have always liked the look of 33gtr rims. if they fit over my front brakes i'd likely have a set. what's the aspect ratio of those tyres - they look a bit tall... edit - 245/45/17 sounds about right...

fark gareth you're a hard man lol!!

ballpark is about right

forget it, sarcasm has been lost on me... lol

blk180 - wanted to say - HOT RIMS

yep i reckon. have a look at www.gtr.co.uk, under the wheels, brakes, tyres section of the forum, and check out the "pics of wheels on cars" thread. there's a lot of rim/tyre combos there edited - link should work now

probably a bit narrow unless you like the stretched look- try 265/35/18 or a 275 if you really want to.

surely whiteline or superpro can supply a larger bracket? best give a suspension shop a call

Agreed. i had a light switch ORC twin in my GTR32 and swapped it for the Nismo Twin. All this talk of "big men" with "hardening up" and "get used to it" A properly engineered product can take 1000hp and feel stock. Why would you make something difficult to drive if it doesn't have to be? to be a "man"? lol fark you guys are funny.

keep it. 32s are the best

i'll put up the piston sizes when i get to work... GTR32 (Sumitomo) Front Caliper Piston (diam x qty) - 40.4 × 4 area total caliper sq. cm - 51.28 Rear Caliper Piston(diam x qty) - 38.18 × 2 area total caliper sq. cm - 22.90 GTR33/34 (Brembo) Front Caliper Piston(diam x qty) - (44+38) × 2 area total caliper sq. cm - 53.09 Rear Caliper Piston(diam x qty) - 40 × 2 area total caliper sq. cm - 25.13 Total volume front and rear (by one side only) sq. cm GTR32 (Sumitomo) 74.17 GTR33/34 (Brembo) 78.23 % diff from GTR32 sumitomo to GTR33/34 brembo Front 103.5% Rear 109.8% now my hydraulics brain is not working so well, but if F = P x A, then the brembos have a slightly greater rear bias. so if you upgrade the front calipers only, you'll get a slightly greater increase in front bias. Note that this will increase even more because you're using a 324 rotor instead of a 297 rotor... In answer to your question, the spaced R32 sumitomo caliper will work fine with the larger rotor, the swept area won't be outside it's working capacity. The brackets in the picture are the offset 'spacers' or dogbones as they're sometimes referred to. The 2mm narrower thickness rotor won't be a problem either - it will have the same effect as having ~1mm worn off each pad. cheers

i think you should be ok with Roy's calipers as the GTR offset and wheel design gives better 'face' clearance... i think his issue relates to the shallower offset of GTSt rims - basically how close the wheel is to the caliper. There are heaps of people doing GTR brembo fronts with std sumitomo rear calipers - they should come up ok balance wise. They are a slightly bigger piston area, but it's fark all (don't have my specs on my home computer). Would be better if you get the rears too but they tend to go for around 500-600 bucks calipers alone... front Brembo calipers I reckon should be around 1K mark, but really for an OK (not excellent) caliper should come with good life OEM rotors for that money. My opinion won't stop people advertising GTR brembos for 1400 with rotors though even though they're just an ok caliper. if you want to, you could first try rebuilding your calipers (really little difference between them and the GTR brembos) with new seals, getting a caliper offset kit from nismo.com.au make sure the brake lines are in good nick (if not throw on some newies, or braided if you want), good fluid. this will be 95% of the way to the R33 brembos and you know that then you have basically a new brake setup - second hand brembos may require new seals etc etc so the exercise may be $$ if you're not happy with the 'basic' upgrade, sell the set to someone on nissansilvia.com, and save up for some proper big calipers like Roy's F50s or Alcons, or AP CP5555s. i just don't think the GTR brembo is such a 'good value' 'upgrade' for the money people are asking - for $800 including rotors, it's a good deal for a marginally bigger caliper and rotor, but for $1400 I reckon they're not worth it. my 2c - hopefully someone who knows something might chime in...

stealth black oh yeah

ok, i bought it for $5. i did a lot of things that I'm very ashamed of, but it was worth it...

hi dane rotors were hideously expensive - 355x36 AP rotors. If we went with 32-34mm rotors this would have been the old V8 supercar size which was cheap as chips (relatively) Pads are actually standard CP5555 size DS2500s - I would prefer to swap for a set of Endless CCX if they come in that size though - I find the DS2500 provides pretty ordinary feedback comparatively. the caliper is spaced with a plate from AP - though I believe that RaceBrakes can do this here. cheers

just adding to djr's post - try and stay away from the drilled rotors - they are more likely to crack and fail. Some of the OE rotors that are drilled are cast that way - which will reduce the grain issues and likelihood of stress concentrations where a cast rotor is later drilled. also, while having more vanes may make the rotor heavier, remember that all you're doing with brakes is converting kinetic energy to heat energy. The larger the rotor (ie more mass to it), the more heat capacity it has before fade sets in. Secondly, the faster you can get the heat out of the rotor into the surrounding air, the longer the brakes stay good. this is why you see the complex brake ducting to the the rotors on race cars - all about getting the most heat out of the max size rotors allowed for the class of racing. as an example, the calipers I have are an enduro-type caliper, that takes a 36mm rotor. They are super heavy (even with an alloy bell/hat) but should allow heaps of heat capacity.

it's a fair price, there's just too many gutter scrounging tight arses trying to low ball people.

I agree with Roy on grabbing some Endless CCX pads - the ones he's using were in my car before I upgraded. Note tht if you go to R33 Brembos (note all R33s have the same brakes, not just v-spec has brembos) you'll probably need to go to a 17" unless it's a big 16 like TEs or alike.

oops.

hey gareth you want to separate the front brake ducts? I have a rear bar but the tabs are farked. also may have tail lights... give me a buzz

i recommend many hours of reading in this section of the forums. you'll find out quickly which are your key knowledge members.

doesn't AP own Brembo or the other way around?

fark. what's the labour on the box?

stock will do n1s just fine
