Biggest brakes for 15inch rims??..

..thinking about this though.if you have the same wheel with the same spoke thickness etc and you move the hub mating surface further inside the wheel leaving the spoke face where it is,then surely you will get m0ore space between the inside spoke face and the hub??

Answers on a postcard please.
Thnks.

yes agreed, but my understanding is that when changing the offset then the spokes move with the mating surface so you dont get any benefit (apart from a deeper/shallower dish).

this is why spacers do the trick as they bring the effective mating surface further away from the inside of the spokes.. hope that makes sense (and that i'm not talking rubbish...)

On another 15" brake dilema topic. I have s2 calipers G60 Girlings, yes they're upside down but no I don't get uneven wear as everyone says. But I am getting disc issues I warped my vw standard disc slightly before going to The Nurburg Ring but when I was there it only took about 3 minutes to really warp them on the track. So on return I got some drilled zimmerman discs and I've only done about 2000 miles, no track time and they're warping now so as a last ditch attempt before I go stock I want to get drilled and slotted discs like blackdiamond, ebc, or Tarox. Tarox being about £190 BD £140 EBC £160 etc. Hopefully the tough metal and reduced contact will help, granted they will clog up over time but....

I'm thinking blackdiamond as I have had them before on my old mk2 8v and they aren't too expensive but if any of you think there is a better cheaper option I'd like to here your opinion as cash is elusive at the moment. They wore out quiet quickly on my mk2 but they were good.

Or could it be the pads that need looking at, currently running pagid pads, nothing special, £30 a pair.

Here's a link for what I'm looking at...

I don't want more braking efficiency from the new setup, although it would be nice, I want tougher discs and cooler running pads I think? So I can keep the S2 calipers without cooking my discs.

By the way they fit behind BBS RM's

EDIT: These are cheap!

Ok well I will either validate or disprove what your saying tonight as I am going to buy the and see.
It just that I am not going for a wheel with a deeper dish,it should be the same as the RZ's so...

i'll post up tomorrow.
I'll put the humble pie in the oven.

But while your there buying them I'd measure the bbs's you have that don't clear against the rz's, just measure the distance from the hub face to the inside of the spokes. You'll probably need two rulers, one to act as a straight edge against the face and the other to to the measuring. By how much don't the bbs's you have clear?

I would imagine you'd have an extra 5mm clearance if the design was the same between the two wheels.

edit actually thinking about it the rz's are 12.7mm wider but the offset is ET25 10mm less than ET35 so you may only have 2.7mm extra clearance if the the spoke and dish design are the same. I think!

I think dukest is right.
Look at this image of said wheels.
I compared them to a picture of yours and do seem to be slightly dished,explaining the extra wheel arch poke.
I may still buy them if they are in good condition.

Does he not have the centers for them? They could be quite expensive to get afterwards you know! The centers for them are different to the RM's

Ferodo FD2500 pads are the way to go Cooler running pad, that works even from cold, but get some heat into them, and by Christ they're good. Had some on my 256s and they were much better than Pagid fast roads on my 280s

then that is a show stopper.

Of course none of this helps VEEDUBBED,

Tanks for that Stu, so what discs? Anyone warped tarox discs or blackdiamond discs

I used the Brembo standard vented ones from GSF! They were perfectly fine.....and not ridiculously expensive

Thats interesting to know - I am running Pagid 421's and they are shocking when cold, which they are most of the time given my driving style.

i seem to be wearing through the 288 brembo discs from GSF that i put on the front of mine very quickly, they seem pretty soft given the wear thats showing after only about 3k miles on them.. thats with red stuff pads though - dont know if they are "too much" for the discs?

Tarox 40 groove crack under heavy use. I use vw discs with either Ferrodo DS2500 or Mintex 1144 pads, along with large brake ducts. They've stopped me many times from 170+ without warping!

I'll look into the ducting, any images?
