I have been looking at the DIY Aero thread on Miata turbo.net and I thought we should have one like that in our racing section.

So here is a template to help others in the future.

Would be awesome to post up your wing set up as well. Even if its run of the mill type set up.

 

I like this thread idea! I'll post up my splitter and wing once I get them all finished and have some lap times to compare.

 

Sounds like a plan.

 

Name/Description: S~Factor Fabrication Race Splitter for CR bumper (~5" past bumper)

Materials used: 12 gauge Aluminum
Size/thickness of materials: .082"
Bracket location: Wasp race bracket off frame rails, bolted to radiator support, 2 - Longacre Splitter supports, 2 - modified Wasp splitter supports
Tracks tested on: MSR Cresson 1.7 CCW

Name/Description: Voltex Type 7 GT wing
Dollars spent: $1600
Hours spent: 2
How effective: 2
Materials used: FRP trunk supports, Aluminum brackets, Carbon Fiber wing
Size/thickness of materials: unknown
Bracket location: Voltex center mount with FRP trunk reinforcement
Tracks tested on: MSR Cresson 1.7 CCW

Set personal best with this setup, granted I'm fairly new at tracking so majority of the improvements are from driver.

 

Has anyone ever done a DIY flat underbody for the S2000? Is it even worth the time? There's a $3k carbon fiber kit out there for the S2k, but I was thinking of doing something similar made out of alumalite or something similar for fun.









^I like how it comes out the side similar to the side steps people install on the car.

I've seen people using corrugated panels online too:



I would like to build something that would tie from the front splitter to the rear diffuser, with side steps as well. It would be made in pieces and it could be taken off for street driving, if desired. Thoughts? How effective is it (worth the time/money) to do a completely flat under body for an HPDE car?

 

I think it all depends on what you can do for the cost. remember you will need to find solutions to cool the trans and the diff. Making sure all three main unit connect together semi easily if you plan to take them off that often. I think its a good idea though.

 

I'll be re doing my ducting and some aero upgrades in the coming weeks in preparation for UTCC and GTA.
