I compared Sparco R100 dimensions to the Corbeau A4. The A4 has a fair number of installation in the C5 and is considered to "fit" in the C5 although the lever to recline the seat is so tight, apparently its not functional. If I understand correctly if you swap passenger with driver side the lever is on the outside rather than the inside and is better.
The R100 is very comparable to the A4 in size, just slightly smaller in the shoulder width, total seat width and seat-base depth. as far as I can tell looking at the published dimensions, the R100 should fit n the C5.
One questions I have that I have not been able to answer is which seat will provide more headroom when installed. The A4 has a "shaved" option ($50 per seat) which lowers your position in the seat by 1". I'm only 6 foot tall and my helmet is brushing to head liner in the lowest setting in the stock seat.

Pricing is pretty comparable. The Sparco doesn't appear to accomodate a 5-point harness ( no Slot). The A4 has that as an option ($50 / seat) not priced in the comparison. I don't see a lumbar support option for the R100 either, which the A4 does offer.

Carbeau A4
I'm re-opening this ancient thread, just curious if anyone ever put these in, particularly with regards to seat height. My helmet is in the roof with stock seats at the track... looking into these or A4s for a weekend/8ish track days per year C5.
There is only one guy on the forum who installed these in a C5, as far as I know. You already replied in his thread. His installation details were very specific. He even addressed height issues.
