I know. But it would be fun wouldn't it?
I think the best way to attack it, would be to first establish those wheel arch vents, using thin gauge modelers card, and then go about adding putty and sculpting. The rear diffuser doesn't look too hard, as it's all pretty much straight edge (again, modelers card, same for the wing).
Don't know if you've seen FPR's finished cars, so here's a couple of pics
Any pics of either of those two, guys? Did you notice whether they had to adjust/chop or extend the wheelbase?
Regardless, it would indeed make a fine pre-made wide arch set. 👍
Speaking of Miata's, next big project and it might be that extra Miata you sent me.
Aside from the unclean detailing, that turned out pretty damn nice. Thanks for sharing.
