Dennis, The calipers and rotors are new and coming from a Brembo reseller in the UK. The bells and brackets are special engineering. The total price of the modification is in excess of 17.500 US dollars for the 4 wheels. Maybe a bit expensive but the result is impressive! I keep my stock wheels and calipers if I have to revert to original mounting. If you want more details, send me an e-mail, I will be glad to give you full details. Phil. | ||

Phil, the Challenge brakes look great. Where did you get them (new or off a Challenge car)? How much, if I may so inquire? How long to retrofit? Did you sell your stock brakes? thx, --Dennis | ||

I put F355 challenge brakes on my 92 348ts. It brakes like hell. Enjoy the pics. Phil.   | ||

Yeah, but the ENZO rotors have holes in them, so some of the folks here wouldn't be interested anyway. Rob considers them a possible "performance disadvantage"! Of course, maybe it makes a difference with carbon rotors rather than steel. | ||

You can always retrofit the brake rotors and calipers from the Enzo for $35k or so. | ||

Thanks for all the info guys. I don't intend on tracking the car, so the upgrade is more of a cosmetic thing for me rather than performance related (although I would expect some improvement over stock). I am getting ready to have the existing calipers sprayed red and thought that I would replace the calipers while I have it torn apart. I am still really partial to the two-piece cross drilled design and will call some of the companies you all recommended in the morning to see what they have to offer. | ||

I went with the slot 2-piece brembos, I think they look pretty cool too.  | ||

It's also a cooling issue... I have brembo drilled rotors all the way around on my 308QV, no more brake fade on track days since I put them on! | ||

Mike, drilled rotors are a marketing decision, no longer a performance advantage. They can actually be a performance disadvantage. But they look fast...  | ||

Mike, If I understand what I've read, the slight increase in performance that cross-drilled may give you does not offset the cost + increased chances of cracked rotors, etc. Ultimately, the best way to improve braking performance is to get better rubber. If you can lock your brakes using your current set up, bigger/cross drilled rotors won't let you stop faster. The limiting factor will be how good of a grip you have on your tires. Dom | ||

Mitch stated: Hmm, I guess Ferrari didn't have performance in mind when they put drilled rotors on the F50, 550, 575M, 360, or the ENZO, but merely cosmetics? I don't think so! | ||

If you're interested in cross drilled rotors, and have some time on your hands, check out this thread: http://corner-carvers.com/altimathread.php.html | ||

I have to agree with Dave and Rob. The issue with a drilled rotor (or even a rotor where the holes are cast with the rest of the rotor--Porsche) is that the hole allows air to coole the inner edge of the hole faster than the rest of the disk. Therefore, the drilled holes are a stress riser and cracks start there. In the distant past (like 20 years ago) drilled rotors allowed gas to be expelled; modern pads do not generate this kind of gas anymore. Drilled holes are pure cosmetic. If you really want to use a pad that outgasses at high temperature, you will be much more satisfied with slotted rotors--as these do not have the same kind of stresses in hard use that the cross drilled rotors have. | ||

Cross drilled rotors on road cars is a marketing plus. Many enthusiasts like the 'look'. That's why they're availalbe for almost all cars. There are plenty of threads on this subject of drilled vs. slotted. Christopher, unless you want a custom rotor, which may or may not be that expensive, go for the OEM size drilled available. If you're tracking the car, don't use the drilled rotor. Custom? Call Brembo direct in California, then StopTech, then Fastbrakes, then Stainless Steel Brakes on the East Coast, then Willwood for a referal, then Stillen, then Coleman in Michigan. It also may be possible to fit the OE 360 disc to a 348, though it's one piece, it is larger. This is actually a very popular disc in the industry in general. Any manufacturer claiming 'Brembo brakes' on their car is most likely utilizing the same rotor as on the 360. The advantage is cost. | ||

I did not think the 348 had a spare wheel. I have got Tarox bakee dics on my 348 Spider. Actually work better then the Brembo.. | ||

Why cross drilled? Solid rotors are not only cheaper to replace --even on the 2 piece/floating setup-- but work better. And, I agree w/ David, AAA membership is worth its weight in gold, and so is fixaflat. | ||

Ditch the spare and get a can of "fix a flat" and a AAA membership. That solves that issue. :-) | ||

I looked through the archives for over an hour and didn't find anything that specifically answered my question. I want to upgrade the rotors on my 348 to a cross drilled configuration. Although I currently have 18" wheels on the car, my spare is a stock 17" rim. Because of that, I can't use the Brembo Gran Turismo "big brake kit" (which requires 18" rims to clear the calipers). I know that Brembo offers a one-piece cross drilled rotor that will work with my factory calipers, however I REALLY like the look of the two-piece rotors. I guess my question is, does Brembo (or another reputable company) make a two-piece rotor that will work with my existing calipers? Thanks in advance for the help. |
