Yep

This is our Impreza:

Is that the RA in your plus profile? Do they have the same sort of brake set up as a UK, i.e., will my wheels fit onproperly?

Forgive my ignorance, this aint my area of expertise.

 

As much as I wish I could, I`m in Guernsey Just trying to find out the implications of running spacers if I had to.

 

Theyre exactly the same. Just make sure you phone upfront if youre coming to see us so the car will definately be here for you

This info should help

356mm rotor with bell and fixings 8.8kg
330mm rotor with bell and fixings 7.6kg
Front 8 pot caliper 2.8kg
Rear 6 pot caliper 2.4kg
Total 356mm diameter needed inside wheel 400mm
Total 330mm diameter needed inside wheel 375mm
Measurement out from hub face to outside edge of caliper 32mm

How much room do i need from the hub face to the spokes? I believe Kev gave me some measurements and one was 84mm required from back face of rotor to inside of the spokes. Is that the same thing?

The reason im asking is because at present and based on the measurements Kev gave me, ive got 1mm interferance between my spokes and the caliper.

 

Measurement out from hub face to outside edge of caliper 32mm. Ive no idea where Kev got 84mm from, Ill have to ask him to clarify what hes talking about.

EDIT: Its ok, its as he said, from the back of the rotor to outside edge of caliper is 84mm, I measured from a Subaru Impreza GC8 hub face to the outer edge of the caliper which is 32mm

My measurement is far more useful as its car specific, Kevs measurement is fixed for all cars BUT without knowing the offset of the bell you dont whow there the caliper will sit in relation to the hub and therefore isnt of huge help.

I could only do the proper hub measurement because I have an Impreza

 

I'm even more confused now. I dont think my current discs are standard either, so they may not have help when i measured then?

 

Forget everything Kev said, lets start again with car specific measurements seeing as we have them to hand.

The distance between the hub face and the outside edge of the 330mm KSport caliper is 32mm. Id take it that your disc is about 6mm thick in the centre where it meets the hub. If you measure from the ouside edge of your disc (where the wheel touches the disc) then youll need 26mm clearance from that point to the inside edge of the wheel. Obviously the caliper sits out from the centre of the hub so you need to take the measurement around 180mm out from the hub centre, radially speaking.

Radial measurement

Distance needed between outside face of discs where it meets wheel and outside face of caliper

Is that clearer?

 

Is that the same for the 356mm caliper?

 

Ive altered the radial measurement, please check again.

356mm hub to outer caliper face is the same, obviously the radial measurement is different. Youll need 400mm total inner wheel clearance or 200mm radial based on radius as in pic in above post.

Phew, am I making sense here?

 

I dont really follow you im afraid.

 

Look at the front of your car and picture the cars brake disc attached to the hub. Now imagine the disc face where it meets the cars wheel. When you fit the KSport kit the caliper will sit further out compared to the disc/wheel mounting face.

The distance between disc/wheel mounting face and outer edge of caliper is 26mm.

Any clearer?

I need to get some pics to clarify but my Subaru isnt here at the moment.

 

Are they 17's on your scoob Bren? cause i think there the P1 alloys the same as mine, If they are i know for sure the k sports will fit under fine

Thanks

Darren

 

Thanks Bren


Dougie

 

Theyre Rotas but the P1s are the same as OZ Superleggeras arent they? Theyre well known for their brake clearance

 

Whats the bedding in procedure then? I am used to the violent ways of the StopTech's. So how to bed them in?
I am tempted for rears as well, LOL. Oh, decisions, decisions
So do i or dont i? Would it still be a balanced setup with 330's on front and rear? Does it affect the ABS?
And apart from that, i await eagerly to get them.

 

I have approx 8mm clearance on my BBS LM,s on the existing oe 4 pot caliper....is there a measurement on how much bigger the K sport caliper is over the oe subaru 4 pots???

 

Ive done some more measuring, sent a PM and will phone tomorrow (again).

 

will these fit over 18" rota tarmacs on a MY99 with oem 4 pots?

 

I think one more dimension is needed along with the ones you've given already. You have given the overall radius of the kit (188mm for the 330mm kit) but could you please give the radial dimension to the inner point of the caliper?

On my wheels, the further out you go towards the rim, the greater the distance from inside of the spoke to the wheel mounting face. I've got nearly 30mm at the 188mm point but this rapidly decreases as I move towards the wheel centre.

 

I had a similar conversation with Bren yesterday - read this post and the ones that follow. Or give him a ring tomorrow to clarify.

 

What's the ETA on these?
Also, as a complete n00b, what do I need to get in preperation for fitting these myself? I've done it before on my old Scoob, but that just invloved handing stuff to a mate whilst he did it for me, this time I'd like to do it myself.

 

i just noticed that the money's gone from my card today, so hopefully soon

 

We ask customers to do a good 400 hundred miles of progressively stronger braking to put the rotors through plenty of heat cycles. Im not talking about 400 motorway miles and then go on track, Im talking progressively stronger braking so the pads and rotors hit a higher peak temp over the 400 mile period.

Do you have that same clearance with the caliper mounted further out, bearing in mind that the KSport are 330mm diameter? Im assuming youre thinking of 330s. Let me know and Ill get the info for you

I havent tried those wheels personally so cant guarentee anything, the KSport caliper face sits 34mm out from the wheel hub face so its easy enough for you to check

The calipers are 75mm tall

The boats docked in the UK, the kits should be with us late next week but no promises at this point in time

You need to ensure the hub face is very clean with no contaminents or rust so the rotor and bell aseembly can sit flat. These brakes, as with all kits irrespective of brand, should be fitted by a properly equipped garage who know what theyre doing with each rotor tried in the 5 different rotational fitting positions to find the lowest run out.

The spokes on the inside of wheel don,t curve in at all so at 330mm it would still have the 8mm clearance...??

 

dumb question i know, but these will fit under some 18" inovit STVI's
I would of thought they did, but on the site they listed on, they say fit subaru's but not those with big brake!!

 

would have thought so, if they go under newage wrx rims then surly they will go under 18's...iv got the same rims!

 

So is everyone else having them professionally fitted?

 

any chance of posting the measurments for the 304mm kit please bren or can you tell me if the will go under volk te37's in 16" ?
