the best product, but I can understand that people are stretched and on a budget...particularly when they get hit with the mod bug and start the downward financial spiral! :D
I'll do my best to keep the price down as low as possible.
I've done some research on prices...the AP 4 piston kit is around $2595...substantially more expensive...I'm not even sure if it has floating rotors. The Wilwood 6 piston is $1495, and not even in the same league from a performance standpoint (or aesthetics IMO). Other cheaper kits out there are cobbled-together with various parts, but will not offer the same heat capacity or performance for the $. Also, you have to consider replacement parts and service. We have roughly 20 pad compounds that fit the caliper in this kit (street and race), and our replacement rotors are very reasonable vs. the comptetition ($195 each for slotted). This kit is going to be the hot setup. :)

Black anodized and black painted come with white logo. We also offer red with white logo (red/white), and silver/black logo. We do blue/white, and yellow/black for an extra fee. The silver, blue, and yellow calipers take about a month to process...red and black are typically quicker.

RX7 Rage...check out this car to see the red under black...http://www.stoptech.com/productphotos/300zx/300zx.htm It looks bitchin. :D

Anything that works.....but, don't forget 355 rotors.

I'd like a 355mm 4 wheel kit like the Z. :D

I sent you a PM.

Thanks,Sean

You better be offering a 10% discount if you are planning on cornering the market!!! :D

Ha Ha.

Anodized black. Keep it simple and cheap. Anyone is capable of painting theirs any color they wish with just a little effort. OH and Don't forget about the rears. I will be waiting to see what you come up with.

The quality of the kit seems very good for $1800. I think offering both painted and anodized calipers would be best, but if you can only go with one, go with the anodized. I do question the spec'ing of the Axxiss pads, because absolutely no one is running those on the rears. Most people with aftermarket pads are running Hawk HPS, Porterfields, or EBC's. I would think offering one of those pad sets would go over better. Excellent looking kit though, I will be excited to try it out on the track later this year.

BTW, for those of you asking for a 4-wheel 355mm kit like the 350Z, PLEASE! Our car doesn't weigh 3500 lbs, we don't need rotors that large...:)

Ya think - When will people learn!

Black anodized is fine with me (you can't admire the calipers while you're whizzing past the 200 meter marker braking into a downhill second gear turn from a 145 mph straight), and I agree with Rynberg on the Axxiss pads, if you could offer them with Porterfields (which I like), that would be great.

Jeff, I don't have a printer handy at the moment, but I will be taking that template to my Fikses soon. The 332mm kit better fit or I will be bummed! :)

StopTech's measurement of the center bore may be incorrect (per 1RedR1and1RedPEP). Jeff is looking into the situation and I'm sure he will get it corrected ASAP. Just to FYI.

1. The Wilwood 6 piston not even in the same league? Care to back this up with some factual data?

2. Are you supplying stainless steel lined pistons with these kits?

Anyone want to buy an AP 4-piston kit? :-) I may switch to Stoptech's setup! (Esp. if you come out w/matching rears later on, hint, hint.)

Very good points, Clayne.

The Wilwood Superlite's use 13-inch rotors, fit the stock wheels and are available with the SS-lined pistons. The only negative I've heard about them is the fact that they lack dust seals, leading to more frequent rebuilds.

Now, aesthetically, I will agree that they are not in the same league....:)

Thanx, Dom. I'll wait for the "corrected" templates. :)

If the Wilwood kit people are talking about is the one from M2, the price once the SS pistons are ordered isn't really much less than the $2000 Stoptech wants for the painted calipers. Well yeah, it is a few hundred dollars which would be the equivalent of the anodized version. There's also the usual wait associated with buying something from M2 that must be considered.

I'd say that $2000 for the Stoptech kit is a pretty reasonable number given what a typical AP-based kit from say M2 or N-tech runs for. $1800 would be even better of course, but either way it's still rather significantly cheaper than going AP.

I talked to my engineers about the measurements a minute ago. The drawings are correct. The potential 'mistake' is not a mistake at all. The factory wheel register is the number shown...that is the standard on all of our fitment charts. The factory center bore is 72mm as 1Red said...and that's what the hat will be designed to fit. That's something I didn't know...you learn something everyday! I guess that's why God made engineers. :p

Hawk HPS is a good choice, but we recommend the Axxis over all of these. We ship them in every kit we make. They are an outstanding street/autoX pad. We are no longer selling Porterfield. I wouldn't touch EBC with a ten foot pole. I used them once on my relatively slow and light integra type R on the track (the green and the red compounds). The damn things fell apart immediately...worst pad I've ever used. I think they were adequate on the street...meaning equivalent to stock or so. Bleh.

Sure. Check out this link:

We tested in-house the deflection of all popular calipers on the market. The Wilwood aren't represented by any of the lines on the chart. Do you know why? Because they flexed so much at such a low pressure, that we didn't even include them on the chart as a competitor! It is widely known that Wilwood has the most flexible caliper on the market. Dust seals are nice to have. The Wilwood calipers are not in the same league.

You are posting this as a benefit...not sure why you believe that is a good thing. I spoke to my engineers about this very thing about a month ago. The idea behind having all-aluminum pistons in an aluminum caliper is to maintain tolerances. Stainless steel and aluminum have different expansion rates when heated. You wouldn't want to materials growing in your piston and calipers at different rates...tolerances disappear in a hurry! There has been experimentation and implementation of titanium by some companies...we've toyed with this as well. It's tough to get it right for this very reason though.

I wouldn't plan on seeing a 4 wheel kit unless there is massive demand. The engineering effort may not be offset by the return at this juncture. I'm just trying to be realistic. I think you'd be happy with the front kit anyway. :)
