Looks good without the spoiler but how has it affected the handling of the car.

I personally prefer the idea of the later spec spoiler, at least test fit it so we can see what it looks like

I was kinda hopng everyone wouldnt like it without the spoiler lol.

Will be picking it up today so when the rain stops tonight......IF the rain stops tonight I will try a test fit.

pablo.....apparently without a wing the downforce on the car is significantly reduced but only at high speeds.

That said Alex (Alexb) sent me a message saying that RX7s were tested using no spoiler, a re-am gt one and the new 99 spec one. With the new spoiler it made a huge difference to rear downforce.

Here is a table of info based on the 4 settings of the spoiler.

ANGLE OF ATTACK FRONT DOWN FORCE REDRAWN FORCE
1 deg 0.045 0
5 deg 0.047 -0.025
10 deg 0.051 -0.058
14.5 deg 0.053 -0.075

Edit....the above is formatted perfectly on my post but for some unknown reason it comes up looking odd on here, assume the numbers are under the 3 columns.

Here's the info copied from the original FDUK post:

"just watched an option video and they test an FD with no wing, A type R adjustable wing, and a Re Amemiya GT wing.

They did a lap of Tsukuba. They gave a speed and G force gained round the final, fast, corner and a lap time. Here are the results;

No wing - 102kmh 0.91g 1.10.000

TypeR - 112kmh 1.07g 1.09.417

GT - 117kmh 1.14g 1.08.771

So it seems that a good quality rear wing can make a difference and its nice to see some results that really back that up rather than the general hear say!!"

Dunno if this circuit-related stuff will be relevant for you though mate?!

Cheers for the pics Alex, the pump looks exactly the same...as for the rest of the bits....hmm..not got those !! Will try and find a fitting guide.

Anyway...I test fitted the spoiler, because the weather is crap at the mo I cant take it outside so you'll have to cope with these inside garage pics !!

How evil does this rear end look now ?!!!!!?

Absolutely chuffed !!! And I love it 100 times more than the no spoiler look.
Hopefully the weather will be better tomorrow so I can get some good shots of it from the side. Looks weird when looking out the back window.

Loving it !!!!!!!!!!!!!!!
