big brakerotor upgrade

Is there anyone who makes adapters for a bigger rotor upgrade in the front?
Don't want other calipers just want to use bigger rotors like 330mm.
thx

You can always fabricate an adapter, but it's not really worth it in my opinion unless you modify the caliper to take a thicker rotor as well. A larger diameter rotor will give slightly better braking torque, but won't help much with brake fade. A thicker rotor with better heat dispersion is needed for that. There was a company around years ago that had a kit that widened the caliper and had an adapter to fit in a larger, thicker rotor, but I don't think they are around any more.

Do you have 93-98 Spec or 99 Spec calipers?

99 spec calipers can take a 32 mm thick rotor. For better heat resistance, you want a thicker rotor, not to increase overall diameter per-say.

I recommend upgrading to 99 spec calipers if you want to keep the OEM FD pad shape, and as close to stock as possible. Then you can upgrade disk size to 320, 325 or 330 mm from the stock 314 mm if you wish then. All you would need to do is make a bracket and a bell-housing for the 2 piece rotors. 99 spec rears to match the front disks would help as well to keep the brake balance.

Keep in mind you have to adjust the friction (mu) level of the pads front to rear once you have done all your hardware upgrades to suit your driving and car.
