Brakes?

[h4x0r7000]

Howdy, after some new brakes. new discs and pads, and maybe new calipers? after uprated ones but not quite sure what or where i should be looking so was wondering if you guys can recommend me some?

Cheers

What do you have now? You could do a lot worse than the M030 Brembo 4-pots as fitted to the later turbos and S2.

bascially its all standard. the car is a 944 turbo and its an 87

Hmmm now annoyingly isnt that the change over year for early offset / late offset? I'm not 100% sure but if you have the late offset but non M030 option brakes and calipers I think you can bolt the M030 (same diameter but twice as thick) calipers straight onto your hubs without modification?! Someone can confirm hopefully? If it is possible then this is definately what I would suggest you do. Make sure you get some freshly refurbished calipers and you will see a BIG improvement in both braking pressure and fade resistance.

I had some with EBC disks and green stuff pads... they looked like this []

If I rememeber correctly you have an '86, so you have the early offset suspension. Unfortunately that narrows your options a lot. RUMS944 is struggling right now with the very same issue on his early 220 Turbo.

If you want the pup's sacks and money is little object then you should get the hubs, uprights and wishbones from a 250 Turbo and fit them along with Big Black (or maybe bigger?) calipers and disks from a 928GTS (solid but vented) or a 964 Turbo 2 (drilled and vented) and select your pads based on your proposed use (track/road). I recommebd Performance Friction for track-focussed but still "streetable" as our cousins to the West would call it.

Assuming you don't want this to become a £2,000+ conversion you have a problem in that even the intermediate step of 250 Turbo standard calipers won't fit.

You could go for a refurb of your current ones and decent pads with new (possibly drilled?) disks, braided hoses and some decent fluid. That would give you decent fast road brakes, but would they be enough for track? Add good cooling and they might.

Alternatively you could get adaptor blocks and fit the 250 car's calipers, but that's where Dave is now on his car and he seems to be struggling to get disks with the right offset for that conversion on a pre-'87 car.

ye i thought it was an 86 but according to the vehicle doc, it says 87?

Is something I need to sort out too and given the cost of all the extra bits need for adaptation for my early car I think imroving the current set up is the way for me to go especially as I have no plans to track her (though even that parade lap at Silverstone over the weekend got me wondering...)

Do you have Porsche wheels fitted? If so the offset should be stamped on the wheel rim. There will be two numbers either size of the valve, one is the width of the rim in inches and one is the offet. Early cars are around 23mm offset whereas the later cars are around 53mm. Not sure if that means the early cars are 20mm more inboard or outboard than the abs offset cars.

I went for Big Blacks because I 'imported' from the US and it worked out roughly the same cost as buying a tatty pair of 250T calipers off ebay and having them refurbed. You also need 17" rims so if you're currently on 16" rims you'll need some new wheels.

Hi h4x,
As Fen said I have bought the bigger calipers and discs. The calipers go on easy with the adaptors but the discs don,t fit.
The calipers and discs were £300 second hand and adaptor £85. I have found a company bgdevelopments.co.uk that may be able to make or have a two piece dicsc to fit the hubs and the bigger caliper, but will not know untill they have the two discs for the sizes.
If this works out expensive I may consider lindey raceings big blacks.
