A couple of things here guys..
BBK's give your car greater resistance to fade by absorbing and shedding heat more efficiently. Racers upgrade because stock brakes were designed for a single stop from high speed, not repeated slow-downs with little time in between to cool off. Where the Endless, Winmax, Project Mu shine is endurance races with the proper racepad, and most importantly the correct tire.

You also have to look at the size of each caliper. The Endless BBK is huge as are a lot of other brands which will require you to use a low +30's offset wheel. But when you do that you can no longer use your OEM fenders if you have any sort of drop. Why? Because you will damage your front fenders. Most people go with Spoon or Brembo because you can get away with mid to high +40 offsets and wheels are a lot easier to find with these smaller calipers. Not to say they are a cheaper, more of a junk caliper.

What you also have to realize and some of you have stated it already; Proper tires and race brake pads with the Endless BBK in an endurance race or any race over 5 laps will outperform Spoon, Brembo, etc... with equal tires and pads. Its been proven.
Your paying for the name and rnd with any of these calipers. Is $3750-$6550 a lot for a BBK? I think it is. But if your car is a show car and you have the money then have at it. If your car is a dedicated track car then I honestly would give these a shot vs your run of the mill Spoon/Brembo setup.

I have heard a lot of complaints from track junkies regarding the Spoon calipers fading over time with more and more laps on them. Brembo I havent heard any bad stuff.

Stoptech is also one of the best calipers IMO for the money. I dont believe there is a better performing caliper on the market right now under $2000 that can compete with Stoptech.

 

Yeah well i think we have established the fact they are bigger (obviously, J's race car has wide fenders already JsAP1) and they resist fade better but I have never seen the J's car use them. Not in the lap race with the AJ race car and not in any best motoring that i have seen which have come out since the brake kit has been out. And i don't think there are rules against it in a togue race cause the amuse car uses Endless (Amuse) brakes. That said, Does anybody know if it will clear 17x8.5 +25??????????

 

You should be fine with that offset and wheel. I have had Endless calipers for a couple years now and Spoon calipers, etc. They do have wider fenders but didnt for a long time.

The pricetag of the J's Racing calipers is probably one of the reasons nobody is buying them. They are $4300+shipping as opposed to Endless which is the same caliper for $3750.

We actually knew about these J's Racing Caliper 3 years ago before anyone on this board knew about them. Actually my friend SSmugen went to Japan in 2002 and saw the prototypes and sent me pictures and Js told us not to post so these have been in the works for 4 years already. Js Racing also had a full CF 1x1 weave valve cover that was going to sell for $1200 but it never came out due to cracking issues over time. Ben (AJ PWR) and I talked about this valve cover years later and he told me the same thing. Cracking issues pushed J's Racing to scratch it.

 

[QUOTE=bluesaint,Dec 21 2005, 06:01 PM] because spoons are lighter.

 

Now the next question is how would this same J's Racing car match up against one of its rivals, ASM to be exact, on lets say the famous Tsukuba track and shoot for 25 laps. One with the Endless calipers and racepads and one with the Spoon/Nissin calipers and racepads. What caliper would fail first? My money is on Spoon/Nissin failing first. I think there is a reason the ASM S2k uses the 6 pot Endless system...

Dont get me wrong, I like the Spoon calipers, I have owned two sets, I just think the above question holds some truth.. Come on Ben...

 

You can fit CE28N 17x8.5 +50 offset with no spacers to clear both calipers.

Just a few pics show you guys that I have for the J's calipers

 

Awesome info guys, especially that last post. I didn't think 17x8.5 +50 would clear the endless but now we know! Thanks guys

 

Cant wait to fit my J's Racing BBK fitted, BUT I have also the option of fitting the Endless BBK as well which is in stock in Greece at the moment. The only thing that puts me off for getting the Endless BBK at the moment is the fact that they are only in red colour (in stock) at the moment.

By the way, can you confirm if J's Racing BBK comes with blue calipers as well?

Thanks.

 

I was just watching a speedvision show, I think it was called sports car revolution and they were doing a build up on a rsx and they put and intake and exhaust and header on and gained power, then they added a BBK kit and they lost all the power that the bolt on's gave them, why is that, I think they said somthing about having a bigger diameter on the rotors and it took more power to turn the wheels but dont quote me. Can anyone explain this. FYI the dyno was the dynojet type.

 

I can see that happening. Makes sense as the larger 2 piece rotors that Endless uses weigh over 20 pounds a piece vs the 8-10 pound OEM rotors. So thats 20 pounds of savings but the Endless caliper are about the same weight as the Spoons. So its the weight savings. Remember every pound counts with these guys. They are so attention to detail oriented and they should be.
