First I would like to thank John over at Fabspeed for working with me to get a set of risers on the GT4 in time for one of the two events I was attending recently, and of course a special thanks to his whole team who provided something you'll see a little later in the article. So first let's start with the risers themselves, here is a picture, black anodized aluminum with a textured finish similar to the stock factory risers:
The holes are chamfered just like the factory risers and the hardware that Fabspeed sends is a pretty close match to the factory hardware, you'd be hard pressed to spot the minor differences. The first order of business was to take off my existing wing so that I could add the new riser extensions to the factory risers. This is accomplished by removing two bolts (T27 if I recall correctly) from the fitting just below the wing. Here is a "Before" picture of the factory wing at factory height:
I also took a picture from sitting in the driver's seat looking out the back window so you can see the wing at factory height does block some of your vision to the rear of the car:
Once you remove the factory wing I found it easiest to lay it on a soft flat surface like a sofa or bed so that you don't scratch it up but can also move around it and attach the new risers. If you look closely at the hole in the factory wing brack it is actually 2 holes drilled so as to allow you to set the angle of attack on the wing to a higher or lower degree (factory setting is low). I left this setting alone because if you change it you are also supposed to adjust the front splitters on the car to compensate.
Next simply attach the new wing extensions from Fabspeed using the factory bolts at the top. When you attach the riser bracket to the factory riser you can use the additional bolts provided by Fabspeed, although technically there is no reason why you couldn't reverse that order if you prefer.
Once attached to the wing it is time to connect the Fabspeed riser to the factory riser. This is probably the most challenging part if you are trying to do this job yourself. If you have someone to help you then this is super easy, but by yourself you'll need some method of stabilizing one side while you attach the other due to a gap between the risers and the factory brackets. There is enough flex in the system to allow you to line them up, but doing so by yourself is a hassle...unless you have some handy dandy chopsticks. What I did was use chopsticks on one side while I attached the bolts on the other, you might find your own creative solution, grab some chop sticks, or simply grab a friend to help you.
I know Fabspeed is looking at modifying their riser extension bracket in the future to have a bend/curve but no word as of the time of this article when that might be. It's a minor issue but one I felt I should point out so that installers can be properly prepared. After I tightened up the bolts here is the After photo:
Here is the same view from inside now with the wing raised:
As you can see, the view is unobstructed now. Of course if someone behind you has their brights on, you might wish for the wing back to obstruct them!
Last but not least see if you can spot what is different in the next picture:
Didn't spot it? Here this next image might help:
The upper riser is now no longer just a diagonal line to match the lower factory riser piece but rather a custom "X" pattern to go with my Racer X theme for the car. How did this happen? It happened because Fabspeed sent me 2 sets, the factory "normal" set that you see installed above and the custom "X" set to match my theme. It's probably not well known, but Fabspeed can make CUSTOM parts for you. Yes, there is an added cost (Talk to John at Fabspeed about this) but if you want to do something truly unique for your car then Fabspeed can make it happen.
