Is it Endless that do the Greenstuff? I had greenstuff in the front of my supra, and they were EBC. or have things changed. Why black stuff in the rear? Aren't they the higher end ones, ie need a lot more heat to work?

I've read most of the posts, but after 20 something pages it got a bit hard to focus and I think I skipped bits..my bad...

I'm going to end up pulling the brakes out and tracing them...I can see it coming.

i knew there was an E in there somewhere.. go to autobarn and ask for bendix as they will have the guide, i've looked in it and they have outlines of the pads, they have a listing for the fj powered cars! i'm running bendix comp-X pads...

they have a listing for fj's?! w00t! I coudn't get decent bendix's for the supra. Stupid bendix. I put in standard bendix pads..and took them back out that same afternoon and turfed them.

That still doesn't tell me why to run blacks in the rear! haha

The number I gave is for fronts, they seem ok, not chewing out the rotors as fast as the metallic pads that were in there before

alright thanks, I've got the spare parts guy looking into it, hopefully he can come up with something! and hopefully he can find a listing for the back cause they are really stuffed!

While on the topic of brakes again just wondering if anyone has looked into a brake upgrade for the rear, I have the fronts sorted but to do the rear as well would be nice but not necesarry, either that or I need to buy new rotors which arent cheap at all, so I would like to spend the money going bigger as bigger is better in my books.

Anyone?????

Im only guessing but what about bolting the standard fronts to the rear? (disc and caliper) if they ARE the same that would be stage one as you now have vented rears. stage two would then be honda accord calipers and hilux calipers

I have heard this is a straight bolt on for the front and are 4 mm larger in diam as well as 4pot calipers.

you would also probably need a brake bias valve for stage two because your front rear bias would be all fuct up. But like i said, im only guessing. hope this is of some help....

Project Skylux Update....engine and box is sitting in place. firewall chopped back 150mm. And ive made the sump and center oil pickup...its getting there ! (slowly)

I havn't checked but I'd be a little surprised if they were the same diameter, feel free to prove me wrong though. I can't see hilux discs going on with being redrilled and whatnot as they're a 6 stud (on the 4wd's). Why the honda accord calipers? The backs are going to be a bitch because of the handbrake on the caliper IMHO.

What about r32/33 skyline or sylvia discs? they're 4 stud, I have no idea how close to fitting they'd go though. or get a set of good discs/pads/fluid for the current set up. Cause I find the standard ones, even in the absolutely stuffed condition mine are, aren't too bad. Put on a good set of braided hoses and I reckon they should crank. Or stop you from cranking even.

BRAKES!!!!

They would depend a lot on the use of the vehicle.

My HR30 PNV has over 250rwkw (about 340rwhp) more than most of us on this thread will ever have.

I have BNR32 GTR fronts (296 x 32 ventilated rotors) with Nissan 4 spot alloy callipers, the rears are standard DR30 2000RS (290 x 10 solid rotors) with standard single spot calliper.

Bearing in mind that a large proportion of the braking is done by the fronts, using slotted rotors and EBC, Endless or similar pad upgrade, you should find the braking more than adequate for all but the most extreme race conditions. S/S braided lines will also help, as they eliminate the expansion the rubber lines get under application pressures. Makes the pedal feel harder.

Z32 300ZX (280 x 30 ventilated rotors) are also an option, but in both cases, the offset of the front wheels has to change to alloy clearance on the 4 spot calliper.

My car is going to engineering with stock DR30 all round and after fronts will be modified to suit BNR32 GTR, because wheel spacers OF ANY KIND are illegal and very necessary to cater for the 4 spot calliper.

I am planning to use my car for Super Sprints & Hillclimbs and they will be the best I can get, for value.

Someone please tell me why I need bigger, but first go to the Jenesis site www.r30.co.jp and tell me where they say anything bigger than DR30 rears are required, and they have been racing these cars since long before we all got interested in them.

My bad...typo...i meant hilux calipers. what ive heard is they are a bolt on for the front.

Why the honda accord calipers?
I meant Accord discs.......maybe it was prelude tho......i dont remember..

but like I said...im guessing , because i dont remember for sure......maybe i jogged someone's memory who DOES know :D

I just looked at an old issue of HPI where they bolted R33 GTS25t brakes on to a CA18 Silvia. The 4 pot callipers bolted straight on to the Silvia calliper mounts, and they just used rotors that were 275mm vented, 4*114.3 (cant remember the thickness though, but reasonably thick) that JMS sourced.

Are our calliper mounts the same as S13? If they are then this seems to be a reasonably good way to go

You all got me f#@ked!

Why keep f#@king around with 275, when our stock fronts are 274, 4 spot callipers I can understand, but no advantage in 1mm.

As far as I know, all Nissan S13/14/15 & Skyline DR imports have 100mm mount centres.

Bet the JMS conversion was Z32 (280 x 30) set up, as it's a very common upgrade in Silvia circles, just re drill the rotor to suit 4 x 114.3, instead of 5 x 114.3.

The big problem is hub offset, but maybe I should investigate this eh! maybe S13 ABS hubs might be same as HR31 ABS hubs. If HR31 ABS type hubs can be located, I'm led to believe the Z32 conversion is a simple BOLT ON affair.

No! there to close together for the later calipars you'd need to get custom calipar mounts made, thats the problem the front struts wont let you bolt on any decent calipers and the rotors incorparate the hubs so you have to fabracate something to upgrade an all...

r33 in the N/A version have the 4x114.3 stud pattern so there rotors and calipars should slip and bolt on to the silvia fronts??

with the hr31 stuff your talking changing struts too.. to make it a bolt on thing?

here pics of what we need??

The JMS upgrade for the Silvia in HPI used GTSt Type m 4 pots with new 4*114.3 rotors (not redrilled 5 studs) they might have been NA rotors, not sure.

So basically we need different struts?

You just need wheels that instead of having dish have the hub recessed in the centre with the spokes on the outside

Are'nt all HR31 hubs the same? I thouhgt the "ring gear" bit for the ABS was just added to the inside of the hub,with no offset change....

As we know the HR31 struts have 100mm mounts,so type M or Z32 4-pots would fit,but are you also saying the bigger type-M/Z32 rotors have the same bearing as the HR31's??
