I have a 2.0 16v TS 1996 (UK model, at least I dont think its and import)which needs some new front disks.
I check on the internet for prices and find conflicting evidence as to whether the disks are supposed to be 257mm or 284mm. I measure the disks to see what my car is fitted with and discover they seem to be the larger ones, Its dificult to measure accurately without removal, but they were definitely bigger than 257mm I measured 281mm approx . I contact my local auto parts shop who say they should be 257mm. I then contact my Alfa dealer (expensive) who indicates the replacement front disks for all 1.8 and 2.0 155's are the 257mm disks.
Although I dont realy want to downgrade my vehicle to smaller disks, the smaller ones and matching pads are widely available and inexpensive unlike the larger.
I assume that the caliper and hub are identical on either arrangement and that I can fit either the 257 or 284 disks with matching pads. Does anybody know?
If anyone has the answer to this I think it would be useful not just to my self but to others with 1.8 car wishing to upgrade disks
who I assume may be able to fit the 284 units.
You have right size when your disks are 284 mm, but... remember to measure your middle sections hight. It should be 39 mm not 44 mm as they are in v6 an Q4-turbo. Yes! v6 and turbos have 284 mm disks but they really are higher in middle part of the disk!
I got disks which were from Fiat Coupe turbo 20 v!
I have a 97 1.8TS 16v and will soon be needing to upgrade my stoppers. Which options do I have? Is it just a case of buying some drilled or grooved direct replacement discs and pads or can I go for something bigger???? Any suggestions?
You'r car is born with the big disk's,so my opinion is,that if you're only doing road driving,it is not necessary to go bigger,just better,like TarOx or Brembo.If you occasionally doing track's of some sort,then it's a good idea to bye bigger disk's.
Ex. 310 mm disk's only for roaduse is after my opinion just "styling".
On the subject of bigger disks.. I'm running the standard 15" wheels on my '94 Silverstone. Does anyone know what the largest disk I can get under the wheel is? Obviously I will need different carriers to move the calipers out - are they interchangable or do I have to find somewhere to make them for me?
Acording to Tarox,they make 3 different bigger disk's for our 155'er.310 mm,318 mm and a 330 mm.If you bye one of theese kit's,everything needed for this conversion is in the kit.Tarox say's that for the 310 mm disk is a 16" wheel the smallest.The two other demand's 17".All 3 kit's are with 6 pot calibers in front.
I phoned the Alfa dealer again quoting Chassis Number and he confirmed that my car (2.0 16v 1996) should have 284mm
disks. It seems that the 8 Valve cars have the 257mm disks standard but any car with the Sports pack and almost all 2.0 16v cars have the 284mm disks. Not sure on the SilverStone model. Aki tells us that the 284mm disks on the V6 and Q4 are not the same as the 2.0 16v and these will not fit the other cars in the range, as the centre diameter is 44mm not 40mm. If you are unsure which disks your car has its pretty easy to measure them even without taking the wheel off as the diference is about an inch between the 2 sizes, alternatively phone your Alfa dealer and insist on quoting your chasis number for him to make sure he can tell you which disks your car should have. If he quotes an astonishing £88 per disk then you have the bigger ones The smaller disks are almost half the price. If you have 284mm disks it seems the sensible option is to order Fiat Tipo 2.0 16v disks and pads. The centre diameter will be 39mm so they should fit the 2.0 16v. I would hope these can also be used as an upgrade for the cars with 257 mm disks, Any one done this?.
I am assuming the Tipo 2.0 16v caliper is the same and takes the same pads.
Regarding Competition Pads v Standard. I understand that Competition Pads work at higher temporatures.
You might just assume that these pads are better all around but I understand that this is not necessarily the case and that the competition pads are actualy less effective until you get them hot when ofcourse they are better. Hence for those of us not perminently burning rubber are we better to stay with regular pads but buy slotted disks.
