I also have an 89 coupe. I'm running SN95 front, but haven't gotten around to the rear conversion yet. I'll end up going with the North Race Cars Brackets etc. I've also got to work on the rear suspension setup, but I'm spread pretty thin with other projects right now.
I've also got to come up with a different wheel combo, but the '98 splits are working OK for now!
Keep us update with pics!
Later,
Brandon
