rear rotor diameter?

Having some difficulty getting my rear rotor kit sorted out, the company that supplies EBC pads/rotors here is insisting I've got the wrong kit selected, and there is conflicting information all over. I know (think?) they switched to outboard in the mid 90s?
Car is a 89' with inboard brakes.
Most websites show rear rotors at 10.4" and some at 11.6?
EBC 3GD Series Sport Slotted Rotors #GD239
Rear 10.4 in. Dia.
or
EBC 3GD Series Sport Slotted Rotors #GD550
Rear 11.6 in. Dia.
Can someone clarify which is right? I have until tonight to either confirm or cancel the order and then fight with them to get my money returned.

My concern would be the proximity of the exhaust pipe to a wider calliper. As it is, the best I can do is about 3/4 of an inch gap between the pipe and the calliper at the nearest point. If this mode were to be done, then routing the exhaust under the cage would be a very good idea.
FWIW, unless you are racing, this is a totally unnecessary mod, in my view. Decent solid discs and EBC Redstuff pads all round will stand up to very hard road use easily.

The caliper-to-pipe spacing has always worried me a bit. Even with original configuration I've oft thought of wrapping that area of the pipes to keep some of the heat away from the calipers.

Thanks for the replies, I've ordered my 'overkill' brake kit, thankfully I don't have rear exhaust pipes to deal with. For people that do, or if you happen to be in a position to remove your entire system the cost for thermal coatings is relatively cheap, I'll be coating my new system before install, leaves a chrome like finish from manifold to tip. Wraps are nice but subject to damage and unraveling over time.

Did you mean your exhaust has been, or will be, re-routed and not go through the cage?
