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.

I really like the idea, and the one you have looks REALLY clean.

However with that said, I don't take my car above 110 (or really, above 85 most of the time). Even the stock GT engine will only get you up to 120. I would understand a little bit more if we were achieving speeds of 150+, but I don't think our cars have enough power to really use this to their advantage.

However, it does look really sweet. I'm glad someone did it, I just wouldn't find it as practical as it should be (for me at least).

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.

^^ another reason (appart from the tank issue why he is talking gtfour specific^^

No particular reason. TBH we're quite happy with this universal one. It's proven to be effective on track with other cars already and it does the job. however it's not the most visually appealing and I'm curious if anyone else has tackled this challenge for the GT4.
The GT4 isnt the only car which has the same like a highbumper and low tank. The RX7's also use brackets to mount it's diffusers and it works better as a under car spoiler with the gap.
If this diffuser is fitted to a non GT4 6G, it'll sit flush to the bumper and looks alot better then the GT4.
