BIG Brakes on a small budget - Page 2

If people are wondering how much brake you need when pushing it to the limit on the track...

My brother runs 1000kg Harrison - 320+rwhp
Front: 300x32mm DBA4000 slotted Kangaroo Paw vented rotors. Skyline R32 GTR 4 piston calipers with Race Brakes pads. (Closest compound you can get to full race and still be able to pull up cold on the street(0 degrees)
Rear: 300x18mm DBA4000 slotted Kangaroo Paw vented rotors. Skyline R32 GTR 2 piston calipers with same compund Race Brakes Pads as front.

Front rotors have ducted air from front brake intakes.
Using Castrol GP600 fluid.

This set up is not enough...Woody brake pedal if it is pushed too hard.

Looking at better air ducting from front nose area where there is postive pressure. And maybe moving to full race pads and swapping in street pads for road use.

As most Cobra's are heavier than this one and some here are producing more power...If you want to go 100% on the track will need good brakes.

Hi there Mike, long time away for me!!!! Has anyone fitted a big after market brake kit under 15inch wheels? Will be running outboards on jag rear and running jag front. Budget not really the issue, just finding something big that fits is the issue. I want to keep the original look of the 15inch pin drives, thats why i haven't moved to 17inch rims.

Andy.

You will be limited to whatever you can get to fit inside the rim.

Lots of information on brake combo's that fit inside 15" wheels on http://www.gt40s.com Best way to search it, is to use Google advanced search and put in the settings to only search gt40s website address.

It's actually quite surprising what they get to fit.

I had to go to 18" wheels to fit my brakes.

Thanks Craig, I will give the GT 40 forum a shot and see what I can find. There must be something that will work.

Nice to see you back on the forum Andy

If budget isn't a problem Hi-Spec have some nice kits for disc sizes that will fit inside 15" rims. I think they even have a 6 piston caliper that will fit. They used to list a Jaguar kit but they have taken it off their web page.

It might be worth droping them an email and asking what they can supply. Here's a link to their web page.

Hi-Spec

Cheers

Thanks Mike, waiting for a email reply from them now. Talk soon,

Andy.

Mike: look great those new hubs! Out of interest, did you consider machining the whole lot out of one piece and dispensing with the pin drive adapters?

Aussie Mike · #29 (**permalink**) 05-27-2006, 07:40 AM

Yes I did consider doing the whole pin drive hub in one piece. The thing that put me off was how difficult the wheel bearings would be to service. It would also mean I'd have to consider a different style of disc rotor. The HSV rotors are available everywhere and are reasonably cheap. I paid $160 each for mine.

I also like the idea of being able to swap to a bolt on wheel if the need arises. i.e. a second set of cheaper steel wheels with race rubber. Or a spare wheel with dual bolt patterns to suit front and rear.

Cheers

Thanks Mike, I hadn't thought about the wheel bearing access but yes, that would be really awkward. Do you know offhand what size/thread the spinners are?
