so where can I get the brake lines from? and how much do they cost?

and who will do all this installation? can a lexus dealer do it...will they do it?

I think this is a good way to not only get brand new rotors but you get them slotted and cross drilled w/the TRD metallic brake pads & stainless steel brake lines....and it doesn't cost too much either, neither is it geared for only racing use !

To tell you the truth, I know you guys may be disappointed, but I hardly ever even floor my GS. Yeah I don't use it to its full potential, sometimes I think I am pampering it too much! But anyway, today I floored it, it was awesome, we have a place where a small road intersects with a city highway (55mph limit) and ofcourse there is a stop sign at the intersection. As soon as I saw a fairly clear path, I turned and once in the lane at about 10mph, I floored the beast! It was amazing, the rpm went up to 6.5 and then changed gears, and then 6.5 again and changed gears, before I knew it, I was close to 70, so I slowed down. I hope I don't get too used to this though! :eek:

But I just LOVED the amazing feel of power and speed, sometimes when I do that I wish I was in the car right next to the GS just to see my GS fly past me...hardly anyone around here has lux sport sedans, and even if they do, its old people, so I don't ever get to see a good car race, oh well....

 

Just checking how many people would be interested in the above components listed? The only change would be that the rotor would be a slotted one from TRD, Steve mentioned that there isnt a direct Brembo replacement for the stock Supra rotor. Im sure Steve would love to hook us up if enough of us are in the market.....
The most knowledgable brake gurus that we have as resources for information on this site(Manaray,Miguel,etc.) have already stated that this is definitely an awesome improvement over stock, especially for the price....and that short of going for the AP racing or the ENTIRE Brembo kit, this is as good as it gets!!...Im in if any one else would like to start a group buy?
Again, this is the Supra TT caliper with the TRD replacement rotor for the Supra caliper...(also trd pads, and SS brake lines)

 

This should go in suspension/handling section.

 

Porsche's and Ferraris also come with seriously oversized brakes and have other features (weight distribution, etc.) that help overall braking...I wonder how much better a Porsche or Ferrari would stop compared to a IS300 with a big brake upgrade...

Also, AP Racing has been more of a race brake company. They only recently started making "street" applications. Brembo has been a long time "street" vendor to various car brands...as far as being "race proven", AP Racing has won championships on McLarens and Ferraris...If you look at the DTM, TOCA Touring and V8 Star races, you'll see that AP Racing is on the winning cars...as for "durability", AP Racing is the first brake system that require no change of disc or pads during the 24 Hours of Le Mans in 1999 :eek:. And AP Racing is also standard equipment on all division of American Stock Car Racing...

Also, I don't think the guys over at Stillen would really lie. Since I have a sponsorship deal with them, they could care less WHICH brake system I got so long as it has a STILLEN logo on it (I know this because they ASKED me which system I wanted to do). The price difference isn't much and in asking them and researching on my own (asking various shops that have done both setups plus some web searching, talking with various techs, and emailing a LOT of companies including AP Racing, Brembo, Alcon, Brabus, etc., etc..) I came to the conclusion that the AP setup was the better of the two.

Granted, I'm not "racing" my GS...but when I'm burning up the canyons, I want the best brake performance possible (within reason of course!).

Since I don't have a "stock" GS with just a brake upgrade, I can't really compare it to a stock GS with stock brakes....but do you have stock brake distance measurements (from a magazine or whatnot?). I'm interested to compare my setup (with the brakes, the wheels, the suspension mods, etc.) to a "stock" GS (430 or 300)....

The whole ABS factor is interesting, do you have 60-0 numbers or 100-0 numbers of your own? I'm going to test mine out as soon as I can find a safe and secure testing spot...of course, I know this isn't a 100% scientific test, but at least we can get some general ideas...

 

SO IS THERE GOING TO BE A GROUP BUY FOR :?
1) BREMBO ROTORS FOR SUPRA
2)SUPRA TT CALIPERS AND PADS(TRD)
3)SS LINES (ROD MILLEN) OR WHOEVER..

IF YES, I'M INTERESTED IN KNOWING HOW MUCH THIS WILL COST....

***OH YEAH.. SORRY TO ALL THOSE ASKED FOR PRICES FROM ME BEFORE,
BUT MY SOURCE FOR PARTS FLAKED ON ME BIG TIME....***
SORRY

 

The majority of Ferrari and Porsche models, probably excepting the 911 Turbo and F50, have essentially the same Brembo F-40 kit with solid discs (which don’t differ much from the 13” diameter). And yes, rear weight bias helps a lot in braking.


Agreed...Brembos are better for the street, AP better for the race track...

Me neither, but it would be nice to see the actual test results to support such claims, any serious company should do that.



Great idea, but I wish I had a Gtech meter (not sure on the correct name) or similar device to get reasonably accurate results.

 

Oh, another piece of information that I found out (but forgot to post)...

The Brembo rotor is 32mm thick...the AP Racing is 35.5mm. I remember you comment a few posts back (this is directed to Miguel BTW ) that you said you saw both systems side by side and you came to the conclusion that the Brembo system was apparently more robust, I'm curious to know what made you think this? The AP system uses a larger rotor, a thicker rotor, a larger caliper, etc., etc...

As for test results, I'm going to get some information from Stillen...

I don't have a meter either...I was just going to so some informal testing

 

Guys,

I didn't know I was missing out on this thread!

Anyway, I am looking for replacement pads for my AP brakes. I bought my brake kit through Stillen. The list price for the pads are $369! For ref, the Brembo pads list at ~$320.

KVR Performance products in Canada has replacement pads available. These pads are available in various compounds in the Hawk pads. The prices below are in U.S. Dollars and do not include shipping.

HPS $217.00 (high performance street)
HP Plus $231.00 (agressive street + low level racing)
Blue $320.00 (road racing, rally)
HT10 $403.00 (severe duty, Nascar, sportscar series)

Would the HP Plus compound fit my needs? I don't race my car, but attend hi performance track events at race tracks. I like the stock pads Stillen provided, but I get a lot of brake dust. I have attended ~8 days of track and ~15k total miles with 35% left on my stock pads. Would I see the same durability with the Hawks, and hopefully less dust?

Any other sources and suggestions?

Thanks.

 

I'm also very interested in the brake kit. As long as it's cheaper than RMM's one.

 

Not getting enough sleep huh? As I explained before, the APs have a much bigger air gap than the Brembos, so most of the 35.5mm are not iron but air. The Brembo disc faces are roughly 1.5 times thicker than the AP's. The added thermal mass benefits heat dissipation, deformation resistance and durability. I didn't mention this before but the curved vanes inside the Brembos are also thicker, again, more robustness can be found on the Brembos.

So the AP's use larger rotors...in a way yes, but they have less iron than the Brembos...again, total rotor thickness and diameter can be misleading sometimes..."Larger" isn't always better under all circumstances..

APs having larger calipers...again, the number of pistons can be misleading. The total piston area is higher on the Brembos despite having 4 pistons. And also, the Brembo calipers ain't physically smaller than the AP's In fact, the Brembo calipers are a bit heavier (being the same material-aluminum).


Etc, Etc...Well, I haven't been into here yet, but now that you mentioned this...IMHO the overall quality of the Brembos is visually better, the paint, the finish, the logo, the details... Some other benefits I found on the Brembos:
-The dust seals are a lot beefier. (not an issue for racing - under these conditions the seals could dissintegrate)
-The compliant disc fasteners are a work of art, they have integrated springs to compensate thermal expansion. I didn't see those on the APs.

 

Alright everyone, if you could do a scoring system of all these different brake upgrades, what would the AP Racing system earn out of a 100 (100 being perfect, stock GS brakes being 0)?

And what about Brembo & RMM? and all the other different kits? It seems as if there are more than half a dozen different kits, but not only do I not have a clue of their prices, I don't even know how effective each one is.

Seems as if AP Racing would get a score somewhere in the 90s....

Manaray, Mean Gene, and all others, inputs on a "score system?" And I know there are different systems for the track and different for the street, but I don't think it would actually be "bad" to have track brakes on the street....a score and price list would be nice to help people like me determine which one is the best one and how much better each one is than the other. I know not all of you have probably tried out each and every brake system, but still, according to what you all have read and researched and experienced...

I hope bitkahuna or anyone doesn't call this a "stupid question"!

thanks in advance

 

Miguel - Hmmm, interesting...then I wonder what AP's reasoning is to use such a setup. Considering that track use is more "abusive" than street use, I can't imagine AP would make anything less than a "substantial" setup. I suppose what you said about brakes being a science in themselves is what it comes down to. The choices that AP made for that brake system must add up somewhere down the line because everyone I've talked to considers it the "ultimate" setup...oh, I'm working on getting some numbers from Stillen...

Nano - I don't think we could accurate put a score on any of the systems...and I think people would have their own opinions...

If it were my list, here's how I'd rank them...

1) AP 6 Piston Setup
2) Brembo 4 Piston Setup
3) RMM (only because it doesn't say "Supra" on it!)
4) Supra setup
5) TRD Pads w/Slotted rotors
6) Stock GS brakes

But in all honesty, I think for "most people", the Brembo setup would be MORE than good enough (the AP setup being a little overkill for "most people")...I think with the RMM and Supra setup, it will suffice for "most people"...especially since they're 1/2 the price (or about 1/4 the price in the case of the Supra setup)!

Now remember, with most of the brake systems, you're stock rims probably won't work w/o some modding (spacer, shaving, etc.) And many aftermarket rims (especially cheap ones) won't work well (unless they're designed for big brakes)

I, for one, can vouch for HRE's rims...I have about a 1/4" of clearance from my spokes to the caliper. No spacers, no shaving, no bull****. Straight up bolt-on...Model 543 in 20" x 8.5" with a +37 offset...

 

OK, if I have been reading this correctly, the following people are intrested in the SupraTT brakes:

-Myself
-GS4Will
-blingIn300
-Racing Aristo

I just want to say again, this would be for the SupraTT caliper, TRD/Kazuma rotor, SS lines, and TRD or stock pad. Brembo doesnt have a direct replacement rotor for use with the SupraTT caliper....
I have never engineered a group buy, but I would assume we will need at least 5 people to be able to expect Steve to give us any sort of price break....Once we have 5 people interested, a simple call to Steve should get this rolling...Thanks, Tiny

 

I've seen people selling Brembo rotors for Supra. I could easily buy them from some online shops, ebay for exmaple. Could someone explain it to me?

 

Dennis,

you are right we talked about this before, just get the Brembo rotors that are designed/made for the supra tt.
