Project: S2 Coupe Continously upgrade

And some brakes and coilover pics:





Old vs New rear brakes:

Cold feed looks great and those rear discs are mahoosive! Nice work.

hmmm willwood calipers too, nice and light

Have you adjusted front/rear bias at all with that setup and do you get any rear lockup?

also how you doing the handbrake with them?

[magarv]

I did a rough calculation/assumption on disc diameter/pistion diameter to get the right bias. I have a smaller piston diameter rear compared to front. In addition I bought an adjusting valve in case to much rear lockup. I have experienced it a few times, but I think the bias on the limit and just right I drove it 1 year with only the big 345mm front disc and stock rear, and that was not good
However I miss a better feeling with the brake pedal and a think it is due to the "small" master cylinder (from RS2) I would like to do something with that in the future...
Handbrake is hydraulic...

[Acidburn]

Ok cheers for the responses to that

[s2driveruk]

can you explain more about the handbrake setup......? does it just have a cylinder of sorts and flexi lines to the calipers? Dumbass question but hey thats me

What a machine, I like it a lot.

iirc it has a brake line down to the handbrake which does away with the cables and then down to the calliper, been a while since i looked into it as afaik its illegal for us to run it over here as we need and independant (cable) system to the rest of the system incase it goes wrong.

ATM I actually have no handbrake installed But I have all parts in the workshop/garage waiting to be installed.

There is no such thing as dumbass questions, if you dont ask you dont learn anything new, right?
It can be mounted in 2 different ways
The easy way is to just run the rear brakeline through the handbrake cylinder, and the advance one is with a 3-way kind of check valve. I think I will try out the easy way first and se how it works. I know it is used in rally cars etc...
I am only going to use it for parking anyway...

And we have the same rule about independant handbrake here as well

[Acidburn]

I have seen 1 or 2 cars with both fitted just to cope with the regulations here, bet its easy to get the back end out if its a fly-off type handbrake

[s2driveruk]

why not simply run an independent line and fluid supply purely for the handbrake? As i see it you would just need some kind of cylinder to pressurise the lines to apply the handbrake?

I don't think that will work... The pressure will be released trough the "main line" and back to the reservoir... (And if you install a check valve on the main line to prevent this, the brakes will not release after using the pedal)
When you run the brake line through the hand brake cylinder you will block of the main line and keep pressure in caliper. I think that is the easiest way.

Thanks

any specs of the brakes, like disc size and piston sizes?? and more piks lol we cant get enough of shiney part piks
