Just been looking at some of the Wilwood direct M16 replacements and Rally Design list 2 types.

Wilwood Powerlite at £99

and

Wilwood Midilite at £149

I've had a look on the Wilwood site but I can't find any details of the Midilite on there only the powerlites so does anyone know what the difference between the 2 are apart from £50?

Its all down to the the weight of the car.

I have the Midilites fitted and my car weighs 600 kgs dry.

I think the Powerlites cater more for the lighter-weights(eg BEC`s)

i think the Midis can accept a bigger brake disc than the Powerlites. The other difference is also....i think....the Midis can accept vented discs. Might be wrong though.

Thanks for the replies.

The both can accept Vented or Solid discs according to RD: http://www.rallydesign.co.uk/advanced_search_result.php?keywords=M16+wilwood

Just makes me wonder about them not being listed on the Wilwood website. So I can't identify the differences. And the RD site doesn't give any warning as to weight limits.

I have Powerlites fitted to my MK Indy-Blade which has drilled and grooved disc's, you have to apply firm pressure to the peddle unlike my tin top but it's good when you get used to it and never fades on track days etc. I believe that vented disc's will warp if exposed to heavy sustained use such as track days etc.

I don't know the answer to your question,but I have powerlights,came stickered up "not for road use",and I can only assume that's to stop everyone else running up the back of you! That said before the Striker I had an imp on drums all round,a discovery,and a 200sx,none of which were designed to stop in haste.

Some brakes come marked not for road use as they don't have any dust seals and manufacturers don't want the warranty claims.

The Midilite is available in larger bore sizes than the Powerlite

As above, the cheaper of the 2 have no dustseals, get the dearer ones, it will be better long term

the midilite is the bigger brother of the powerlite. i have powerlite's on my roadster pushing +200bhp and i cant get them to fade even with a bit of track abuse.

As has been said, the Midilites have dust seals and are fine on our crap covered roads, i've had them on the front of my car for several years now and they fine.

I'd be slightly cautious of using calipers without dust shields on the road.

Don't forget thats £149.95 + £30 vat, I hate companies who advertise prices excluding VAT then you've got vat on the post and packing

Powerlites are limited to vehicles <750Kg, so they say. They're a lot smaller than the midlites. But then if you want a handbrake mechanism, it's only the powerlites which have it as far as I know. So I've got middies on the front, powerlites on the back.

Not sure about the M16 ones, but for ford fittings you need an adaptor (just a drilled chunk of ally) and some spacers:

(More pics here if it helps.) I found the whole thing pretty confusing tbh as there isn't much information out there.

The guys at Rally Design are pretty helpful if you talk to them though, so worth giving them a ring.

The midilite is a bigger caliper and uses different pads. There are less 3rd party pads available for the Midilite compared to the Powerlite. I changes from Powerlite to Midilte as I was melting the discs on my Phoenix (due to the discs being enclosed in the body) and decided the larger disc/caliper would help.

If you are running a 7 type the Powerlite should be fine with the solid disc.

Theres £200 difference between the powerlites and midilites.

Even more if you buy them through Rally Designs website.

I did a bulk buy a little while ago, which I can still get at similar prices.

I see a £50 difference between the 2 on the Rally Design Site.. £99 and £150 for the M16 direct replacements. Where do you get £200+ difference from?

Ah I was thinking of the brake kits for the cortina they do. Discs, calipers, spacers etc.

You also need to be careful with RD because they don't say if that's for one caliper or two.

It says m16 replacement caliper for £149 but then later says caliper(s)


If it is just one caliper the cortina brake kit works out cheaper

I have escort uprights so cortina is no use (unless they are the same)

All RD calipers are priced EACH, plus VAT and plus delivery. So not far off £200 difference
The Midilite calipers will take all the pads the Dynalites take, with just the backing plate modified slightly - very easy to do with either a jigsaw or angry grinder.
The Powerlites are only recommended upto 750kg, then above that you really want to be using the Midis.
Also, the dust seals dont mean you're getting better calipers. The calipers without dust seals usually come with stainless pistons rather than aluminium, so they dont corrode. They just need a quick scrub with a toothbrush before you push the pistons back in so you dont push the dirt back with them. The dust seals may be fine on the road, but if you put enough heat through them, they will catch fire

I've been selling custom brake kits designed with Wilwood calipers for around 5 years now and never had any issues with the non-dust sealed calipers. I even run a set on my MX5.
