Do you have any pictures of how bad the fitment is?

 

 

If you flip that caliper adapter so the ear is away from the rotor will it line up better?

 

Negative. The adapter won't bolt to the hub any other way.

Conveniently, the vendor is so unwilling to support his product, he sent a return shipping label today. I don't know what happened, but I'm not sure anyone has ever got it to work.

 

Darn i just bought a set of 17z calipers also but autosport said they dont have in stock because they dont have a big enough order to produce. They also said its not their specialty.

 

I hear there are a couple more companies that make something compatible. Worst case, 17Z is extremely popular in the Audi/VW market and you could sell. I'm gonna spend some more effort prior to selling. I have 2 sets of them, both already powder coated, and 2 sets of OE IS-F rotors. Argh

 

Do you have the driver and passenger sides switched?

 

The hub holes are threaded. This gives a possible 4 mounting arrangements. Any other way makes the problem worse.

 

You cant just swap calipers without doing the proper math to see if they are making things worse or better. Brake Bias can go out the door quick, and in fact can be very dangerous. I'm sure you can find a Brake bias calculator out there to help you with this.

 

Genuinely puzzled what bias has to do with a part not fitting ??

 

Any update here? Did you get them to work?

 

Nope. Never got support. AE refunded.

I've since designed adapters that work.

 

Autosport Engineering (Florida) are terrible. I bought billet valve covers off them a few years ago which did not fit. The quality was tragic. After a lot of wasted time and him sending another faulty replacement, I binned them. No refund was given. I would steer very clear.

 

I have the kit that uses the cts-v, corvette, camaro calipers from them. Fitment was spot on no issues.

 

Happy they fit. It's a much simpler adapter. The post was about the 17Z calipers. It's a fairly complicated adapter to align everything. AE was selling a product that didn't fit. He also couldn't find a single picture of the part actually installed on a car. I believe he's since removed them from the site. After 2 cars worth of brake kits (calipers and powder coat, rotors, pads, lines, etc) and weeks of excuses, he just refunded them. Was a really disappointing process.

I've since designed and machined proper adapters. May or may not sell a few sets.

 

I would like to see how well the brake pads contact the rotor on your CTS-V setup. I'm seeing some gaps pad-to-rotor contact that could be improved either by stepping up a 15" rotor from the RCF or repositioning the caliper. My CTS-V setup is from the forum member Tarmactr

Please share, if possible.

Hey mooose14, if you could please fab me some of the adapter brackets I would gladly pay you. I have a set of 17z calipers front and rear, and would like to use them on my car as well. You would be a huge life saver. Please let me know if you're willing.

 

 

Thought I would update this thread. My adapters are finished. These work with Brembo 17Z Calipers and IS-F 360mm Rotors. Zero modification to Calipers.

 

Hey Moose14, will you be selling these adapters?

 

Sick, those look great.

 

OP, if you're going to sell these (which I think is something that will benefit the community), you will need SF approval to do so. If you are desirous of such approval to prevent your threads (where member to member sales are offered) from being deleted, you need to contact a member of the mod team requesting such approval.

Thank you.

I updated my post as not to indicate they are for sale. Seems I don't have the post count to post in the for sale section. Thanks for warning in lieu of just deleting.

 

You will need a total of 30 meaningful posts before you can post in the For Sale section. You have already been a member for the requisite amount of time (30 days). Going forward, LMK if I can be of assistance.

This sounds like an awesome option and I’m interested in a pair of brackets. Let me know if/when they are being sold.

 

Send me a message.

 

So how do all these calipers compare in performance?

The Brembo srt8 vs f50/f40 vs z17 vs corvette vs stoptech st60/st40 etc etc.

Heard some great feedback from recent Ksport users as well.

Honestly, the TT Brakes with good pads are really sufficient. The GS430 brakes are great too. Moving to any of these BBK's is, in almost all cases, overkill. That said, all of them have their pros/cons in terms of cost/weight/ease of install/etc.

I use the big brakes on my street/roll race car because I want the additional pad surface area as to not need to really stand on the brakes at 160-180. I would probably select none of these brakes for any kind of racing that isn't in a straight line. For that purpose, I would likely go with a lightweight caliper with readily accessible maintenance parts and purpose built pads. Likely Alcon/Wilwood/Race Catalog Brembos. Other than a small number of people that drift supra's, it seems the big majority of owners (that race) do drag/roll racing.

So to answer your question. I think it would be difficult to really judge the performance differences of all the BBKs on a Supra. All of them would substantially outperform OE calipers from 25ish years ago. It's probably worth mentioning that the calipers alone are not a recipe for success. There is a substantial amount of science behind the optimal piston surface area ration between front and rear brakes. There is also science to what bore master cylinder to use for said piston surface area in order to produce the appropriate line pressure. Add to it the further complexity of picking the ideal pressure for the application. In racing, most of the time, the idea isn't to stop, but to slow down. Even slowing down is a science. You may not want to slow down too fast for a particular track. In the end, I would speculate that the majority of people switching to a BBK is primarily cosmetic and justify the cost with the perceived increase in performance. I, for one, think a giant caliper and rotor behind a good looking wheel is how modern sports cars SHOULD look. Maybe not for a classic or the MKIV purist. Apologies if I strayed too far from topic My 2cents.

 

Any issues with the adapter hitting the LCA when steering??

What about the rear? Any solutions?

Nope. Everything fits great. No grinding like the CTSV kit. Just bolt up. I do have rear 17Z, but my preference for rear brakes on Supra is Evo 8/9 Rears. Evo X requires opening up the holes a little to work so I'm working on an adapter so nobody has to actually change anything.

 

Other than the brackets and rotors, do the brake lines just line up or do we need SS lines with specific banjo sizing, lengths etc?

 

I recommend upgrading to a stainless set. Quality lines can be had for about $60. Otherwise, yes, the OE fit is fine.

Sick, I've PM'd you but man, I would love a set in bronze/gold!

 

I grabbed a set of these adapters a few months ago and finally got my calipers back and prepared for install. I went with ebc red stuff pads. They look great, I think. They fit perfectly behind my ccw c14 wheels (which are gross currently - when the car is back on the road that’s one of the first things on the list to detail)

 

Just got my brackets too and am now waiting for my wheels, should be another couple weeks, cant fit these behind the stock wheels haha

 

Hi, I would be keen on some or the measurements to get them machined here (on the other side of the world in NZ so shipping is usually more than an item!).

 

I've shipped to NZ before. But it seems shipments from US to NZ have been suspended. Send me a message and we can work something out.
