OEM AP rotors/alloy bells with princess calipers etc...

[keri]

I'm toying with the idea of doing rotors to replace the AP ones that were fitted on alloy bells on some late wedges....

I seem to remember people saying they were no longer available, and that by now most needed replacing!

Also if there are enough people with the princess caliper on 2.8i Granada discs I can probably sort out both a one and two-piece disc to sort the pad overhang issue. (like the AP/alloy bell solution does)

Let me know your thoughts, if no-one replies I'll know there's no demand and I won't worry!!! :-)

...and you didn't even mention it!!! I've a princess setup with pad overhang...and wierd caliper offsets.

Sorry dude! It's because I'll need a borrow of someone's old AP rotor, alloy bell and widely spaced princess caliper... I seem to remember the AP rotor were 28mm thick, the 2.8i based ones are 24mm thick.

I can possibly do the spacers and bolts etc to do kits to fit the princess caliper round the AP width discs, and the bells and rotors as well...

It just depends what people want!

If you had posted this a couple of months back you could have borrowed mine. It's all back together again now and I don't want to take it apart again for a while! I would be interested in a set of rotors though to keep as spares.

can you work out a system were the disk is connected on the out side of the hub so the wheel then becomes a nice big heatsink than the system at present were the heat of the disk go into the wheel bearing

Keri, depending on price I could be interested in a set of rota's. Don't need any at the moment but I know when I do I'm not going to be able to source them.

Superb idea.. mine are OK at the moment though..

Might be worth you talking with TVR parts.com - who might like you as a contact for this..

It's a bit of a chicken and egg situation this unfortunatly - I'm need to get my mits on some old discs / bells before I can make anything to work with them....

Does anyone have this setup on a project car that's currently in bits?

The last 2 sets of rotors I've had have been made for me, 1 by Tarox (groved) and one by a co. in the Midlands (name eludes me for the moment) using AP blanks and also grooved. I'll dig out some prices for info. over the weekend. I think I've also got a pair of the old rotors somewhere (they are 28MM), but the bells / calipers are being used on the car!

Ah ha, do you think I could borrow your old ones? At least then I'd have the info I need to create more...

Does anyone have any photos of the bells? Specifically, do the rotors locate off their inside diameter (onto a protruding "lip" on the bell), or off the mounting bolts themselves as many seem to?

You're welcome to one of my old rotors. P.M. me - I'm in Kent.
The last set I bought were from BG Developments in late 2003- worked out at £124 per rotor plus vat, which were machined from AP blanks and then grooved.

Blinking flip!

I'm in the process of doing a prototype brake upgrade for the AP 270mm rotor/alloy bell equiped cars (biiiig alloy CNC 4-pots to replace the dreaded princess anvils), having finally got hold of some 'SE OEM rotors/bells. However, while the rotors are in good nick, I suspect they have been machined as they are in fact 269.5mm x 26.7mm...

Has anyone got the AP part number / drawing / new AP rotors so I can get an exact-and-confirmed new thickness? They are referred to as being 270x28mm, but to get a perfect fit I could do with a few measured examples (via digital verniers idealy, +/- 0.1mm would be about right)

Cheers lads! :-)

At the mo mines got Tower View 300mm rotors and Princess calipers. The offset of the caliper to the rotor is really bad. I'd be intersted in rotors and calipers, but would prefer 300mm rotors as it's got Cerbie wheels and the smaller rotor would look a bit woosie. The above lot did fit in the original wheels, but it was tight.

[Keri]

Hi deetes, so are the 300mm rotors on yours (a) fitted directly to the TVR bells, (b) fitted to aftermarket bells or (c) one-peice brake discs?

My plan was to try and offer (for people with the OEM TVR bels fitted):

Step 1: WMS 4 pot calipers/brackets to fit as an optional upgrade
Step 2: 270mm straight replacement rotors
Step 3: 280/300(330mm even?) bigger rotors still to fit the TVR alloy bells, and WMS calipers/brackets to fit.

Keri,

Mine are one piece discs. It sounds like I would need the whole lot if I were to change, ie rotors, bells, calipers and brackets. This would, probably, be horribly expensive. I would be interested in finding out how horrible, as the current setup has been on the car for 10 yrs.

With this particular idea I was going to enable people to re-use their existing alloy bells for the originality factor, I don't have a cost for WMS bells as they are so deep... (lots of material milled and thrown away)

We'll be looking at a few variations on the theme, just seemed that the 270mm stuff was a good starting point due to the weight of the Princess calipers!

I guess this (below) sort of sets the benchmark for prices etc.
I've been considering the 295mm option that seems OK for 15in wheels - 300mm is very tight for 15s

Hope you give better customer service. well not sure you could give worse.

It really depends on the wheel. Some motorsport alloys take 300mm, even 310mm, but most will only take 280mm leaving a 2-4mm radial clearance.
