Question About Aftermarket Brakes

[nbrigdan]

Hi guys! I'm new here so I hope this is the right place to ask my first (and probably very stupid question! ) I was looking at jaguar XKs and performance mods, and was wondering about the interchange-ability of brakes. I saw this awesome 14.4 inch rear brake kit for a camaro (from brembo) and was wondering if these would fit on an XK..? Even if there had to slight modifications? What do brake systems depend really? Bolt pattern? (I'm having quite the difficult time finding brake upgrades for the XK and aren't looking to spend a fortune on specific ones for the jag like those from spires, I want to keep all my arms and legs!) Thanks so much for helping me out because I know I'm such a noob! I just love to learn about this stuff!

Greetings and Welcome to our TorqueCars Forum my Friend!
Good to have you along with us

You could try the Brembo brakes website and put your cars model details in.
Also look at EBC who make some nice systems. This was what I done for my very first set of high performance brakes on my Saab. If they do not do one directly for your car then there are people including the brake people themselves, who for a fee will make the discs fit. Make sure you get a brake caliper and disc kit complete to make life a little easier, also you need to mention the size of your wheels to them as you must take this into account i.e. will the new brake set up actually fit underneath the wheel. Made this mistake once but at least the garage was good about it and swapped the brakes without any dramas.

As with anything you need to work out how far you want to ( or need) to go

Brembos are a good make but there are mant others are as least as good maybe better APs / stoptech spring to mind.

Most important is what fits your car. Anything can be made to fit with the right adaptor but its better to spend your pennies on brakes rather than making something fit.

As far as wheels are concerned Ive always bought wheels to fit round brakes not the other way round but you do need to check if your existing wheels will go round what you decide to get.

Lastly serious brakes are not cheap My front APs are near enough to 14 inch and they are over £2K new for just front calipers and discs then you will have to have braided hoses and decent fluid Then if you dont change the rears to match you may need a break bias adjuster.........it goes on

Finally you dont just want an awesome set of rear brakes change the fronts first.

Considering what you have now the question is do you really need them? Sometimes an upgrade is all about looks over function and if the upgrade is not being used to its full potential will they work as well as OE ones?

Sometimes you have to really work them hard to get them to work as designed. If changing up you may also encounter ABS issues as the system is calibrated to suit the specification fitted as standard. I have found some owners' ABS system kicking in when it shouldn't. Probably not applicable to all makes but has been known.

I have thought about changing mine but for the outlay it isn't worth it unless I am racing it on a regular basis. Fast road and track days the standard set-up is more than adequate. On the flipside it looks rubbish I know!

Thank all you guys for your input!! Ill definitely go to brembo/ETCs site and check it out! Ill also check out stoptech and AP! Im just kinda dreaming up a build and trying to price it out, I think about 4-6K CDN in brakes is okay with me! And I do think ill need upgrades! Im looking at doing a XK to XKR/S conversion but with either a large roots blower or a turbo running around 9 psi on low comp. Pistons! I think its the darn specialist bits that are going to bankrupt me though!

The fronts do app 80% of the work so this is why I upgraded them and fitted a bias adjuster to fine tune the balance.
There are many forged piston available, my car has Wisecos and seem to be fine..
Why do you only want to run only 9psi on low comp pistons, how low? FWIW I have 8.7 static CR and run 18psi which some USA tuners call anything below say 25 psi low boost.
