I understand that RUSH now offers a both wind deflectors and wind diffusers for the SR. Could someone explain the pros and cons of each? Pictures would be great and also the costs of each.
I'm not sure of the difference, but I have installed my own version of a wind deflector. You can see it right in front of the seat mounted on the front body panel. They don't have to be very large/tall to be very effective. Mine is probably barely 1" tall, and works wonderfully. It really is quite effective at reducing the wind buffeting. I'm 6ft, but try and get as low as possible in the chassis both for wind and protection.
Nothing fancy... I think it is 1/8" thick plexiglas and it is held on my just 3 or 4 very small bolts. We custom built it before the Rush version was finalized. I probably paid more to have it custom done, so I'd just get the Rush version. This isn't McLaren Elva of engineering....
