Not fitted at all unless you have a flat floor fitted it's pretty much just cosmetic on a scoob so will in fact slow you down due to extra weight!

Hi there

Everything depends on the budget,you can choose from HT Autos,then bit expensive is OEM JDM Rear Diffuser,then you have Varis and Voltex Diffuser,then is there APR rear diffuser and at the end is there is HKS Kansai Service rear diffuser

Rear diffuser is not only cosmetic reasons,but as most of the parts like rear wing and splitters start works above motorway speeds and they're not working bellow or under 70MPH,most of the diffusers start to work above 100MPH

Somewhere on the Youtube is video,where Japanese magazine tested RA-R with and without the Rear diffuser and car with rear diffuser has have bigger cornering speeds like without the rear diffuser and with rear diffuser car has been more stable in higher speeds like without the

And I would add,its important at least have Rear diffuser which has been tested in CFD/Aero Tunnel

In normal motorway speeds rear diffuser will or can cause drag like rear wing or any splitter which you are have already fitted
