Thanks mate. I'll look into a spoiler then.
Time to google away to fab one up.
Got any quick hints on angles for a track where max I'd see is maybe 180kph?

No air dam,stock na bumper with gv lip and splitter. I just don't want to put the splitter on and have the rear end want to come meet the front haha.

Splitter or Air Dam – Which Design is Best? Hancha CFD


Just when referencing that for design dont forget that 6 has a larger surface area on the splitter than 4 due to how to test was setup so its not conclusive on which style airdam is better.

I would disagree - not about the difference in splitter surface area but in the (lack of) conclusion about which config is best. 6 is clearly better than 4 in terms of drag. Even if you tweaked 4 to match 6's downforce, 6 still wins the L/D contest by a big margin.

I have used both 4 and 6 without changing anything else to the car and 6 has allowed for a higher top speed but about 3-6 km/h.

Was there any noticeable difference through turns at high speeds?

Hey guys, so just some relevant facts on my car and then ill get into my dillema

330whp 310wtq 3.63 rear EFR6258 20psi
XIDA 700/400 Gen 2
15x10UL w/ 245 Maxis RC-1
2550lbs with Hardtop installed

I was looking at the BBFW lexan spoiler, but a friend gets deals with some distributor and can get me a GTC200 with risers and a gurney flap, for $865 shipped which isn't bad at all. I know I'll have to build some kind of front aero to balance either setup, but just looking to get some insight on what people have tried before. I know the BBFW will be functional, but probably not AS functional as a proper wing on uprights.

What would miataturbo do? Do I go for the Lexan spoiler or for the GTC wing? Do I use the risers or not? I've heard of some issues with the stands being designed for an NA trunk and not really working on an NB too well. Should we get just the wing and try to make custom mounts for it? Chassis mounts? So many dilemmas here

I do have a spare trunk lid for either setup since I only do maybe 5 track days a year and the rest of the time is just spent on the street and cruising around. Probably would not permanently run either wing unless I loved the look

For front bumper, I was thinking of just building a giant plastic dam, basically similar to the Super Miata setups that most have. I can pick up a spare Ti bumper for the MSM with a smashed bottom, cut it along the fender line, and then use rivets or something to attach a giant front dam similar to 949racing's Crusher IIRC. Then, use alumalite to build a diffuser that will mount to the subframe and sit flush with the bottom of the front bumper, and stick out a few inches. Not sure on details with this, but something like #6 from that pic ThePASS posted. I am leaning towards the BBFW just because of cost and other expenses I have with school but basically wondering if the GTC200 is really worth 3x as much money.

850 shipped doesn't seem like a special deal tbh. The gtc-200 isn't a fantastic wing in terms of L/D. It will be effective if you keep it high but at a significant drag cost. The bfw spoiler is functional and the price is right. For me I would go with a bfw spoiler and/or save money for a GT-250. I wouldn't bother with anything in between those.

Supermiata air dam is effective/cheap/worth it. A splitter with the air dam is better to balance a wing. You're still going to want a plywood undertray behind the SPM air dam to get the most out of it.

To be fair the same package shipped from 949 was 1080 or so.

I understand why a splitter behind the bumper is needed, airflow and it reinforces the bottom of the bumper. However, what's the advantage of plywood over alumalite in that department?

Trust me, I drool over that and that's going to be THE wing I get down the road. Right now, even considering the high cost of the blackbird spoiler, and the spare bumper I'm getting, I don't expect to spend more than $500 on both aero pieces. I'm not a very experienced track driver at this point so I figure starting small with simple aero mods is a good way to get an understanding of it.

I did order the blackbird spoiler and am going to start figuring out the front bumper next week. My friend already has alumalite we can use for the splitter so I'm just waiting to hear why/if plywood is significantly better, otherwise I'll roll with what we have for now. Found the HPDE stuff for around $30 for a large piece to do the bumper. Sound right?

ah, ok, that makes sense, both front and rear for 500 is great.
