Do try buy from club traders when possible!
Mintex extreme are just ever so slightly better than standard! No were near good enough for track use!
They will get to hot, wear very quicky and fade after a couple of hard laps!
So competition grade pads are best suited, But they are pricey so just put them on for the track and keep your road pads for afterwards!
Changing pads is so easy! Jack the up front end , use axle stands or blocks of wood for safety, take off the wheels, gentley squeeze the pads away from the disc untill they are as far back in the caliper as possible on both sides of the disc, check that your fluid isn't over flowing from the reservoir, if it is, soak up with kitchen roll and rise with water, then remove the clips/pins that hold the pads in *be carefull with the spring when it releases*, then remove old pads and any slim metal plates that are behind them, Put it all back together the way you took it apart, and make sure you don't forget any parts! Do one side completely then pump the brakes to drop the fluid level in the reservoir, then go at the far side!
If you need new fluid, get yourself a small bit of about 4-6mm wide rubber hose that fits tightly over your bleed nipple, start with the back passenger side caliper open the nipple and get some on to pump the brake pedal till the reservoir is very nearly empty then put abit of your new fluid into the recervoir and keep pumping till the new fluid is bled through, then close the nipple, Do this on all 4 calipers making sure never to run the reservoir dry! Then fill the reservoir with new fluid, Then back to the back pasenger side caliper, have someone pump the pedal couple of times till its hard , hold it down, then loosen nipple but try close it again before the pedal hits the bottom, do this 3 times at each corner, making sure not to forget that the front calipers have 2 bleed nipples on each one! Give your calipers a good clean while your there and your DONE!
***VERY IMPORTANT***
If you're not absolutly sure you can do this then don't chance it, they are your brakes so you're fooked if they don't work! leave it to the pro's,
Use the rubber hose to pump the waste fluid into a coke bottle and then dispose of it responsibly,
Brake fluid is nasty stuff, mind your driveway, your wheels, body work and hands! brake fluid will fook with all of them!
Soak up spillages with kitchen towel quickly and rinse well with plenty of water!
I'm sure there are quicker and maybe better ways to do all this but this is what I do!
A bit of work in it but well worth it if done properly!
Best of luck!
