OK we all know who makes pads for the F, but can anyone tell me where I can get some rotors besides the dealer. :confused:

Are you looking for the stock rotors at a different price or different rotors in general?

From a quick search online, I found that Brembo makes a "big brake kit" (F brakes are already fairly large) for the F. Found it on both their website and tirerack.com.

You'll probably find that aftermarket rotors may be a challenge to find for the F due to it's limited production. The car is only a year old at this point and "most" drivers aren't needing rotors yet. For those reasons, there is not a ton of justification for an aftermarket company to offer them. But, there will most likely be some eventually. Are you needing rotors already? Consider the factory replacements, I'm sure they have worked very well. You get what you pay for.

I'm getting rid of the stock brakes and have just ordered a StopTech BBK (The supplier to Lexus for F-Sport).

I confirmed this morning that they released their BBK for the ISF and placed my order. This kit was specifically developed for the ISF. (380mm front and 355 rear) It's not a system designed around whatever parts were in the parts bin like Brembo BBK's are.

I ordered mine from Zeckhausen. I'll post an update as soon as I get it.

StopTech makes all the high performance upgrades for Toyota, TRD & Lexus (F-Sport). Hotchkiss did an independent study on all the F-Sport products for Lexus. They found that the F-Sport brakes that StopTech had in development for the ISF beat the stock Brembo's by 10 feet!

^^^^I have never heard that StopTech supplied the F-Sport brakes before, but I don't know, so I can't argue. Edmonds, however, had this to say about the F-Sport brakes:

"Lexus even finished the calipers in F Sport blue with white F Sport logos, so nobody will mistake them for Brembos. Funny thing is, they might be Brembos, since Lexus won't tell us what companies supply these F Sport parts (aside from the Bilstein dampers). All Lexus will say is that all the parts are designed and engineered by TRD. Um, that's Toyota Racing Development, as in Toyota's in-house speed shop."

They don't know either. What is the source of your knowledge? I would like to put this issue to bed because I've wondered about this myself.

I will take exception to your second comment however. Edmonds did test both an IS-250 with the complete F-Sport package. They recorded a stopping distance from 60 to 0 of 109ft. They also tested the IS-F, a heavier vehicle, on the same skid pad and recorded a stopping distance from 60 to 0 of 112ft. Not the 10ft difference you mention in your post.

Again, what was the source of your information?

Take a look at the F Sport caliper and you'll see that they have a "bridge" bolted into the caliper where you would access the pads. That is vintage StopTech. They are the only company I've ever seen that use this exact design. In addition, I saw a StopTech logo cast onto the inside half of a caliper on a TRD brake upgrade kit for the Tundra. The TRD caliper is virtually the same design as the F Sport, bridge and all. To reconfirm it all I looked at the StopTech website and compared the caliper with what I had seen. They're identical.

The test I was told about wasn't a comparison between an IS250 and an ISF. Supposedly Hotchkis Tuning did a back to back test of an ISF with stock Brembo brakes and an ISF with "F Sport" brakes.

It's good to know there are BBK's (Brembo and now Stoptech) out for the F now for those who want to have bigger rotors and perhaps a little extra bite (going to wait for comparison information on whether they're better than the stock brakes). I'm not sure how they will perform so it will be interesting to see what you think 91x08f once you get yours.

^Mike, the stock brakes on the F are Brembos. He is saying that Stoptech makes the brakes for the F-sport line of accessories and TRD.

Ricky Bobby says :" With all due respect, and I mean with all due respect", I think the F Sport kit (made by Stop Tech) will be much more beneficial to the IS 250/350.
Gains vs. cost for the IS-F StopTech kit aren't cost effective. You can achieve 9 ft. of extra stopping distance with a different brake pad on the OE Brembo kit. (i.e. higher friction ferro-carbon Hawk pad)

Man oh man, I was getting the F sport line and F mixed up. Thanks for the clarification Bulls

I would have a hard time justifying conversion from the Brembo's on my ISF. I ran them on the MSR track for 4 - 30 minute sessions, diving into the turns under heavy braking and did not experience any fade or degregation of braking. Nor was additional pedal pressure required, even after two hours on the track.

not trying to be an asx, but there are a lot of things we don't know about the comparison. 1st of all, you were "told," according to your other post, it sounded like a stoptech employee gave you the info. so you don't have first hand info at this point. stoptech may be better than brembo, but i would not confirm that info from a stoptech employee. 2nd, Hotchkis is a private company and who knows what's its affiliation with stoptech or has anything against Brembo? Do we know it was the same ISF or two different ISF's? that certainly can make a lot of difference. personally, even if there is difference, i am not convinced it's worth the money and voiding part of my warranty for a small improvement.

Ok, can we get back to the original question, has anyone found aftermarket rotors out there? I have found the stock drilled rotors can not take the extra heat from my carbotect XC10 front pads. I will tell you after 2 days of 3hrs on the track ( 1 hour at a time) on the stock pads and then putting on the carbotect pads at the next track day I felt extremely stronger braking! Now looking for non-drilled track day rotors.

Brembo makes rotors. CrazyMPG has them, a picture can be found in the picture thread under Lexus at Toyotafest 2009.

The brake kit CrazyMPG has on looks sweet!

If i'm understansing correctly, Toofire needs stock replacement rotors. I do too! I have a pretty wacky lip that i've created with the stock pads. I've ordered the HP+ from the groupbuy, and i know i'll need to change these rotors with the pads.

I've contacted Stoptech. They say replacement rotors should be available by the end of summer. I've also contacted DBA, they say they won't be making any rotors for us, but if they ever did.. they would email me.

I'm just looking for a rotor that is blank. No drills or slots please. Vented just like the stock rotors. If it takes too long before these are available, i guess i'd have to go with the factory stuff again. Anyone know how much OEM rotors are?
