Hey everyone.

I've been Researching about a Front brake upgrades/Kits for my R31 Skyline with 300rwkw, I have fitted S13 Hubs which allows me a lot more braking options. will be runing a 17inch wheel, no larger. Tyres get more expensive the larger the rim you go!

Car is used for club days (3-5 lap sessions) and will see the road once a week.

My budget is Between $2000 - $3000. I have made a list of some of my options, see bellow

1. Second Hand R33 GTR Brembo calipers, 324x30mm RDA or DBA 4000 series rotors, Ferodo DS2500 pads, ADR stainless lines and motul RBF600 Brake fluid $2000 or there abouts if your lucky ?

2. G4 Racing 330mm Brake kit (includes all needed parts) with Ferodo DS2500 pads $2250 Delivered

3. K Sport 330 brake kit (includes all needed parts) with Ferodo DS2500 pads $2400 Delivered

4. AP racing 4 piston caliper, Mounts, DBA 4000 series 324x30 Rotor (off the GTR), goodridge braided lines, ferodo DS2500 pads, Motul RBF600 brake fluid. $2650 Delivered

5. CSC brake kit. Between $2500-3000

Theres a list of what I've been thinking of, I'm almost sold on option number 4 but not 100% sure as yet.

Does anyone know if the G4/K sport calipers are fitted with Boot type dirt seals on the Caliper pistons ?

Feel free to voice your opions,

Thanks :D

option 2 for me (I think 3 is the same?)

I've bought 3 sets of g4s for different road and race cars, nothing else comes close for the price.

also option 1 is rubbish. I run them on my production race car because I have to, they are definately not worth the price

I'd go with option 4 and try and upgrade to the DBA 5000. Do you know what the kit is worth with the DBA 5000?.

However I have been told by a Sydney brake specialist that the newer DBA 4000 series are improved over the old series that created the bad reputation. I believe the slots do not go all the way to the edge of the rotor like the old ones did.

Thanks for the Replys,

At this stage it looks like I'll be going with option 4, But will be runing the CP 5200 4 piston caliper instead of the CP6600, which means runing a 330x28mm or 330x32mm DBA 5000 series rotor or similar. Should be able to manage this all for under $2950 Delivered

after doing a lot of research I've decided you really need to work out whats going to be the best set-up in regards to maintenance and long term build quality. AP have years of good reputation from there products being used in all forms of Motorsport. If this means spending a couple more hundred, its worth it in the long term!

G4/K sport kits are quite good for the price and i almost went that way but after seeing the two calipers side by side you really see were the quality is. also the prices for replacement pads and rotors are cheaper with the AP's.

R33 GTR brembos just seem to be way over priced for a second hand caliper!

Its really up to the individual in the end, and what you generally use your car for!

Thanks for everyones opions.

Cheers,

Andrew

Great.

What is the difference between the 5200 caliper and 6600 caliper? Edit: Just looked at the AP site and the 5200 has a smaller mounting centre and is lighter by 200grams but uses a slightly smaller pad.

I am picking up my AP kit this morning. Will post pics when I get it.

That would be good,

The CP5200 is generally a better caliper then the the CP6600. its stiffer in construction with the center bridge design like its big brother the CP5555 (6 Piston) The caliper is more suited for track work then the CP6600. Its also fitted with anti-pad knock back springs. I Have talk to a few people using this caliper and they prefer it over the (6 piston) CP7040.

The CP6600 has a similar look and design to factory fitted Nissan (4 piston) calipers and is more suited for Performance road applications.

How ever you look at it there both good, but ones better at some things then the other.

Also AP recommend there Black finish then the Red if your are considering doing Track work. Theres no point having nice shiny coloured calipers when it takes one drive down the road and there covered in Brake dust!

rbr31andrew: where are you getting your kit from?

I am unsure of the product number for that rotor size.

I just went out to measure the disc thickness and the thickness was 30mm. I tried measuring the diameter last night and I'm sure it was 330mm. I am unsure if DBA 5000 come in a 330mm x 30mm. When I spoke to V-Sport who make up the kit, they advised they often use a 324mm rotor. So I could have 324mm x 30mm size.

When I take the wheels off again will measure the rotor diameter to be certain. I am not fussed as it should make the rotor replacement cheaper as the sizes are more common.

The model numbers for the 324mm x 30mm are as linked; could not find anything abut 330mm x 30mm or 32mm. Could be easier to call them on +2 +9748 0211

Cheers.

Yep, sounds like its a common GTR 324x30mm DBA 5000 series rotor.

Which sounds right as this can be used with the CP6600! its quite good cause its a cheap sized rotor to replace!

The CP5200 have to fitted to a 330x28mm or 330x32mm. The GTR 324x30mm wont work.

Will hopefully have some more details tomorrow.

Yeah that's what I thought of; cheaper to replace. For the price I paid I am certainly not going to complain!

Whilst I liked the idea of having a 330mm rotor the extra 6mm would be hard to notice out on the track I would imagine.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel

      What should I do next to hold the head on

      By MBS206 · Posted

      When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?

      Chris' Toyota Mark ii JZX110

      By Rezz · Posted

      Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.

      If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
