Diffuser on 6G Options

[yellowchinaman]

Just out of curiosity. Has anyone in the US or in Europe installed or fabricated a Diffuser for their Gen6?
We've fitted a universal Diffuser to our GT-Four however looking at re-designing a Celica specific due to its low tank.

Actually you dont have to go high speeds to benefit a diffuser. At average speeds of around 30-40mph when I fallowed this car in the rain, one obvious thing we noticed was the way the air reacted in the air.
The rain water was being lifted and blown out the back smoothly like line of haze. (Difficult to explain) where as before whendriving in the rain, when lookingin the rear view mirrir, you just see massive sworls of rain being flicked up.
This has improved the airodynamics of the bottom rear of the car reducing alot of drag. This means is should help improve your MPG as we've noticed last weekend during motorway driving.

If you look at new cars like the toyota prius, they too have a simple diffuser in the rear to do the same job to improve fuel efficiency.
And if you have a low down car with fron splitters, and side skirts, you dont need to go fast to get the Venturi Effect which creates the down force.

I'll definitely take your word for it. So from your experience, it's actually better to use this diffuser with a body kit installed (ie. TRD front and rear splitters with stock skirts)? Let me know what the MPG change is, if it's significant (even 1mpg) I'd definitely be interested.
