Boxster brakes

[Guest]

John,
When I did a brake over haul on my SC the Boxster kit wasnt around, but I have talked to a few people who have,they are all very impressed with it, when I checked on the cost it was about as twice as much as getting Classic to rebuild the originals and fit new discs (I paid 54 pounds a corner for the calipers to be refurbed) and I know Bones stripped and replaced the seals on his, so I suppose its down to how big the money pot is.

See this thread + I'm sure there are other previous ones.

I have done the Boxster front caliper upgrade with cooling ducts & am very pleased, but unless your "enthusiastically" tracking your car this may be OTT.

Thanks Andy, have been reading up on Pelican regards the brakes and think the Boxster set-up is the way to go for what I want. I don't want to spend £400 sorting out the standard set-up when I could spend a little bit more on a big improvement and make the car more driveable by giving myself more control through the middle pedal.

I have no plans to track the car this year but might well do in the years to come, so will budget for the expenditure now and get future-proofed. My long-term plan is to build a full-on track bandit SC one day in the far far future, so if the Boxster setup is overkill can always switch it to that (though would prefer to go Turbo brakes on it)

Will likely do the duct mod also, that front valance on mine not got much longer to live

Cheers for the link btw mate []

Cheers Mark,

Money pot not massive, but the way I look at it it's a false economy refurbing standard when you didn't think it was up to much to begin with. Am just looking into it at present, some good deals in the 'States and the exchange rate good too so who knows...[8D]

I have this cooling duct system

http://www.paragon-products.com/product_p/bd-5600.htm

The air is collected by the shoe that sits below the wishbone as opposed to from the front PU. This was important for me as the Club Sport has no holes in the front PU for spot lights etc. & I didn't want to go cutting any.

The Boxster calipers are more easily sourced (got mine for £250 the pair from a scrappy) than Turbo calipers & will work with either the standard 282mm dia by 24mm thick Carrera 3.2 discs, or with the 298 by 28mm 944 Turbo discs that I have & still fit within 15" rims. So with 16"'s you might even be able to go larger.

Thanks Andy,

I have settled on the Boxsters also mainly because of the greater availability.

Would be great to get some bigger discs in there. The car will lock in the wet with BIG pedal but in the dry it's just not good enough, way too much rear bias also with these fronts underperforming so refurbed four-pots the way to go IMO. Would be great to get some bigger discs in there too, will have to do more Pelican digging to see what others are running. Bought some braided hoses and a decent monoballed strutbrace for the front from Ian H so will be interesting to see how much firmer we can get a cabrio withoiut caging it. Bilsteins and Michie Sports all round also on the shopping list for next year.

I think we will fabricate the caliper mounts and the duct kit, that Paragon setup looks really easy to replicate using the standard backplates and I have a fabricating genius for a best mate so he will do that easily. Will get him to look at it and if he says it's about as dear to make it ourselves then will go Paragon.

I don't want to hack into the valance either, would rather keep the front end smooth. Not totally gone on the 3.2 valance foglight/duct thing but then have not yet seen it done properly in my colour so will start looking at that next I think.

What have you done on the rear if anything and what size rims are you running? I thought the CS had 16's?

Rear calipers & discs are standard Carrera 3.2. I did think about putting the OE front set up on the back, but what with the adaptions required to fit + the likely requirement for a larger master cylinder I didn't bother. Even with a 911 the fronts do most of the work anyway.
The rears do have Pagid Blue to match the fronts, but that it.

I run 15" rims for track, standard 16" for road.

 

[Guest]

Thought you might have been running 15's off the road, will have to come and watch you guys at work one track day. Gonna start looking for the Boxster bits now.

Cheers Andy.

John forget the Boxster stuff; Buy yourself a set of 930 calipers, disks from a breakers and a new master cylinder and the bugger will stop on a sixpence without cooking the brake fluid if you have the ability to use the stopping power available. Get some extra cooling ducting put in there for track use. []

 

[Guest]

Might do it if I can find the bits at the right price, tasty looking bits of kit. Just seen those 930 bits sell for $1700 on eBay though

*gasp*cough cough cough

Bones, are you watching the East African Safari rally prog on Motors TV at the mo? The 2003 Classic event with pre-72 cars only. 20 911's in it! COOL!!!!

 

[bones]

Damn I would be watching it if I had that station! Ring round breakers for prices on 930 brakes, you can get them for less than that. Try Pro-9.

 

[Guest]

Porshapart want £400 for set of four Boxster calipers, not bad but then have to sort fitting kit and refurb inc new discs and pads on top of that.

Struggling to find someone with the (preferred) 930 bits but am not known for giving up easily [8D]

My SC had a boxster brake conversion installed by the previous owner.

It used mounting adaptors bought from a popular source.

Following some brake judder issues after the last 'RIng trip I decided to overhaul the front suspension (with elephant polybronze bushes etc).

When examining the brakes I noticed the calipers were not centred on the disc, were also not perpendicular to the disc and had threaded rather than shanked bolts.

The mounts have been made incredibly shoddily and the result is dangerous.

Really worth checking your brakes if you have had this conversion done!

A friend had the same issue on a 964 using similarly sourced mounts.

 

[Richard Dawson]

Just to add, the chap I bought the car wasn't at fault .

He bought kit from a shop for Porsches in good faith.

It is the suppliers of these parts who should have a really good word with themselves.

Sadly some shops for Porsches never learn and consistently sell rubbish.

Yep, I have seen these mounts that some Shops for Porsche sell and they are 3rd grade metalwork items, dangerous as you say!
