    AP racing calipers information

    Hello,

    Recently bought a set of CP2361 for my mk1, my car it's grp4 historic spec but, it will be for road usage plus in a fast road spec.

    What discs should I buy? Original (CP4136) or copys?

    What about pads? I have a set of DS3000 but they are no good for road usage so I will be exchanging them! Does anyone can suggest anything?

    Anyone have any of this parts for sale?

    Best Regards,
    Igor Neves

    There will be a noticeable difference using copy discs on a rally car am sure but for road use they will be fine

    Re: AP racing calipers information

    We have been very happily using Rally Desing copy discs on our full season rallying Escorts. That is like 700 km competetive stage kms and some testing in a season. Rarely, we have to replace them mid season, usually we replace them at the end of the season. However, these copy disc's quality may flactuate from one lot to another but still at that price I will certainly keep buying them.

    I use 266x21 so called forest rotors from RD. BM3165
    We use them with CP4567 calipers if I remember correct. I can check further on Monday but the disc info I have given is correct.

    I know CP2361 and I have those as well but I am not using them as they are needed for FIA spec car.
    These discs should normally work with CP2361 as well.

    Last question, what pads do you suggest for fast road usage in this setup?

    Re: AP racing calipers information

    First, it does not have to be the last question. I can try to be a help as long as I can.
    We have been using Ferodo 2500, Mintex M1144 and the most expensive Pagid pads on different occasions/events.
    Pagid blues are really really nice on the rally car but for the fast road work, I guess you need something to heat up fast but also not overheat when demanded so ferodo and mintex would be equally good in my opinon.
    In the rally environment, obviously we dont hear the squeaks etc etc but feeling wise both brands has been positive

    Thanks very much for the help, I was thinking in those mintex 1144, seems to me the soft ones they made, so I'm going for those.

    I also have a set of ds3000, but will not be using those for street.

    I will post up some pictures of the setup when ready.

    For the rear axel the ones I have are a pair of fiesta callipers, the ones used on diesel 1.6 and xr2 I think... Will this be a good option for the rear end?

    I will be going with 13 wheels and independent pedal box.

    Best Regards

    Re: AP racing calipers information

    I believe, you are using the English axle and no fancy set up like the FF Gr.4 hubs etc ?
    I am not familiar with those calipers but I think any rear caliper could work there providing the pedal box's rear cylinder is correct for the size. Sometimes the rear caliper is so over powered that even the bias adjusment can not limit enough to stop locking up the rears. For example front calipers on rear axle usually is not a good idea in my opinion.
    And also please note that, you need the oem type "sliding calipers" at the rear due to the fact that AP type solid calipers can have the pad knock problems with the weak single bearing on standard axles.
    I guess almost all disc conversions are based on one Ford car's rear sliding caliper in the market and of course it does not have to be a Ford caliper.

    Re: AP racing calipers information

    Gr2 or 4 ? ( both cases you can have disc brakes )
    FIA historic or local historic ?
    In FIA historic car, you can not just use ANY caliper, it has got to be the correct ones. If I remember correct CP2382/83 or CP2577 but twin.

    Re: AP racing calipers information

    Thats all very good but also I am not sure about Watts. I must check on Watts.
    I believe, Panhard is the homologated item along the slipper springs. There are small differences between the Mk1 and Mk2 Gr.4 homologated cars.
    I assume, you have the BDG engine, Rocket 4 speed or ZF 5 speed box.

    No, only the chassis will become GRP 4 setup. Gearbox and engine are still small (Pinto and type 9).

    I need to put car running before thinking in those upgrades.

    I have 711m, the idea it's too find one bda head and make one 1800 out something like that in a future.

    It's not competition, it's fast road max track day car!

    Re: AP racing calipers information

    Ok, understood. I use Watts on our cars at the rally but unless you are taking the springs out then it is an overkill. Panhard does its job quite well.
    I think, a BDR engine can be based on 711m block. Nowadays, parts are getting more reasonable.
    Type 9 should be replaced with a Rocket then for the proper FIA historic set up if thats the idea or ZF but not quite needed.
    Referring back to brakes, I think you better use the proper calipers if you are on the Gr.4 FF hub set up. But if your diff is a Non FF ( which is a Gr.1/2 Atlas in that case ) then I can find out for you the correct calipers.

    The idea it's to go for GRP 1 / 2 setup. No ff for now.

    It's the narrow atlas, with the small bearings...

    For now I will go type 9. Next probably or rocket or gear kit for type 9. The car runs on the street, 5th gear it's nice to be there.

    Concerning the brakes, before I got the ap's, I was going with Volvo 240 callipers and BMW e30 discs... Now I have this and obviously want to use them.

    I have to think on the options for the rear...

    3 litre Capri drums on the back would make it historic legal also.

    Yes, I think I have 2 sets of those but I really want to use discs and not drums.
