Project MX-5 RS...

In the short term, the interior is getting race seats. Black and tan will have to suffice for a while. That's allow the budget will allow.

Bring it by TDR. I'd love to see it again in person.

[MoonieGT]

Will do. I need to come see you about seats anyway. I think the one I had picked out may not work out.

[Sharpie]

Looks sharp!

I am not green.

Great job Stevan.

What size wing do you have 57"?

[MoonieGT]

It's the GTC-200 that 949 and Goodwin sell. I'm not sure what the dimensions are. The GTC-300 is the bigger one that some serious TT guys run.

Looks great!

Nice seeing your car tonight at Keller's. Rogue did an outstanding job!

Do you like the APR wing? I have been looking at adding aero and cannot decide on 2D or 3D design.

If the rules allow it, you want a dual element wing. The slot between the wings allows the second wing to be run at a much steeper angle without stalling. Dual element wing produce much more down force than single wings of the same size.

You will need/want front aero to balance the car. My car is far from dialed in at the moment. When I went from 7" rims with 195 tires to 9" rims with 225 tires I had to raise the car up a bit to get rid of some tire rub issues. I have not had the car realigned since that time. I also need to swap springs from 550/350 F/R to 700/400. When I got my ASTs, the car was my only car for a bit, so I went on the softer side spring-wise. Now that I'm running much wider rubber, I need the stiffer springs.

I added the wing at the same time as the wider wheels, so it's hard for me to know exactly what effect the wing has. However, I can say that the car has understeer as is at corner exit. It turns in great, but coming out of the corners (e.g., little and big bends at MSR) I'm getting understeer. The car is super stable and predictable through those corners, but I'm positive the car will be faster through those corners with less understeer. I plan on swapping springs and doing an alignment/corner balance. I'll then reevaluate the wing. I honestly didn't mind the way the car drove this last weekend. Confidence levels were high as the backend never showed signs of moving. I was still able to get the car to rotate nicely on the entry and middle portion of rattle snake (1.7 CW). For reference, on 225 RS3, AST coilovers, stock swaybars, and stock power my best lap of the weekend was 1:30.9.

For someone of your skill level and car performance level, you'll want a front splitter or canards to go with the wing.
