I've been reading through Andrew Brilliant's posts, and there's lots of great info, but most of the pictures are gone. I don't want to go quite as high-end as he did of course, I'm an IT person, not an aerodynamics expert. I'll consider pro CFD eventually, but want to DIY for now.
I'm not going to be RACING in any particular series, this is mostly for fun, open track days around the Pacific Northwest and California.
I have a decent understanding of open-wheel aero from my days many years ago racing Formula Ford and Formula Continental, but closed-wheel aero is a whole new thing to me because of all the limitations.
I would like to emulate the aero build of something like the Spoon FD2 Civic. I'll be running moderate power levels (Evo III 16g), fender flares, 285's currently (will drop to 275's probably next set of tires).
Does anyone have pictures of a full flat floor on a 2g GST?
I'm thinking for the rear to do a partial cutout of the OEM rear bumper, cut out the spare tire well, install a full diffuser, and have the exhaust exit higher up, just above the diffuser, in the center (around where the factory license plate goes). Can anyone see any potential issues with running a setup like that?
I know dumping the exhaust before that would be better, but for the next few years it's not going to be a full track car, will be driven occasionally on the street. So I'd like to keep a muffled exhaust for now. I can't see any routing issues coming up since I'm FWD. Thoughts?
Thanks!
