Standing by for feedback from customers on wing risers and a group buy.

Yeah curious what the risers do to needing additional front aero? Having visibility out the rear would be nice!

I have RSNV risers on my GT4 and don't notice any "unbalanced" issues with the front. I'd guess you have to be driving 9/10ths and be extremely capable to start feeling any imbalance.

The wing is pretty much out of view with the risers in place on my friends car. This will add about 30 pounds of downforce from what I can tell by others CFD analysis. This will be at 186 mph which calculates to about 6 pounds of downforce at 80 mph. I wouldn't worry about it. Manthey will also sell you a carbon fiber rear spoiler that adds a similar 25-30 pounds of rear downforce. This can be had separately on its own and they don't worry about any significant imbalance in the car. They won't break up the full aero package though.

So the bottom line is that it appears that you don't need to add anything to the front when installing these risers. If however you feel a bit of understeer or push, then by all means add a bit more aero to the front.

That's great. Do you know which down force level he keeps it at?

I didn't add any additional down force for either my 981 or 718 GT4 when I had the wing risers on the car but I could definitely feel the car was more planted in fast sweeping turns (80-120mph) at my local tracks and didn't suffer any understeer in the front.

Is it possible for you to make a complete new front side trim piece that incorporate spoiler and has dive planes attached? That would eliminate the need to glue/attach pieces together.

It was an honest mistake. They forgot a layer of padding. The foam is custom made and the risers are sandwiched between the layers. They forgot a bottom layer and the Alum rubbed together taking a little of the powder coating off.

they were very responsive though and we seem to be resolving it now
