This half top (SoftBits) came with the r400 but did not have the zip out for easy entry... I knew I would not use it unless it was so equipped. My local Saddlery did this for me in leather (of course) but in Az that won't be an issue and as it overlaps like the original ( full length round seal and hook/loop tape with heavy duty zipper) even in the rain it would seal. Now it will get some use come summer.

More than 10 bucks....sent you a msg. as that is between the builder and the customer.

The dif is here and arrived safely...tariff was over 400 bucks.... expected. I am sending the r400 to Josh in Denver for the install end of April. I just do not feel like the effort at this stage. Once did everything but no major stuff anymore. I'll update when the car is sent.

Steve will build my Dif this coming Monday.

They are quite a bit bigger especially the section that angles downward...that, I hope, assists with the turbulence reduction...damned can't hurt. I already have mounting parts so it wasn't expensive for the wings alone.

Thanks.... bought a set.

Where do you get those oversized wind wings?

Thanks gents...good info and pics....

I have the side wing deflectors but didn't notice a great deal of wind reduction...as demonstrated by that link you posted. You might be right about half doors not being the solution too .....

It appears we are going to remain curious..... I may mock up something for a test drive before I invest or get serious about the issue.

I have looked online but will ask here too as many who were chatting about this had the racing short screen. When I took the doors off the r400 and put the wind wings/deflectors on I was taken by surprise at the amount of turbulence, this with the stock full windshield. In my other 7, with the clamshells covering the front wheels, the turbulence is a great deal less...not really an issue doors off. They really do catch a great deal of wind and direct it elsewhere. Obviously not efficient for drag but great for the street. The cycle fenders/doors off r400is a wind storm. Has anyone gone the 1/2 door route with full windscreen? If so, how much did they help in your estimation. BTW, I do a lot of 60mph driving locally in and around our town as we have 65mph state roads and Hwy 73 (I pull out on 73 going to town from our drive)

Pretty straightforward. The injectors were stock but they were over designed and gave great PSI under load. I did mount a gauge for that but it was never an issue.

I supercharged a first gen Miata years ago.... that is really the way to go if you want it to move.
