Hey guys Im new to the forum
bought a pair of serbo brake discs from EuroCarParts for my 86 turbo
but theyre about 5mm thinner n smaller than the orinigal ones
can i still have them fitted by adding washers between the hub n the rotor
or which brand of brake rotors will fit to the car?
Thanks!

****Plus an image of my turbo[:D]

Have you got a part number? You could have been sent the wrong part in error. You' shouldn't need to shim out the rotor.
 
Certainly seems to be right from the description on the website, though the part number is not a Porsche format number so I can't check on the PET.

Does the object/part number of the parts received match what you ordered?

 
yea it matched. sadly didnt realise it until i have them fitted. also the pads can only cover 2/3 of the disc. prob going to get another set. any suggestion for drilled discs?
 
You do have a weird car though - a '96 model Turbo [&:] [:D]

Assuming your initial post should read '86 ~ are you sure it's an '86 car and not just registered in '86? Might be a different model year - one of the characters in your VIN code designates the model year - unfortunately I can't remember which one [&:]. Sounds like you have 220

Sounds like the wrong part to me. You definately don't want to be shimming out a disc to fit it. ECP will take them back if you've not used them.
 
What type of front caliper has your car got.?? It could be that somebody has fitted later "larger" calipers. IE the ones from a M030 turbo / Turbo S...
 
sure its a 86 turbo lol n it is registered in 86
i prouberbly ordered the wrong disc but they dont do any discs pre 1986 in ECP
havent use the disec but scratched a bit while installing
will ask them anyway
any place i can get drilled disk for my car then?
Cheers !
 
On a 'C' plate its almost certainly an '86 model year car. Its likely that ECP have sent the wrong parts.

I imported a car in 2001 ~ I waited until I could get a car with 2002 spec ~ even by the time it was built and I'd driven it home and registered the car it was on a 51-plate.

Conversely I've seen v6 Alfa Romeos that were built in 2003 but ended up on 07-plates by the time they were actually registered for the road.

Check the VIN - if it is right then its entirely possible a previous owner has upraded the callipers / discs. There are several different sixes of 4-pots that fit the 944.
 
Callipers and disks for Turbos are visually almost identical apart from the size so the only way to really tell what you have is to measure them:

Front pad sizes

220 bhp Turbo has pads that are 98mm x 68mm
250 bhp Turbo has pads that are 132mm x 71mm
Big Black GTS has pads that are 132mm x 75mm

Front Disk sizes

220 bhp Turbo disks are 298mm in diameter
250 bhp Turbo disks are 304mm in diameter
Big Black GTS disks are 322mm in diameter

So, would I be correct in saying that from a pad area/swept area perspective, there isn't that much advantage in moving to the Big Blacks vs the Medium (928 S4/250 Turbo) blacks?
 
Nick , I have a set of the "Big Reds/Blacks" fitted to my car,, now,, in 08 i had a set of " medium reds/blacks" fitted. After Oulton i can defo say it was well worth the upgrade....[:D][:D][:D]. Maybee not so for a road car though...
I had put off doing this upgrade , and always thought it wouldnt make that much difference,, HOW wrong was i,,,.....
I wasnt even using the FULL braking potential on Friday...Yes there was more in the "tank"....[;)][;)][;)][;)][:D][:D][:D]
 
The pads are a similar size, but are acting further out on the (bigger) disc, so can exert more leverage. The calipers are supposed to dissipate heat better as well - not sure if that's a major factor.

IMO the best brake upgrade is cooling, followed closely by PFC97 pads (just don't do that on a car with concours wheels & paintwork [:(])


 
There definately seems to be an offset issue. Either ABS disks fitted to a non-abs car or visa versa. Did the pre '87 turbos have ABS?

Maybe it is a late '86 car i.e. one of the first ABS cars and they've sent you the pre-ABS disks.

Hmm, not the answer I was hoping for....[8|][:D]

I've decided I want a 964 RS, so must not spend any more on my car......[;)]

Are you sure this is the VIN as stamped in the engine bay?
It usually reads something like WPOZZZ95Z*N10****
