You won't necessarily have to, I just want you to know about the things you'll have to measure/analyze.

Tobin at Kore3 does a hybrid C5 brake setup with slightly smaller diameter rotors that will fit in 17" wheels I believe. But, if you're going to do a 285 front tire, you're going to end up needing wheels wide enough to hold them. With 9"+ wide wheels, I believe they'll interfere with the tie-rod unless you're using wheels with a lot of negative offset.

You can refer to the OneLap Camaro thread to see how David P. had to modify the steering arms extensively to work around this issue. Actually, he used the speedtech arms as well, so if you haven't read through that thread, you really should.
