i will give it a go trimming them down, but the other alternative is to use some 345mm discs and manufacture some more components to space them out even further to suite the extra diameter of the disc!
would it be possible to contact EBC or mintex to see if they are willing to make some slightly smaller pads by adjusting some numbers in the cnc programs? is this a possibility?
I would not go any bigger, personally I wouldn't have gone this big on what I assume is a lightweight car ?
Don't overbrake it, but for pads I use EBC yellowstuff, ebc will not do a one off pad as just not financially viable.
You may find redstuff ceramic, better with the lighter weight as they work slightly better sooner, the problem might crop up with track pads about keeping enough heat in the brakes with a light car.
Lotus even used silicone carbide reinforced aluminium metal matrix MMA discs, which were vastly better all round(288mm size,elise) apart from one annoying habit, which was MELTING when they got too hot, up to that point worked fantastic.
Disc make is very important too, as some are now using, very little pig iron in the discs so are even better for thermal cycling.
