I recently visited the Ring and managed to crack both front discs on my Exige S2 240. They were the AP upgrades running Pagid pads all fitted by Lotus.
Any suggestions where I can get decent replacments.
Lotus are asking �540.
I’ve also spoken to RSR who run Exiges at the Ring and say they run standard discs. I’m booking some tuition a I’m obviously to heavy on them.
Thanks Neil
I’m guessing they were drilled rather than slotted discs ?
If so just fit the same AP’s but slotted and you will be fine 
We’ve all been through a set of drilled 
Bear in mind that there are 2 specs of AP uprgade brakes. Early cars have the AP disc/spearate bells, later cars have a one piece disc made by ??? All of them drilled, because it matches the rears!! Later ones can be modified to separate disc/bell combination, and you can even get a slightly larger dics to fit 
Give us a call if you get stuck.
I have seen a set of grooved AP’s cracked ALL the way through…
The cause was down to a simple mistake by the person who fitted them to the car.
Basically the pattern of grooves on the outer faces of the disc don’t always run in the same direction as the internal cooling veins. The ones I saw had been fitted the wrong way around based on the direction the grooves were flowing and not the cooling veins… Running the veins of the discs the wrong way dramatically reduces their cooling ability which can cause a failure.
Make sure you fit your directional discs the right way round guys!!!
Thanks Guys,
I’ve got an 08 model with cast drilled discs.
I thought they may crack. I’ve spoken to Hanger but am still waiting for a reply on prices for bell and rotar discs. Plns are alos getting back to me. otus Cardiff were �500 per disk!!!
JS I’ll call you Monday.
Hi JS,
Can you quote me for bell and rotor discs for an 08 exige with AP setup.
Thanks
Neil
From what I’ve seen , Lotus and many aftermarket disc manufacturers don’t seem to acknowledge left and right ideology …
Vanes and grooves tend to be arranged according to the accountants preferences tbh …
Apart from the EBC range, all the S2 discs we stock/sell have handed discs (IE Vanes correctly positioned for left and right fitment

It’s all to do with the Coriolis effect. Left handed parts cost more to make in the northern hemisphere. The machines used to make them use more energy when having to work against the world’s rotation…

So if we buy half our discs from the southern hemisphere,and half fron the northern hemisphere that should fix the problem…
Or just turn the machine upside down…
are those the eliseparts discs? If they are the groves are cut on one disc the opposite way to the vanes to make them look ok on the car whilst only using one disc casting so cutting costs…
Pretty sure they were AP’s
I have a set of AP 295’s on the front of the Elise which are the same, veins in one direction, slots in another.
Not good practice, I’m surprised by AP 
I have always found the brakes noisy when I have had to run discs with grooves in the wrong direction.
Unlike the cooling veins I don’t think it makes any difference which direction the slots sweep through the pads. If anything if you look at it like a cheese grater for cleaning the pads then having them running in the opposite direction would make perfect sense…
Groove direction makes no difference to cooling, according to AP. When you look at all the different options they make its no great surprise. Some brands of pads do appear to prefer grooves in one direction or another. Or no grooves. Or holes. All down to whats in them.
You can always buy plain ones and have anything you want machines in them. Within reason!
Lets be honest guys, AP know what they are talking about!!!
OCD makes makes me want symmetry on my baby …
Imagine having a kid born with one ear back to front but the doctor says "its ok he can still hear well !! "
Regardless of if it makes any performance difference it still looks crap having grooves the 
wrong way on one side of the car…
AP may know brakes ,but obviously are keen to please their accountants too …
+1 for symmetry…

The grooves run the opposite direction on both discs with the AP’s, not just one side.
It’s the cheaper discs that appear to do that trick…
