BNR34 Brembo and BIOT Brake Upgrade (Front & Rear)

If you have followed this blog for sometime, you would have recalled that I fitted in a set of Endless 6 pot brakes on the ER34 for a wee bit of time before it was removed (Read here and here). The issue was due to the minute clearance between the calipers and the inner wheel. Too small of a margin for me to feel comfortable with. Better be safe and paranoid than sorry later on eh? There were just two options for me then, switch to a new wheel with bigger clearance (i.e. TE37s) or remove the brakes.

I choose the latter and had since sold the set of Endless 6 pots. It now resides in a cool looking S15 Silvia. :(

Fast forward a year later, I'm now dabbling with brakes again. Via JDM Auto Link, I have managed to get a set of pretty rare BIOT Front Brake Offset Kit. This kit consist of a set of rotors and brake brackets to complement the BNR34 Brembo calipers.

The BIOT Brake Offset Kit is not an affordable kit either. Just the front rotors and brackets alone cost upwards of JPY 160,000. Yeap, BIOT parts is not your run-of-the-mill items, they are at the top of the ladder in terms of performance and quality.

For the rear, I'll slot in the stock R34 GT-R Brembo brakes. That would do unless JDM Auto Link can source me a set of a BIOT Rear Brake Offset Kit that would bring the rotors up to 322mm. :P 

The set of brakes that I procured consist of:-
1) BNR34 Front Brembo Calipers
2) BIOT 345mm Floating Rotors
3) BIOT Front Offset Kit Brackets
4) BNR34 Rear Brembo Calipers 
5) BNR34 Rear 300mm Rotors

The set of BIOT brakes enables the ER34 to move up from its stock 310mm brake rotors to 345mm rotors. That's a nice upgrade in term of size. How does that improve braking?

A bigger rotor has more material in it so it can absorb more heat. More material also means a larger surface area for the pads to generate friction with, and better heat dissipation. Larger rotors also put the point of contact with the pads further away from the axle of rotation. This provides a larger mechanical advantage to resist the turning of the rotor itself. To best illustrate how this works, imagine a spinning steel disc on an axle in front of you. If you clamped your thumbs either side of the disc close to the middle, your thumbs would heat up very quickly and you'd need to push pretty hard to generate the friction required to slow the disc down. Now imagine doing the same thing but clamping your thumbs together close to the outer rim of the disc. The disc will stop spinning much more quickly and your thumbs won't get as hot. That, in a nutshell explains the whole principle behind why bigger rotors = better stopping power.

Put quite simply, bigger rotors give you more surface cooling area, so they will stay cooler.

I just got it installed and is mighty pleased that the brakes fit in the wheels nicely. The clearance between the edge of the caliper and the inner wheel is just perfect. The front brakes fill up the wheel orifice nicely. I'm pretty happy with the outcome. 

Oh btw, it's not a direct fit per se. The BIOT Offset Brake kit will require some grinding and shaving of the Brembo calipers and also the knuckle. Nothing too major but just make sure it's done properly. Picture 9 shows a part of the knuckle that have to grind off.

I'll post up some proper pics of the brakes on the car on my next update. Will get some good shots done up and share with you guys.

Carbon Fibre Rear View Mirror Cover

Just got some bling for the ER34. Via JDM Auto Link, in came a nice carbon fibre rear view mirror cover for the ride. Basically, it's a snap on cover on the existing rear view mirror. So instead of showing it's beige colour via the front windscreen, it now is displayed proudly in carbon fibre.

Small little thing but I think it should look better when photos are taken from the front of the ER34.

107,000km Service & New Silicone Hoses

Pic 1: Fresh oils into the ER34

The ER34 has just undergone it's 107,000km service. Fresh fluids in the form of Torco SR1 10W-40 went in together with an original Nissan oil filter (Part No. 15208-53J00).

At the same time, did a small little bit of sprucing up the engine bay. Covered up the holes on the firewall where the heater lines goes to with nice silicone caps. These are no longer in use as the heater lines have all been removed during my stage II upgrades. At the same time, also covered up the unused hole where the original fuel regulator used to be.

Small touches but good enough to somewhat tidy up the engine bay a wee bit. :)

Nissan Skyline Mega Gathering in Malaysia 2011

Pic 1: The cars at the gathering

Recently, the Nissan Skyline owners in Malaysia had an gathering at the federal administrative centre of the country, Putrajaya. Basically, it's a meet up session to mingle around snap some photos before heading out to the nearest food stall for a bit of chowder and more chit chat. 

I reckon there were close to 40 Skylines comprising of R32, R33 and R34 Skylines plus a lone V35 Skyline. Most of the lot were ER34 and BNR34s though. It would have been excellent if there were older Skylines present like the R31s around.

Took some pictures and a video. Do check them out below.
