brembos = huge overkill and waste for the street. get some GT Liberty 316mm fronts and 290mm rears. 1/4 of the cost of brembos.

MY07 GT spec B

not possible.



sif brembos are overkill. you pansies aren't going fast enough, or braking hard enough!

Nothing like charging 20psi and braking all the way up AND down a mountain pass, and not worrying about cooking the brakes :dance:

I'll have 08' GT spec B 316mm front brakes with brand new oem pads, s/h rotors (never machined, heaps on them) and brakes will be paint gloss black, pins regreased for sale in 1 week.

Awesome upgrade for a Gen1/2/3.

Seeing as this thread popped back up i best post something of use...

be Careful of clearance on the 16in Wheels with B4 calipers! there is literally only 6-8mm clearance.. i only found out there was an issue when i swapped wheels and found the weights that were stuck on the inside of the wheel to balance were all worn away and my calipers had nice score marks on them haha

not really sure, its still getting a shitload more torque down to the wheels because of the extra diameter which should be plenty of an upgrade. someone was selling a set on ozlib for 900 a while ago, ask them what they think about it if you can find the forsale advert



I often see this type of comment about brake torque. The truth is that if your standard brakes can lock the wheel (ignoring ABS for now) they generate as much brake torque as you can use. The reason for upgrading the rotor size, both diameter and thickness is to provide better short term heat absorption (while the brakes are applied) and longer term (period between brake applications) ability to dissipate the thermal energy to the air. This helps to avoid brake fade. The other misconception about brakes is the reason for multi pot calipers. OK, yes they have bling, but the real reason is that larger pad surface areas help with distributing the thermal energy of braking more evenly into the rotor. Larger pads tend to bend in the middle on a single pot caliper so the pressure application is not even across the pad, defeating the purpose of the larger pad. Multi pot calipers should apply even pressure to all parts of the pad to achieve even heat generation and avoid hot spots. They should also look damn sexy!! :)
Because stopping never optional.

I may consider doing this upgrade in the future, after my suspension.

I tried to pull up from 100 last night to slow down for a bump in the road, the brakes were awefull. (the ones in my last two cars were so much better, would pull me up in half the time)

I think my rotors are warped anyway so might do it all at once.
