Looking for some discs for track work and trying to work out my options. Fronts are easy enough to work out if they fit but not sure on the rears. Anyone know the spec or care to share any help/advice?
First option is these high-carbon Brembos although I don't know if they fit the rear
https://www.bremboparts.com/europe/en/catalogue/re...
Second option is these, which I'm sure do fit both axles

Thirdly, I'm thinking of getting in touch with Reyland and seeing what they can do. More expensive...

If you have the larger, 320mm discs, they are the same size front and rear.

Small disc cars are the same disc size front and rear (296mm dia)
Larger disc cars are the same disc size front and rear (320mm)
Calipers are the same on both options......
You can use 320mm Front discs on a small disc car with correct spacer and longer bolts.
You cannot fit 320mm rear discs to small disc car (machining of rear upright is different)
The largest discs you can fit to the oem calipers is 335mm.

This is the code for the brembo 320mm discs,
09.B352.11
Anything with the same numbers/dimenions will work (afterall its a disc of metal with some bolt holes, lets not overcomplicate it too much), brembo do drawings of their discs on their website which give full dimensions, which makes things fairly simple.
For what its worth I have the Brembo HC ones on the front and they are fine after 2 track days (after my Alpine ones got deposits on them that wouldnt scrub off, apparently a fairly common issue with them due to rubbish material quality, and I cant find someone local to skim them)

. Where did you get them from and do you know if they’ll fit on the rear ok?I've got Ferodo DS1.11 for track and DS2500 for road, the DS2500 are fine/nothing special and the only reason I use them is it means I can switch between the road and track pads without having to muck about bedding anything ever again as apparently they share the same base compound (or so Rennlist or bimmer forums say), it seems to work, nothing squeals.
The track pads are again fine, I've used them on Blyton which while having a lot of corners only really has 1 (maybe 2) fairly large braking event so not exactly heavy on the pads and then a wet day at Bedford which doesnt count. I toasted my standard pads/discs at Donnington, I would guess its a tougher circuit than blyton so its not really a fair comparison at this stage, the 1.11's are supposed to be good pads though.
I got my discs from Eurocarparts (thats where they were cheapest), they are not special discs, just sensible discs with a better quality steel, less fancy bells though. As far as I'm aware the front and rear discs are identical, so they will just fit.
For the rear brakes you need to put the electronic handbrake into service mode (see this video on how to https://www.youtube.com/watch?v=ntBqN2gNmPo&ab...), this basically retracts the handbrake system into the caliper, then when you rengage it, it recalibrates itself to the new pad/disc combo so the gap is correct.

I've also heard the same thing about the Ferodo pads supposedly having the same base compound so I think your approach is quite sensible. With hindsight I probably should have gone this route too!
My 'plan' is/was to keep the standard discs and pads for road and switch over to the XP8 with 'track discs' as needed but it would be a lot less hassle to keep the discs and just swap the pads. By the way, I'm sure I read somewhere that the standard pads are Ferodo too!

Do you/does anyone know the size of the bolts and spacers required?You can use 320mm Front discs on a small disc car with correct spacer and longer bolts.

Would like to try bigger discs compared to the small to see if there is much difference.
Cheers,

what pads are you guys using for track work?
Pagid RSL-29 (on street and track) with AP racing front discs and custom made bell by Local AP distributor. The standard Alpine discs (front) are too soft (for regular track use) and needed replacement after 25.000KM (15.000miles). The AP racing discs (two piece and floating) have better cooling, less weight and 2-3 times longer lifespan. We are with 4 friends who all own an Alpine A110 (Pure / S / Légende GT / Légende) and we all have the same braking set-up for street and regular track. Zero complaints about our set up!
What discs/pads do you have at the rear, Franzino?
And do your pads squeal on the road?
I'm talking with Reyland at the moment with a view to them making rotors and bells for me. As far as I can remember, they use AP bolt pattern so can use AP rotors, should I wish. Anyone also interested in this, let me know

The discs are standard at the rear on all our cars. Rear pads used to be the standard Alpine pads but since the start of 2023 I have Pagid RSL-29 at the rear (custom made by MP Rezeau to fit rear A110 => see pictures). My buddies have Carbon Lorraine RC5+ at the rear since this winter. The rear discs don't need any upgrades for now and don't see heavy wear/abuse. When at one point the rear discs need replacement then I will see what I will do; maybe I will also fit AP discs or fit standard Alpine rear discs again.And do your pads squeal on the road?

Concerning noise; the pads (if properly installed and greased with the correct brake grease) are mostly silent. Sometimes they give a little squeal but mostly they are silent when braking. With the windows open at low speed you could hear a small rattle when driving over potholes. I had the same experience/noise with the full stock/standard Alpine pads and discs...sometimes they made a little noise also when braking at low speeds. It's still a road car which sees also track and for me the noise is still fine on road.
By the way; Life110 is also working on a AP set for the A110.

I was thinking of having a set of original discs/pads for road and the Carbotech XP8 pads with some other discs for track as although the XP8 are fantastic pads they do squeal a lot on the road. However, it does mean a lot of messing around swapping stuff over which I'd rather not do. Maybe I should try the RSL29 on the front with the Reyland discs and see how I get on.
Just seen the price of the RSL29 rear pads
I've bought cheaper cars in the past!
I think the Reyland discs will come in at about £525 for fixed and £675 for floating and the intention is that they'll work on the rear as well as the front.
