Prototype front splitter

My carbon fiber expert aka Numero Reserve just finished making the rather aggressive front splitter that I was itching to get . We will test it out next week at the track then convert it to a full carbon fiber version ?

That's a very aggressive looking front splitter, I like it!

How far back does it go on the bottom and what mounting points did you use?

Track days at Area27 here in BC , Canada. The track is designed by Jacques Villeneuve. Check it out on YouTube.

I'd be interested to see the design of your splitter. @ReDRuM 's is similar to what I'd like to build.

Similar to what I'm running. It's just a 6mm sheet of polymetal bolted to stock locations. Minimal effect from what I can discern. The fact that there's a huge hole in the space directly above the middle of the splitter kinda weakens its ability to build a high pressure zone above it.

I wish someone would design one similar to the S3 Elise PB-Racing splitter used in the Cup races in Italy 😩

Well , I'll let you guys know how it feels next week. I do know that prior to having the splitter , the larger canards were creating significant downforce. Unfortunately, the brackets couldn't hold them up , even after further reinforcement. Now those canards are supported from below by brackets on the splitter.
I actually haven't looked at the aerodynamics of a splitter. I get the idea of smoothing out air flow and creating negative pressure under the car. By "pushing" air through the hole in the middle above the splitter should help achieve this ... No?
I guess a sloped lip would help and we might configure this into the design.
Do you think the lip should protrude even further? I think I need some type of fluid dynamics software

I can clearly state that the splitter/canard works. Turn 2 at Area 27 is a long sweeping turn just after a top speed straightaway. Pre splitter I felt comfortable at 120-125km/h. Now I can feel the front end sit deeper and I can push it to 135 with confidence.
On another part ,turn 11 , the track rises then suddenly drops into a 20 degree turn to the left. I hammered this section one time , compressed the suspension then "landed" having already made the adjustment for the turn. Needless to say , I had an exciting 5 seconds that felt like a minute. Anyhows, now when I hammer the car is feels more glued as I hammer it... Without any changes to the dampers.
I'm very happy.
Would anyone want me to set up a group purchase for the splitter in carbon fiber , or Alumalite ?

I think it looks great, if it's functional as it appears you should be able to drive upside down

Cheers!

Wouldn't eliminating some of the front under body holes/covering some more of the front suspension help?

Thank you so much for posting this picture. I'm building a splitter this winter. Covering up that area in the front suspension is a GREAT idea!

If you need that much down force, and this provides it, great.

If you're just shooting for aesthetics over function...hmmm.

Now your car needs proper skirts and front suspension block off plates.

I can help with that I'm located in Quebec.
