warmkop, thanks for that info! To me, that's more evidence that a pad that might be considered to be an unnamed "racing pad" by a seller might actually be a downgrade.

If you're looking for a pad that's a great track compound that will do okay on the street* it's Carbotech™ XP8™ - this compound will take some time to heat up to optimal working temperature on the street, so be careful. After it heats up, it's MUCH better than the oem pads (even a moderate brake pedal pressure will throw your molars into the windshield if you're not careful. I'm exaggerating, but not by much at all - the difference will shock you.).

If you're only going to be driving on the street*, the Carbotech™ 1521™ compound will be better suited because it gets up to optimal grip temperature more quickly. This compound still has a noticeable edge over the oem pad material, but the difference isn't as great as XP8s. Another option for the street that is a slight but noticeable upgrade from the oem pads is Hawk HPS compound.

* Disclaimer: Of course, this assumes you're starting out with the Mkiv TT 4-piston front calipers, and the Mkiv TT ABS system. If you're running the n/a front calipers and/or the n/a ABS system, you should stay away from all forms of roadracing, imho (regardless of pad).

I'm watching you Phil Good to know about the EBC pads. I'll be posting a full review on the Supra I buy after I buy it. It's going to rock my world non-stop as is. Before I even think of upgrading anything in the Supra, I must get to know it well and harness it's power. After all that, then only can I look at anything more in the braking department or any other section of the car.

Right??

Good news - I found out what clutch and pads the '95 Twin Turbo Supra is running. OS Giken Clutch and Endless pads. I know those brands are very good.

Here's the link to OS Giken's website: http://www.osgiken.net/products/supersingle.html

Quote: All OS Giken clutches include a corresponding performance flywheel to ensure maximum performance and unlock your vehicle’s potential.
This means that Supra's flywheel has also been changed from OEM to a Giken.

Link to Endless' website: http://www.endless-brake.info/street-track-pads

Thoughts?

The OS Gikken clutch isn't bad, but it doesn't stand up to HARD driving that well. I have a friend that had the twin disc version in his Supra, and he had to get the springs in the sprung-hub sections replaced several times. Again, it's an okay clutch, but not anywhere near a top-of-the-line clutch for the Mkiv Supra Turbo 6spd like this one:
http://www.titanmotorsports.com/tiltripcarcl.html


By the way, do you even know if it's a twin, triple or quad-disc Gikken? Here is the list of possible OS Gikken part numbers for the Mkiv Turbo:

• TS2CD
• TR2CD
• TS3B
• TS3BW
• R3C
• R4C

Regarding the Endless pads, which compound are they? We still don't have enough information about them. Here are the choices for Endless compounds:

• LF1
• LF2
• LF3
• MX72
• CC-R
• SSM
• SSY
• NS97
• ME20
• N03W
• N35S
• N40S
• N45S
• S89F
• S90F
• S91F
• S93F
• MA45B
• ES88G

Some of these pads might be absolutely horrible, like the EBC pads that warmkop used. At least find out specifically which pad it is, and then after that we can discuss how well they fit your application.

The Tilton clutch seems good but, is VERY EXPENSIVE and is aimed at very high horsepower figures. A good single plate clutch like the Giken should handle up to 500RWHP possibly more? No, I don't know how many plates - need to wait for them to tell me that. Do you know if the Giken clutch outperforms the OEM one?

What do you think of the brand Endless??

It's all relative. For example, compare it to this clutch:

No - again, the sprung-hub design is a weakness...and that design feature is for comfort and reliability NOT "very high horsepower".

Didn't you read the information at the link you yourself posted? Gikken doesn't make a single disk clutch for the Mkiv Supra Turbo. Why ask this question?

Please note that all clutches have a single pressure plate. It's only the number of clutch disks and floater plates that vary.

Of course it does, but most of the reason for that is that it is only offered for the Mkiv in multiple disk versions.

I'm not aware of anything wrong with that brand, I suppose. However, talking about the specific compound of pad installed on the Supra you're considering is more relevant. A compound that's great on the track can not only be 'bad' on the street...it can be dangerous. For example, Endless' S580 pad material wouldn't just be a bit dangerous - most likely you'd wreck your car with it. It takes a lot of hard braking just to bring that pad up to the temperature where it grabs. Before that, it feels like the pad is a solid stone and has almost no grip at all on the rotors.

To be honest though, the overall relevance of pads to the car purchase is a secondary consideration at most. Brake pads are consumeables, just like gasoline, oil, and transmission fluid. Is the exact type a consideration - sure...but only for the period of time until it needs to be changed. Many of the other parts on the car (eg. the brake calipers) are meant to last for many years or for the lifetime of the car, and that's what is of primary importance to evaluate.

Lastly, the question is a bit weird. It's kind of like asking if I like General Motors. I guess it's an okay car company in general but I wouldn't use a C6 Z06 to drive my grandmother to a ballet in the wintertime. I also wouldn't be caught dead in a Cobalt. *shrug*

And the difference is...?

But that clutch can handle 800HP...if that's not a very high figure to you, I don't know what is...

Yes Giken doesn't, sorry, my bad If the Giken is better than the OEM clutch then, that's all the better for me...

So tell me, why does the Tilton clutch description speak of "multi-plate" clutch?

Yes, agreed - the pad compound is second consideration - hence I haven't stressed about it. When I get the car, I'll look at the pads with an "if the shoe fits, wear it..." approach. If I'm not happy with them for my application, I'll buy a new set...

What did/do you think of the OEM pads through your personal experience?

For starters, the price (and yes, that Tilton all-carbon clutch is very much worth the price, imho.

800hp=680rwhp. No, 680rwhp is NOT a "very high" figure for the Mkiv Supra Turbo. 680rwhp is achievable with the oem fuel system, methanol injection, and a small-to-mid-sized single turbo ... which is a rather modest configuration quite honestly. Truly impressive Mkiv Supra dynos are well over 1,500rwhp (which is >1,750hp) these days.

Why wouldn't it? It is a multi-plate clutch, so that description is completely accurate.

Good (but not great) braking power, low noise, moderate rotor wear, relatively high amount of brake dust.

Ok then. Please stop talking about "racing pads" since you agree that factor is secondary at most.
