Really eh? The chassis mount made that much of a difference? I always felt for trunk I hopefully wouldn't need it as much. Like when you push down on the trunk there isn't really any play I can feel. Seems to go straight to the suspension. Front 100% needed that bumper will rip right off lol.

I got the impression that AJ took the items off his product list that were not the best design aerodynamically. He just recently took off fender louvers after a windtunnel that showed the race louvers were better. That's my assumption for why he doesn't offer the front lip anymore.Originally posted by sc_tr0jan_m3 View Post
He mentioned to me that his apex 8(8inch cord) produces more downforce then the nine lives 9.5 in cord wing (he didn't directly name them but from what he told me I could clearly assume it was that company). And by the look of the airfoil it looks like it will have minimal drag. Just a well designed airfoil.Last edited by SandeepM3; 01-02-2021, 06:55 PM.2003.5 Titanium Silver / Black 6M/T (Gone)

There are rubber stops which the hinges and bottom of the trunk lid sit on.Originally posted by SandeepM3 View Post
But I learned the hard way the front mount points on the trunk lid lift up, they do not push down. Pushing down is one thing...try pulling back on the wing. You’ll get some flex.

Oh interesting. I'll try that when I get the wing mounted, but just pulling up on that side of the trunk with the edge of my fingers did have some play. So would be much work with some leverage the wing would provide. Damn. I really didn't want to make a chassis mount for the rear. lol2003.5 Titanium Silver / Black 6M/T (Gone)

Front splitter mounting. Old mounts were aluminum which didn’t last. These mounts are steel. Steel plate with a turnbuckle to adjust the height.
Then I used some gas shocks from McMaster-Carr for the sides.

Safe to assume the foamcore/carbon is stiff enough that is doesn't need anything to stop the front from bending down?2003.5 Titanium Silver / Black 6M/T (Gone)

If you want some inspiration, my colleague is on Instagram as TimeAttackM3 and starting to do some proper mad things with his.Comment

I could get by without support rods on the front but there would be some flex. Mostly because the mounts. You could add more bracing which adds more weight.Originally posted by SandeepM3 View Post
Easier and less weight to add the support rods.

Here are some resources to help you guys get an idea of what works. Aero can be pretty useless or counter productive when done wrong, however, it's not that hard to avoid stupid aero. Perfecting a set up will require some R&D in a tunnel but having an idea of how air flows can put you in the ballpark of the educated. There are some real weird time attack cars out there simple because they didn't research how air flows around cars.
