As a 2 week old skyline owner it's all been a bit exciting so far...however...I can't help feeling that the brakes on the car are spongy. I've got a 1 year old r34 v spec UK and I thought it would be like hittting a brick wall when braking but, maybe not?

Any thoughts?

Thanks

1600 kgs dry

should see to that.
Big motor, lots of momentum and "only" 320 mm 4 pots.
Go for Ap 6 pots for huge power.
Maybe you have some air in them and need a bleed.

I'm in the same situation re the brakes.

I'm an 8 month old R34 veteran so I'm able to reach the pedals a little easier !! :D

I recently helped film an NZ performance car video and although I definitly wouldn't describe the brakes as spongy before that day, they could be better.

My question is which brand for calipers (AP suggested above, any others ???? Alcon etc) how many pots ?????? Not interested in having enormous brakes for the sake of it eg 10 pots etc

Then what about rotors ???????? Size, make, slotted ???? , cross drilled ??????

I had been thinking Alcon 6 pots front with 4 pots on rear, slotted and drilled rotors (not sure on brand) and then taking suggestiongs on Pad's although Ferodo seems popular.......not available in NZ will get some from UK.

Cheers

You really can't go wrong with AP racing 6 pots. There are various disc sizes and you should try and go for the biggest you can fit in your alloys. There is also the option of fully floating discs...but I really don't know how these compare to the normal ones. You really don't need to go for 4 pots in the rear as they don't do too much work. If you really want to improve the rears fit a bigger disc and better pads.
Not sure about the UK but Alcons seem to be slightly more expensive here. Brembo racing brakes are a definitive no no if you are on a budget...and Tar-Ox are pretty good but not built as well as the others. Project miu here in Japan makes pretty good kits too, and they use top quality alloys.

If you just want to improve the standard items(like I'm doing at the moment) fit braided hoses, master cylinder stopper and use decent pads....I'm going for DS 2500(cheers Mark!:) ). That will do me until I fit APs once the car leaves Japan. You should see the rediculous prices we get here....:rolleyes:

Thanks Dino, the main reason I wanted to do the rears too is so that it doesn't look dorky with 1 make on the front and another on the rear, and also huge rotors on the front and little fellas on the rear too..............gotta go for the look as well as the function............of course the functions more important.

Any of you guys in the UK got any idea of a full Alcon setup ? Front and rear, and rotors big as poss inside Blitz 18x10 ???
Ferodo Pads ????

Cheers

I have 6 pot APs on the front and love the difference it has made. If you want to go for bigger discs then go as big as possible but stick with the 6 pot APs as they're probably about the best.

Don't bother changing the back as the majority (70% I think) of the work is done on the front under standard braking and even more under heavy braking.

If you are thinking about bigger discs then you might want to think about bigger wheels as well - so you can go even Bigger!

Before I had my bigger wheels put on I used very hard pads on the standard discs. On the downside they made a lot of noise. On the upside they stopped the car very well. However, as they were so hard they eventually wore the discs out:( Which then meant new discs - 'ho hum better get new wheels';)

Bigger wheels aren't really an option on NZ roads !! 18x10's are big enough for my pocket too :)

Any lower profile and I'd be heading to the dentist more often !!

Looks like AP's are the way to go..........any idea on price from you guys ???? front, rear larger rotors that'll fit inside 18x10's ?

Cheers

How about fitting the factory 4 pot fronts to the rear? Does anybody know if this possible (with or without a little fabrication of a bracket or two)? I thought I once saw a GTR on the web that had this done. Not too sure where now.

Cya O!

Stop me! I'm fading fast.

I took my R33 GT-R to a Niismo specialist on Sunday I told him that ever since I’ve had the car the breaks have been a major weakness.

His remarks where basically that the original Brembos where good enough for the development cars at Nuerburgring and they had to do countless laps under extreme conditions.

However, they used Castrol SRF break fluid and Nismo break pads.

He personally recommends DS 2500 pads though.

I’m going to try Castrol SRF and DS 2500 pads at least. If this doesn’t work out then I’m going to try the advice of a friend that races Corvettes.

He uses the bigger Brembos (same type as found on a Porsche GT3) they have wider, thicker, drilled disks and bigger calipers and are about 25% cheaped than the AP’s.

My $.02 worth.

Big Brembo's

Hi Paul,

They're the same as these(Mov'it just rename Brembos) on a GT2.

These are the Brembos the Nismo Z-tune uses. Not sure the model name but they are 4 pots. They retail in the region of 700.000 yen here in Japan:eek:

Here are my Blitz Wheels............those Movit brakes look interesting.........

Keen to get an answer on moving the 4 pots to the rear too, then I can buy some Brembo 6 pot fronts........sweet solution.

Whats the story if I go to a bigger rotor ??????? is it just a mounting kit that needs to be made up ???

Canman...I remember Mark from abbey telling my that the front calipers won't fit in the back. I don't know why but I'll take his word for it. Usually bigger rotor kits come with the caliper mounts extensions....so no problems threre.

Does anyone have a picture of the Brembo 6 pots????
