Looking good and same setup as mine. Not tried it yet but hopefully a improvement over the old brembo caliper.


I take it your running Ap 4 pots up front?

[Aerodynamic]

What handbrake caliper is it? And what brakes did you have to mount both calipers? Any pictures?

[Singingwolf]

The handbrake caliper are made by italian guy "steffen"; i bought it used in German. You can find more info Here on vx220.org. On the rear I have mounted the ap calipers 2 pot with ferodo racing ds2500 + handbrake calipers; on the front ap calipers 2 pot with ferodo racing ds3000.

Your crazy 😂 Having AP 2 pots front and back and different pads is going to mess with your braking bios.

wild not this setup could lock the rear wheels first ?

[Singingwolf]

I received info from some guys in Italy that have this configuration and the car works very well! I have to try and I will give you a feedback. Has someone tested my setup? For example haggi961?

Just your braking balance will be crazy. The fronts do most of the braking and around 70% ish. If more braking done at the rear then it would be very twitchy going into corners. With changing to 2 pots front and back you will upset the car and also different pads front to back is never a good idea. I'm running the Ap 4 pots on the front which the 2 pots rear and cl5 + pads all around.

that's a very sweeping statement to make...

 

it varies a bit car to car depending on tyres/springs/etc. but ideal is closer to 60/40 and for a track car (and pretty close to the standard setup), 55/45 (and even more on dedicated race cars - I ran 2 pot AP's all round for the 24 Hour)

 

that said, if you do this you really do need a bias valve fitted to 'limit' the rears at high brake loads, and if it was me for a road car, I would use the smaller pistoned AP 2 pots (they do 41.3 and 38mm versions)

Be wary please...

If different pads front and rear is so bad, why do Elise parts sell that set up? Need to be careful of massive generalisations here

bit late for this thread!

 

As usual, too much stuff is quoted as de-facto rather than misguided opinion.

You do know what happens when the rear wheels lock up first don't you?

It can be used as a way to adjust brake bias, especially in a race series where your not allowed to fit an adjuster. Around 2009 in the MX5 championship, EBC were the control pads, so people would fit yellow stuff at the front and green stuff at the back. Its abit pikey but it works in some cases.

Yes,thats why I ask.

[SteveA]

Even mixing pads for ones with 'similar' compounds made mine swap ends at 100 mph and propelled me into the armco, be careful.

[D-DAWG83]

I run AP4 pots with CL5 pads, and the standard calipers with CL6 pads, and it seemed ok on track, though that is totally different to the OP

[CAHILL]

Change of subject, I'm impressed with the condition of your subframe and wishbones, are they original to the car,

I don't think that is what actually sent you into the armco.

 

It is common in competition cars to have different pads front to back.  Front brakes operate at different temperatures to the rear so even the same pad material will be displaying different characteristics.

 

As "Skuffers" suggests, there are many things that can upset brake balance and several different ways to correct it.

[SteveA]

What do you think it was?
