This is one of those threads were I really should just tow the line...

The caliper kit on the stock R56 (R53 JCW) will be a lateral move for the most part. While that seems counter intuitive keep in mind that not everyone's needs are the same. For some a nice (and very sexy) caliper change can be a very nice enhancement to their car.

Any opposed caliper will offer you improved feel and response. It's design based not how many pistons or color. (!) The future use of current JCW (R56) rotors of greater diameter will only go to make this better in due time. Currently these rotors are too costly to make it a viable plan. However for those who have older ones in the garage or crave ebay specials of the current rotor this package makes a great plan and truly an affordable one for what you get. (see vendor section above)

In time I'm sure we'll find more pads beyond the BP10 and 20 to pick from and maybe even some two piece 12.5" rotors will come to market....you never know. But if hard core, ***** out, track use is your thing this is clearly not your product- you need more rotor not more pistons.

Still this is more than adequate for street, autoX and occasional light track use. While I won't 'oversell' it I won't 'undersell' it either. One major plus is that it clear stock wheels! Let me repeat that: IT CLEARS STOCK WHEELS! If you oem iron caliper clears so too does the DP6. Nuf said on that.

As for stopping from 60-0 in 30ft. I could happen. You just won't like the result.

 

Sounds like a nice additional benefit. Would that be 10 pounds per side?

BTW, this thread has been a lot more entertaining that I anticipated....

 

I suppose that's how it normally is on NAM... sigh

 

I didn't think those calipers were THAT much lighter are they?

 

I'll tell you tomorrow. That may be a bit optimistic but given the added size it may not be all that far off.

 

Because someone asked:

Loaded (pads included) the DP6 weighs in at 5lbs 8.2oz.

And I must say this is one damn nice looking caliper too. I'm about - close to pulling the trigger and adding it as an option on the 13" kits. Anyone want one? Push me over the top.

 

That's very impressive. How much would the 13" kits cost with this caliper? While we're talking 13" kits, do you have any pictures of the kits with the new, larger hats?

 

Hats; you know, I don't believe I do yet. There are about five kits in service that I can figure so I'd guess there are a couple shots out there somewhere. One inch larger OD and 12 bolt not 8 is the difference. It was about a 50/50 form/functional change.

The difference in cost of the DP6 over an FSL kit I'd call that: $250. All in all $25 less than my other FSL to BSL6 subs in other kits. A slightly less costly caliper and pad combo here. Puts you well into the $1500s this way.

 

ok, im bringing this on back from the dead.

after a caliper seizing on the track the other day, i need some new brakes.

I like the idea of JCW, but i plan on tracking alot more next year, but by no means a track rat, but figure that this would be a better way to go, despite my love of the JCW emblem, hahah.

I actually have a R50, but since this DP6 kit, replaces the JCW bits, im thinking of buying this kit, along with JCW rotors. Is there any factors im missing on installation? I assume not, since it says JCW in the fitment bit on TCE website, so i think it should bolt right in.

Also, say in 2 years, i want a true BBK, What options will be available to me while retaining this caliper. I assume it wouldnt be too big of a deal to set up to the 13 inch kit with just mounts rotors and hats? What about custom 12.2 or 11.75 set ups using this caliper?

and i didnt see the actual weight of the loaded JCW caliper show up, anyone have that info handy?



thanks guys

other than the grinding, it will bolt right in i mean, hahah

and actually, what about 15 inch rims? The rims im getting (15x7.5 949s) work with the JCW, so that should mean these work as well right?

I have brackets now for both the 294mm (which need the grinding to clear the ears of the caliper) and for the new 316mm disc (which I don't believe will require that grinding- or at least verrry little) so you can run either size or start small and then go larger with a set of the bigger brackets later.

You are partially correct. The DP6 will in now way interchange with the normal DP found on the 11.75 or 12.2 kits. (besides the 316mm is already bigger than both) but you could move to the full 13s (.810ish width) and the two piece hats. That added cost later would run you about $650 with the brackets, hardware and all.

 

is there anyway of using either the 11.75 or 12.2 2 piece rotor later on? the existing JCW rotors are 11.57 and 12.44 repectfully anyway, so that shouldnt be an issue. is it just a backspacing issue on the 2 piece rotors that wont allow it to work.

the only reason i might want to go to two piece rotors is for weight savings. how much weight is there to save by going to a two peice 11.75 over the current 11.57 JCW rotor? or are we no talking enough weight for it to matter. For some reason i am just really drawn to the 6 piston caliper, but want to be able to run 15s or at least 16s for now. I dont know what it is with me and the 6 pistons, i just like the way they look, and how big they are. Total overkill, but thats not the point, hahahaha. or would the extra mass of the all iron rotor be and advantage in heat soak and duty cycle anyway?

Horsepower, i know, suspension, meh, sort of, brakes, yeah, no, not so much.

thanks for all the help

actually, never mind, thinking of it. if im going to the 12.2 inch kit or the new JCW rotor, i will be running 17s anyway, so i might as well go to the 13 inch kit anyway. yeah.

but im still wondering now, how does the loss of mass in the alloy hat factor in to heat retention, and duty cycle, and would love to know weight differences, just for reference. Im pretty sure it the DP6 on JCW rotors im going to be going with anyway tho. and eventually, probalby the R56 S rear 10.5 brake to go with it.

thanks so much

Beecher

ps, how far off are the poly A or B pads for the dp6? and price? I will probably get some of them for the track season as well. I see they are coming soon, but nothing on your site yet.

If you were to change from the JCW rotors I can't figure why you'd want to move to the smaller two piece rotors anyhow....I suppose it could be done but you'd be on the hook for custom brackets. Currently it's JCW 1 or JCW 2 or the 13" rotor. Can't see much need for another one.

The aluminum hats with their air channels will be more efficient than the one piece iron part. The all iron hat/rotor will retain heat (iron does that) whereas the aluminum hat dissipates heat better.

Wish I could give you a firm date. I was told mid Sept. But that didn't happen...I have them on order so when I know, you'll know too.

 

OK!! thanks a lot. I like to overcomplicate things (hence the halfa$$ custom bbk, instead of the 11.75 anyway). Im not in a rush on the other pads, no more track days for me this year anyway, I just wanted to make sure they are still going to be available (ive had stuff on order for 3 years before i got it all, and ive had on manifold on order for 9 months already, with none in sight yet, keep hearing in a week or 2 tho, hahaha).

anyway, thanks again for all your help.

will be ordering them when i get back home from a business trip to houston this week! (im getting tired of smelling burning brake pad...)

thanks again

I'd suggest you see what you can dig up on the later JCW rotors. The 316mm parts. Having this will make the install easier and improve the overall product. I'm not sure who has them yet here in the US that's the problem....

 

yeah, but i want to run 15s. hahaha. call me crazy.

another question. Im thinking about getting the red powder coat. how does that stand up on the track. I know the black really doesnt at all, does the PC work good, or does it get hot, and melt off or some thing?

also, what pistons are in it? the dust booted ones, or the stainless steel?


thanks

 

Mounted to 314mm discs there's no way this will fit a 15" wheel. The rotor is slightly larger than the Plus 2 kit rotor so 16s will be in order. The deal however is that despite the tall slender nature of the caliper it doesn't take up more room than the stock caliper with regard to body overhang. Making it very wheel friendly.

Red will hold up ok. The base color is black and also pc. Red will show the dust a bit more...

All DP6 calipers run stainless steel pistons for heat rejection.

 

hmmm, if I can run the new JCW rotor on 16s, then maybe some research is in order.

I figured i would have to go to 17s, and seeing my car with 15s, parked next to a car with 17s, i liked the 15s better (plus they are better on the track anyway, so ive been told), ive always like the looks of 16s the best, but there is limited rubber and rims available in 16s (complicated by the habbit of running r comps on the street). If only 949 racing would make the 6 ul in a 16. those are the rims i want to buy.

i was going to call you tomorrow (before the cdn dollar gets any worse...) but now i must do some more digging)

thanks again

Beecher

 

random question but do the wilwood calipers come in white?

 

Only if I custom pc them.
