I was looking at reviews and comparisons of BBK kits to come up with the best bang for ur buck. I assumed it was all relative but it seems like stoptechs have the best designs when it come to performance. The wilwood also looked like they were the smallest size-wise but I DONT know if that will play into thier performance/stopping power............

But i wud like to know if anyone knows if the stoptechs is made for the cl-s.

fastbrakes willwood Part #: 13-SL4 ~ $1300
- 13" 2 Piece Slotted/dimpled rotors with Wilwood Superlite 4 Piston caliper

vs

StopTech Big Brake Kit (2 Piece Floating Directional design/4 Piston Caliper )

vs

ROTORA 2 Piece Front 330MM Disc w/ 4 Piston Caliper BBK ~ $1700

....... What are ur experiences with the following BBK sets ??????

 

I have got the ROTORA 2 Piece Front 330MM Disc w/ 4 Piston Caliper BBK, and have no complaints about them what so ever! I am still trying to convince myself that I need the rear BBK as well, but from what I hear, it does no justice.....but it surely would complete the look of the car! LOL

 

so you're just set on the 2-piece, or what?

I got the fastbrakes wilwood 12" 1-pc 4-pot cals and that stops good er en new. The cals are ultra light, they cant be more than 5lbs

 

How much clearance do those require for rims?

 

the same as all the other bbks, the wilwood clears anything with hi-disk... obviously...

but i'd like to try that stoptech kit....

 

BBK is one my planned mods for this year.

Wonder if I could get it before All-Cali...

 

Don't the Wilwoods require more space then the Rotora 1-piece BBK?

I just ordered some Legends and I spoke to Ron about BBK clearance. He said he made them to clear the Rotoras with MMs to spare. The Wilwoods I remember seeing required 2.1" from the face of the rotor to the spokes.

Once I get the wheels I will measure to be sure, but are the Wilwoods larger (requiring more spacing) than the Rotoras?

 

Out of all the mods i really think the my rotora bbk made the biggest difference from stock set up.

 

The 1-piece Rotora -vs- the 2-piece Rotora BBK requires different fitment due to the larger sized rotors. Rondy made the wheels I purchased, fit a Rotora 1-piece BBK, but when I got them in the mail, I found out that my 2-piece BBK needed a 5mm spacer, so I purchased H&R.

 

from what i heard yes, but all my rims that i've had, had a high-disk for bbk clearance and always had more than adequate room. more like 10mm extra.

i believe the wilwood caliper is slightly bigger than most bbk calipers (4 pot) but you will not have a problem if u order the right rims.

 

when you guys upgrade to BBK, don't you need to do both front and rear or else your stopping power is outta wack since you have more braking power in the front than the rear???

 

You don't need to get an all new setup for the rear, but I guess if you wanted you could get new pads and rotors for the rear. You do need to replace your brake fluid though.

 

For looks I would definitly replace front and rear but for mechanical purposes, Just changing the front and not the rear is logical.

 

the issue 4 most i believe its the $$$$$$

 

i want to believe the 2 piece is better protection against warping.

Does the fastbrakes wilwood come in 2 pc.
I was also wondeirng , is 12" not too small for the rotors ?????, I have seen some rotors dia as big as 14.1"

Is bigger not better ?? But if the 12" stops just as well as the 14" then I guess there will be no need for the extra weight........

 

It's not nessessarily the size of the rotor, but the amount of bite the caliper has on it. I believe our cars come with 11.2" rotors stock, can someone confirm? 14" rotors look nice, but does the caliper utilize the whole surface area?

Also regarding the rear BBK- if you were to upgrade the rear and have the same size brakes all around you would tend to have less nose dive. With larger brakes up front, you tend to nose dive, but manufacturers do that on purpose for handling reasons.

 

Oh okay so it isnt needed to upgrade BBK all around and anyways front would make more sense since its FWD, right?

Concerning nosedive, doesnt adding a nice strut/spring combo or coilover system remove nosedive entirely?

Do BBK come with SS brake lines?

 

lol, RWD use just as much braking up front as we do bro.

 

Yes But i dont think all of them come with the braided lines

 

I actually think civicdrivr is saying is that it is better to have the same size all around to reduce the nose dive of BBK upfrnt, if possible thus reducing NOSE dive.

I think 11.9" is abt right, so i guess u are saying that the bigger rotors (14.1") are just for looks becos the clamping force of the calipers is the real ishing factor

 

That's a good point.

So if I understand correctly...

After a certain point, larger rotors serve more of an aesthetic purpose rather than performance.

 

No. Thats not accurate.

 

Can you please clarify then.

 

first of all, if a rotor is just bigger than another and nothing else, NO there isn't any difference.

BUT usually larger rotors come with larger calipers (4 pot vs 6 pot) which has a larger surface for the brake pad. in this case, yes larger = better. IMO its the rotors made to accommodate the caliper, not the other way around.

 

Follow up question...

A 4 pot caliper with the same "bite" performs the same regardless of the rotor size.

Is that correct?

 

Thats basically what I was trying to say. You just worded it MUCH better.

 

There's a stoptech kit for our cars? How much does it cost and is anyone running it yet?

 

no actually bigger rotor does make a difference. imagine you stopped from 60-0 mph and you did this 100 times in a row. a 14" rotor would heat up less than a 12" rotor because there is simply more surface area for the heat.

but on the street it makes no difference. its almost impossible to heat up even 1 piece 13" rotors to anywhere near fading status. i have a rotora bbk and got it for looks mainly. even with aggressive driving theres no fade.

 

Regarding the caliper clearance. the 2 piece rotor for Rotora is way too big for the car even tho I looks great and is slightly lighter. Thing is, it requires a 5 mm spacer on even the most flat faced wheels. What this does is lowers the wheel offset to a point that would require fender rolling. So our 48mm offset (which is pushing the limit on a non-rolled fender and drop) would become a 43mm offset which is a bit too low. The one piece requires no fender rolling, no spacers and maintains the 48mm offset. The one piece rotor with 4 pot requires 1.25" of caliper clearance at the highest point. Factory CL brakes only require 0.25' of caliper clearance. From What I heard, the willwods and stoptechs reqire about the same if not more than the 2 piece rotora version. So the best bang for your buck BBK is the Rotora single piece rotor 4 piston front BBK.

As for the rear, I'm in the same boat as you Topher, I can't justify the small rear BBK, its barely noticeable.

 

This is a little off topic but do you guys know where to get drilled and slotted rotors for an 01 type s. I dont want to change the calipers because im rolling 16" stealies in the winter I found a set of fronts for $200 from raceshopper.com but have no idea what kind they are or if there any good and I need to change my warp rotors there driving me crazy.

any info on this would help alot thanks

they are quite a few just google...............

if u look in my sig u will see what i am running.....(frozen rotors in the frnts)

 

It really depends on the stock braking system. If you're going from an 11" single piston to a 14" 4 piston or 6 piston then you'll see a major improvement. The biggest improvement will be in brake fade. The BBK kits don't have as much or any brake fade compared to OEM units that aren't made by brembo or top brake manufactures.

Another thing to consider is, if you don't get a 4 wheel BBK kit is the brake bias. Some kits come with the brake bias valve already with the car specific kit so there isn't too much brake bias front or rear. So when replacing either just the front or all 4 sides the brakes are adjusted to have the correct bias applied. If you have questions you can call the BBK manufacturer.

 

I HAVE beign looking around at the willwoods also, so i will like to clarify this.
Are u saying there is NO way IN hell the willwoods will fit your wheels ( RJ inspyres or legends) without a 5 mm wheel spacer ???
pls clarify................

 

Just wondering if anyone knows what size KICS wheel spacer I would need for the 12.6 inch 4-piston Wilwood kit?
I have a 2003 CLS 6 speed on stock 17 inch rims.
Thanks!!

 

I will shed some light on this for you.....I have got the 2-piece Rotora 4-pot BBk. I purchased soem RJ Legends (19x8 + 48) and needed a 5mm spacer (if you do this...be sure to get a spacer that is hubcentric, NOT UNIVERSAL for ride quality/shaking & also be sure to use the extended studs for safety reasons). But with my 19x8 +48 volks....I did not need the spacers, but kept them on for flushness of my front rims. Alot of the fitment also has to do with the way the wheels spokes are shaped also. Any other questions that you have, just lemme know!

 

so im about to get a bbk, rotora or willwood?

 

^ Is cost a factor...?

 

you should try the legend upgrade with some slotted rotors and ss lines its the most cost effective brake upgrade this is the road im going to take

 

cost is not a factor. ive dropped 5 grand within the past 10 days on the car =]

 

I wish I was made of money
