Kind regards
Scotty
They'd overheat even if you could fit them . It would only be right to fit non vented if you competed in short motorsport events where the pads would never reach best grip temperature on vented --- like sprint and hillclimb , as I compete in .
Perhaps you're meaning drilled or grooved or both ? Personally I'd leave drilled alone as under regular hard braking cracks can appear between holes and if this happens then the disc could fly apart stripping everything in it's wake ---- scary . I found the cracks in mine before they joined up thankfully .

Sounds more like bad / low quality discs? I got both drilled and grooved discs, 3 years down the line and they're completely fine. Guess you need to watch out for the no-name ebay brands, and instead go for tested high quality.
I have a pre 2000 1.8 156 with solid discs all round. Think they may need replacing soon, is it worth switching to vented, assuming they'll fit the calipers? I've heard you can get upgrade drilled/grooved discs for original calipers- is this true?
You can switch to the 284mm vented fronts, but you'll need the calipers to go with them.
Should be easy to find a s/h pair though, all 2.0TS/2.5v6/2.4JTD had them, it was only the early 1.6TS/1.8TS/1.9JTD8v that had the smaller solid fronts.
Brakes can be solid 1 plate or vented two plate. They can also have a flat, grooved or drilled surface, sometimes flat and grooved.
Solid discs are more prone to warping due to the heat generated under heavy braking. As a result,almost all modern front brakes are vented for heat dissipation. Perhaps some pictures will help, these are from AlfaWorkshop's site who sell both OEM (original equipment manufacturer[Alfa]) parts.
Brake discs are often drilled or grooved or both. Standard Alfa items aren't, infact the consensus is that only grooved discs should be bought because drilled ones are prone to cracking. Brembo forge them with holes in which is supposed to resolve this issue but unless you drive regularly on a track, the larger surface area of flat discs dissipates heat just fine. These are drilled, grooved and vented:
In case anyone in this section takes that statement as fact I need to correct it.
For the 156, pre 2001 1.6TS, 1.8TS, 1.9JTD8v had solid front discs.
For the 147, 1.6TS 105hp had solid front discs.
I defo need assistance would someone please check the following link and let me know if these brakes are going to be any use to my 53 plate alfa 156.1.9 jtd please
Check the size of your rear discs first though.
Should be easy to see if they are 251mm or 276mm.
