[Mk2] [Turbo] Turbo big brake covertion

Post by paulharry »

Hi guys
Can anyone tell me what parts I need for a big brake covertion
its one of the mods I'm doing to my 2 and if I no what parts to look out for I might be able to get a bargain or three

are you looking to upgrade the current rotors and keep the stock calipers or sticking on multi piston calipers?

either way you will need spacer brackets for the calipers and this changes depending on the disc size and caliper type.

You need to think about the size of the rotors, width of the rotors and the depth of the calipers for wheel fitment.

The ad hoc kit with stock calipers uses supra and rx8 discs but needs spacers for the stock calipers.
For proper big brakes you'll want 4 pot calipers suited to the thickness of disc you choose.
There are rear kits too and they are not to be forgotten, the selection of rear calipers with handbrake isn't massive but there is always the option of a separate handbrake-only caliper, though this can be a fiddle to fit.

Start with what wheel size and offset you are running then work out how much room you have for discs and go from there.

Thanks
I'll find my wheels first then and then talk about brakes after that
I'd like to run some deep dish 17in.I was thinking about 18in but a guy told me it would be no good for the handling
I am thinking about 9.5rear and 8.5 front or 9j rear 8j front so is there a offset what I should be looking for?
I am going to put some wide Archies on as well before I get her resprayed

Do the supra and rx8 calipers fit on the 2?
I've heard you can put the Nissan zx300 front calipers on the 2
Does any no how to do it? Or is there a better option?

This is for cosmetic reasons right ? Because the 1992+ brakes in good condition with some quality pads and fluid are all you will need ever on the road

No it's to make the car stop a little bit quicker

I second this. I recently changed my discs and pad (all oem) omg the difference is ridiculous. Almost lock up if you not careful

A big brake kit will not make you stop any quicker =; Stopping distance is down to your tyres.

Bigger brakes will resist fade under hard driving conditions as they will dissipate heat better than smaller ones. Also sometimes can improve pedal modulation depending on the kit.

I run the WMS kit on the front as its the one of the few kits that can be used with 16 inch wheels. Plus the calipers are lighter than oem, reducing unsprung mass on the front. Plus wms have managed to make a kit for the front that doesnt mess with the bias too much.

You may as well set fire to your money then.

If that was the case wouldn't all lambos have tiny little discs to save weight I'm sure if you did the math a bigger surface area and more contact and pressure on the surface area means quicker stopping but at the cost of more heat generated
All I was asking is for some advice on which Bigger calipers and rotas will go on the 2
Thanks to the guys with the positive feedback like I said earlier I'll get my rims sorted first then I'll come back to the brakes later
Thanks again

Did you use their solid discs too? how do they behave compared to vented ones in your experience?

Really I'm after a kit with lighter bells and calipers, larger isn't really the aim.

MEH ANOTHER POST WHERE SOMEONE ASKS FOR ADVICE THEN DOESN'T LIKE THE ANSWERS, may be you should check out the posts of some of the people your getting advice from, and gauge their level of experience before you refute it,...... then you use your ridiculous labmo analogy ,.... that says it all,

People are suggesting you stick with a well serviced set of standard brakes because they are generally good enough. They'll lock all 4 wheels (well, mine does as it doesnt have ABS) and they will only heatsoak after a while under track conditions. You won't run out of braking on the road.

The idea is that if you use what Toyota intended, there's a fair amount of choice of pads and discs and hoses around as options. Once you start specialising into a particular vendors BBK, you end up reducing your choices and making it harder to get parts and get them serviced.

I would also recommend getting refurbed standard calipers, braided hoses, new disks and some decent brake pads (Carbotechs, Porterfields, etc), new fluid each year.....Don't forget to replace your handbrake cables too if they are original - they're known to rust and reduce the effectiveness of the rears.

I'm not saying aftermarket BBKs are no good, I'm sure they're excellent, but they're quite a lot of money and the stock stuff is generally good when looked after.

Spend the money on refurbing shocks/coilovers and some really good tyres :)

Upgraded brakes are awesome for the track, wheel you will be making repeated hard stops from speed. They will dissipate heat better than stock, however stock 1992+ brakes are really good.

You only have two contact patches in your braking system. The pad and the rotor and the tyre and the road.

If you can lock the pad and rotor or activate the ABS, that is the limit of the force you can apply. It wouldn't matter how big your brakes are.

A better quality tyre will stop you quicker.

For some reason brake threads always end in a slanging match, if you want to fit a BBK then do research and go with how you feel once you've done the research. Those of us that have done a BBK are pretty happy with the results and the car doesn't want to swap ends. If you use OEM (from another car) calipers then parts and pads are not problem.

The argument that you can lock the stock brakes so why go bigger is just so stupid it's not even worth a further comment.

Aside from a larger thermal capacity (i.e heatsoak resistance), please explain why it's a stupid argument.

Probably because someone that doesn't comprehend decides to make condescending comments like above is the reason they turn into a slagging match.

BBKs have their place if you want your brakes to look really epic and if you want the ultimate in brake fade resistance on the track. Where you could stop repeatedly from 120mph lap after lap.

If the car is primarily a road car, a well functioning 1992+ set of brakes with some quality pads and fluid will be all you ever need. If you are driving fast enough on a public road to burn out your brakes you shouldn't have a licence.

Yeah and if someone one looked at the original post properly they would see that I never asked if stock brakes where better then a bbk or does a bbk look better then a stock kit I ask which parts I need for a bbk
your the one being condescending by telling me to go burn my money because you no better.
I will be taking the car to a track now and again



Thanks again guys for the input
Wheels and tyres first then the brakes
