Powerlite calipers
Fiesta_Jed - 26/4/13 at 11:01 PM

Hi everyone, this is my first post on here and I have a brake related question.

Has anyone used a wilwood powerlite caliper with a 24mm thick disc ?

Thanks

I think they specify up to .86", i.e. 22mm - you could probably grind a bit off the pads if necessary to get the remaining two mm. Probably easier and more cost-effective to buy discs that fit though?

Hi, I should explain that the calipers are not for a kit car but for a mk2 fiesta.

Im trying to fit 260mm discs and 4 pot calipers under 13" wheels, Not an easy task with a FWD et.

If anyone knows of any other 4 pot calipers that are a similar size to powerlites could you let me know ?

Thanks in advance

Cant you just buy a set of wilwoods for your kitcar mate?

Got example mine bas cortina front hubs so im buying the cortina wilwood kit from Rallye Design.

Powerlite calipers are only suitable for cars weighing upto 750kg.

I'm sure a Fiesta will weigh more than that?

Fiesta_Jed - 27/4/13 at 11:12 AM

The fiesta should weigh no more that 850KG .

I know that compbrake caliper that were rated for 750kg worked fine on a mk1 fiesta with full interior etc so The wilwoods Should be fine on my stripped out mk2.

Im only asking on here as I though powerlite calipers would have been a popular choice for kit cars.

So has anyone tried a 24mm thick disc in a powerlite caliper ? did it fit ?

Thanks

I have midilite calipers on 260mm vented discs under 13" pro race 1.2 wheels. So it can be done.

Hi, what are the offset of your wheels ?

Also how tall are your brake discs ? mine are currently 53mm (2.9 xr4x4) but im going to incease them to 58mm (s2 rs turbo)

Do you have any pics ?

Thanks

Thanks.

What hubs are you using ?

A standard mk2 xr2 fiesta weighs in at about 800kg, so a stripped track focused one should be easy enough to get under 750kg.

Sorry for all the question but just to confirm, Your wheel actually touches the brake disc like this ?

and you dont have a thing like the gold bit in this pic ?

How much brake clearance do you have ? I imagine that it must be tight

just a word of caution, using calipers undersized for car will invalidate road insurance pretty quickly.

I would hazard a guess that they 'limit' to 750kgs because they aren't stressed to take particularly high line pressures/pad forces. These sorts of billet machined aluminium calipers will naturally fatigue relatively quickly and pushing past the recommended limit probably isn't a good idea.

That said, I would run them as long as it was without a servo....
